The Current National PictureEPA began collecting and reporting data on the generation and disposition of waste in the United States more than 35 years ago. The Agency uses this information to measure the success of materials management programs across the country and to characterize the national waste stream. These Facts and Figures are current through calendar year 2018. The total generation of municipal solid waste (MSW) in 2018 was 292.4 million tons (U.S. short tons, unless specified) or 4.9 pounds per person per day. Of the MSW generated, approximately 69 million tons were recycled and 25 million tons were composted. Together, almost 94 million tons of MSW were recycled and composted, equivalent to a 32.1 percent recycling and composting rate. An additional 17.7 million tons of food were managed by other methods. Other food management includes the following management pathways: animal feed, bio-based materials/biochemical processing, co-digestion/anaerobic digestion, donation, land application and sewer/wastewater treatment. For more information on food management, check out Food: Material-Specific Data. In addition, nearly 35 million tons of MSW (11.8 percent) were combusted with energy recovery and more than 146 million tons of MSW (50 percent) were landfilled. EPA refers to trash, or MSW, as various items consumers throw away after they are used. These items include bottles and corrugated boxes, food, grass clippings, sofas, computers, tires and refrigerators. However, MSW does not include everything that may be landfilled at the local level, such as construction and demolition (C&D) debris, municipal wastewater sludge, and other non-hazardous industrial wastes. While the analysis in Facts and Figures focuses primarily on MSW, EPA has been including estimates of C&D generation and management as a separate non-hazardous waste stream in recent years. EPA is now in the process of reviewing the waste hierarchy to determine if potential changes should be made based on the latest available data and information.*MSW generation rose considerably from 2017 to 2018 mainly because EPA enhanced its food measurement methodology to more fully account for all the ways wasted food is managed throughout the food system. Management of MSW continues to be a high priority for state and local governments. This includes the source reduction of wastes before they enter the waste stream and the recovery of generated waste for recycling, composting or other methods. It also includes environmentally sound waste management through combustion with energy recovery and conversion, as well as landfilling practices that meet current standards or newly emerging waste conversion technologies. EPA developed the non-hazardous materials and waste management hierarchy in recognition that no single waste management approach is suitable for managing all materials and waste streams in all circumstances. The hierarchy ranks the various management strategies from most to least environmentally preferred. The hierarchy places emphasis on reducing, reusing, and recycling as key to sustainable materials management. GenerationThe total generation of MSW in 2018 was 292.4 million tons, which was approximately 23.7 million tons more than the amount generated in 2017. This is an increase from the 268.7 million tons generated in 2017 and the 208.3 million tons in 1990. *MSW generation rose considerably from 2017 to 2018 mainly because EPA enhanced its food measurement methodology to more fully account for all the ways wasted food is managed throughout the food system. Municipal Solid Waste Management: 1960-2018Per capita MSW generation increased from 4.5 pounds per person per day in 2017 to 4.9 pounds per person per day in 2018. The increase from 2017 to 2018 is mainly the result of EPA’s inclusion of additional wasted food management pathways. Check out Food: Material-Specific Data. Paper and paperboard products made up the largest percentage of all the materials in MSW, at 23.1 percent of total generation. Generation of paper and paperboard products declined from 87.7 million tons in 2000 to 67.4 million tons in 2018. Generation of newspapers has been declining since 2000, and this trend is expected to continue, partly due to decreased page size, but mainly due to the increased digitization of news. The generation of office-type (high grade) papers also has been in decline, due at least partially to activities such as the increased use of the electronic transmission of reports. Paper and paperboard products have ranged between 28.4 and 23.1 percent of generation since 2010. Food waste comprised the fourth largest material category, estimated at 63.1 million tons or 21.6 percent of total generation in 2018. Yard trimmings comprised the next largest material category, estimated at 35.4 million tons, or 12.1 percent of total generation, in 2018. This compares to 35 million tons (16.8 percent of total generation) in 1990. The decline in yard trimmings generation since 1990 is largely due to state legislation discouraging yard trimmings disposal in landfills, including source reduction measures such as backyard composting and leaving grass trimmings on the yard. In 2018, plastic products generation was 35.7 million tons, or 12.2 percent of generation. This was an increase of 4.3 million tons from 2010 to 2018, and it came from durable goods and the containers and packaging categories. Plastics generation has grown from 8.2 percent of generation in 1990 to 12.2 percent in 2018. Plastics generation as a percent of total generation has varied from 12.2 to 13.2 percent over the past eight years. In 2018, 2.7 million tons of selected consumer electronics were generated, representing less than 1 percent of MSW generation. Selected consumer electronics include products such as TVs, VCRs, DVD players, video cameras, stereo systems, telephones and computer equipment. RecyclingThe total MSW recycled was more than 69 million tons, with paper and paperboard accounting for approximately 67 percent of that amount. Metals comprised about 13 percent, while glass, plastic and wood made up between 4 and 5 percent. Measured by tonnage, the most-recycled products and materials in 2018 were corrugated boxes (32.1 million tons), mixed nondurable paper products (8.8 million tons), newspapers/mechanical papers (3.3 million tons), lead-acid batteries (2.9 million tons), major appliances (3.1 million tons), wood packaging (3.1 million tons), glass containers (3 million tons), tires (2.6 million tons), mixed paper containers and packaging (1.8 million tons) and selected consumer electronics (1 million tons). Collectively, these products accounted for 90 percent of total MSW recycling in 2018. Check out our Reduce, Reuse, Recycle web area for more information on recycling. Composting/Other Food ManagementThe total MSW composted was 25 million tons. This included approximately 22.3 million tons of yard trimmings (more than a five-fold increase since 1990) and 2.6 million tons of food waste (4.1 percent of generation of wasted food). Other methods of food management were estimated for the first time in 2018. In 2018, 17.7 million tons of food (28.1 percent of generation of wasted food) was managed through animal feed, co-digestion/anaerobic digestion, bio-based materials/biochemical processing, donation, land application and sewer/wastewater treatment. Combustion with Energy RecoveryCheck out our Energy Recovery from the Combustion of Municipal Solid Waste (MSW) page for more information. In 2018, 34.6 million tons of MSW were combusted with energy recovery. Food made up the largest component of MSW combusted at approximately 22 percent. Rubber, leather and textiles accounted for over 16 percent of MSW combustion. Plastics comprised about 16 percent, and paper and paperboard made up about 12 percent. The other materials accounted for less than 10 percent each. LandfillingIn 2018, about 146.1 million tons of MSW were landfilled. Food was the largest component at about 24 percent. Plastics accounted for over 18 percent, paper and paperboard made up about 12 percent, and rubber, leather and textiles comprised over 11 percent. Other materials accounted for less than 10 percent each. Trends – 1960 to TodayIn 2018, the amount of MSW generated was 292.4 million tons. The amount of MSW recycled was 69.0 million tons and the amount composted was 24.9 million tons. About 17.7 million tons of food were managed by other methods. The amount of MSW combusted with energy recovery was 34.6 million tons, while the amount of MSW sent to landfills was 146.2 million tons. Presented below are details of these trends:
*MSW generation rose considerably from 2017 to 2018 mainly because EPA enhanced its food measurement methodology to more fully account for all the ways wasted food is managed throughout the food system. Generation TrendsThe 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 67.4 million tons in 2018. Generation of yard trimmings and food waste has increased since 2000. Generation of other material categories fluctuates from year to year, but overall MSW generation increased from 1960 to 2005, with the trend reversing from 2005 to 2010, and rising again from 2010 through 2018. Recycling and Composting TrendsIn percentage of total MSW generation, recycling (including composting) did not exceed 15 percent until 1990. Growth in the recycling rate was significant over the next 15 years, spanning until 2005. The recycling rate grew more slowly over the last few years. The 2018 recycling rate was 32.1 percent. The recycling and composting rates (as a percentage of generation) of the below materials in MSW has mostly increased over the last 58 years. Read over the table below for examples. Recycling and composting as a percentage of generation
"Neg." means less than 5,000 tons or 0.05 percent. The rate of yard trimmings composting was negligible in 1980, rose to 12 percent in 1990 and 52 percent in 2000. In 2005 it was 62 percent, in 2017 it was 69 percent, and in 2018 it was 63 percent. Food composting was negligible in 1990, rose to 2.2 percent (680,000 tons) in 2000, 5.3 percent (2.1 million tons) in 2015 and 6.3 percent (2.6 million tons) in 2017. In 2018 the food composting rate was 4.1 percent (2.6 million tons). Due to a change in methodology, there was an increase in the wasted food generation estimate between 2017 and 2018, which resulted in a lower composting rate even though the tons composted remained the same from 2017 to 2018. Other Food Management TrendsOther food management pathways, estimated for the first time in 2018, was 17.7 million tons (28.1 percent of wasted food generation). These management pathways include animal feed, codigestion/anaerobic digestion, bio-based materials/biochemical processing, donation, land application and sewer/wastewater treatment. Check out the Food: Material-Specific Data web page. Recycling, Composting and Other Food Management Trends Specific to 2015-2018Included in the generation number are the almost 94 million tons of MSW recycled and composted and an additional 17.7 million tons of other food management in 2018. The following provides a detailed breakdown of the numbers:
Listed here are the recycling or composting rates for three categories of materials, including paper and paperboard, yard trimmings, and food:
Greenhouse Gas BenefitsEPA’s report Sustainable Materials Management: The Road Aheadserves as the foundation for the EPA SMM Program. The recommendations and analytical framework under the Road Ahead encourage the consideration of multiple environmental benefits when developing materials management strategies. Currently, EPA has a tool for estimating greenhouse gas reductions resulting from sustainable materials management – the Waste Reduction Model (WARM). This section shows those GHG reduction environmental benefits. The Agency is developing additional tools to provide information on other environmental benefits and will include these tools and data as they become available. In 2018, the recycling, composting, combustion with energy recovery and landfilling of MSW saved over 193 million metric tons of carbon dioxide equivalent (MMTCO2E). This is comparable to the emissions that could be reduced from taking almost 42 million cars off the road in a year. Paper and paperboard recycling, at about 46 million tons, resulted in the largest portion of the total MSW reduction over 155 MMTCO2E in 2018. This reduction is equivalent to removing over 33 million cars from the road for one year. The energy and GHG benefits of recycling, composting, combustion with energy recovery and landfilling shown in the table below are calculated using the WARM methodology. The estimates of MMTCO2E are calculated using WARM, and identify not only the environmental benefits of recycling, composting and combustion for energy recovery, but also the benefit of not landfilling materials. Numbers in parentheses indicate a reduction in either greenhouse gases or vehicles, and therefore represent environmental benefits. Greenhouse Gas Benefits Table(The numbers in the Recycled, Composted, Combustion with Energy Recovery and Landfilled columns are listed by weight of material* in millions of tons)
*Includes material from residential, commercial and institutional sources (except not industrial process waste). These calculations do not include an additional 24.9 million tons of MSW that could not be addressed in the WARM model (including 17.7 million tons from food waste managed by means outside of the scope of the WARM model). MMTCO2E is million metric tons of carbon dioxide equivalent. Details might not add to totals due to rounding. Source: WARM model Version 15. Number of cars taken off the road/year was calculated using the Greenhouse Gas Equivalency Calculator, updated March 2020.
