United States Environmental Protection Agency Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2007 The U.S. Environmental Protection Agency (EPA) has collected and reported data on the generation and disposal of waste in the United States for more than 30 years. We use this information to measure the success of waste reduction and recycling pro- grams across the country. This fact sheet summarizes information contained in our full report, Municipal Solid Waste in the United States: 2007 Facts and Figures. In 2007, Americans generated about 254 million tons of trash and recycled and com- posted 85 million tons of this material, equivalent to a 33.4 percent recycling rate (see Figure 1 and Figure 2). On average, we recycled and composted 1.5 pounds of our individual waste generation of 4.6 pounds per person per day. 300 Figure 1.

These materials range from packaging, food scraps, and grass clippings, to old sofas, computers, tires, and refrigerators. MSW does not include industrial, hazard- ous, or construction waste. In 2007, Americans recovered 63 million tons (exclud- ing composting) through recycling. This is 1.9 million tons more than in 2006. Composting recovered almost 22 million tons of waste. We combusted 32 million tons for energy recovery (about 13 percent). Subtracting out what we recycled and composted, we combusted (with energy recovery) or discarded just over 3 pounds per person per day. In 2007, paper and paperboard recovery rose to over 54 percent (45 million tons), and 64 percent of yard trimmings were recovered (see Figure 3). Metals were recycled at a rate of almost 35 percent (see Table 1). By recycling 7 million tons of metals (which includes aluminum, steel, and mixed metals), we eliminated greenhouse gas (GHG) emissions totaling close to 25 million metric tons of carbon dioxide equivalent (MMTCO E). This is equivalent to removing more than 4.5 million cars from the road for one year.* About 137 million tons of MSW (54 percent) was discarded in landfills in 2007 (see Figure 4). Over the last few decades, the generation, recycling, composting, and disposal of MSW have changed substantially. While solid waste generation has increased, from 3.66 to 4.62 pounds per person per day between 1980 and 2007, the recycling rate has also increased—from less than 10 percent of MSW generated in 1980 to over 33 percent in 2007. Disposal of waste to a landfill has decreased from 89 percent of the amount generated in 1980 to 54 percent of MSW in 2007. 1 All benefit calculations in this fact sheet are derived from EPA's WAste Reduction Model (WARM). ------- Figure 3.

Management of MSW in the United States, 2007 ------- Sources of MSW We estimated residential waste (including waste from apartment houses) to be 55 to 65 percent of total MSW generation. Waste from commercial and institutional locations, such as schools, hospitals, and businesses, amounted to 35 to 45 percent. Nationally, we recycled and composted 85 million tons of municipal solid waste. This provides an annual benefit of 193 million metric tons of carbon dioxide equivalent emissions reduced, comparable to the annual GHG emissions from more than 35 million passenger vehicles. Analyzing MSW We analyze waste by material, such as paper and paperboard, yard trimmings, food scraps, and plastics, and by major product categories, which include durable goods (such as furniture), nondurable goods (such as paper or clothing), containers and packaging (such as milk cartons and plastic wrap), and other materials (such as food scraps). Materials in MSW Total MSW generation in 2007 was 254 million tons. Organic materials continue to be the largest component of MSW. Paper and paperboard account for 33 percent, with yard trimmings and food scraps accounting for 25 percent. Plastics comprise 12 percent; metals make up 8 percent; and rubber, leather, and textiles account for almost 8 percent. Wood follows at around 6 percent and glass at 5 percent. Other miscellaneous wastes make up approximately 3 percent of the MSW generated in 2007 (see Figure 5). Figure 5.

The highest recovery rates were achieved in yard trimmings, paper and paperboard, and metafs. About 21 miffion tons of yard trimmings were composted, representing a five-fofd increase since 1990. We recycfed more than haff the paper and paperboard we gener- ated. Recycfing these organic materiafs afone kept 26 percent of MSW out of fandfiffs and combustion facifities. Recycfing amounts and rates (recovery as a percent of generation) for aff materiafs in 2007 are fisted in Tabfe 1. Recycling and composting 85 million tons of MSW saved 1.3 quadrillion Btu of energy, the equivalent of more than 10.7 billion gallons of gasoline. Products in MSW The breakdown, by weight, of waste generated in 2007 by product category is shown in Figure 6. Con- tainers and packaging made up the fargest portion of MSW generated: 31 percent, or 78 miffion tons. The second fargest portion came from nondurabfe goods, which amounted to about 25 percent, or 62 miffion tons. Yard trimmings make up the third fargest segment, accounting for 13 percent, or afmost 33 miffion tons. The generation and recovery of materiafs in the product categories, by weight and recovery as a percent of generation, are shown in Tabfe 2. This tabfe shows that the recovery of containers and packaging was the highest of the four product categories, with about 43 percent of the generated materiafs recycfed. Steef, paper products, and afuminum were the most recycfed materiafs by percentage in this category. More than 64 percent of steef packaging (mostfy cans) was recycfed. Sixty-two percent of paper and paperboard containers and packaging was recycfed, incfuding 74 percent of aff corrugated boxes. The recycfing rate for afuminum packaging was 39 percent, incfuding afmost 49 percent of afuminum beverage cans. Figure 6.

Around 28 percent of glass containers were recycled, while about 16 percent of wood packaging—mostly wood pallets—was recovered. Almost 12 percent of plas- tic containers and packaging was recycled, mostly from soft drink, milk, and water bottles. Plastic bottles were the most recycled plastic products. PET soft drink and water bottles were recovered at 37 percent. Recovery of HDPE milk and water bottles was estimated at about 28 percent (see the full 2007 MSW report). Overall recovery of nondurable goods was 35 percent in 2007. Nondurable goods generally last less than three years. Paper products, such as newspapers and high-grade office papers were the most recycled nondurable goods. Newspapers alone were recycled at a rate of nearly 78 percent. Approximately 72 per- cent of high-grade office papers and 40 percent of magazines were recovered. Forty percent of unwanted mail, 26 percent of books, and 20 percent of telephone directories were recovered for recycling in 2007 (see the full MSW report). Clothing and other textile products are included in the nondurable goods cat- egory. These products were recovered for recycling at a rate of 17 percent. Overall, almost 18 percent of durable goods were recovered in 2007. Nonferrous metals other than alu- minum had one of the highest recovery rates—around 69 percent—due to the high rate of lead recovery from lead-acid batteries. With a 99 percent recycling rate, lead-acid batteries continue to be one of the ------- most recovered products. Recovery of steel in all dura- ble goods was 27 percent, with high rates of recovery from appliances and other miscellaneous items. Measured by percentage of generation, products with the highest recovery rates in 2007 were lead-acid batteries (99 percent), newspapers (78 percent), cor- rugated boxes (74 percent), office-type papers (72 percent), major appliances (67 percent), steel packag- ing (65 percent), yard trimmings (64 percent), com- mercial printing papers (57 percent), aluminum cans (49 percent), standard mail (40 percent), magazines (40 percent), paper bags and sacks (37 percent), and PET soft drink bottles (37 percent) (see full 2007 MSW report). Recycling and Composting Collection Programs** • Approximately 8,660 curbside recycling programs exist nationwide, down from 8,875 in 2002. • About 3,510 community composting programs are operational, an increase from 3,227 in 2002.

At the national level, landfill capacity appears to be sufficient, although it is limited in some areas. • Since 1990, the total amount of MSW going to landfills dropped by about 5 million tons, from 142.3 million to 137.2 million tons in 2007 (see Table 3). Recycling just 1 ton of aluminum cans conserves more than 207 million Btu, the equivalent of 36 barrels of oil, or 1,665 gallons of gasoline. • The net per capita discard rate (after recycling, composting, and combustion for energy recovery) was 2.50 pounds per person per day, similar to the 2.51 per capita rate in 1960, when virtually no recycling occurred in the United States (see Table 4). 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. Nationally, we recycled 85 million tons of MSW. This provides an annual benefit of 193 million metric tons of carbon dioxide equivalent emissions reduced, comparable to removing the emissions from 35 mil- lion passenger cars. But the ultimate benefits from recycling are cleaner land, air, and water, overall better health, and a more sustainable economy. 10 ------- Energy Recovered from Waste Combustion • In 2007, approximately 31.9 million tons of materials, or 12.6 percent, were com- busted for energy recovery. • MSW combustion for energy recovery has remained fairly constant since 1990. Resources The report summarized in this fact sheet characterizes the MSW stream as a whole by using a materials flow methodology that relies on a mass balance approach. For example, to determine the amounts of paper recycled, information is gathered on the amounts processed by paper mills and made into new paper on a national basis, instead of counting paper col- lected at curbside on a state-by-state basis. Using data gathered from industry associations, businesses, and government sources, such as the U.S. Department of Commerce and the U.S. Census Bureau, we estimate tons of materials and products generated, recycled, and discarded. Other sources of data, such as waste characterizations and research reports performed by governments, industry, or the press, supplement these data. The benefits of recycling and composting, such as elimination of GHG emissions, are calculated using EPA's WARM methodology. Please see: www.epa.gov/warm WARM calculates and totals GHG emissions of baseline and alternative waste management practices— source reduction, recycling, composting, combustion, and landfilling. The model calculates emissions in metric tons of carbon equivalent (MTCE), metric tons of carbon dioxide equivalent (MTCO2E), and energy units (million Btu) across a wide range of material types commonly found in MSW. EPA developed GHG emissions reduction factors through a life-cycle assess- ment methodology. EPAs report, Solid Waste Manage- ment and Greenhouse Gases: A Life-Cycle Assessment of Emissions and Sinks (EPA-530-R-02-006), describes this methodology in detail (www.epa.gov/ climatechange/wycd/waste/downloads/fullreport.pdf). The full report on MSW characterization for 2007 and a summary of the WARM methodology are available on the EPA Web site along with information about waste reduction and recycling. Please see: www.epa.gov/epawaste/nonhaz/municipal/msw99.htm www.epa.gov/epawaste/conserve/rrr/index.htm 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 (33.4 percent) reflects a rapid increase in infrastructure and market demand for recovery over the last decade. 11 ------- United States Environmental Protection Agency United States Environmental Protection Agency Solid Waste and Emergency Response (5306P) Washington, DC 20460 Official Business Penalty for Private Use $300 EPA-530-F-08-018 November 2008 www.epa.gov/osw 12 ------- |
