Executive Summary

               IN THE UNITED STATES: 2009 FACTS AND FIGURES

                               EXECUTIVE SUMMARY

OVERVIEW

       This report describes the national municipal solid waste (MSW) stream based on data
collected for 1960 through 2009. 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).

       Figures ES-1 and ES-2 show decreases in MSW generation and recycling from 2007 to
2009. 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.

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.

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.

-------
Executive Summary
       The generation and recovery of the product categories in MSW in 2009 are shown in
Table ES-5. 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
       The nondurable goods category also includes clothing and other textile products—16.2
percent of these products were recovered for recycling or export in 2009.

       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.

              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.)

THE BENEFITS OF RECYCLING

       Recycling has environmental benefits at every stage in the life cycle of a consumer
product—from the raw material with which it's made to its final method of disposal. 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.

                                    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:

-------
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.

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.

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.

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).

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.

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.

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.

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.

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.

         CHARACTERIZATION OF MUNICIPAL SOLID WASTE BY WEIGHT

INTRODUCTION

       The tables and figures in this chapter present the results of the update of EPA's municipal
solid waste characterization report through 2009. 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.

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.

       Total generation of paper and paperboard in MSW has grown from 30 million tons in
1960 to 68 million tons in 2009 (Table 1). As a percentage of total MSW generation, paper
represented 34 percent in 1960 (Table 1). The percentage has varied over time, but is estimated
to be 28.2 percent of total MSW generation in 2009.
   The term "cardboard" is often used for products made of paperboard (boxboard and containerboard), but this
   inexact term is not used in the paper industry.

       As Figure 3 illustrates, paper generation has generally increased since 1960, peaked at
about 88 million tons in 2000, and declined after 2000 to 68 million tons in 2009.

       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.

       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.

       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.

       Generation. 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.

       Recovery. 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.

       Recovery. 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.

       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).

       In durable goods, plastics are found in appliances, furniture, casings of lead-acid batteries,
and other products. (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.

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).

       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).

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.

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.

       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.

       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

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.

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.

       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.

       Recovery and Discards. 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.

       Estimated recovery of materials (including composting) is shown in Figure 12. 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.

Chapter 2                                  Characterization of Municipal Solid Waste by Weight


       The Chapter 2 section above gave a breakdown of municipal solid waste by material. 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.

Chapter 2                                  Characterization of Municipal Solid Waste by Weight

       Major Appliances. 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.

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

       Recovery of carpet fiber, backing, and padding - estimated from industry data - was
270,000 tons in 2009 (7.8 percent of carpet generation).

       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

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.

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.

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.

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.

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.

       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.

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.

       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.

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.

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.

       The materials composition of nondurable goods in 2009 is shown in Figure 15. 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.

Chapter 2                                  Characterization of Municipal Solid Waste by Weight


SUMMARY

       The data presented in this chapter can be summarized by the following observations:

MSW Generation

       •      Total generation of municipal solid waste in 2009 was 243 million tons, which
              was similar to 2000 when 242.5 million tons were generated. 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

       •       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

              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).

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.  Some examples:

                                        1970   1980  1990  2000  2009
                Paper and paperboard      15%   21%  28%  43%  62%
                Glass                    1%    5%   20%  23%  26%
                Metals                   4%    8%   24%  35%  35%

                   MANAGEMENT OF MUNICIPAL SOLID WASTE

INTRODUCTION

       EPA's tiered integrated waste management strategy includes the following components:

       •      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.

       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.

presented in Chapter 2. 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.

       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.

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.

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.

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.

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

       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.

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).

       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.

       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).

       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.

       Yard Trimmings Composting. 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.

COMBUSTION WITH ENERGY RECOVERY

       Most of the municipal solid waste combustion currently practiced in this country
incorporates recovery of an energy product (generally steam or electricity). 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.

RESIDUES FROM WASTE MANAGEMENT FACILITIES

       Whenever municipal wastes are processed, residues will remain. 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.

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.

       Recovery has increased steadily. Combustion with energy recovery, as a percentage of

generation, has been declining (11.9 percent of generation in 2009). MSW discards to landfills

rose to about 141 million tons in 2005, and then declined to 132 million tons in 2009. As a

percentage of total MSW generation, discards to landfills or other disposal has consistently

decreased-from 89 percent of generation in 1980 to about 54 percent in 2009.

                                    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.
