The historical perspective is useful for establishing trends in types of MSW generated and in the ways it is managed. In this Executive Summary, we briefly describe the methodology used to characterize MSW in the United States and provide the latest facts and figures on MSW generation, recycling, and disposal. In the United States, we generated 243 million tons of MSW in 2009—eight million tons less than generated in 2008. Excluding composting, 61.3 million tons of MSW were recycled, a slight decrease of 0.5 million tons from 2008. The tons of food scrap and yard trimmings recovered for composting were 20.8 million tons in 2008. The recovery rate for recycling (including composting) was 33.8 percent in 2009, up from 33.4 percent in 2008. Although the tons recycled and composted decreased in 2009, the tons generated also decreased resulting in an increase in the recycling rate (see Tables ES-1 and ES-2 and Figures ES-1 and ES-2). MSW generation in 2009 declined to 4.34 pounds per person per day. This is a decrease of 4 percent from 2008 to 2009. The recycling rate in 2009 was 1.46 pounds per person per day. Discards sent for combustion with energy recovery was 0.52 pounds per person per day. Discards sent to landfills after recycling and combustion with energy recovery declined to 2.36 pounds per person per day in 2009. This is a decrease of 3.3 percent from 2008 to 2009 (see Table ES-3). ------- Executive Summary Table ES-1.

The state of the economy has a strong impact on consumption and waste generation. Waste generation increases during times of strong economic growth and decreases during times of economic decline. WHAT IS INCLUDED IN MUNICIPAL SOLID WASTE? MSW—otherwise known as trash or garbage—consists of everyday items such as product packaging, grass clippings, furniture, clothing, bottles, food scraps, newspapers, appliances, and batteries. Not included are materials that also may be disposed in landfills but are not generally considered MSW, such as construction and demolition materials, municipal wastewater treatment sludges, and non-hazardous industrial wastes. ------- Executive Summary MUNICIPAL SOLID WASTE IN PERSPECTIVE Trends Over Time Over the last few decades, the generation, recycling, and disposal of MSW have changed substantially (see Tables ES-1, ES-2, and ES-3 and Figures ES-1 and ES-2). Annual MSW generation continued to increase from 1960, when it was 88 million tons, until 2007. After 2007, the tons of MSW generated started to decrease. The generation rate in 1960 was just 2.68 pounds per person per day; it grew to 3.66 pounds per person per day in 1980, reached 4.72 pounds per person per day in 2000, and decreased to 4.67 pounds per person per day in 2005. Since 2005, MSW generation per capita rate has continued to decrease. The generation rate was 4.34 pounds per person per day in 2009. Over time, recycling rates have increased from just over 6 percent of MSW generated in 1960 to about 10 percent in 1980, to 16 percent in 1990, to 29 percent in 2000, and to about 34 percent in 2009. Disposal of waste to landfills has decreased from 94 percent of the amount generated in 1960 to just over 54 percent of the amount generated in 2009. MUNICIPAL SOLID WASTE IN 2009 The U.S. Environmental Protection Agency (EPA) uses two methods to characterize the 243 million tons of MSW generated in 2009. The first is by material (paper and paperboard, yard trimmings, food scraps, plastics, metals, glass, wood, rubber, leather and textiles, and other); the second is by several major product categories. The product-based categories are containers and packaging; nondurable goods (e.g., newspapers); durable goods (e.g., appliances); food scraps; and other materials. See Figure 1-B in Chapter 1 for product category definitions. ------- Executive Summary Materials in MSW A breakdown, by weight, of the MSW materials generated in 2009 is provided in Figure ES-3. Paper and paperboard made up the largest component of MSW generated (28.2 percent), food scraps were the second-largest component (14.1 percent) and yard trimmings were the third largest (13.7 percent). Metals, plastics, and wood each constituted between 6 and 13 percent of the total MSW generated. Glass made up 4.8 percent, rubber, leather, and textiles combined made up 8.3 percent of MSW, while other miscellaneous wastes made up 3.5 percent of the MSW generated in 2009. Figure ES-3. Materials Generation in MSW, 2009 243 Million Tons (before recycling) Food scraps 14.1% Yard trimmings 13.7% Other 3.5% Wood 6.5% Rubber, leather & textiles 8.3% Paper and paperboard 28.2% Plastics 12.3% Glass 4.8% Metals 8.6% ------- Executive Summary A portion of each material category in MSW was recycled or composted in 2009. The highest rates of recovery were achieved with paper and paperboard, yard trimmings, and metals. Over 62 percent (42.5 million tons) of paper and paperboard was recovered for recycling in 2009. About 60 percent (19.9 million tons) of yard trimmings was recovered for composting or mulching in 2009. This represents about a five-fold increase since 1990. Recycling paper and paperboard and yard trimmings alone diverted about 26 percent of municipal solid waste from landfills and combustion facilities. In addition, about 7.2 million tons, or 34.5 percent, of metals were recovered for recycling. Recycling rates for all materials categories in 2009 are listed in Table ES-4. Table ES-4.

Neg. = Less than 5,000 tons or 0.05 percent. ------- Executive Summary Products in MSW The breakdown, by weight, of product categories generated in MSW in 2009 is shown in Figure ES-4. Containers and packaging comprised the largest portion of products generated in MSW, at 29.5 percent (71.6 million tons). Nondurable goods were the second-largest fraction, at 22 percent (53.4 million tons). The third-largest category of products is durable goods, which made up 19.2 percent (46.6 million tons) of total MSW generation. Figure ES-4.

This table shows that recovery of containers and packaging was the highest of the three product categories—47.8 percent of containers and packaging generated in MSW in 2009 were recovered for recycling. About 51 percent of all aluminum cans in MSW was recovered (37.5 percent of all aluminum packaging, including foil), while 66.2 percent of steel packaging (mostly cans) in MSW was recovered. Paper and paperboard containers and packaging were recovered at a rate of 62.4 percent; corrugated containers accounted for most of that amount. Approximately 31 percent of glass containers in MSW were recovered, while about 22 percent of wood packaging (mostly wood pallets removed from service) was recovered for recycling. About 14 percent of plastic containers and packaging in MSW were recovered— mostly bottles and jars. Overall recovery of nondurable goods in MSW was at 35.3 percent in 2009. Most of this recovery comes from paper products such as newspapers and high-grade office papers (e.g., white papers). Newspapers constituted the largest portion of this recovery, with 88 percent of newspapers generated being recovered for recycling. An estimated 74 percent of high-grade office papers and 66 percent of other commercial printing was recovered in 2009. Newspaper, high-grade office paper, and other commercial printing recovery increased in percentage from 2008 to 2009. Recovery percentages of the other paper products in the nondurable goods category also increased between 2008 and 2009, with standard mail* recovered at an estimated 63 percent, and magazines at an estimated 54 percent. Standard mail was formerly called Third Class mail by the U.S. Postal Service. ------- Executive Summary Table ES-5.

Overall, durable goods were recovered at a rate of 17.5 percent in 2009. Nonferrous metals other than aluminum had one of the highest recovery rates, at 68.8 percent, due to the high rate of lead recovery from lead-acid batteries. Recovery of steel in all durable goods was 27.9 percent, with high rates of recovery from appliances. One of the products with a very high recovery rate was lead-acid batteries, recovered at a rate of about 96 percent in 2009. Other products with particularly high recovery rates were newspapers (88 percent), corrugated boxes (81 percent), major appliances (67percent), steel packaging (66.2 percent), and aluminum cans (51 percent). About 35 percent of rubber tires in MSW were recovered for recycling. (Other tires were retreaded, and shredded rubber tires were made into tire-derived fuel.) RESIDENTIAL AND COMMERCIAL SOURCES OF MSW Sources of MSW, as characterized in this report, include both residential and commercial locations. We estimate residential waste (including waste from multi-family dwellings) to be 55 to 65 percent of total MSW generation. Commercial waste (including waste from schools, institutions, and businesses) constitutes between 35 and 45 percent of MSW. Local and regional factors, such as climate and level of commercial activity, contribute to these variations. MANAGEMENT OF MSW Overview EPA's integrated waste management hierarchy includes the following four components, listed in order of preference: 11 ------- Executive Summary • Source reduction (or waste prevention), including reuse of products and on-site (or backyard) composting of yard trimmings • Recycling, including off-site (or community) composting • Combustion with energy recovery • Disposal through landfilling. Although we encourage the use of strategies that emphasize the top of the hierarchy whenever possible, all four components remain important within an integrated waste management system. Source Reduction Our waste management hierarchy emphasizes the importance of reducing the amount of waste created, reusing whenever possible, and then recycling whatever is left. When municipal solid waste is reduced and reused, this is called "source reduction"—meaning the material never enters the waste stream. Source reduction, also called waste prevention, includes the design, manufacture, purchase, or use of materials, such as products and packaging, to reduce their amount or toxicity before they enter the MSW management system. Examples of source reduction activities are: • Designing products or packaging to reduce the quantity or the toxicity of the materials used or make them easy to reuse. • Reusing existing products or packaging, such as refillable bottles, reusable pallets, and reconditioned barrels and drums. 12 ------- Executive Summary • Lengthening the lives of products such as tires so fewer need to be produced and therefore fewer need to be disposed of. • Using packaging that reduces the amount of damage or spoilage to the product. • Managing nonproduct organic wastes (e.g., food scraps, yard trimmings) through onsite composting or other alternatives to disposal (e.g., leaving grass clippings on the lawn). Realizing the value of our resources, both financial and material, we have continued in our efforts to reduce waste generation. Recycling The second component of our waste management hierarchy is recycling, including off-site (or community) composting. Residential and commercial recycling turns materials and products that would otherwise become waste into valuable resources. Materials like glass, metal, plastics, paper, and yard trimmings are collected, separated, and sent to facilities that can process them into new materials or products. • Recycling (including community composting) recovered 33.8 percent (82 million tons) of MSW generation in 2009. • There were about 9,000 curbside recycling programs in the United States in 2009. • In 2009, close to 3,000 yard trimmings composting programs were documented. 13 ------- Executive Summary Combustion with Energy Recovery MSW combustion with energy recovery increased substantially between 1980 and 1990 (from 2.7 million tons in 1980 to 29.7 million tons in 1990). From 1990 to 2000, the quantity of MSW combusted with energy recovery increased over 13 percent to 33.7 million tons. After 2000, the quantity of MSW combusted with energy recovery has decreased to an estimated 29.0 million tons (11.9 percent of MSW generation) in 2009 (see Tables ES-1 and ES-2), less than the 29.7 million tons estimated in 1990. Disposal During 2009, about 54 percent of MSW was landfilled, similar to the percentage landfilled in 2007 and 2008. As shown in Figure ES-5, the number of MSW landfills decreased substantially over the past 21 years, from nearly 8,000 in 1988 to 1,900 in 2009—while average landfill size increased. At the national level, capacity does not appear to be a problem, although regional dislocations sometimes occur. • The percentage of MSW landfilled remained about the same as 2008. Over time, the tonnage of MSW landfilled in 1990 was 145.3 million tons (see Table ES-1), but decreased to 139.4 million tons in 2000. The tonnage increased to 140.9 million tons in 2005, then declined to 131.9 in 2009. The tonnage landfilled results from an interaction among generation, recycling, and combustion with energy recovery, which do not necessarily rise and fall at the same time. In general, as recovery increases, discards decrease. 14 ------- Executive Summary Figure ES-5.

The net per capita discard rate has decreased steadily since 1990. The 1990 rate was 3.19 pounds per person per day, the 2000 rate was 2.71 pounds per person per day, the 2005 rate was 2.61 pounds per person per day (Table ES-3). MSW management through recovery for recycling (including composting), combustion with energy recovery, and discard to disposal in 2009 is shown in Figure ES-6. In 2009, 82 millions tons (33.8 percent) of MSW were recycled, 29.0 million tons (11.9 percent) were combusted with energy recovery, and 131.9 million tons (54.3 percent) were landfilled or otherwise disposed. (Relatively small amounts of this total undoubtedly were incinerated without energy recovery, littered, or illegally dumped rather than landfilled.) 15 ------- Executive Summary Figure ES- 6.

Aside from reducing GHG emissions, which contribute to global warming, recycling also reduces air and water pollution associated with making new products from raw materials. By utilizing used, unwanted, or obsolete materials as industrial feedstocks or for new materials or products, we can each do our part to make recycling work. Recycling also provides significant economic and job creation impacts, a topic discussed at http://www.epa.gov/epawaste/conserve/rrr/rmd/econ.htm. 16 ------- Executive Summary Nationally, we recycled and composted 82 million tons of MSW. This provides an annual benefit of 178 million metric tons of carbon dioxide equivalent emissions reduced, comparable to the annual greenhouse gas emissions from almost 33 million passenger vehicles. But the ultimate benefits from recycling are cleaner land, air, and water, overall better health, and a more sustainable economy. The benefits of recycling and composting, such as elimination of GHG emissions, are calculated using EPA's Waste Reduction Model (WARM). Please see: www.epa.gov/warm. FOR FURTHER INFORMATION This report and related additional data are available on the Internet at www.epa.gov/epawaste/nonhaz/municipal/msw99.htm. 17 ------- Chapter 1 Introduction and Methodology CHAPTER 1 INTRODUCTION AND METHODOLOGY INTRODUCTION This report is the most recent in a series of reports sponsored by the U.S. Environmental Protection Agency to characterize municipal solid waste (MSW) in the United States. Together with the previous reports, this report provides a historical database for a 49-year characterization (by weight) of the materials and products in MSW. Management of the nation's municipal solid waste (MSW) continues to be a high priority for communities in the 21st century. The concept of integrated solid waste management—source reduction of wastes before they enter the waste stream, recovery of generated wastes for recycling (including composting), and environmentally sound management through combustion with energy recovery and landfilling that meet current standards—is being used by communities as they plan for the future. This chapter provides background on integrated waste management and this year's characterization report, followed by a brief overview of the methodology. Next is a section on the variety of uses for the information in this report. Then, more detail on the methodology is provided, followed by a description of the contents of the remainder of the report. BACKGROUND The Solid Waste Management Hierarchy EPA's 1989 Agenda for Action endorsed the concept of integrated waste management, by which municipal solid waste is reduced or managed through several different practices, which can be tailored to fit a particular community's needs. The components of the hierarchy are: 18 ------- Chapter 1 Introduction and Methodology • Source reduction (or waste prevention), including reuse of products and on-site (or backyard) composting of yard trimmings. • Recycling, including off-site (or community) composting. • Combustion with energy recovery. • Disposal through landfilling. As done in previous versions of this report, combustion with energy recovery is shown as discards in the Chapter 2 tables and figures. Overview of the Methodology Readers should note that this report characterizes the municipal solid waste stream of the nation as a whole. Data in this report can be used at the national level. The report can also be used to address state, regional, and local situations, where more detailed data are not available or would be too expensive to gather. More detail on uses for this information in this report for both national and local purposes is provided later in this chapter. At the state or local level, recycling rates often are developed by counting and weighing all the recyclables collected, and then aggregating these data to yield a state or local recycling rate. At the national level, we use instead a materials flow methodology, which relies heavily on a mass balance approach. Using data gathered from industry associations, key businesses, and similar industry sources, and supported by government data from sources such as the Department of Commerce and the U.S. Census Bureau, we estimate tons of materials and products generated, recycled, or discarded. Other sources of data, such as waste characterizations and surveys performed by governments, industry, or the press, supplement these data. 19 ------- Chapter 1 Introduction and Methodology To estimate MSW generation, production data are adjusted by imports and exports from the United States, where necessary. Allowances are made for the average lifespans of different products. Information on amounts of disposed MSW managed by combustion comes from industry sources and the press. MSW not managed by recycling (including composting) or combustion is assumed to be landfilled. In any estimation of MSW generation, it is important to define what is and is not included in municipal solid waste. EPA includes those materials that historically have been handled in the municipal solid waste stream-those materials from municipal sources, sent to municipal landfills. In this report, MSW includes wastes such as product packaging, newspapers, office and classroom papers, bottles and cans, boxes, wood pallets, food scraps, grass clippings, clothing, furniture, appliances, automobile tires, consumer electronics, and batteries. A common error in using this report is to assume that all nonhazardous wastes are included. As shown later in this chapter, municipal solid waste as defined here does not include construction and demolition debris, biosolids (sewage sludges), industrial process wastes, or a number of other wastes that, in some cases, may go to a municipal waste landfill. These materials, over time, have tended to be handled separately and are not included in the totals in this report. EPA has addressed several of these materials separately, for instance, in Biosolids Generation, Use, and Disposal in the United States, EPA530-R-99-009, September 1999, and Estimating 2003 Building-Related Construction and Demolition Materials Amounts, EPA530-R- 09-002, March 2009. Recycling (including composting) is encouraged for these materials as well. In addition, the source of municipal solid waste is important. EPA's figures include municipal solid waste from homes, institutions such as schools and prisons, and commercial sources such as restaurants and small businesses. MSW does not include wastes of other types or from other sources, including automobile bodies, municipal sludges, combustion ash, and industrial process wastes that might also be disposed in municipal waste landfills or combustion units. 20 ------- Chapter 1 Introduction and Methodology HOW THIS REPORT CAN BE USED Nationwide. The data in this report provide a nationwide picture of municipal solid waste generation and management. The historical perspective is particularly useful in establishing trends and highlighting the changes that have occurred over the years, both in types of wastes generated and in the ways they are managed. This perspective on MSW and its management is useful in assessing national solid waste management needs and policy. The consistency in methodology and scope aids in the use of the document for reporting over time. The report is, however, of equal or greater value as a solid waste management planning tool for state and local governments and private firms. Local or state level. At the local or state level, the data in this report can be used to develop approximate (but quick) estimates of MSW generation in a defined area. That is, the data on generation of MSW per person nationally may be used to estimate generation in a city or other local area based on the population in that area. This can be of value when a "ballpark" estimate of MSW generation in an area is needed. For example, communities may use such an estimate to determine the potential viability of regional versus single community solid waste management facilities. This information can help define solid waste management planning areas and the planning needed in those areas. However, for communities making decisions where knowledge of the amount and composition of MSW is crucial, (e.g., where a solid waste management facility is being sited), local estimates of the waste stream should be made. Another useful feature of this report for local planning is the information provided on MSW trends. Changes over time in total MSW generation and the mix of MSW materials can affect the need for and use of various waste management alternatives. Observing trends in MSW generation can help in planning an integrated waste management system that includes facilities sized and designed for years of service. 21 ------- Chapter 1 Introduction and Methodology While the national average data are useful as a checkpoint against local MSW characterization data, any differences between local and national data should be examined carefully. There are many regional variations that require each community to examine its own waste management needs. Such factors as local and regional availability of suitable landfill space, proximity of markets for recovered materials, population density, commercial and industrial activity, and climatic and groundwater variations all may motivate each community to make its own plans. Specific reasons for regional differences may include: • Variations in climate and local waste management practices, which greatly influence generation of yard trimmings. For instance, yard trimmings exhibit strong seasonal variations in most regions of the country. Also, the level of backyard composting in a region will affect generation of yard trimmings. • Differences in the scope of waste streams. That is, a local landfill may be receiving construction and demolition wastes in addition to MSW, but this report addresses MSW only. • Variance in the per capita generation of some products, such as newspapers and telephone directories, depending upon the average size of the publications. Typically, rural areas will generate less of these products on a per person basis than urban areas. • Level of commercial activity in a community. This will influence the generation rate of some products, such as office paper, corrugated boxes, wood pallets, and food scraps from restaurants. 22 ------- Chapter 1 Introduction and Methodology • Variations in economic activity, which affect waste generation in both the residential and the commercial sectors. • Local and state regulations and practices. Deposit laws, bans on landfilling of specific products, and variable rate pricing for waste collection are examples of practices that can influence a local waste stream. While caution should be used in applying the data in this report, for some areas, the national breakdown of MSW by material may be the only such data available for use in comparing and planning waste management alternatives. Planning a curbside recycling program, for example, requires an estimate of household recyclables that may be recovered. If resources are not available to adequately estimate these materials by other means, local planners may turn to the national data. National data are also useful in areas where appropriate adjustments in the data can be made to account for regional conditions as mentioned above. In summary, the data in this report can be used in local planning to: • Develop approximate estimates of total MSW generation in an area. • Check locally developed MSW data for accuracy and consistency. • Account for trends in total MSW generation and the generation of individual components. • Help set goals and measure progress in source reduction and recycling (including composting). 23 ------- Chapter 1 Introduction and Methodology CHARACTERIZATION OF MUNICIPAL SOLID WASTE: IN PERSPECTIVE The Two Methodologies for Characterizing MSW: Site-Specific Versus Materials Flow There are two basic approaches to estimating quantities of municipal solid waste at the local, state, or national levels—site-specific and materials flow. This report is based on the materials flow approach because site-specific approaches are problematic for national estimates. Site-specific studies. In the first methodology, which is site-specific, sampling, sorting, and weighing the individual components of the waste stream could be used. This methodology is useful in defining a local waste stream, especially if large numbers of samples are taken over several seasons. Results of sampling also increase the body of knowledge about variations due to climatic and seasonal changes, population density, regional differences, and other factors. In addition, quantities of MSW components such as food scraps and yard trimmings can only be estimated through sampling and weighing studies. A disadvantage of sampling studies based on a limited number of samples is that they may be skewed and misleading if, for example, atypical circumstances were experienced during the sampling. These circumstances could include an unusually wet or dry season, delivery of some unusual wastes during the sampling period, or errors in the sampling methodology. Any errors of this kind will be greatly magnified when a limited number of samples are taken to represent a community's entire waste stream for a year. Magnification of errors could be even more serious if a limited number of samples was relied upon for making the national estimates of MSW. Also, extensive sampling would be prohibitively expensive for making the national estimates. An additional disadvantage of sampling studies is that they do not provide information about trends unless performed in a consistent manner over a long period of time. 24 ------- Chapter 1 Introduction and Methodology Of course, at the state or local level, sampling may not be necessary—many states and localities count all materials recovered for recycling, and many weigh all wastes being disposed to generate state or local recycling rates from the "ground up." To use these figures at the national level would require all states to perform these studies, and perform them in a consistent manner conducive to developing a national summary, which so far has not been practical. Materials flow. The second approach to quantifying and characterizing the municipal solid waste stream-the methodology used for this report-utilizes a materials flow approach to estimate the waste stream on a nationwide basis. In the late 1960s and early 1970s, EPA's Office of Solid Waste and its predecessors at the Public Health Service sponsored work that began to develop this methodology. This report represents the latest version of this database that has been evolving for over 30 years. The materials flow methodology is based on production data (by weight) for the materials and products in the waste stream. To estimate generation data, specific adjustments are made to the production data for each material and product category. Adjustments are made for imports and exports and for diversions from MSW (e.g., for building materials made of plastic and paperboard that become construction and demolition debris.) Adjustments are also made for the lifetimes of products. Finally, food scraps, yard trimmings, and a small amount of miscellaneous inorganic wastes are accounted for by compiling data from a variety of waste sampling studies. One problem with the materials flow methodology is that product residues associated with other items in MSW (usually containers) are not accounted for. These residues would include, for example, food left in a jar, detergent left in a box or bottle, and dried paint in a can. Some household hazardous wastes, (e.g., pesticide left in a can) are also included among these product residues. 25 ------- Chapter 1 Introduction and Methodology Municipal Solid Waste Defined in Greater Detail As stated earlier, EPA includes those materials that historically have been handled in the municipal solid waste stream-those materials from municipal sources, sent to municipal landfills. In this report, MSW includes wastes such as product packaging, newspapers, office and classroom paper, bottles and cans, boxes, wood pallets, food scraps, grass clippings, clothing, furniture, appliances, automobile tires, consumer electronics, and lead-acid batteries. For purposes of analysis, these products and materials are often grouped in this report into the following categories: durable goods, nondurable goods, containers and packaging, food scraps and yard trimmings, and miscellaneous inorganic wastes. Municipal solid wastes characterized in this report come from residential, commercial, institutional, or industrial sources. Some examples of the types of MSW that come from each of the broad categories of sources are: Sources and Examples Residential (single-and multi-family homes) Commercial (office buildings, retail and wholesale establishments, restaurants) Institutional (schools, libraries, hospitals, prisons) Industrial (packaging and administrative; not process wastes) Example Products Newspapers, clothing, disposable tableware, food packaging, cans and bottles, food scraps, yard trimmings Corrugated boxes, food scraps, office papers, disposable tableware, paper napkins, yard trimmings Cafeteria and restroom trash can wastes, office papers, classroom wastes, yard trimmings Corrugated boxes, plastic film, wood pallets, lunchroom wastes, office papers. 26 ------- Chapter 1 Introduction and Methodology The materials flow methodology used in this report does not readily lend itself to the quantification of wastes according to their sources. For example, corrugated boxes may be unpacked and discarded from residences, commercial establishments such as grocery stores and offices, institutions such as schools, or factories. Similarly, office papers are mostly generated in offices, but they also are generated in residences and institutions. The methodology estimates only the total quantity of products generated, not their places of disposal or recovery for recycling. Other Subtitle D Wastes Some people assume that "municipal solid waste" must include everything that is landfilled in Subtitle D landfills. (Subtitle D of the Resource Conservation and Recovery Act deals with wastes other than the hazardous wastes covered under Subtitle C.) As shown in Figure 1-A, however, RCRA Subtitle D includes many kinds of wastes. It has been common practice to landfill wastes such as municipal sludges, nonhazardous industrial wastes, residue from automobile salvage operations, and construction and demolition debris along with MSW, but these other kinds of wastes are not included in the estimates presented in this report. Figure 1-A. Municipal Solid Waste in the Universe of Subtitle D Wastes Subtitle D Wastes The Subtitle D Waste included in this report is Municipal Solid Waste, which includes: Containers and packaging such as soft drink bottles and corrugated boxes Durable goods such as furniture and appliances Nondurable goods such as newspapers, trash bags, and clothing Other wastes such as food scraps and yard trimmings. Subtitle D Wastes not included in this report are: Municipal sludges Agricultural wastes Industrial nonhazardous process wastes Oil and gas wastes Construction and demolition debris Mining wastes Land clearing debris Auto bodies Transportation parts and equipment Fats, grease, and oils 27 ------- Chapter 1 Introduction and Methodology Figure 1-B. Definition of Terms The materials flow methodology produces an estimate of total municipal solid waste generation, recovery, and discards in the United States by materials and by product categories. The term generation as used in this report refers to the weight of materials and products as they enter the waste management system from residential, commercial, institutional, and industrial sources and before materials recovery or combustion takes place. Preconsumer (industrial) scrap is not included in the generation estimates. Source reduction activities (e.g., backyard composting of yard trimmings) take place ahead of generation. Source reduction activities reduce the amount or toxicity of wastes before they enter the municipal solid waste management system. Reuse is a source reduction activity involving the recovery or reapplication of a package, used product, or material in a manner that retains its original form or identity. Reuse of products such as refillable glass bottles, reusable plastic food storage containers, or refurbished wood pallets is considered to be source reduction, not recycling. Recovery of materials as estimated in this report includes products and yard trimmings removed from the waste stream for the purpose of recycling or composting. For recovered products, recovery equals reported purchases of postconsumer recovered material (e.g., glass cullet, old newspapers) plus net exports (if any) of the material. Thus, recovery of old corrugated containers (OCC) is the sum of OCC purchases by paper mills plus net exports of OCC. If recovery as reported by a data source includes converting or fabrication (preconsumer) scrap, the preconsumer scrap is not counted towards the recovery estimates in this report. Imported secondary materials are also not counted in recovery estimates in this report. For some materials, additional uses, such as glass used for highway construction or newspapers used to make insulation, are added into the recovery totals. Combustion of MSW with energy recovery, often called "waste-to-energy," is estimated in Chapter 3 of this report. Combustion of separated materials-wood and rubber from tires-is included in the estimates of combustion with energy recovery in this report. Discards include MSW remaining after recovery for recycling or composting. These discards presumably would be combusted with or without energy recovery or landfilled, although some MSW is littered, stored or disposed onsite, or burned onsite, particularly in rural areas. No good estimates for these other disposal practices are available, but the total amounts of MSW involved are presumed to be small. 28 ------- Chapter 1 Introduction and Methodology For the analysis of municipal solid waste, products are divided into three basic categories: durable goods, nondurable goods, and containers and packaging. The durable goods and nondurable goods categories generally follow the definitions of the U.S. Department of Commerce. Durable goods are those products that last 3 years or more. Products in this category include major and small appliances, furniture and furnishings, carpets and rugs, tires, lead-acid batteries, consumer electronics, and other miscellaneous durables. Nondurable goods are those products that last less than 3 years. Products in this category include newspapers, books, magazines, office papers, directories, mail, other commercial printing, tissue paper and towels, paper and plastic plates and cups, trash bags, disposable diapers, clothing and footwear, towels, sheets and pillowcases, other nonpackaging paper, and other miscellaneous nondurables. Containers and packaging are assumed to be discarded the same year the products they contain are purchased. Products in this category include bottles, containers, corrugated boxes, milk cartons, folding cartons, bags, sacks, and wraps, wood packaging, and other miscellaneous packaging. Materials and Products Not Included in These Estimates As noted earlier, other Subtitle D wastes (illustrated in Figure 1-A) are not included in these estimates, even though some may be managed along with MSW (e.g., by combustion or landfilling). Household hazardous wastes, while generated as MSW with other residential wastes, are not identified separately in this report. Transportation parts and equipment (including automobiles and trucks) are not included in the wastes characterized in this report. Certain other materials associated with products in MSW are often not accounted for because the appropriate data series have not yet been developed. These include, for example, inks and other pigments and some additives associated with packaging materials. Considerable additional research would be required to estimate these materials, which constitute a relatively small percentage of the waste stream. 29 ------- Chapter 1 Introduction and Methodology Some adjustments are made in this report to account for packaging of imported goods, but there is little available documentation of these amounts. OVERVIEW OF THIS REPORT Following this introductory chapter, Chapter 2 presents the results of the municipal solid waste characterization (by weight). Estimates of MSW generation, recovery, and discards are presented in a series of tables, with discussion. Detailed tables and figures summarizing 2009 MSW generation, recovery, and discards of products in each material category are included. In Chapter 3 of the report, estimates of MSW management by the various alternatives are summarized. These include recovery for recycling and composting, combustion, and landfilling. Summaries of the infrastructure currently available for each waste management alternative are also included in Chapter 3. A brief discussion of the materials flow methodology for estimating generation, recycling, and disposal is presented in Appendix A. 30 ------- Chapter 1 Introduction and Methodology CHAPTER 1 REFERENCES Darnay, A., and W.E.

The data presented also incorporate some revisions to previously reported data for 1990 through 2008. The revisions are generally due to improvements in the data available from data sources used in developing this report. This chapter discusses how much municipal solid waste (MSW) is generated, recovered, and disposed. First, an overview presents this information for the most recent years, and for selected years back to 1960. This information is summarized in Tables 1 to 3 and Figures 10 to 13. Then, throughout the remainder of the chapter, MSW is characterized in more detail. Findings are presented in two basic ways: the first portion of the chapter presents data by material type. Some material types of most use to planners (paper and paperboard, glass, metals, plastics, and rubber and leather) are presented in detail in Tables 4 to 8 and Figures 2 to 9, while data on other materials also are summarized in Figures 12 and 13. The second portion of the chapter presents data byproduct type. This information is presented in Tables 9 to 23 and Figures 14 to 16. Products are classified into durable goods (e.g., appliances, furniture, tires); nondurable goods (e.g., newspapers, office-type papers, trash bags, clothing); and containers and packaging (e.g., bottles, cans, corrugated boxes). A fourth major category includes other wastes—yard trimmings, food scraps, and miscellaneous inorganic wastes. These wastes are not manufactured products, but to provide complete information in each table, they are included in both the product and the material tables. 34 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight This chapter provides data on generation, recovery, and discards of MSW. (See Figure 1- B in Chapter 1 for definitions of these terms.) Recovery, in this report, means that the materials have been removed from the municipal solid waste stream. Recovery of materials in products means that the materials are reported to have been purchased by an end user or have been exported from the United States. For yard trimmings and food scraps, recovery includes estimates of the material delivered to a composting facility (not backyard composting). Under these definitions, residues from a materials recovery facility (MRF) or other waste processing facility are counted as generation (and, of course, discards), since they are not purchased by an end user. Residues from an end user facility (e.g., sludges from a paper deinking mill) are considered to be industrial process wastes that are no longer part of the municipal solid waste stream. MUNICIPAL SOLID WASTE: CHARACTERIZED BY MATERIAL TYPE Generation, recovery, and discards of materials in MSW, by weight and by percentage of generation and discards, are summarized in Tables 1 through 3. Figures 10 and 11 (later in this chapter) illustrate these data over time. A snapshot, by material, for 2009 is provided in Figures 12 and 13. In the following sections, each material is discussed in detail. 35 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Table 1 MATERIALS GENERATED* IN THE MUNICIPAL WASTE STREAM, 1960 TO 2009 (In thousands of tons and percent of total generation) Materials Paper and Paperboard Glass Metals Ferrous Aluminum Other Nonferrous Total Metals Plastics Rubber and Leather Textiles Wood Other ** Total Materials in Products Other Wastes Food Scraps Yard Trimmings Miscellaneous Inorganic Wastes Total Other Wastes Total MSW Generated - Weight Materials Paper and Paperboard Glass Metals Ferrous Aluminum Other Nonferrous Total Metals Plastics Rubber and Leather Textiles Wood Other ** Total Materials in Products Other Wastes Food Scraps Yard Trimmings Miscellaneous Inorganic Wastes Total Other Wastes Total MSW Generated - % Thousands of Tons 1960 29,990 6,720 10,300 340 180 10,820 390 1,840 1,760 3,030 70 54,620 12,200 20,000 1,300 33,500 88,120 1970 44,310 12,740 12,360 800 670 13,830 2,900 2,970 2,040 3,720 770 83,280 12,800 23,200 1,780 37,780 121,060 1980 55,160 15,130 12,620 1,730 1,160 15,510 6,830 4,200 2,530 7,010 2,520 108,890 13,000 27,500 2,250 42,750 151,640 1990 72,730 13,100 12,640 2,810 1,100 16,550 17,130 5,790 5,810 12,210 3,190 146,510 23,860 35,000 2,900 61,760 208,270 2000 87,740 12,760 14,110 3,200 1,600 18,910 25,540 6,710 9,440 13,600 4,000 178,700 29,810 30,530 3,500 63,840 242,540 2005 84,840 12,540 14,990 3,330 1,860 20, 180 29,260 7,360 11,380 14,790 4,280 184,630 31,990 32,070 3,690 67,750 252,380 2007 82,530 12,520 15,640 3,360 1,880 20,880 30,750 7,540 1 1 ,940 15,280 4,550 185,990 32,610 32,630 3,750 68,990 254,980 2008 77,420 12,150 15,730 3,410 1,960 21,100 30,060 7,630 12,430 15,540 4,670 181,000 33,340 32,900 3,780 70,020 251,020 2009 68,430 11,780 15,620 3,400 1,890 20,910 29,830 7,490 12,730 15,840 4,640 171,650 34,290 33,200 3,820 71,310 242,960 Percent of Total Generation 1960 34.0% 7.6% 11.7% 0.4% 0.2% 12.3% 0.4% 2.1% 2.0% 3.4% 0.1% 62.0% 1 3.8% 22.7% 1 .5% 38.0% 100.0% 1970 36.6% 10.5% 10.2% 0.7% 0.6% 11.4% 2.4% 2.5% 1 .7% 3.1% 0.6% 68.8% 10.6% 19.2% 1 .5% 31 .2% 100.0% 1980 36.4% 10.0% 8.3% 1.1% 0.8% 10.2% 4.5% 2.8% 1.7% 4.6% 1.7% 71.8% 8.6% 18.1% 1.5% 28.2% 100.0% 1990 34.9% 6.3% 6.1% 1.3% 0.5% 7.9% 8.2% 2.8% 2.8% 5.9% 1 .5% 70.3% 1 1 .5% 16.8% 1 .4% 29.7% 100.0% 2000 36.2% 5.3% 5.8% 1 .3% 0.7% 7.8% 10.5% 2.8% 3.9% 5.6% 1 .6% 73.7% 12.3% 12.6% 1 .4% 26.3% 100.0% 2005 33.6% 5.0% 5.9% 1.3% 0.7% 8.0% 1 1 .6% 2.9% 4.5% 5.9% 1.7% 73.2% 12.7% 12.7% 1 .5% 26.8% 100.0% 2007 32.4% 4.9% 6.1% 1.3% 0.7% 8.2% 12.1% 3.0% 4.7% 6.0% 1 .8% 72.9% 12.8% 12.8% 1 .5% 27.1% 100.0% 2008 30.8% 4.8% 6.3% 1 .4% 0.8% 8.4% 12.0% 3.0% 5.0% 6.2% 1 .9% 72.1% 13.3% 13.1% 1 .5% 27.9% 100.0% 2009 28.2% 4.8% 6.4% 1 .4% 0.8% 8.6% 12.3% 3.1% 5.2% 6.5% 1 .9% 70.6% 14.1% 13.7% 1 .6% 29.4% 100.0% Generation before materials recovery or combustion.

Figure 3. Paper and paperboard generation and recovery, 1960 to 2009 1960 1965 1970 1975 1980 1985 1990 1995 2000 2005 The sensitivity of paper products to economic conditions can be observed in Figure 3. The tonnage of paper generated in 1975—a severe recession year—was actually less than the tonnage in 1970. Similar but less pronounced declines in paper generation can be seen in other recession years. This sensitivity is most obvious after 2006. The wide variety of products that comprise the paper and paperboard materials total is illustrated in Table 4 and Figure 2. In this report, these products are classified as nondurable goods or as containers and packaging, with nondurable goods being the larger category. 41 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Generation. Estimates of paper and paperboard generation are based on statistics published by the American Forest & Paper Association (AF&PA). These statistics include data on new supply (production plus net imports) of the various paper and paperboard grades that go into the products found in MSW. The AF&PA new supply statistics are adjusted to deduct converting scrap, which is generated when sheets or rolls of paper or paperboard are cut to make products such as envelopes or boxes. Converting scrap rates vary from product to product; the rates used in this report were developed as part of a 1992 report for the Recycling Advisory Council, with a few more revisions as new data became available. Various deductions also are made to account for products diverted out of municipal solid waste, such as gypsum wallboard facings (classified as construction and demolition debris) or toilet tissue (which goes to wastewater treatment plants). Recovery. Estimates of recovery of paper and paperboard products for recycling are based on annual reports of recovery published by AF&PA. The AF&PA reports include recovery of paper and paperboard purchased by U.S. paper mills, plus exports of recovered paper, plus a relatively small amount estimated to have been used in other products such as insulation and animal bedding. Recovery as reported by AF&PA includes both preconsumer and postconsumer paper. To estimate recovery of postconsumer paper products for this EPA report, estimates of recovery of converting scrap (preconsumer industrial process waste) are deducted from the total recovery amounts reported by AF&PA. In earlier versions of this EPA report, a simplifying assumption that all converting scrap is recovered was made. For more recent updates, various converting scrap recovery rates ranging from 70 percent to 98 percent were applied to the estimates for 1990 through 2009. The converting scrap recovery rates were developed for a 1992 report for the Recycling Advisory Council. Because recovered converting scrap is deducted, the paper recovery rates presented in this report are always lower than the total recovery rates published by AF&PA. 42 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight When recovered paper is repulped, and often deinked, at a recycling paper mill, considerable amounts of sludge are generated in amounts varying from 5 percent to 35 percent of the paper feedstock. Since these sludges are generated at an industrial site, they are considered to be industrial process waste, not municipal solid waste; therefore they have been removed from the municipal waste stream. Recovery of paper and paperboard for recycling is among the highest rates overall compared to other materials in MSW (Table 2). As Table 4 shows, 81.3 percent of all corrugated boxes were recovered for recycling in 2009; this is up from 67.3 percent in 2000 (Table 21). Newspapers were recovered at a rate of 88.1 percent, and high grade office papers at 74.2 percent, with lesser percentages of other papers being recovered also. Approximately 43 million tons of postconsumer paper were recovered in 2009—62.1 percent of total paper and paperboard generation. This is up from 42.8 percent in 2000 (Table 2). Discards After Recovery. After recovery of paper and paperboard for recycling, discards were 25.9 million tons in 2009, or 16.1 percent of total MSW discards (Table 3). Glass Glass is found in MSW primarily in the form of containers (Table 5 and Figures 4 and 5), but also in durable goods like furniture, appliances, and consumer electronics. In the container category, glass is found in beer and soft drink bottles, wine and liquor bottles, and bottles and jars for food, cosmetics, and other products. More detail on these products is included in the later section on products in MSW. 43 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Table 5 GLASS PRODUCTS IN MSW, 2009 (In thousands of tons and percent of generation) Product Category Durable Goods* Containers and Packaging Beer and Soft Drink Bottles** Wine and Liquor Bottles Other Bottles and Jars Total Glass Containers Total Glass Generation (Thousand tons) 2,120 6,000 1,710 1,950 9,660 11,780 Recovery (Thousand tons) Neg. 2,340 310 350 3,000 3,000 (Percent of generation) Neg. 39.0% 18.1% 17.9% 31.1% 25.5% Discards (Thousand tons) 2,120 3,660 1,400 1,600 6,660 8,780 Glass as a component of appliances, furniture, consumer electronics, etc. ** Includes carbonated drinks and non-carbonated water, teas, flavored drinks, and ready-to-drink alcoholic coolers and cocktails.

Glass accounted for 6.7 million tons of MSW in 1960, or 7.6 percent of total generation. Generation of glass continued to grow over the next two decades, but then glass containers were widely displaced by other materials, principally aluminum and plastics. Thus the tonnage of glass in MSW declined in the 1980s, from approximately 15.1 million tons in 1980 to 13.1 million tons in 1990. Beginning about 1987, however, the decline in generation of glass containers slowed (Figure 5). During the 1990s glass generation varied from 12.0 to 13.6 million tons per year. After 2000, glass generation trended downward from 12.8 to 11.8 million tons in 2009. Glass was 10 percent of MSW generation in 1980, declining to 4.8 percent in 2009. 18 16 Figure 5.

Recovered glass containers (bottles) are used to make new glass containers and other uses such as fiberglass insulation, aggregate, and glasphalt for road construction. Until 1998, the Glass Packaging Institute published estimates of glass bottle recovery annually. Since this data source is no longer available, industry and state agency sources were contacted for recovery data. Recovery of glass containers was estimated at 3.0 million tons in 2009, up from an estimated 2.8 million tons in 2008. Discards After Recovery. Recovery for recycling lowered discards of glass to 8.8 million tons in 2009 or 5.5 percent of total MSW discards (Table 3). Ferrous Metals By weight, ferrous metals (iron and steel) are the largest category of metals in MSW (Table 6 and Figure 6). The largest quantities of ferrous metals in MSW are found in durable goods such as appliances, furniture, and tires. Containers and packaging are the other source of ferrous metals in MSW. Large quantities of ferrous metals are found in construction materials and in transportation parts and products such as automobiles, locomotives, and ships, but these are not counted as MSW in this report. Total generation and recovery of all metals in MSW from 1960 to 2009 are shown in Figure 7. Generation. Approximately 10.3 million tons of ferrous metals were generated in 1960. Like glass, the tonnages grew during the 1960s, but began to slow as lighter materials like aluminum and plastics replaced steel in many applications. Since 1970, generation of ferrous metals has varied between about 12.4 million tons in 1970 to 15.6 million tons in 2009 (Table 1). The percentage of ferrous metals generation in total MSW has declined from 11.7 percent in 1960 to 6.4 percent in 2009. 46 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Table 6 METAL PRODUCTS IN MSW, 2009 (In thousands of tons and percent of generation) Product Category Durable Goods Ferrous Metals* Aluminum** Leadt Other Nonferrous Metals $ Total Metals in Durable Goods Nondurable Goods Aluminum Containers and Packaging Steel Cans Other Steel Packaging Total Steel Packaging Aluminum Beer and Soft Drink Cans Other Cans Foil and Closures Total Aluminum Packaging Total Metals in Containers and Packaging Total Metals Ferrous Aluminum Other nonferrous Generation (Thousand tons) 13,340 1,350 1,350 540 16,580 210 1,940 340 2,280 1,360 70 410 1,840 4,120 20,910 15,620 3,400 1,890 Recovery (Thousand tons) 3,720 Neg. 1,300 Neg. 5,020 Neg. 1,280 230 1,510 690 NA NA 690 2,200 7,220 5,230 690 1,300 (Percent of generation) 27.9% Neg. 96.3% Neg. 30.3% Neg. 66.0% 67.6% 66.2% 50.7% 37.5% 53.4% 34.5% 33.5% 20.3% 68.8% Discards (Thousand tons) 9,620 1,350 50 540 11,560 210 660 110 770 670 70 410 1,150 1,920 13,690 10,390 2,710 590 Ferrous metals (iron and steel) in appliances, furniture, tires, and miscellaneous durables.

The renewed emphasis on recovery and recycling in recent years has included ferrous metals. Based on data from the Steel Recycling Institute, recovery of ferrous metals from appliances ("white goods") was estimated at a rate of 90 percent in 2009. Recovery of all materials in appliances (including ferrous metals) was estimated at 66.8 percent (Table 13). Overall recovery of ferrous metals from durable goods (large and small appliances, furniture, and tires) was estimated to be 27.9 percent (3.7 million tons) in 2009 (Table 6). Steel cans were estimated to be recovered at a rate of 66.0 percent (1.3 million tons) in 2009. Approximately 230,000 tons of other steel packaging, including strapping, crowns, and drums, were estimated to have been recovered for recycling in 2008. Recovery of ferrous metals includes material collected through recycling programs as well as metal recovered at combustion facilities. Discards After Recovery. In 2009, discards of ferrous metals after recovery were 10.4 million tons, or 6.5 percent of total discards (Table 3). Aluminum The largest source of aluminum in MSW is aluminum cans and other packaging (Table 6 and Figure 6). Other sources of aluminum are found in durable and nondurable goods. Generation. In 2009, 1.8 million tons of aluminum were generated as containers and packaging, while approximately 1.6 million tons were found in durable and nondurable goods. The total-3.4 million tons-was 1.4 percent of total MSW generation in 2009 (Table 1). Aluminum generation was only 340,000 tons (0.4 percent of MSW generation) in 1960. Recovery. Aluminum beverage containers were recovered at a rate of 50.7 percent of generation (0.7 million tons) in 2009, and 37.5 percent of all aluminum in containers and packaging (beverage containers, food containers, foil, and other aluminum packaging) was recovered for recycling in 2009. 49 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Discards After Recovery. In 2009, about 2.7 million tons of aluminum were discarded in MSW after recovery, which was 1.7 percent of total MSW discards (Table 3). Other Nonferrous Metals Other nonferrous metals (e.g., lead, copper, zinc) are found in durable products such as appliances, consumer electronics, etc. Lead in lead-acid batteries is the most prevalent nonferrous metal (other than aluminum) in MSW. Note that only lead-acid batteries from passenger cars, trucks, and motorcycles are included. Lead-acid batteries used in large equipment or industrial applications are not included. Generation. Generation of other nonferrous metals in MSW totaled 1.9 million tons in 2009. Lead in batteries accounted for 1.4 million tons of this amount. Generation of these metals has increased slowly, up from 180,000 tons in 1960, 1.1 million tons in 1990, and 1.6 million tons in 2000. As a percentage of total generation, nonferrous metals have never exceeded one percent. Recovery. Recovery of the other nonferrous metals was 1.3 million tons in 2009, with most of this being lead recovered from batteries. It was estimated about 96 percent of battery lead was recovered in 2009. Discards After Recovery. In 2009, 590,000 tons of nonferrous metals were discarded in MSW. Percentages of total discards remained less than one percent over the entire period. Plastics Plastics are a rapidly growing segment of MSW. While plastics are found in all major MSW categories, the containers and packaging category (bags, sacks, and wraps, other packaging, PET bottles, jars and HDPE natural bottles, and other containers) has the most plastic tonnage at 12.5 million tons in 2009 (Figure 8 and Table 7). 50 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Figure 8.

(Note that plastics in transportation products other than lead-acid batteries are not included in this report.) As shown in Table 7, a wide range of resin types is found in durable goods. While some detail is provided in Table 7 for resins in durable goods, there are hundreds of different resin formulations used in appliances, carpets, and other durable goods; a complete listing is beyond the scope of this report. 51 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Table 7 PLASTICS IN PRODUCTS IN MSW, 2009 (In thousands of tons, and percent of generation by resin) Product Category Durable Goods PET HOPE PVC LDPE/LLDPE PP PS Other resins Total Plastics in Durable Goods Nondurable Goods Plastic Plates and Cups LDPE/LLDPE PP PS Subtotal Plastic Plates and Cups Trash Bags HOPE LDPE/LLDPE Subtotal Trash Bags All other nondurables* PET HOPE PVC LDPE/LLDPE PP PS Other resins Subtotal All Other Nondurables Total Plastics in Nondurable Goods, by resin PET HOPE PVC LDPE/LLDPE PP PS Other resins Total Plastics in Nondurable Goods Plastic Containers & Packaging Bottles and Jars** PET Natural Bottlesf HOPE Generation (Thousand tons) 410 1,190 360 900 2,630 710 4,450 10,650 20 170 710 900 230 770 1,000 400 410 330 1,390 890 580 750 4,750 400 640 330 2,180 1,060 1,290 750 6,650 2,570 760 Recovery (Thousand tons) (Percent of Gen.)

Source: Franklin Associates, A Division of ERG 53 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Plastics are found in such nondurable products as disposable diapers, trash bags, cups, eating utensils, medical devices, and household items such as shower curtains. The plastic food service items are generally made of clear or foamed polystyrene, while trash bags are made of high-density polyethylene (HDPE) or low-density polyethylene (LDPE). A wide variety of other resins are used in other nondurable goods. Plastic resins are also used in a variety of container and packaging products such as polyethylene terephthalate (PET) beverage bottles, high-density polyethylene (HDPE) bottles for milk and water, and a wide variety of other resin types used in other plastic containers, bags, sacks, wraps, and lids. Generation. Production data on plastics resin use in products are taken from the American Chemistry Council's annual resin reports. The basic data are adjusted for product service life, fabrication losses, and net imports of plastic products to derive generation of plastics in the various products in MSW. Plastics made up an estimated 390,000 tons of MSW generation in 1960. The quantity has increased relatively steadily to 29.8 million tons in 2009 (Figure 9). As a percentage of MSW generation, plastics were less than one percent in 1960, increasing to 12.3 percent in 2009. Recovery for Recycling. While overall recovery of plastics for recycling is relatively small - 2.1 million tons, or 7.1 percent of plastics generation in 2009 (Table 7) - recovery of some plastic containers is more significant. PET bottles and jars were recovered at a rate of 28.0 percent in 2009. Recovery of high-density polyethylene natural bottles was estimated at 28.9 percent in 2009. Significant recovery of plastics from polypropylene lead-acid battery casings and from some other containers was also reported. The primary sources of data on plastics recovery are annual product recovery surveys conducted for the American Chemistry Council and the National Association for PET Container Resources (NAPCOR). 54 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Discards After Recovery. Discards of plastics in MSW after recovery were 27.7 million tons, or 17.2 percent of total MSW discards in 2009 (Table 3). Figure 9. Plastics generation and recovery, 1960 to 2009 1960 1965 1970 1975 1980 1985 1990 1995 2000 2005 Other Materials Rubber and Leather. The predominant source of rubber in MSW is rubber tires from automobiles and trucks (Table 8). Other sources of rubber and leather include clothing and footwear and other miscellaneous durable and nondurable products. These other sources are quite diverse, including such items as gaskets on appliances, furniture, and hot water bottles, for example. 55 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Generation. Generation of rubber and leather in MSW has shown slow growth over the years, increasing from 1.8 million tons in 1960 to 7.5 million tons in 2009. One reason for the relatively slow rate of growth is that tires have been made smaller and longer-wearing than in earlier years. As a percentage of total MSW generation, rubber and leather has been about 3 percent for many years. Recovery for Recycling. The only recovery for recycling identified in this category is rubber from tires, and that was estimated to be 1.1 million tons in 2009. This is 35.2 percent of rubber in tires in 2009 (Table 8). (This recovery estimate does not include tires retreaded or energy recovery from tires.) Overall, 14.3 percent of rubber and leather in MSW was recovered in 2009.

Source: Franklin Associates, A Division of ERG 56 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Discards After Recovery. Discards of rubber and leather after recovery were 6.4 million tons in 2009 (4.0 percent of total discards). Textiles. Textiles in MSW are found mainly in discarded clothing, although other sources were identified to be furniture, carpets, tires, footwear, and other nondurable goods such as sheets and towels. Generation. An estimated 12.7 million tons of textiles were generated in 2009 or 5.2 percent of total MSW generation (Table 1). Significant amounts of textiles enter the reuse market. However, the reused garments and wiper rags re-enter the waste stream eventually becoming part of MSW generation. Since reuse occurs prior to generation, the amount of reused textiles is not included in the generation estimates (or estimated separately). Recovery for Recycling and Discards. It was estimated that 13.8 percent of textiles in clothing and footwear and 17.1 percent of items such as sheets and pillowcases was recovered for export or reprocessing in 2009 (1.4 million tons) (Table 16). The recovery rate for all textiles is 14.9 percent in 2009 (1.9 million tons) (Table 2). Wood. The sources of wood in MSW include furniture, other durable goods (e.g., cabinets for electronic equipment), wood packaging (crates, pallets), and some other miscellaneous products. Generation and recovery methodologies for wood pallets are based on data from the Center for Forest Products Marketing and Management (Virginia Polytechnic Institute). Generation. Generation of wood in MSW was 15.8 million tons in 2009 (6.5 percent of total MSW generation). Recovery for Recycling and Discards. Wood pallet recovery for recycling (usually by chipping for uses such as mulch or bedding material, but excluding wood combusted as fuel) was estimated at 2.2 million tons in 2009. 57 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Accounting for recovery for recycling, wood discards were 13.6 million tons in 2009, or 8.5 percent of total MSW discards (Table 3). Other Materials. Generation of "other materials" waste is mainly associated with disposable diapers, which are discussed under Products in Municipal Solid Waste. The only other significant sources of materials in this category are the electrolytes and other materials associated with lead-acid batteries that are not classified as plastics or nonferrous metal. Food Scraps Food scraps included here consist of uneaten food and food preparation wastes from residences, commercial establishments such as grocery stores and sit-down and fast food restaurants, institutional sources such as school cafeterias, and industrial sources such as factory lunchrooms. Preconsumer food waste generated during the manufacturing and packaging of food products is considered industrial waste and therefore not included in MSW food scrap estimates. Generation. No production data are available for food scraps. Food scraps from residential and commercial sources were estimated using data from sampling studies in various parts of the country in combination with demographic data on population, grocery store sales, restaurant sales, numbers of employees, and numbers of prisoners, students, and patients in institutions. Generation of food scraps was estimated to be 34.3 million tons in 2009 (14.1 percent of total generation) (Table 1). Food scrap generation has increased, from earlier versions of this report, due to increased population and revised commercial sampling study data. Significant amounts of food products are donated by residents and commercial establishments (such as grocery stores and restaurants) to local food banks and charities. A good portion of these food donations (in particular, the commercial establishment donations of wholesome but not-for-retail food products) represents waste diversion by removing food scraps that would otherwise need to be managed either through composting or disposal. Data on these types of programs are limited. For example, Portland, Oregon reported 14,000 tons of food 58 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight products diverted from the commercial sector through donations. This diversion takes place prior to generation and therefore is not included in the generation estimates presented in this report. Recovery for Composting and Discards. Beginning in 1994 for this series of reports, a significant amount of food scraps composting from commercial sources was identified. As the data source (a survey published by BioCycle magazine) improved, it became apparent that some other composted materials (e.g., industrial food processing wastes) had been included with food scraps classified as MSW in the past. Beginning in 2004, BioCycle staff conducted more targeted data gathering of MSW food waste composting from primary sources including state solid waste officials, large-scale municipal and commercial composting facilities, and large generators (e.g., supermarkets and restaurants). The targeted data gathering of MSW food scrap composting operations resulted in an estimate of 560,000 tons food scraps composted in 2009 (an increase of 100,000 tons from 2008). A separate BioCycle publication estimated 290,000 tons of MSW composted in 2009 (a decrease of 50,000 tons from 2008). MSW composting includes the composting of food scraps as well as other organic materials found in MSW. The total - 850,000 tons of food scraps and other organic materials composted in 2009 - is shown in the recovery tables. Yard Trimmings Yard trimmings2 include grass, leaves, and tree and brush trimmings from residential, institutional, and commercial sources. Generation. In earlier versions of this report, generation of yard trimmings was estimated using sampling studies and population data. While in past years generation of yard trimmings had been increasing steadily as population and residential housing grew (i.e., constant generation on a per capita basis), in the 1990s local and state governments started enacting legislation that discouraged yard trimmings disposal in landfills. 2 Although limited data are available on the composition of yard trimmings, it is estimated that the average composition by weight is about 50 percent grass, 25 percent brush, and 25 percent leaves. These are "ballpark" numbers that will vary widely according to climate and region of the country. 59 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Legislation affecting yard trimmings disposal in landfills was tabulated, using published sources. In 1992, 11 states and the District of Columbia-accounting for more than 28 percent of the nation's population-had legislation in effect that bans or discourages yard trimmings disposal in landfills. The tabulation of current legislation shows 23 states-representing about 50 percent of the nation's population have legislation affecting disposal of yard trimmings. In addition, some local and regional jurisdictions regulate disposal of yard trimmings. This has led to an increase in backyard composting and the use of mulching mowers to allow grass trimmings to remain in place since the early 1990's. However, we are unable to estimate the influence of backyard composting and use of mulching mowers on a yearly basis. Using these facts, it was estimated that yard trimmings generation has declined since 1990. In the absence of significant new legislation, yard trimmings generation has been increasing slightly since 2000 (i.e., increasing as natural population and residential dwelling units increase). An estimated 33.2 million tons of yard trimmings were generated in MSW in 2009. Recovery for Composting and Discards. Recovery for composting of yard trimmings was estimated using information from state composting programs that estimated tonnages composted or mulched in 2009. State reported composting tonnages may vary on a yearly basis with the amount of storm debris composted. Analysis of this information resulted in an estimate of 19.9 million tons of yard trimmings removed for composting or wood waste mulching in 2009 - a significant increase over the 2000 estimate of 15.8 million tons. It should be noted that the estimated 19.9 million tons recovered for composting in 2009 does not include yard trimmings recovered for direct landspreading disposal. It also should be noted that these recovery estimates do not account for backyard composting by individuals and practices such as less bagging of grass clippings. These are source reduction activities taking place onsite, while the yard trimmings recovery estimates are based on material sent off-site. 60 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Miscellaneous Inorganic Wastes This relatively small category of MSW is derived from sampling studies. It is not well defined and often shows up in sampling reports as "fines" or "other." It includes soil, bits of concrete, stones, and the like. Generation, Recovery, and Discards. This category contributed an estimated 3.8 million tons of MSW in 2009. No recovery of these products was identified; discards are the same as generation. Summary of Materials in Municipal Solid Waste Generation. Changing quantities and composition of municipal solid waste generation are illustrated in Figure 10. Generation of MSW has grown relatively steadily, from 88.1 million tons in 1960 to 243.0 million tons in 2009. Over the years paper and paperboard has been the dominant material category generated in MSW, accounting for 68 million tons (28.2 percent of generation) in 2009. Food scraps, the second largest material component of MSW at 34.3 million tons (14.1 percent of MSW generation) have increased in terms of MSW tonnage and percentage of total MSW. Yard trimmings, the third largest material component of MSW at 33.2 million tons (13.7 percent of generation) has declined as a percentage of MSW since 1990 due to state and local legislated landfill disposal restrictions and increased emphasis on backyard composting and other source reduction measures such as the use of mulching mowers. 61 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Metals account for 20.9 million tons (8.6 percent of MSW generation) and have remained fairly constant as a source of MSW since 2000. Glass increased until the 1980s; decreasing in tonnage and as a percent of MSW generation since the 1990s. Glass generation was 11.8 million tons in 2009, 4.8 percent of generation. Plastics have increasingly been used in a variety of products and thus have been a rapidly growing component of MSW. In terms of tonnage contributed they ranked fourth in 2009 (behind paper, food scraps, and yard trimmings) at 29.8 million tons, and account for 12.3 percent of MSW generation. Figure 10.

The effect of recovery on MSW discards is illustrated in Figure 11. Recovery of materials for recycling and composting grew at a rather slow pace from 1960 to the 1980s, increasing only from 5.6 million tons (6.4 percent of generation) in 1960 to 14.5 million tons (9.6 percent) in 1980. Renewed interest in recycling (including composting) as waste management alternatives came about in the late 1980s, and the recovery rate in 1990 was estimated to be 16.0 percent of generation (33.2 million tons), increasing to 69.5 million tons (28.6 percent) in 2000, and 82 million tons (33.8 percent of generation) in 2009.

In 2009, recovery of paper and paperboard dominated materials recovery at 51 percent of total tonnage recovered, while yard trimmings contributed 24 percent of total recovery. Recovery of other materials, while generally increasing, contributes much less tonnage, reflecting in part the relatively smaller amounts of materials generated in those categories. 63 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Figure 12.

For example, paper and paperboard products were 28.2 percent of MSW generated in 2009, but after recovery, paper and paperboard products were 16.1 percent of discards. Materials that have less recovery exhibit a larger percentage of MSW discards compared to generation. For example, plastic products were 12.3 percent of MSW generated in 2009 and, after recovery, were 17.2 percent of discards. 64 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Figure 13.

It described how the 243 million tons of MSW were generated, recycled (including composted) and disposed of. The following section breaks out the same 243 million tons of MSW by product. PRODUCTS IN MUNICIPAL SOLID WASTE The purpose of this section is to show how the products that make up municipal solid waste are generated, recycled (including composted) and discarded. For the analysis, products are divided into three basic categories: durable goods, nondurable goods, and containers and packaging. These three categories generally follow the definitions of the U.S. Department of Commerce, one of EPA's data sources. By these definitions, durable goods, (e.g., appliances) are those that last 3 years or more, while nondurable goods (e.g., newspapers and trash bags) last less than 3 years. For this report, containers and packaging are assumed to be discarded the same year the products they contain are purchased. The following 15 tables (Tables 9 through 23) show generation, recycling (including composting) and discards of municipal solid waste in the three categories-durable goods, nondurable goods, and containers and packaging. Within these three categories, products are listed by type - for instance, carpets and rugs, office paper, or aluminum cans. The material the product is made of may be stated as well (for instance, glass beverage containers or steel cans), or may be obvious (for instance, magazines are made of paper.) Some products, such as tires and appliances, are made of several different material types. At the bottom of each of these 15 tables (Tables 9 through 23) there is a section titled "Other Wastes." This contains information on food scraps, yard trimmings, and miscellaneous inorganic wastes. These wastes are not products that can be estimated through the materials flow methodology, but they are estimated by other means, as described earlier. 66 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Within Tables 9 through 23, the first three tables - Tables 9 through 11 - serve as an index to the other tables. Table 9 shows what tables to consult for detailed information on generation; Table 10 shows what tables to consult for detailed information on recovery; and Table 11 does the same for detailed information on discards. The tables on generation all have the same "bottom line" - 242.96 million tons in 2009 - with detail provided in different categories - durable goods, nondurable goods, or containers and packaging. For Table 10 and related tables, the "bottom line" is MSW is recovered - 82.02 million tons; and for Table 11 and related tables, the "bottom line" is MSW discarded - 160.94 million tons. The "bottom line" for each of the quantity tables is calculated by adding the major category subtotal lines. Durable Goods Durable goods generally are defined as products having a lifetime of three years or more, although there are some exceptions. In this report, durable goods include large and small appliances, furniture and furnishings, carpets and rugs, rubber tires, lead-acid automotive batteries, consumer electronics, and other miscellaneous durable goods (e.g., luggage, sporting goods, miscellaneous household goods) (see Tables 12 through 14). These products are often called "oversize and bulky" in municipal solid waste management practice and they are generally handled in a somewhat different manner than other components of MSW. That is, they are often picked up separately, and may not be mixed with other MSW at the landfill, combustor, or other waste management facility. Durable goods are made up of a wide variety of materials. In order of tonnage in MSW in 2009, these include: ferrous metals, plastics, rubber and leather, wood, textiles, glass, other nonferrous metals (e.g., lead, copper), and aluminum. Generation of durable goods in MSW totaled 46.6 million tons in 2009 (19.2 percent of total MSW generation). After recovery for recycling, 38.5 million tons of durable goods remained as discards in 2009. 67 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Table 9 CATEGORIES OF PRODUCTS GENERATED* IN THE MUNICIPAL WASTE STREAM, 1960 TO 2009 (In thousands of tons and percent of total generation) Products Durable Goods (Detail in Table 12) Nondurable Goods (Detail in Table 15) Containers and Packaging (Detail in Table 18) Total Product** Wastes Other Wastes Food Scraps Yard Trimmings Miscellaneous Inorganic Wastes Total Other Wastes Total MSW Generated - Weight Products Durable Goods (Detail in Table 12) Nondurable Goods (Detail in Table 15) Containers and Packaging (Detail in Table 19) Total Product** Wastes Other Wastes Food Scraps Yard Trimmings Miscellaneous Inorganic Wastes Total Other Wastes Total MSW Generated - % Thousands of Tons 1960 9,920 17,330 27,370 54,620 12,200 20,000 1,300 33,500 88,120 1970 14,660 25,060 43,560 83,280 1 2,800 23,200 1,780 37,780 1 21 ,060 1980 21 ,800 34,420 52,670 108,890 13,000 27,500 2,250 42,750 1 51 ,640 1990 29,810 52,170 64,530 146,510 23,860 35,000 2,900 61 ,760 208,270 2000 38,850 64,010 75,840 178,700 29,810 30,530 3,500 63,840 242,540 2005 44,650 63,650 76,330 184,630 31 ,990 32,070 3,690 67,750 252,380 2007 45,770 61 ,760 78,460 185,990 32,610 32,630 3,750 68,990 254,980 2008 46,400 58,690 75,910 181,000 33,340 32,900 3,780 70,020 251 ,020 2009 46,640 53,440 71,570 171,650 34,290 33,200 3,820 71,310 242,960 Percent of Total Generation 1960 1 1 .3% 19.7% 31.1% 62.0% 13.8% 22.7% 1 .5% 38.0% 100.0% 1970 12.1% 20.7% 36.0% 68.8% 10.6% 19.2% 1 .5% 31 .2% 100.0% 1980 14.4% 22.7% 34.7% 71 .8% 8.6% 18.1% 1 .5% 28.2% 100.0% 1990 14.3% 25.0% 31 .0% 70.3% 1 1 .5% 16.8% 1 .4% 29.7% 100.0% 2000 16.0% 26.4% 31 .3% 73.7% 1 2.3% 1 2.6% 1 .4% 26.3% 100.0% 2005 17.7% 25.2% 30.2% 73.2% 1 2.7% 1 2.7% 1 .5% 26.8% 100.0% 2007 18.0% 24.2% 30.8% 72.9% 1 2.8% 1 2.8% 1 .5% 27.1% 100.0% 2008 18.5% 23.4% 30.2% 72.1% 13.3% 13.1% 1 .5% 27.9% 100.0% 2009 19.2% 22.0% 29.5% 70.6% 14.1% 13.7% 1 .6% 29.4% 100.0% Generation before materials recovery or combustion.

Major appliances in MSW include refrigerators, washing machines, water heaters, etc. They are often called "white goods" in the trade. Data on unit production of appliances are taken from Appliance Manufacturer Market Profile, Appliance Manufacturer Shipments Forecasts, and Appliance Statistical Review. The unit data are converted to weight using various conversion factors developed over the years, plus data on the materials composition of the appliances. Adjustments are also made for the estimated lifetimes of the appliances, which range up to 25 years. Generation of major appliances has increased very slowly over the years. In 2009, generation was 3.8 million tons, or 1.5 percent of total MSW generation. In general, the number of units of appliances has increased but average weight per unit has decreased over the years. Ferrous metals (steel and iron) are the predominant materials in major appliances, but other metals, plastics, glass, and other materials are also present. Data on recovery of ferrous metals from major appliances are taken from a survey conducted by the Steel Recycling Institute. Recovery of ferrous metals from shredded appliances was estimated to be 2.5 million tons in 2009, leaving 1.3 million tons of appliances to be discarded. Small Appliances. This category includes items such as toasters, hair dryers, electric coffee pots, and the like. Information on shipments of small appliances was obtained from Department of Commerce data and Appliance Statistical Review. Information on weights and materials composition of discarded small appliances was obtained through manufacturer specifications and interviews. It was estimated that 1.6 million tons of small appliances were generated in 2009. A small amount of ferrous metals in small appliances is recovered through magnetic separation. 71 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Table 12 PRODUCTS GENERATED* IN THE MUNICIPAL WASTE STREAM, 1960 TO 2009 (WITH DETAIL ON DURABLE GOODS) (In thousands of tons and percent of total generation) Products Durable Goods Major Appliances Small Appliances** Furniture and Furnishings Carpets and Rugs** Rubber Tires Batteries, Lead-Acid Miscellaneous Durables Selected Consumer Electronics*** Other Miscellaneous Durables Total Miscellaneous Durables Total Durable Goods Nondurable Goods (Detail in Table 15) Containers and Packaging (Detail in Table 18) Total Product Wastes} Other Wastes Food Scraps Yard Trimmings Miscellaneous Inorganic Wastes Total Other Wastes Total MSW Generated - Weight Products Durable Goods Major Appliances Small Appliances** Furniture and Furnishings Carpets and Rugs** Rubber Tires Batteries, Lead-Acid Miscellaneous Durables Selected Consumer Electronics*** Other Miscellaneous Durables Total Miscellaneous Durables Total Durable Goods Nondurable Goods (Detail in Table 15) Containers and Packaging (Detail in Table 19) Total Product Wastes} Other Wastes Food Scraps Yard Trimmings Miscellaneous Inorganic Wastes Total Other Wastes Total MSW Generated - % Thousands of Tons 1960 1970 1980 1990 2000 2005 2007 2008 2009 1,630 2,150 1,120 Neg. 5,020 9,920 17,330 27,370 54,620 12,200 20,000 1,300 33,500 88,120 2,170 2,830 1,890 820 6,950 14,660 25,060 43,560 83,280 12,800 23,200 1,780 37,780 121,060 2,950 4,760 2,720 1,490 9,880 21 ,800 34,420 52,670 108,890 13,000 27,500 2,250 42,750 151,640 3,310 460 6,790 1,660 3,610 1,510 12,470 29,810 52,170 64,530 146,510 23,860 35,000 2,900 61,760 208,270 3,640 1,040 7,990 2,570 4,930 2,280 1,900 14,500 16,400 38,850 64,010 75,840 178,700 29,810 30,530 3,500 63,840 242,540 3,610 1,180 8,870 2,980 4,960 2,740 2,630 17,680 20,310 44,650 63,650 76,330 184,630 31 ,990 32,070 3,690 67,750 252,380 3,620 1,390 9,340 3,140 5,000 2,800 3,010 17,470 20,480 45,770 61 ,760 78,460 185,990 32,610 32,630 3,750 68,990 254,980 3,690 1,530 9,610 3,220 5,020 2,930 3,160 17,240 20,400 46,400 58,690 75,910 181,000 33,340 32,900 3,780 70,020 251 ,020 3,760 1,630 9,870 3,450 4,730 2,800 3,190 17,210 20,400 46,640 53,440 71 ,570 171,650 34,290 33,200 3,820 71,310 242,960 Percent of Total Generation 1960 1970 1980 1990 2000 2005 2007 2008 2009 1 .8% 2.4% 1 .3% Neg. 5.7% 1 1 .3% 19.7% 31.1% 62.0% 13.8% 22.7% 1 .5% 38.0% 100.0% 1 .8% 2.3% 1 .6% 0.7% 5.7% 12.1% 20.7% 36.0% 68.8% 10.6% 19.2% 1 .5% 31.2% 100.0% 1 .9% 3.1% 1 .8% 1 .0% 6.5% 14.4% 22.7% 34.7% 71 .8% 8.6% 18.1% 1 .5% 28.2% 100.0% 1 .6% 0.2% 3.3% 0.8% 1 .7% 0.7% 6.0% 14.3% 25.0% 31.0% 70.3% 1 1 .5% 16.8% 1 .4% 29.7% 100.0% 1.5% 0.4% 3.3% 1.1% 2.0% 0.9% 0.8% 6.0% 6.8% 16.0% 26.4% 31.3% 73.7% 12.3% 12.6% 1 .4% 26.3% 100.0% 1 .4% 0.5% 3.5% 1 .2% 2.0% 1.1% 1 .0% 7.0% 8.0% 17.7% 25.2% 30.2% 73.2% 12.7% 12.7% 1 .5% 26.8% 100.0% 1.4% 0.5% 3.7% 1.2% 2.0% 1.1% 1.2% 6.9% 8.0% 18.0% 24.2% 30.8% 72.9% 12.8% 12.8% 1 .5% 27.1% 100.0% 1 .5% 0.6% 3.8% 1 .3% 2.0% 1 .2% 1 .3% 6.9% 8.1% 18.5% 23.4% 30.2% 72.1% 13.3% 13.1% 1 .5% 27.9% 100.0% 1 .5% 0.7% 4.1% 1 .4% 1 .9% 1 .2% 1 .3% 7.1% 8.4% 19.2% 22.0% 29.5% 70.6% 14.1% 13.7% 1 .6% 29.4% 100.0% * Generation before materials recovery or combustion.

Source: Franklin Associates, A Division of ERG 74 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Furniture and Furnishings. Data on sales of furniture and furnishings are provided by the Department of Commerce in dollars. These data are converted to tons using factors developed for this study over the years. For example, factors are developed by applying sales growth statistics (expressed as constant dollars) in household and office furniture, curtains, and mattresses to textile consumption (in tons) in household and office furniture, curtains, and mattresses manufacturing for those years where consumption data are available. These factors are then applied to those years where sales statistics are available but consumption data are not available. Adjustments are made for imports and exports and adjustments are made for the lifetimes of the furniture. Generation of furniture and furnishings represents products at the end-of-life (after primary use and reuse by secondary owners). Generation of furniture and furnishings in MSW has increased from 2.2 million tons in 1960 to 9.9 million tons in 2009 (4.1 percent of total MSW). The only recovery of materials from furniture identified was mattress recovery. According to an industry representative, mattress recovery is estimated at 10,000 tons. Wood is the largest material category in furniture, with ferrous metals second. Plastics, glass, and other materials are also found in furniture. Carpets and Rugs. An industry publication, Carpet and Rug Industrial Review, publishes data on carpet sales in square yards. These data are converted to tons using pounds per square yard factors developed for this report. In recent years, carpet sales from the Department of Commerce Current Industrial Report Carpet and Rug series have been used. An estimated 3.5 million tons of carpets and rugs were generated in MSW in 2009, which was 1.4 percent of total generation. Recovery of carpet fiber, backing, and padding - estimated from industry data - was 270,000 tons in 2009 (7.8 percent of carpet generation). 75 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Vehicle Tires. The methodology for estimating generation of rubber tires for automobiles and trucks is based on data on replacement tires purchased and vehicles deregistered as reported by the U. S. Department of Commerce. It is assumed that for each replacement tire purchased, a used tire enters the waste management system, and that tires on deregistered vehicles also enter the waste management system. Retreaded tires are treated as a diversion out of the waste stream; they are assumed to re-enter the waste stream after two years of use. The quantities of tires in units are converted to weight and materials composition using factors developed for this series of reports. In addition to rubber, tires include relatively small amounts of textiles and ferrous metals. Generation of rubber tires increased from 1.1 million tons in 1960 to 4.7 million tons in 2009 (1.9 percent of total MSW). Since 2000, the generation of rubber tires has remained fairly constant. Data on recovery of tires are based on data from the Scrap Tire Management Council. The tire recovery rate increased from 26.2 percent in 2000 to 35.3 percent in 2009. From 2005 to 2008, the quantity of tires generated and recovered through recycling remained relatively steady. In 2009, the quantity of tires generated and recovered through recycling decreased; however, the recycling rate remained about the same as 2008. After recovery, 3.1 million tons of tires were discarded in 2009. (Tires going to combustion facilities as fuel are included in the combustion estimates in Chapter 3.) Lead-Acid Batteries. The methodology for estimating generation of lead-acid batteries is similar to the methodology for rubber tires as described above. An estimated 2.8 million tons of lead-acid batteries from automobiles, trucks, and motorcycles were generated in MSW in 2009 (1.2 percent of total generation). The Battery Council International provided the most recent data on recovery of batteries. Recovery of batteries for recycling has fluctuated between 70 percent and 96 percent; recovery has increased since 1980 as a growing number of communities have restricted batteries from disposal at landfills or combustion facilities. In 2009, 95.7 percent of the lead in these batteries was estimated to be recovered for recycling as well as substantial quantities of the polypropylene 76 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight battery casings. Discards after recycling of these batteries were 120,000 tons in 2009. (Some electrolytes and other materials in batteries are removed from the municipal solid waste stream along with recovered lead and polypropylene; these materials are counted as "recovered" along with the recyclable materials.) Miscellaneous Durable Goods. Miscellaneous durable goods include consumer electronics such as television sets, videocassette recorders, and personal computers; luggage; sporting equipment; and the like. An estimated 20.4 million tons of these goods were generated in 2009, amounting to 8.4 percent of MSW generated. As in recent previous updates of this report, generation of selected consumer electronic products was estimated as a subset of miscellaneous durable goods. In 2009, an estimated 3.2 million tons of these goods were generated. Of this, approximately 600,000 tons of selected consumer electronics were collected for recycling. Selected consumer electronics include products such as TVs, VCRs, DVD players, video cameras, stereo systems, telephones, and computer equipment. EPA has analyzed television, computer products, and cell phone management separately in the 2010 report Electronics Waste Management in the United States Through 2009. The miscellaneous durable goods category, as a whole, includes ferrous metals as well as plastics, glass, rubber, wood, and other metals. An estimated 310,000 tons of ferrous metals were estimated to have been recovered from this category through pre-combustion and post- combustion magnetic separation at MSW combustion facilities in 2009, bringing total recovery from this category to 910,000 tons. Discards of miscellaneous durable goods were 19.5 million tons in 2009. Nondurable Goods The Department of Commerce defines nondurable goods as those products having a lifetime of less than three years, and this definition was followed for this report to the extent possible. 77 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Products made of paper and paperboard comprise the largest portion of nondurable goods. Other nondurable products include paper and plastic plates, cups, and other disposable food service products; disposable diapers; clothing and footwear; linens; and other miscellaneous products. (See Tables 15 through 17.) Generation of nondurable goods in MSW was 53.4 million tons in 2009 (22.0 percent of total generation). Recovery of paper products in this category is quite significant, resulting in 18.9 million tons of nondurable goods recovered in 2009 (35.3 percent of nondurables generation). This means that 34.5 million tons of nondurable goods were discarded in 2009 (21.5 percent of total MSW discards). Paper and Paperboard Products. Generation, recovery, and discards of paper and paperboard products in nondurable goods are summarized in Tables 15 through 17. A summary for 2009 was shown earlier in Table 4. Generation of paper and paperboard nondurable products declined from 47.8 million tons in 2000 to 33.5 million tons in 2009. Each of the paper and paperboard product categories in nondurable goods is discussed briefly below. • Newspapers are the largest single component of the paper products in the nondurable goods category, at 7.8 million tons generated in 2009 (3.2 percent of total MSW). In 2009, an estimated 6.8 million tons of newspapers generated were recovered for recycling. Estimates of newspaper generation are broken down into newsprint (the majority of the weight of the newspapers) and groundwood3 inserts (primarily advertising) that are a significant portion of the total weight of newspapers. This breakdown is shown in Table 4. • Books amounted to approximately 960,000 tons, or 0.4 percent of total MSW generation, in 2009. Recovery of books is not well documented, but it was estimated that approximately 320,000 tons of books were recovered in 2009. Books are made of both groundwood and chemical pulp. 3 Groundwood papers, like newsprint, are made primarily from pulp prepared by a mechanical process. The nature of the pulp (groundwood vs. chemical) affects the potential uses for the recovered paper. 78 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Magazines accounted for an estimated 1.5 million tons, or 0.6 percent of total MSW generation, in 2009. Like books, recovery of magazines is not well documented. It was estimated that 780,000 tons of magazines were recovered in 2009. Magazines are predominantly made of coated groundwood, but some uncoated groundwood and chemical pulps are also used. Many different kinds of papers are generated in offices. For this report, office-type paper estimates include the high grade papers such as copier paper, computer printout, stationery, etc. Generation of these office papers was 5.4 million tons, or 2.2 percent of total MSW generation in 2009. These papers are almost entirely made of uncoated chemical pulp, although some amounts of groundwood are also used. It should be noted that some of these office-type papers are generated at locations other than offices, including homes and institutions such as schools. Also, other kinds of papers (e.g., newspapers, magazines, and packaging) are generated in offices, but are accounted for in other categories. An estimated 4.0 million tons of office-type papers were recovered in 2009. Directories were estimated to generate 650,000 tons (0.3 percent of total MSW) in 2009. These directories are made of groundwood. It was estimated that 240,000 tons of directories were recovered in 2009. Standard mail includes catalogs and other direct bulk mailings; these amounted to an estimated 4.7 million tons, or 1.9 percent of MSW generation, in 2009. Both groundwood and chemical pulps are used in these mailings. It was estimated that 3.0 million tons were recovered in 2009. The U.S. Postal Service has implemented a program to increase recovery of bulk mail, and many curbside collection programs also include mail. Other commercial printing includes a wide range of paper items, including brochures, reports, menus, and invitations. Both groundwood and chemical pulps 79 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight are used in these varied items. Generation was estimated at 3.5 million tons, or 1.4 percent of MSW generation, in 2009, with recovery estimated at 2.3 million tons. • Tissue paper and towels generation includes facial and sanitary tissues and table napkins, but not bathroom tissue, which is nearly all diverted from MSW into the wastewater treatment system. Other examples include decorative and laminated tissue papers and crepe papers. Tissue products are used in homes, restaurants, other commercial establishments, and institutions such as hospitals. Tissue paper and towels (not including bathroom tissue) amounted to 3.5 million tons (1.4 percent of total MSW generation) in 2009. No significant recovery of tissue products for recycling was identified, although there is some composting of these items. • Paper plates and cups include paper plates, cups, bowls, and other food service products used in homes, in commercial establishments like restaurants, and in institutional settings such as schools. Generation of these products was estimated at 1.2 million tons (0.4 percent of total MSW generation) in 2009. No significant recovery for recycling of these products was identified, although there is some composting of these items. • Other nonpackaging papers-including posters, photographic papers, cards, and games - accounted for 4.4 million tons (1.8 percent of total MSW generation) in 2009. No significant recovery for recycling of these papers was identified. Overall, generation of paper and paperboard products in nondurable goods was 33.5 million tons in 2009 (Table 4). While newspapers were recovered at the highest rate, other paper products, such as books, magazines, office papers, directories, standard mail, and other commercial printing also were recovered for recycling, and the overall recovery rate for paper in nondurables was 52.1 percent in 2009. Thus 16.1 million tons of paper in nondurables were discarded in 2009. 80 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Table 15 PRODUCTS GENERATED* IN THE MUNICIPAL WASTE STREAM, 1960 TO 2009 (WITH DETAIL ON NONDURABLE GOODS) (In thousands of tons and percent of total generation) Products Durable Goods (Detail in Table 12) Nondurable Goods Newspapers Books and Magazines Books** Magazines** Office-Type Papers Directories** Standard Mail*** Other Commercial Printing Tissue Paper and Towels Paper Plates and Cups Plastic Plates and Cups| Trash Bags** Disposable Diapers Other Nonpackaging Paper Clothing and Footwear Towels, Sheets and Pillowcases** Other Miscellaneous Nondurables Total Nondurable Goods Containers and Packaging (Detail in Table 18) Total Product Wastes^ Other Wastes Total MSW Generated - Weight Products Durable Goods (Detail in Table 12) Nondurable Goods Newspapers Books and Magazines Books** Magazines** Office-Type Papers*** Directories** Standard Mail§ Other Commercial Printing Tissue Paper and Towels Paper Plates and Cups Plastic Plates and Cups| Trash Bags** Disposable Diapers Other Nonpackaging Paper Clothing and Footwear Towels, Sheets and Pillowcases** Other Miscellaneous Nondurables Total Nondurables Containers and Packaging (Detail in Table 19) Total Product Wastes^ Other Wastes Total MSW Generated - % Thousands of Tons 1960 9,920 1970 14,660 1980 21,800 1990 29,810 2000 38,850 2005 44,650 2007 45,770 2008 46,400 2009 46,640 7,110 1,920 1,520 1,260 1,090 270 Neg. 2,700 1,360 100 17,330 27,370 54,620 33,500 88,120 9,510 2,470 2,650 2,130 2,080 420 350 3,630 1,620 200 25,060 43,560 83,280 37,780 121,060 1 1 ,050 3,390 4,000 3,120 2,300 630 190 1,930 4,230 2,170 1,410 34,420 52,670 108,890 42,750 151,640 13,430 970 2,830 6,410 610 3,820 4,460 2,960 650 650 780 2,700 3,840 4,010 710 3,340 52,170 64,530 146,510 61,760 208,270 14,790 1,240 2,230 7,420 680 5,570 7,380 3,220 960 870 850 3,230 4,250 6,470 820 4,030 64,010 75,840 178,700 63,840 242,540 12,790 1,100 2,580 6,620 660 5,830 6,440 3,460 1,160 930 1,060 3,410 4,490 7,890 980 4,250 63,650 76,330 184,630 67,750 252,380 10,780 1,270 2,550 6,060 760 5,910 6,200 3,500 1,230 860 1,070 3,730 4,260 8,320 1,100 4,160 61,760 78,460 185,990 68,990 254,980 8,800 1,340 2,050 6,050 840 5,510 5,130 3,460 1,250 780 930 3,770 4,630 8,820 1,160 4,170 58,690 75,910 181,000 70,020 251 ,020 7,760 960 1,450 5,380 650 4,650 3,490 3,490 1,170 900 1,000 3,810 4,420 9,080 1,230 4,000 53,440 71 ,570 171,650 71,310 242,960 Percent of Total Generation 1960 1 1 .3% 1970 12.1% 1980 14.4% 1990 14.3% 2000 16.0% 2005 17.7% 2007 18.0% 2008 18.5% 2009 19.2% 8.1% 2.2% 1 .7% 1 .4% 1 .2% 0.3% Neg. 3.1% 1 .5% 0.1% 19.7% 31.1% 62.0% 38.0% 100.0% 7.9% 2.0% 2.2% 1 .8% 1 .7% 0.3% 0.3% 3.0% 1 .3% 0.2% 20.7% 36.0% 68.8% 31 .2% 100.0% 7.3% 2.2% 2.6% 2.1% 1 .5% 0.4% 0.1% 1 .3% 2.8% 1 .4% 0.9% 22.7% 34.7% 71 .8% 28.2% 100.0% 6.4% 0.5% 1 .4% 3.1% 0.3% 1 .8% 2.1% 1 .4% 0.3% 0.3% 0.4% 1 .3% 1 .8% 1 .9% 0.3% 1 .6% 25.0% 31 .0% 70.3% 29.7% 100.0% 6.1% 0.5% 0.9% 3.1% 0.3% 2.3% 3.0% 1 .3% 0.4% 0.4% 0.4% 1 .3% 1 .8% 2.7% 0.3% 1 .7% 26.4% 31 .3% 73.7% 26.3% 100.0% 5.1% 0.4% 1 .0% 2.6% 0.3% 2.3% 2.6% 1 .4% 0.5% 0.4% 0.4% 1 .4% 1 .8% 3.1% 0.4% 1 .7% 25.2% 30.2% 73.2% 26.8% 1 00.0% 4.2% 0.5% 1 .0% 2.4% 0.3% 2.3% 2.4% 1 .4% 0.5% 0.3% 0.4% 1 .5% 1 .7% 3.3% 0.4% 1 .6% 24.2% 30.8% 72.9% 27.1% 100.0% 3.5% 0.5% 0.8% 2.4% 0.3% 2.2% 2.0% 1 .4% 0.5% 0.3% 0.4% 1 .5% 1 .8% 3.5% 0.5% 1 .7% 23.4% 30.2% 72.1% 27.9% 100.0% 3.2% 0.4% 0.6% 2.2% 0.3% 1 .9% 1 .4% 1 .4% 0.5% 0.4% 0.4% 1 .6% 1 .8% 3.7% 0.5% 1 .6% 22.0% 29.5% 70.6% 29.4% 100.0% * Generation before materials recovery or combustion.

Details may not add to totals due to rounding. Source: Franklin Associates, A Division of ERG 83 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Plastic Plates and Cups. This category includes plastic plates, cups, glasses, dishes and bowls, hinged containers, and other containers used in food service at home, in restaurants and other commercial establishments, and in institutional settings such as schools. These items are made primarily of polystyrene resin. An estimated 900,000 tons of these products were generated in 2009, or 0.4 percent of total MSW (Table 15). No significant recovery for recycling was identified in 2009. Trash Bags. This category includes plastic trash bags made of high-density polyethylene and low-density polyethylene for both indoor and outdoor use. Generation of plastic trash bags amounted to 1.0 million tons in 2009 (0.4 percent of MSW generation). No significant recovery for recycling was identified. Disposable Diapers. This category includes estimates of both infant diapers and adult incontinence products. Generation was estimated using data on sales of the products along with information on average weights and composition. An estimated 3.8 million tons of disposable diapers were generated in 2009, or 1.6 percent of total MSW generation. (This tonnage includes an adjustment for the urine and feces contained within the discarded diapers.) The materials portion of the diapers includes wood pulp, plastics (including the super-absorbent materials now present in most diapers), and tissue paper. No significant recycling or composting of disposable diapers was identified in 2009. Clothing and Footwear. Generation of clothing and footwear was estimated to be 9.1 million tons in 2009 (3.7 percent of total MSW). Textiles, rubber, and leather are major materials components of this category, with some plastics present as well. Generation estimates for these products are based on sales data from the Department of Commerce along with data on average weights for each type of products included. Adjustments are made for net imports of these products based on Department of Commerce data. 84 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight The Council for Textile Recycling has reported on recovery of textiles for exports, reprocessing, and reuse. Based on their data, it was estimated that 1.3 million tons of textiles in clothing were recovered for recycling in 2009. (Reuse occurs before generation and is not included in the generation or recycling estimates.) Towels, Sheets, and Pillowcases. An estimated 1.2 million tons of towels, sheets, and pillowcases were generated in 2009. Generation was estimated using a methodology similar to that for clothing. An estimated 210,000 tons of these textiles were recovered for export or recycling in 2009. Other Miscellaneous Nondurables. Generation of other miscellaneous nondurables was estimated to be 4.0 million tons in 2009 (1.6 percent of MSW). The primary material component of miscellaneous nondurables is plastics, although some aluminum, rubber, and textiles also are present. Typical products in miscellaneous nondurables include shower curtains and other household items, disposable medical supplies, novelty items, and the like. Generation of plastic products in miscellaneous nondurables is taken from resin sales data published annually by the American Chemistry Council. Generation of other materials in these nondurable products is estimated based on information in past reports in this series. Containers and Packaging Containers and packaging make up a major portion of MSW, amounting to 71.6 million tons of generation in 2009 (29.5 percent of total generation). Generation in this category has recently trended downward; Table 18 shows a 3.3 percent decrease between 2007 and 2008 followed by a 5.7 percent decrease between 2008 and 2009 (to 71.6 million tons). Generation of all packaging materials decreased (with the exception of wood) over this time period, with a greater rate of reduced generation between 2008 and 2009. 85 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Steel packaging exhibited the greatest percentage decline; a 4.5 percent decrease between 2007 and 2008 and a 14.5 percent decrease between 2008 and 2009. Aluminum packaging generation declined only 2.1 percent over the two year period 2007 to 2009. Paper and paperboard packaging generation declined 4.1 percent between 2007 and 2008 and 8.7 percent between 2008 and 2009 (12.5 percent over the two year period). Plastic packaging and glass packaging generation exhibited a slower rate of decline; plastic packaging generation decreased 4.5 percent from 2007 and 2008 and 3.7 percent between 2008 and 2009 (8.1 percent decline over the two year period), and glass packaging generation declined 3.5 percent between 2007 and 2008 and 3.9 percent between 2008 and 2009 (7.2 percent between 2007 and 2009). Generation, recovery, and discards of containers and packaging are shown in detail in Tables 18 through 23. There is substantial recovery of many container and packaging products, especially corrugated containers. In 2009, 47.8 percent of containers and packaging generated was recovered for recycling. Because of this recovery, containers and packaging comprised 23.2 percent of total MSW discards in 2009. Containers and packaging in MSW are made of several materials: paper and paperboard, glass, steel, aluminum, plastics, wood, and small amounts of other materials. Material categories are discussed separately below. Glass Containers. Glass containers include beer and soft drink bottles (which include carbonated drinks and non-carbonated waters, teas, flavored drinks containing not more than 10 percent fruit juice and ready-to-drink alcoholic coolers and cocktails), wine and liquor bottles, and bottles and jars for food, cosmetics, and other products. Prior to 2009, generation of glass containers was estimated using Department of Commerce data. In 2009, the Glass Packaging Institute provided production data. Adjustments are made for imports and exports of both empty glass containers and containers holding products, e.g., imported beer. 86 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Generation of these glass containers was 9.7 million tons in 2009, or 4.0 percent of MSW generation (Tables 18 and 19). This tonnage is lower than was generated in any of the previous years. An estimated 3.0 million tons of glass containers were recovered for recycling, or 31.1 percent of generation, in 2009. Glass container discards were 6.7 million tons in 2009, or 4.1 percent of total MSW discards. Steel Containers and Packaging. Steel food and other cans, and other steel packaging (e.g., strapping, crowns, and steel barrels and drums), totaled 2.3 million tons in 2009 (0.9 percent of total MSW generation), with most of that amount being cans for food products (Tables 18 and 19). Generation estimates are based on data supplied by the Steel Recycling Institute (SRI), the Reusable Industrial Packaging Association, and the Can Manufacturers Institute (CMI). Estimates include adjustments for net imports. The Steel Recycling Institute (SRI) provided recovery data for steel containers and packaging. An estimated 1.5 million tons of steel packaging were recovered in 2009, or 66.2 percent of generation. The estimates include recovery from residential sources; pre-combustion and post-combustion magnetic separation of steel cans and other ferrous products at MSW combustion facilities; and recycling of drums and barrels not suitable for reconditioning. Aluminum Containers and Packaging. Aluminum containers and packaging include beer and soft drink cans (including all carbonated and non-carbonated soft drinks, tea, tonic, waters, and juice beverages), other cans, and foil and closures (including semi rigid foil containers, caps, closures, and flexible packaging). Aluminum can generation has been estimated based on can shipments data from the Can Manufacturers Institute and the Aluminum Association and can weight data from the Aluminum Association, while estimates of the net import of unfilled aluminum cans is based on Department of Commerce data. Other aluminum packaging is based on Aluminum Association data. 87 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Prior to 2000, the Can Manufacturers Institute published data on consumption of beverages in aluminum cans. After 2000, the Aluminum Association provided consumption data. The consumption data are adjusted for imports and exports of beverages in cans, and therefore are more accurate for generation calculations than shipments alone. Total aluminum container and packaging generation in 2009 was 1.8 million tons, or 0.8 percent of total MSW generation. Aluminum can recovery data are provided by the Aluminum Association; the industry association recovery number includes imported used beverage cans (UBC). The imported UBC are subtracted from the tonnage of UBC reported by the Aluminum Association to have been melted by U.S. end-users and recovered for export. Thus, the aluminum can recovery rate reported here is somewhat less than that published by the Aluminum Association. Recovery of aluminum beverage cans in 2009 was 690,000 tons, or 50.7 percent of generation. Recovery data for the other aluminum packaging categories are not available for 2009. After recovery for recycling, 1.2 million tons of aluminum packaging were discarded in 2009. 88 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Table 18 PRODUCTS GENERATED* IN THE MUNICIPAL WASTE STREAM, 1960 TO 2009 (WITH DETAIL ON CONTAINERS AND PACKAGING) (In thousands of tons) Products Durable Goods (Detail in Table 12) Nondurable Goods (Detail in Table 15) Containers and Packaging Glass Packaging Beer and Soft Drink Bottles** Wine and Liquor Bottles Other Bottles & Jars Total Glass Packaging Steel Packaging Beer and Soft Drink Cans Cans Other Steel Packaging Total Steel Packaging Aluminum Packaging Beer and Soft Drink Cans Other Cans Foil and Closures Total Aluminum Packaging Paper & Paperboard Pkg Corrugated Boxes Gable Top/Aseptic Cartons:): Folding Cartons Other Paperboard Packaging Bags and Sacks Wrapping Papers Other Paper Packaging Total Paper & Board Pkg Plastics Packaging PET Bottles and Jars HOPE Natural Bottles Other Containers Bags and Sacks Wraps Subtotal Bags, Sacks, and Wraps Other Plastics Packaging Total Plastics Packaging Wood Packaging Other Misc.

Source: Franklin Associates, A Division of ERG 94 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Paper and Paperboard Containers and Packaging. Corrugated boxes are the largest single product category of MSW at 27.2 million tons generated, or 11.2 percent of total generation, in 2009. Corrugated boxes also represent the largest single category of product recovery; at 22.1 million tons of recovery in 2009, 81.3 percent of boxes generated were recovered. After recovery, 5.1 million tons of corrugated boxes were discarded, or 3.2 percent of MSW discards in 2009. Other paper and paperboard packaging in MSW includes gable top and aseptic cartons (includes milk, juice, and other products packaged in gable top cartons and liquid food aseptic cartons), folding cartons (e.g., cereal boxes, frozen food boxes, some department store boxes), bags and sacks, wrapping papers, and other paper and paperboard packaging (primarily set-up boxes such as shoe, cosmetic, and candy boxes). Overall, paper and paperboard containers and packaging totaled 34.9 million tons of MSW generation in 2009, or 14.4 percent of total generation. While recovery of corrugated boxes is by far the largest component of paper packaging recovery, smaller amounts of other paper packaging products are recovered (estimated at about 3.0 million tons in 2009). The overall recovery rate for paper and paperboard packaging in 2009 was 71.8 percent. Other paper packaging such as cartons and sacks is mostly recovered as mixed papers. Plastic Containers and Packaging. Many different plastic resins are used to make a variety of packaging products. Some of these include polyethylene terephthalate (PET) soft drink and water bottles, high-density polyethylene (HDPE) milk and water jugs, film products (including bags and sacks) made of low-density polyethylene (LDPE), and other containers and other packaging (including clamshells, trays, caps, lids, egg cartons, loose fill, produce baskets, coatings, closures, etc.) made of polyvinyl chloride, polystyrene, polypropylene, and other resins. Estimates of generation of plastic containers and packaging are based on data on resin sales by end use published annually by the American Chemistry Council's annual plastics resin survey. 95 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Plastic containers and packaging have exhibited rapid growth in MSW, with generation increasing from 120,000 tons in 1960 (0.1 percent of generation) to 12.5 million tons in 2009 (5.2 percent of MSW generation). (Note: plastic packaging as a category in this report does not include single-service plates and cups and trash bags, which are classified as nondurable goods.) Estimates of recovery of plastic products are based on data published annually by the American Chemistry Council supplemented with additional industry data. PET bottles and jars were estimated to have been recovered at a 28.0 percent rate in 2009 (720,000 tons). Recovery of HDPE natural bottles (e.g., milk and water bottles) was estimated to have been 220,000 tons, or 28.9 percent of generation. Overall, recovery of plastic containers and packaging was estimated to be 1.7 million tons, or 13.7 percent in 2009. Discards of plastic packaging thus were 10.8 million tons in 2009, or 6.7 percent of total MSW generation. Wood Packaging. Wood packaging includes wood crates and pallets (mostly pallets). Data on production of wood packaging are from the National Wood Pallet and Container Association, and more recently, the USDA Forest Service Southern Research Station and Virginia Polytechnic Institute. In 2009, 10.0 million tons of wood pallets and other wood packaging were estimated to have been generated, or 4.1 percent of total MSW generation. Wood pallet recovery for recycling (usually by chipping for uses such as mulch or bedding material, but excluding wood combusted as fuel) was estimated at 2.2 million tons in 2009. Accounting for pallet reuse and recovery for recycling, wood packaging discards were 7.8 million tons in 2009, or 4.9 percent of total MSW discards. Other Packaging. Estimates are included for some other miscellaneous packaging such as bags made of textiles, small amounts of leather, and the like. These latter quantities are not well documented; it was estimated that 280,000 tons were generated in 2009. 96 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Summary of Products in Municipal Solid Waste The materials composition of municipal solid waste generation by product category is illustrated in Figure 14. This figure shows graphically that generation of durable goods has increased very gradually over the years. Nondurable goods and containers and packaging have accounted for the large increases in MSW generation. Figure 14.

Paper and paperboard made up 62.7 percent of nondurables in MSW generation, with plastics contributing 12.4 percent, and textiles 16.8 percent. Other materials contributed lesser percentages. After recovery for recycling, paper and paperboard were 46.5 percent of nondurable discards, with plastics being 19.2 percent, and textiles 21.8 percent. The materials composition of containers and packaging in MSW in 2009 is shown in Figure 16. By weight, paper and paperboard products made up 48.8 percent of containers and packaging generation; plastics accounted for 17.5 percent. Glass was 13.5 percent, wood was 14.4 percent, and metals were 5.8 percent. The percentage of materials discards from containers and packaging is affected by recovery for recycling. After recovery for recycling, paper and paperboard dropped to 26.4 percent of discards. Glass containers accounted for 17.8 percent of discards of containers and packaging, plastics were 28.9 percent, wood was 21.7 percent, and metals were 5.2 percent. 98 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Figure 15.

This compares to 1990, when total generation of MSW was 208.3 million tons. • Paper and paperboard products made up the largest percentage of all the materials in MSW, at 28.2 percent of total generation. Generation of paper and paperboard products declined from 87.7 million tons in 2000 to 68.4 million tons in 2009. Generation of newspapers has been declining since 2000, and this trend is expected to continue, partly due to decreased page size, but also due to increased use of electronic communication of news. Generation of office-type (high grade) papers also has been in decline, due at least partially to increased use of electronic transmission of reports, etc. Paper and paperboard products have ranged between 34 and 28 percent of generation since 2005. • Yard trimmings comprised the third largest material category, estimated at 33.2 million tons, or 13.7 percent of total generation, in 2009. This compares to 35.0 million tons (16.8 percent of total generation) in 1990. The decline in yard trimmings generation since 1990 is largely due to state legislation discouraging yard trimmings disposal in landfills, including source reduction measures such as backyard composting and leaving grass trimmings on the yard. 101 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight • Plastic products generation in 2009 was 29.8 million tons, or 12.3 percent of generation. This was a decrease of 920,000 tons from 2007 to 2009. This decrease in plastics generation came mostly from the containers and packaging category. Although plastics generation has grown from 8.2 percent of generation in 1990 to 12.3 percent in 2009, plastic generation as a percent of total generation has remained fairly steady over the past few years. MSW Recovery • Recovery of materials in MSW increased from 5.6 million tons in 1960 (6.4 percent of total generation) to 69.5 million tons in 2000 (28.6 percent of generation) to 82.0 million tons in 2009 (33.8 percent of generation). • Although recovery of products and other wastes (food scraps and yard trimmings) in MSW decreased 1.8 million tons from 2008 to 2009, generation also decreased (8 million tons from 2008 to 2009). The result is an increase in the recovery rate from 33.4 percent in 2008 to 33.8 percent in 2009. • Recovery of paper and paperboard products, the largest component of recovery, increased from 55.5 percent in 2008 to 62.1 percent in 2009. • The increase in recovery of paper and paperboard products over the longer term has been due to increases in recovery, over time, from all categories: newspapers, books, magazines, office papers, directories, Standard mail (advertisements, circulars, etc.), and other commercial printing. Between 2008 and 2009, all paper products showed increased recovery rates. • The newspaper recovery rate increased from 88.0 percent to 88.1 percent between 2008 and 2009. Newspaper generation decreased from 8.8 million tons in 2008 to 7.8 million tons in 2009. As generation of newspapers declines, this raises a 102 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight question as to whether much increase in tonnage of newspapers recovered can be achieved. • Containers and packaging recovery increased from 34.1 million tons in 2008 to 34.2 million tons in 2009; percentage recovery increased from 44.9 percent to 47.8 percent. Nondurable goods recovery decreased from 19.3 million tons in 2008 to 18.9 million tons in 2009. However, due to decreased generation, the percentage recovery of nondurable goods increased from 32.9 percent to 35.3 percent. • Measured by tonnage, the most recovered products and materials in 2009 were corrugated boxes (22.1 million tons), yard trimmings (19.9 million tons), newspapers (6.8 million tons), high grade office papers (4.0 million tons), standard mail (3.0 million tons), glass containers (3.0 million tons), lead-acid batteries (2.7 million tons), major appliances (2.5 million tons), folding cartons (2.5 million tons), other commercial printing (2.3 million tons), wood packaging (2.2 million tons), tires (1.7 million tons), and steel cans (1.3 million tons). Collectively, these products accounted for 90 percent of total MSW recovery in 2009. • Measured by percentage of generation, products with the highest recovery rates in 2009 were lead-acid batteries (95.7 percent), newspapers (88.1 percent), corrugated boxes (81.3 percent), office-type papers (74.2 percent), major appliances (66.8 percent), steel packaging (66.2 percent), yard trimmings (59.9 percent), other commercial printing (66.2 percent), aluminum cans (50.7 percent), standard mail (63.4 percent), magazines (53.8 percent), folding cartons (50.0 percent), tires (35.3 percent), and glass packaging (31.1 percent). 103 ------- Chapter 2 Characterization of Municipal Solid Waste by Weight Long Term Trends • Generation of MSW has increased (except in recession years), from 88.1 million tons in 1960 to 243 million tons in 2009. Due to the depressed economy, generation decreased in 2008 and again in 2009. • Generation of paper and paperboard, the largest material component of MSW, fluctuates from year to year, but has decreased from 87.7 million tons in 2000 to 68.4 million tons in 2009. Generation of yard trimmings has increased since 2000. Generation of other material categories also fluctuates from year to year, but overall MSW generation increased from 1960 to 2007, with the trend reversing after 2007. • In percentage of total MSW generation, recovery for recycling (including composting) did not exceed 15 percent until 1990. Growth in the recovery rate to current levels (33.8 percent) reflects a rapid increase in the infrastructure for recovery and expansion of domestic and foreign markets over the last decade. • Recovery (as a percentage of generation) of most materials in MSW has increased dramatically over the last 39 years.

The four components are put into context in Figure 17. This chapter addresses the major activities within an integrated waste management system: source reduction, recycling (including composting), combustion with energy recovery, and disposal. Source reduction activities have the effect of reducing MSW generation, while other management alternatives deal with MSW once it is generated. 148 ------- Chapter 3 Management of Municipal Solid Waste Figure 17.

Chapter 3 discusses the current MSW management infrastructure. Current solid waste collection, processing, combustion with energy recovery, and disposal programs and facilities are highlighted with tables and figures. It also presents estimates for quantities of waste landfilled, which are obtained by subtracting the amounts recovered for recycling and composting and the amounts combusted with energy recovery from total MSW generation. SOURCE REDUCTION Since 1960, the amount of waste each person creates has increased from 2.68 to 4.34 pounds per day. An effective way to stop this trend is by preventing waste from being generated in the first place. 149 ------- Chapter 3 Management of Municipal Solid Waste Source reduction is gaining more attention as an important solid waste management option. Source reduction, often called "waste prevention," is defined by EPA as "any change in the design, manufacturing, purchase, or use of materials or products (including packaging) to reduce their amount or toxicity before they become municipal solid waste. Prevention also refers to the reuse of products or materials." Thus, source reduction activities affect the waste stream before the point of generation. In this report, MSW is considered to have been generated if it is placed at curbside or in a receptacle such as a dumpster for pickup, or if it is taken by the generator to another site for recycling (including composting) or disposal. Source reduction encompasses a very broad range of activities by private citizens, communities, commercial establishments, institutional agencies, and manufacturers and distributors. Examples of source reduction actions (Table 24) include: • Redesigning products or packages so as to reduce the quantity of materials or the toxicity of the materials used, by substituting lighter materials for heavier ones and lengthening the life of products to postpone disposal. • Using packaging that reduces the amount of damage or spoilage to the product. • Reducing amounts of products or packages used through modification of current practices by processors and consumers. • Reusing products or packages already manufactured. • Managing non-product organic wastes (food scraps, yard trimmings) through backyard composting or other on-site alternatives to disposal. 150 ------- Chapter 3 Management of Municipal Solid Waste Table 24 SELECTED EXAMPLES OF SOURCE REDUCTION PRACTICES Source Reduction Practice MSW Product Categories Durable Goods Nondurable Goods Containers & Packaging Organics Redesign Materials reduction Materials substitution Lengthen life • Downgauge metals in appliances • Use of composites in appliances and electronic circuitry • High mileage tires • Electronic components reduce moving parts • Paperless purchase orders • Regular servicing • Look at warranties • Extend warranties • Concentrates • Container lightweighting • Cereal in bags • Coffee brick • Multi-use products • Design for secondary uses • Xeriscaping Consumer Practices • Purchase long lived products • Repair • Duplexing • Sharing • Reduce unwanted mail • Purchasing: products in bulk, concentrates • Reusable bags Reuse By design Secondary • Modular design • Borrow or rent for temporary use • Give to charity • Buy or sell at garage sales • Envelopes • Clothing • Waste paper scratch pads • Reusable pallets • Returnable secondary packaging • Loosefill • Grocery sacks • Dairy containers • Glass and plastic jars Reduce/Eliminate Toxins • Eliminate RGBs • Soy ink, waterbased • Waterbased solvents • Reduce mercury • Replace lead foil on wine bottles Reduce Organics Food scraps Yard trimmings • Backyard composting • Vermi-composting • Backyard composting • Grasscycling Source: Franklin Associates, A Division of ERG Source Reduction Through Redesign Since source reduction of products and packages can save money by reducing materials and energy costs, manufacturers and packaging designers have been pursuing these activities for many years. Combined with other source reduction measures, redesign can have a significant effect on material use and eventual discards. Design for source reduction can take several approaches. An example of materials reduction is the lightweighting of aluminum beverage cans. In 2009, an aluminum beverage can weighs 0.0291 pounds; down from 0.0341 pounds per can in 1996 (close to a 15 percent reduction in weight). 151 ------- Chapter 3 Management of Municipal Solid Waste Materials substitution can make a product or package lighter. For example, there has been a continuous trend of substitution of lighter materials such as plastics and aluminum for materials such as glass and steel. The substitution also may involve a flexible package instead of a rigid package. A product or package can be redesigned to reduce weight or volume. Toxic materials in products or packaging can be replaced with non-toxic substitutes. Considerable efforts have been made in this area in the past few years. Lengthening product life delays the time when the product enters the municipal waste stream. The responsibility for lengthening product life lies partly with manufacturers and partly with consumers. Manufacturers can design products to last longer and be easier to repair. Since some of these design modifications may make products more expensive, at least initially, manufacturers must be willing to invest in new product development, and consumers must demand the products and be willing to pay for them to make the goal work. Consumers and manufacturers also must be willing to care for and repair products. Modifying Practices to Reduce Materials Use Businesses and individuals often can modify their current practices to reduce the amounts of waste generated. In a business office, electronic mail can replace printed memoranda and data. Reports can be copied on both sides of the paper (duplexed). Modifying practices can be combined with other source reduction measures to reduce generation and limit material use. Individuals and businesses can request removal from mailing lists to reduce the amount of mail received and discarded. When practical, products can be purchased in large sizes or in bulk to minimize the amount of packaging per unit of product. Concentrated products also can reduce packaging requirements. The use of reusable shopping bags reduces the quantity of plastic and paper bags produced. 152 ------- Chapter 3 Management of Municipal Solid Waste Reuse of Products and Packages Similar to lengthening product life, reuse of products and packaging delays the time when the items must finally be discarded as waste. When a product is reused, presumably purchase and use of a new product is delayed, although this may not always be true. Many of the products characterized for this report are reused in sizable quantities (e.g., furniture, wood pallets, and clothing). The recovery of products and materials for recycling (including composting) as characterized in Chapter 2 does not include reuse of products, but reuse is discussed in this section. Durable Goods. There is a long tradition of reuse of durable goods such as large and small appliances, furniture, and carpets. Often this is done informally as individuals pass on used goods to family members and friends. Other durable goods are donated to charitable organizations for resale or use by needy families. Some communities and other organizations have facilitated exchange programs for citizens, and there are for-profit retail stores that deal in used furniture, appliances, and carpets. Individuals resell other goods at garage sales, flea markets, and the like. Borrowing and sharing items like tools can also reduce the number of products ultimately discarded. There is generally a lack of data on the volume of durable goods reused in the United States, and what the ultimate effect on MSW generation might be. Nondurable Goods. While nondurable goods by their very nature are designed for short- term use and disposal, there is considerable reuse of some items classified as nondurable. In particular, footwear, clothing, and other textile goods often are reused. Much of the reuse is accomplished through the same types of channels as those described above for durable goods. That is, private individuals, charitable organizations, and retail outlets (consignment shops) all facilitate reuse of discarded clothing and footwear. In addition, considerable amounts of textiles are reused as wiping cloths before being discarded. Another often-cited waste prevention measure is the use of washable plates, cups, napkins, towels, diapers, and other such products, instead of the disposable variety. (This will 153 ------- Chapter 3 Management of Municipal Solid Waste reduce solid waste but will have other environmental effects, such as increased water and energy use.) Other reusable items are available, for example: reusable air filters, reusable coffee filters, and reconditioned printer cartridges. Containers and Packaging. Containers and packaging can be reused in two ways: they can be used again for their original purpose, or they can be used in other ways. Glass bottles are a prime example of reuse of a container for its original purpose. Refillable glass beer bottles can be collected, washed, and refilled for use again. Some years ago large numbers of refillable glass soft drink bottles were used, but single-use glass bottles, plastic bottles, and aluminum cans have largely replaced these. Considerable numbers of beer bottles are collected for refilling, often by restaurants and taverns, where the bottles can easily be collected and returned by the distributor. The Glass Packaging Institute estimates that refillable glass bottles achieve a rate of eight trips (refillings) per bottle. Another example in this category is the use of refurbished wood pallets for shipping palletized goods. It is estimated that over 9 million tons of wood pallets were refurbished and returned to service in 2009. It is also common practice to recondition steel drums and barrels for reuse. Many other containers and packages can be recycled, but are not often reused, although this practice can achieve a notable source reduction in packaging. As an example, some grocery stores will allow customers to reuse grocery sacks, perhaps allowing a refund for each sack brought back for reuse. Also, many parcel shippers will take back plastic packaging "peanuts" for reuse. Many ingenious reuses for containers and packaging are possible in the home. People reuse boxes, bags, jars, jugs, and cans for many purposes around the house. There are no reliable estimates as to how these specific activities affect the waste stream. 154 ------- Chapter 3 Management of Municipal Solid Waste Management of Organic Materials Food scraps and yard trimmings combined made up about 28 percent of MSW generation in 2009, so source reduction measures aimed at these products can have an important effect on waste generation. Composting is the usual methodology for recovering these organic materials. As defined in this report, composting of organic materials after they are taken to a central composting facility is a recycling activity. Estimates for these off-site composting activities are included in this chapter. There are several types of source reduction that take place at the point of generation (e.g., the yard of a home or business). The backyard composting of yard trimmings and certain food discards is a growing source reduction practice. There also is a trend toward leaving grass clippings on lawns, often through the use of mulching mowers. Other actions contributing to reduced organics disposal are: establishment of variable fees for collection of wastes (also known as unit-based pricing or Pay-As-You-Throw), which encourage residents to reduce the amount of wastes set out; improved technology (mulching mowers); xeriscaping (landscaping with plants that use minimal water and generate minimal waste); and certain legislation such as bans on disposal of yard trimmings in landfills. Part of the impetus for source reduction and recycling of yard trimmings is the large number of state regulations discouraging landfilling or other disposal of yard trimmings. The Composting Council and other sources reported that in 1992, 12 states (amounting to over 28 percent of the nation's population) had in effect legislation affecting management of yard trimmings. By 2009, 23 states (amounting to about 50 percent of the nation's population) had legislation discouraging the disposal of yard trimmings. In addition, some local and regional jurisdictions regulate disposal of yard trimmings. 155 ------- Chapter 3 Management of Municipal Solid Waste Measuring Source Reduction Although source reduction has been an increasingly important aspect of municipal solid waste programs since the late 1980s, the goal of actually measuring how much source reduction has taken place—how much waste prevention there has been—has proved elusive. Early attempts by localities and states often consisted of measuring a single waste stream in a single community. In time, additional research enabled proxy, or estimated values, to be developed for specific waste streams, to use on a state-wide or national level. EPA's Source Reduction Program Potential Manual and planning packet, published in 1997 (EPA530-E-97-001) provides an example of this approach. Unlike recycling, where there are actual materials to weigh all through the process, measuring source reduction means trying to measure something that no longer exists. The November 1999 National Source Reduction Characterization Report for Municipal Solid Waste in the United States (EPA 530-R-99-034) provides additional information including an explanation of a methodology that has been used to generate source reduction estimates. RECOVERY FOR RECYCLING (INCLUDING COMPOSTING) Recyclables Collection Before recyclable materials can be processed and recycled into new products, they must be collected. Most residential recycling involves curbside recyclables collection, drop-off programs, buy-back operations, and/or container deposit systems. Collection of recyclables from commercial establishments is usually separate from residential recyclables collection programs. Curbside Recyclables Collection. In 2009, more than 9,000 curbside recyclables collection programs were reported in the United States. As shown in Table 25 and Figure 18, the extent of residential curbside recycling programs varies by geographic region, with the most extensive curbside collection occurring in the Northeast. 156 ------- Chapter 3 Management of Municipal Solid Waste Curbside collection programs commonly require residents to do at least some sorting of the recyclable materials put at the curb. In recent years, however, there has been a trend toward single-stream curbside collections programs, in which no sorting is required of the residents. The American Forest & Paper Association (AF&PA) estimated that 50 percent of curbside recyclables collection programs were single-stream in 2007.4 These programs require that the materials be taken to a materials recovery facility (MRF) for processing. In 2009, over 70 percent of the U.S. population had access to curbside recyclables collection programs (based on data from states representing 48 percent of the U.S. population and shown in Table 25). In comparison, a 2009 American Beverage Association study estimated that 74 percent of the U.S. population had access to curbside recycling programs.5 The Northeast region had the largest population served - 47 million persons. In the Northeast, 85 percent of the population had access to curbside recyclables collection, while in the West 68 percent of the population had access to curbside recycling. The largest numbers of programs were located in the Northeast and Midwest regions of the country.

Drop-off Centers. Drop-off centers typically collect residential materials, although some accept materials from businesses. They are found in locations such as grocery stores, sheltered workshops, charitable organizations, city-sponsored sites, and apartment complexes. Types of materials collected vary greatly; however, drop-off centers can usually accept a greater variety of materials than a curbside collection program. It is difficult to quantify drop-off centers in the United States. It is estimated that there were 12,694 programs in 1997, according to a BioCycle survey. In 2007, the "2007 AF&PA Community Survey Executive Summary" estimated over 20,000 communities have drop-off centers. The 2009 American Beverage Association study estimated 83 percent of the U.S. population has access to drop-off collection programs. Both of these studies stated that many communities have access to both curbside and drop-off recyclables collection. In some areas, 158 ------- Chapter 3 Management of Municipal Solid Waste particularly those with sparse population, drop-off centers may be the only option for collection of recyclable materials. In other areas, they supplement other collection programs. Buy-Back Centers. A buy-back center is typically a commercial operation that pays individuals for recovered materials. This could include scrap metal dealers, aluminum can centers, waste haulers, or paper dealers. Materials are collected by individuals, small businesses, and charitable organizations. Deposit Systems. Eleven states have container deposit systems: California, Connecticut, Delaware6, Hawaii, Iowa, Maine, Massachusetts, Michigan, New York, Oregon, and Vermont (Figure 19). In these programs, the consumer pays a deposit on beverage containers at the point of purchase, which is redeemed on return of the empty containers. In California, beverage distributors also pay a per container fee. In addition to these fees, handling fees are also assessed in most of the states listed. Deposit systems generally target beverage containers, which account for about 5 percent of total MSW generation (dairy products are typically excluded). The 2007 version of this report series estimated that about 35 percent of all recovery of beverage containers comes from ten of the eleven deposit states mentioned above, and an additional 20 percent of recovered beverage containers comes from California. (Note: These recovery estimates reflect not only containers redeemed by consumers for deposit, but also containers recovered through existing curbside and drop-off recycling programs. Containers recovered through these programs eventually are credited to the distributor and counted towards the redemption rate.) 6 Delaware deposit legislation was repealed by Senate Bill 234. Deposit collection will cease on December 1, 2010. http://www.bottlebill.org/legislation/usa/delaware.htm 159 ------- Chapter 3 Management of Municipal Solid Waste Figure 19. States With Bottle Deposit Rules Source: Container Recycling Institute, 2006. Commercial Recyclables Collection. The largest quantity of recovered materials comes from the commercial sector. Old corrugated containers (OCC) and office papers are widely collected from commercial establishments. Grocery stores and other retail outlets that require corrugated packaging are part of an infrastructure that brings in the most recovered material. OCC is often baled at the retail outlet and picked up by a paper dealer. Office paper (e.g., white, mixed color, computer paper, etc.) is part of another commercial recyclables collection infrastructure. Depending on the quantities generated, businesses (e.g., banks, institutions, schools, printing operations, etc.) can sort materials and have them picked up by a paper dealer, or self deliver the materials to the recycler. It should be noted that commercial operations also make recycling available for materials other than paper. Multi-family residence recycling could be classified as either residential or commercial recyclables collection. Multi-family refuse is usually handled as a commercial account by waste haulers. These commercial waste haulers may handle recycling at multi-family dwellings (typically five or more units) as well. 160 ------- Chapter 3 Management of Municipal Solid Waste Recyclables Processing Processing recyclable materials is performed at materials recovery facilities (MRFs), mixed waste processing facilities, and mixed waste composting facilities. Some materials are sorted at the curb and require less attention. Other materials are sorted into categories at the curb, such as a paper category and a container category, with additional sorting at a facility (MRF). There is a more recent trend towards MRFs that can sort recyclable materials that are picked up unsorted (single-stream recycling). Mixed waste can also be processed to pull out recyclable and compostable materials. Materials Recovery Facilities. Materials recovery facilities vary widely across the United States, depending on the incoming materials and the technology and labor used to sort the materials. In 2009, 578 MRFs were operating in the United States, with an estimated total daily throughput of over 86,000 tons per day (Table 26). The most extensive recyclables processing throughput occurs in the Northeast and Midwest (Figure 20).

West Many MRFs are considered low technology, meaning the materials are predominantly sorted manually. MRFs classified as high technology sort recyclables using eddy currents, magnetic pulleys, optical sensors, and air classifiers. As MRFs change and grow, many low technology MRFs add high tech features. However, high technology MRFs usually include some manual sorting, reducing the distinction between high and low technology MRFs. 162 ------- Chapter 3 Management of Municipal Solid Waste Mixed Waste Processing. Mixed waste processing facilities are less common than conventional MRFs, but there are several facilities in operation in the United States, as illustrated in Figure 21. Mixed waste processing facilities receive mixed solid waste (including recyclable and non-recyclable materials), which is then loaded on conveyors. Using both mechanical and manual (high and low technology) sorting, recyclable materials are removed for further processing. In 2009, there were reported 25 mixed waste processing facilities in the U.S., handling about 23,000 tons of waste per day. The Western region has the largest concentration of these processing facilities (representing over 80 percent of the daily throughput). Figure 21.

West 163 ------- Chapter 3 Management of Municipal Solid Waste Mixed Waste Composting. Mixed waste composting starts with unsorted MSW. Large items are removed, as well as ferrous and other metals, depending on the type of operation. Mixed waste composting takes advantage of the high percentage of organic components of MSW, such as paper, food scraps and yard trimmings, wood, and other materials. In 2009, there were 12 mixed waste composting facilities, four less than was reported in 2007. Nationally, mixed waste composting facilities handled about 1,100 tons per day in 2009, down from 1,500 tons per day in 2007. In 2009, the highest processing capacity per million persons was found in the West and Midwest, as shown in Figure 22. Figure 22.

Yard trimmings composting is much more prevalent than mixed waste composting. On-site management of yard trimmings (back yard composting) is discussed earlier in this chapter, and is classified as source reduction, not recycling. In 2009, about 2,900 yard trimmings composting programs were documented from a search of state environmental websites. In 2009, about 50 percent of these programs were in the Midwest region, as shown in Figure 23. Based on 19.9 million tons of yard trimmings recovered for composting in the United States (Table 2, Chapter 2), yard trimmings composting facilities handled approximately 54,500 tons per day in 2009.

The resulting energy reduces the amount needed from other sources, and the sale of the energy helps to offset the cost of operating the facility. In past years, it was common to burn municipal solid waste in incinerators solely as a volume reduction practice; energy recovery became more prevalent in the 1980s. Total U.S. MSW combustion with energy recovery, referred to as waste-to-energy (WTE) combustion, had a 2009 design capacity of 94,721 tons per day. There were 87 WTE facilities in 2009 (Table 27), down from 102 in 2000. In tons of capacity per million persons, the Northeast region had the most MSW combustion capacity in 2009 (Figure 24). In addition to facilities combusting mixed MSW (processed or unprocessed), there is a small but growing amount of combustion of source-separated MSW. In particular, rubber tires have been used as fuel in cement kilns, utility boilers, pulp and paper mills, industrial boilers, and dedicated scrap tire-to-energy facilities. In addition, there is combustion of wood wastes and some paper and plastic wastes, usually in boilers that already burn some other type of solid fuel. For this report, it was estimated that about 3.1 million tons of MSW were combusted in this manner in 2009, with tires contributing a majority of the total. 166 ------- Chapter 3 Management of Municipal Solid Waste Table 27 MUNICIPAL WASTE-TO-ENERGY PROJECTS, 2009 Region NORTHEAST SOUTH MIDWEST WEST U.S. Total* Number Operational 40 23 16 8 87 Design Capacity (tpd) 46,537 31,131 10,912 6,141 94,721 * Projects on hold or inactive were not included.

For the purposes of this report, it is assumed that most of these residues are landfilled. Materials processing facilities (MRFs) and compost facilities generate some residues when processing various recovered materials. These residues include materials that are unacceptable to end users (e.g., broken glass, wet newspapers), other contaminants (e.g., products made of plastic resins that are not wanted by the end user), or dirt. While residue generation varies widely, 5 to 10 percent is probably typical for a MRF. Residues from a MRF or compost facility are generally landfilled. Since the recovery estimates in this report are based on recovered materials purchased by end users rather than materials entering a processing facility, the residues are counted with other disposed materials. When municipal solid waste is combusted, a residue (usually called ash) is left behind. Years ago this ash was commonly disposed of along with municipal solid waste, but combustor ash is not counted as MSW in this report because it generally is managed separately7. (There are a number of efforts underway to reuse ash.) As a general "rule of thumb," MSW combustor ash amounts to about 25 percent (by weight) of unprocessed MSW input. This percentage will vary from facility to facility depending upon the types of waste input and the efficiency and configuration of the facility. LANDFILLS In 2009, there were 1,908 municipal solid waste landfills reported in the United States. Table 28 and Figure 25 show the number of landfills in each region. The South and West had the largest number of landfills. Thirty-eight percent of the landfills are located in the West, 35 percent in the South, and 21 percent in the Midwest. Less than 7 percent are located in the Northeast. 7 Note that many combustion facilities do magnetic separation of residues to recover ferrous metals, e.g., steel cans and steel in other miscellaneous durable goods. This recovered steel is included in the total recovery of ferrous metals in MSW reported in Chapter 2. 168 ------- Chapter 3 Management of Municipal Solid Waste T3 CO 800 600 400 200 Table 28 LANDFILL FACILITIES, 2009 Number of Landfills Region NORTHEAST SOUTH MIDWEST WEST U.S. Total 128 668 394 718 1,908 Source: S/oCyc/e October 2010.

South Midwest West 169 ------- Chapter 3 Management of Municipal Solid Waste SUMMARY OF HISTORICAL AND CURRENT MSW MANAGEMENT This summary provides some perspective on historical and current municipal solid waste management practices in the United States. The results are summarized in Table 29 and Figure 26. Historically, municipal solid waste generation has grown steadily (from 88 million tons in 1960 to 243 million tons at present). In the 1960s and early 1970s a large percentage of MSW was burned, with little recovery for recycling. Landfill disposal typically consisted of open dumping, often accompanied with open burning of the waste for volume reduction. Through the mid-1980s, incineration declined considerably and landfills became difficult to site, and waste generation continued to increase. Materials recovery rates increased very slowly in this time period, and the burden on the nation's landfills grew dramatically. As Figure 26 shows, discards of MSW to landfill or other disposal apparently peaked in 1990 and then began to decline as materials recovery and combustion with energy recovery increased. 170 ------- Chapter 3 Management of Municipal Solid Waste Table 29 GENERATION, MATERIALS RECOVERY, COMPOSTING, COMBUSTION, AND DISCARDS OF MUNICIPAL SOLID WASTE, 1960 TO 2009 (In thousands of tons and percent of total generation) Thousands of Tons Generation Recovery for recycling Recovery for composting* Total Materials Recovery Discards after recovery Combustion with energy recovery** Discards to landfill, other disposalf 1960 88,120 5,610 Neg. 5,610 82,510 0 82,510 1970 121,060 8,020 Neg. 8,020 113,040 400 112,640 1980 151,640 14,520 Neg. 14,520 137,120 2,700 134,420 1990 208,270 29,040 4,200 33,240 175,030 29,700 145,330 2000 242,540 53,010 16,450 69,460 173,080 33,730 139,350 2005 252,380 59,310 20,550 79,860 172,520 31,620 140,900 2007 254,980 63,090 21,710 84,800 170,180 31 ,970 138,210 2008 251 ,020 61 ,750 22,100 83,850 167,170 31 ,550 135,620 2009 242,960 61,270 20,750 82,020 160,940 29,010 131,930 Pounds per Person per Day Generation Recovery for recycling Recovery for composting* Total Materials Recovery Discards after recovery Combustion with energy recovery** Discards to landfill, other disposalf Population (thousands) 1960 2.68 0.17 Neg. 0.17 2.51 0.00 2.51 179,979 1970 3.25 0.22 Neg. 0.22 3.03 0.01 3.02 203,984 1980 3.66 0.35 Neg. 0.35 3.31 0.07 3.24 227,255 1990 4.57 0.64 0.09 0.73 3.84 0.65 3.19 249,907 2000 4.72 1.03 0.32 1.35 3.37 0.66 2.71 281,422 2005 4.67 1.10 0.38 1.48 3.19 0.58 2.61 296,410 2007 4.63 1.15 0.39 1.54 3.09 0.58 2.51 301 ,621 2008 4.52 1.11 0.40 1.51 3.01 0.57 2.44 304,060 2009 4.34 1.09 0.37 1.46 2.88 0.52 2.36 307,007 Percent of Total Generation Generation Recovery for recycling Recovery for composting* Total Materials Recovery Discards after recovery Combustion with energy recovery** Discards to landfill, other disposalf 1960 100.0% 6.4% Neg. 6.4% 93.6% 0.0% 93.6% 1970 100.0% 6.6% Neg. 6.6% 93.4% 0.3% 93.1% 1980 100.0% 9.6% Neg. 9.6% 90.4% 1 .8% 88.6% 1990 100.0% 14.0% 2.0% 1 6.0% 84.0% 14.2% 69.8% 2000 100.0% 21 .9% 6.7% 28.6% 71 .4% 13.9% 57.5% 2005 1 00.0% 23.5% 8.1% 31 .6% 68.4% 12.5% 55.9% 2007 100.0% 24.8% 8.5% 33.3% 66.7% 1 2.5% 54.2% 2008 100.0% 24.6% 8.8% 33.4% 66.6% 1 2.6% 54.0% 2009 100.0% 25.2% 8.6% 33.8% 66.2% 1 1 .9% 54.3% Composting of yard trimmings, food scraps and other MSW organic material.

November 1991. 184 ------- Appendix A Materials Flow Methodology APPENDIX A MATERIALS FLOW METHODOLOGY The materials flow methodology is illustrated in Figures A-l and A-2. The crucial first step is making estimates of the generation of the materials and products in MSW (Figure A-l). DOMESTIC PRODUCTION Data on domestic production of materials and products were compiled using published data series. U.S. Department of Commerce sources were used where available, but in several instances more detailed information on production of goods by end use is available from industry associations. The goal is to obtain a consistent historical data series for each product and/or material. CONVERTING SCRAP The domestic production numbers were then adjusted for converting or fabrication scrap generated in the production processes. Examples of these kinds of scrap would be clippings from plants that make boxes from paperboard, glass scrap (cullet) generated in a glass bottle plant, or plastic scrap from a fabricator of plastic consumer products. This scrap typically has a high value because it is clean and readily identifiable, and it is almost always recovered and recycled within the industry that generated it. Thus, recovered converting/fabrication scrap is not counted as part of the postconsumer recovery of waste. ADJUSTMENTS FOR IMPORTS/EXPORTS In some instances imports and exports of products are a significant part of MSW, and adjustments were made to account for this. 185 ------- Appendix A Materials Flow Methodology DIVERSION Various adjustments were made to account for diversions from MSW. Some consumer products are permanently diverted from the municipal waste stream because of the way they are used. For example, some paperboard is used in building materials, which are not counted as MSW. Another example of diversion is toilet tissue, which is disposed in sewer systems rather than becoming MSW. In other instances, products are temporarily diverted from the municipal waste stream. For example, textiles reused as rags are assumed to enter the waste stream the same year the textiles are initially discarded. ADJUSTMENTS FOR PRODUCT LIFETIME Some products (e.g., newspapers and packaging) normally have a very short lifetime; these products are assumed to be discarded in the same year they are produced. In other instances (e.g., furniture and appliances), products have relatively long lifetimes. Data on average product lifetimes are used to adjust the data series to account for this. RECOVERY Data on recovery of materials and products for recycling are compiled using industry data adjusted, when appropriate, with U.S. Department of Commerce import/export data. Recovery estimates of yard trimmings or food scraps for composting are developed from data provided by state officials and processors of these materials. 186 ------- Appendix A Materials Flow Methodology DISCARDS Mathematically, discards equal that portion of generation remaining after recovery for recycling and composting. Discards can be disposed through combustion with or without energy recovery or landfilling. The amount of MSW consumed at combustion facilities with energy recovery is estimated, and the difference between total discards and the amount sent to combustion for energy recovery is assumed to be landfilled or combusted without energy recovery. (This assumption is not quite accurate, as some MSW is littered or disposed on-site, e.g., by backyard burning. These amounts are believed to be a small fraction of total discards.) MUNICIPAL SOLID WASTE GENERATION, RECOVERY, AND DISCARDS The result of these estimates and calculations is a material-by-material and product-by- product estimate of MSW generation, recovery, and discards. 187 ------- Appendix A Materials Flow Methodology Domestic Production of Materials/Products Imports of Materials/Products Conversion/ fabricating Scrap Exports of Materials/Products Diversion of Materials/Products Permanent Diversion Municipal Solid Waste Generation Temporary Diversion Figure A-1.
