Introduction
U.S. Environmental Protection Agency (EPA) has collected and reported data on the generation and disposition of
waste in the United States for more than 30 years. We use this information to measure the success of waste
reduction and recycling programs across the country and characterize our national waste stream. These facts
and figures are current through calendar year 2014.
In 2014, in the United States, about 258 million tons (U.S. short tons unless
specified) of municipal solid waste (MSW) were generated. Over 89 million
tons of MSW were recycled and composted, equivalent to a 34.6 percent
recycling rate (see Figure 1 and Figure 2). In addition, over 33 million tons
of MSW were combusted with energy recovery and 136 million tons were
landfilled (see Table 1).
Recycling and composting of MSW results in greenhouse gas (GHG) emissions
reduction. In 2014, the 89 million tons of MSW recycled and composted
provided an annual reduction of over 181 million metric tons of carbon dioxide equivalent (MMTC02E)
emissions, comparable to the annual emissions from over 38 million passenger cars.1
As the title for the annual report suggests, EPA is thinking beyond waste. Sustainable Materials Management
(SMM) refers to the use and reuse of materials in the most productive and sustainable way across their entire
life cycle. SMM conserves resources, reduces waste, slows climate change and minimizes the environmental
impacts of the materials we use.

The sustainable management of natural capital has become increasingly important with expanding demand
for finite resources on the global scale. For economic growth to reliably continue, responsible use of natural
resources must consider the environmental and human health impacts. Considering the entire life cycle of the
needed materials, businesses are able to reduce environmental and human health risk while enhancing and
sustaining their value proposition.
According to the United Nations Environment Programme, International Resources Panel (UNEP IRP), "data
suggest that while long-run relative decoupling of material extraction from GDP [gross domestic product] can
be observed at a global level, this relative decoupling is not sufficient to prevent a persistent increasing trend in
absolute resource extraction. Indeed, in contrast to the long-run relative decoupling trend over the 20th century,
recent years' data suggest that resource extraction has begun to increase at a faster rate than GDP, suggestive
of 'recoupling'."2 In a subsequent report, the UNEP IRP expands upon these observations: "the material
intensity of the world economy has been increasing for the past decade, driven by the great acceleration that
has occurred since the year 2000. Globally, more material per unit of GDP is now required. Production has
shifted from very material-efficient countries to countries that have low material efficiency, resulting in an
overall decline in material efficiency."3

Trends in Municipal Solid Waste in 2014
Our trash, or MSW, is comprised of various items Americans
commonly throw away after being used. These items include
packaging, food, yard trimmings, furniture, electronics, tires
and appliances. MSW does not include industrial, hazardous or
construction waste.
In 2014, about 66.4 million tons of MSW were recyled, 23
million tons were composted, 33.1 million tons were combusted
with energy recovery and 136 million tons were landfilled.
In 2014, the rate of lead-acid battery recycling was about 99 percent (2.81 million tons). The rate of corrugated box
recycling was over 89 percent (27.3 million tons), and over 61 percent (21.1 million tons) of yard trimmings were
composted (see Figure 3). About 135.9 million tons of MSW (52.6 percent) were landfilled in 2014 (see Figure 4).
Three materials had composting or recycling rates that rose from 2013 to 2014 — yard trimmings, selected
consumer electronics and food. In 2014, the rate of yard trimmings composting was 61.1 percent (21.1 million
tons), up from 60.2 percent (20.6 million tons). The rate of yard trimmings composting was 51.7 percent in the
year 2000. In 2014, the rate of selected consumer electronics recycling was 41.7 percent (1.4 million tons) up from
37.8 percent in 2013 (1.3 million tons).4 This was a further increase from the year 2000, when selected consumer
electronics were recycled at 10.0 percent. In 2014, the rate of food composting was 5.1 percent (1.94 million tons),
up from 5.0 percent in 2013 (1.84 million tons).5 The rate of food composting was 2.2 percent in the year 2000.
Sources of MSW
Sources of MSW include residential waste (including waste from multi-family housing) and waste from
commercial and institutional locations, such as businesses, schools and hospitals.
Over the last few decades, the generation, recycling, composting, combustion with energy recovery and landfilling of
MSW changed substantially. Solid waste generation per person per day peaked in 2000. The 4.4 pounds per person
per day in 2014 is about the same as in 2013, and is one of the lowest rates since before 1990. The recycling and
composting rate has increased from less than 10 percent of generated MSW in 1980 to over 34 percent in 2014.
Combustion with energy recovery increased from less than two percent of generation in 1980 to 12.8 percent in 2014.
Landfilling of waste decreased from 89 percent in 1980 to under 53 percent in 2014.
Recycling and composting did not exceed
15 percent of total MSW generation until
1990. Growth in the recycling rate was
significant over the next 15 years. Over the
last five years, the recycling growth rate has
leveled off.

Analyzing MSW
EPA analyzes waste by material, such as plastics, or paper and paperboard, as well as 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).
Nationally, in 2014, Americans recycled and composted over 89 million tons of municipal solid waste. This provides
an annual reduction of more than 181 MMTCO:,E, comparable to the annual GHG emissions from over 38 million
passenger vehicles.
Materials in MSW
Total MSW generation in 2014 was 258.5 million tons. Figure 5 shows the breakdown of MSW generation
by material. Organic materials such as paper and paperboard, yard trimmings and food continued to be the
largest component of MSW. Paper and paperboard accounted for over 26 percent, and yard trimmings and food
accounted for another 28.2 percent. Plastics comprised about 13 percent of MSW; rubber, leather, and textiles
accounted for over nine percent; and metals made up nine percent. Wood followed at over six percent, and glass
over four percent. Other miscellaneous wastes made up approximately three percent of the MSW generated in
2014.
Total MSW recycling and composting in 2014 was over 89 million tons. Figure 6 shows that in 2014, paper and
paperboard accounted for about 50 percent of all recycling, yard trimmings accounted for over 23 percent while
food accounted for another two percent. Metals comprised about nine percent and glass, plastic and wood
made up about three percent each. Other miscellaneous materials made up about six percent of MSW recycling
and composting.
The highest recyling and composting rates were achieved in paper and paperboard, yard trimmings and metals.
More than 64 percent of the paper and paperboard generated was recycled. Over 21 million tons of yard
trimmings were composted (almost a five-fold increase since 1990). In 2014,34 percent of metal was recycled.
Recycling and composting these three materials alone kept over 28 percent of generated MSW out of landfills.
In 2014,33 million tons of MSW were combusted with energy recovery. Food made up the largest component
of MSW combusted (over 21 percent). Rubber, leather and textiles accounted for over 17 percent of MSW
combustion. Plastics comprised about 15 percent; and paper and paperboard made up over 14 percent. The
other materials accounted for less than 10 percent each (see Figure 7).
In 2014, about 136 million tons of MSW were landfilled. Food was the largest component (over 21 percent).
Plastics accounted for over 18 percent, paper and paperboard made up over 14 percent and rubber, leather and
textiles comprised over 10 percent. Other materials accounted for less than 10 percent each (see Figure 8).
Table 1 provides recycling, composting, combustion with energy recovery and landfill amounts and rates (as
percent of generation) for all materials in 2014.

Products in MSW
The breakdown of the 258 million tons of MSW generated in 2014 by product category follows. Containers and
packaging made up the largest portion of MSW generated: 29.7 percent, or over 76 million tons. Nondurable
and durable goods each made up about 20 percent (over 52 million tons) each. Food made up 14.9 percent
(38.4 million tons), yard trimmings made up 13.3 percent (34.5 million tons) and other wastes made up 1.5
percent (4 million tons).
Table 2 shows the generation, recycling, composting, combustion with energy recovery and landfilling
of materials in the product categories, by weight and as percent of generation. This table shows that the
recycling of containers and packaging was the highest of the four product categories, with over 51 percent
of the generated materials recycled. Paper products, steel and aluminum were the most recycled materials by
percentage in this category. Over 75 percent of paper and paperboard containers and packaging was recycled.
Over 72 percent of steel packaging (mostly cans) was recycled. The recycling rate for aluminum packaging was
almost 39 percent, including over 55 percent of aluminum beverage cans.
Over 32 percent of glass containers was recycled, while over 26 percent of wood packaging (mostly wood
pallets) was recycled. Almost 15 percent of plastic containers and packaging was recycled—mostly from soft
drink, milk and water bottles. Plastic bottles were the most recycled plastic products. Polyethylene terephthalate
(PET) bottles and jars were recycled at over 31 percent. Recycling of high density polyethylene (HDPE) natural
(white translucent) bottles was estimated at over 29 percent (see 2014 data tables).
Nondurable goods generally last less than three years. Overall recycling of
nondurable goods was about 33 percent in 2014. Newspapers/mechanical papers Every ton of office
and other paper products were the most recycled nondurable goods. Newspapers/ paper recycled can
mechanical papers include newspapers, directories, inserts, and some advertisement save .
and direct mail printing. Sixty-eight percent of newspapers/mechanical papers were
recycled. Collectively, the recycling of other paper products such as office paper
and magazines was over 44 percent in 2014. Clothing, footwear and other textile
products are included in the nondurable goods category. These products were
recycled at a rate of over 17 percent.
Overall, 18 percent of durable goods was recycled in 2014. Due to the high rate of lead recycling from lead-acid
batteries, nonferrous metals (other than aluminum) had one of the highest recycling rates. With an almost 99
percent recycling rate, lead-acid batteries continued to be one of the most recycled products. Recycling of steel
in all durable goods was over 27 percent, with high rates of recycling from appliances and other miscellaneous
items. Recycling of selected consumer electronics (ranging from TVs, computers and cell phones to fax machines)
was over 41 percent (see Figure 3).
Measured by percentage of generation, products with the highest
recycling rates in 2014 were lead-acid batteries (98.9 percent), Recycling just one ton of aluminum
corrugated boxes (89.5 percent), steel cans (70.7 percent), newspapers/ cans conserves more than 152
mechanical papers (68.2 percent), yard trimmings (61.1 percent), major million Btu, the equivalent of 1,024
appliances (58.3 percent), aluminum cans (55.1 percent), mixed paper gallons ofgasoline or 21 barrels of

Combustion with Energy Recovery
Most of the MSW combustion in the U.S. incorporates recovery of an energy product (generally steam or
electricity).
¦ In 2014, about 33.1 million tons (12.8 percent) of materials were combusted for energy recovery (see
Table 3).
¦ From 1990 to 2000, the quantity of MSW combusted with energy recovery increased over 13 percent to
about 34 million tons.
¦ MSW combustion for energy recovery has decreased from about 34 million tons in 2000 to 33.1 million
tons in 2014.
Landfilling of MSW
While the number of U.S. landfills has steadily declined over the years, the average landfill size has increased.
At the national level, landfill capacity appears to be sufficient for our current practices—although it is limited
in some areas.
¦ Since 1990, the total amount of MSW going to landfills dropped by 9.3 million tons, from 145.3 million to
136 million tons in 2014 (see Table 3).
¦ The net per capita 2014 landfilling rate (after recycling, composting and combustion with energy
recovery) was 2.3 pounds per day, lower than the 3.2 per capita rate in 1990 (see Table 4).
¦ From 1985 to 1995 there was a rapid rise in the cost to manage MSW going to landfills, followed by a
steady decrease from 1995 to 2004. Since 2004, there has been a steady increase in landfill tipping fees
(see Figure 9). The tipping fees are expressed in constant 2014 dollars.

MSW Generation and Household Spending
Over the years, the change in the amount of MSW generated typically imitated trends in how much money
U.S. households spent on goods and services. Personal Consumer Expenditures (PCE) measure U.S. household
spending on goods and services such as food, clothing, vehicles and recreation services. PCE accounts for
approximately 70 percent of U.S. Gross Domestic Product, a key indicator of economic growth. PCE adjusted
for inflation is referred to as real PCE.This metric is more useful in making comparisons over time because it
normalizes the value of a dollar by considering how much a dollar could purchase in the past versus today.
Figure 10 explores the relationship between MSW generated and real PCE since 1960.
Figure 10 is an indexed graph showing the relative changes in real PCE, MSW generated and MSW generated
per capita over time. It is indexed to allow all three of these metrics to be shown on the same graph and
compare their relative rates of change since 1960. The indexed value indicates the change in the value of the
data since 1960. For example, if for a given year the value is three, then the data value for that year would be
three times the 1960 value. In this case, if the 1960 value was 200, then the resulting year's value would be
600. The 2014 MSW per capita generation indexed value is 1.7, which means MSW per capita generation has
increased by 70 percent since 1960.
Figure 10 shows that real PCE has increased at a faster rate than MSW generation, and the disparity has become
even more distinct since the mid 1990s. This metric indicates the amount of MSW generated per dollar spent
is falling. In other words, the U.S. economy has been able to enjoy dramatic increases in household spending
on consumer goods and services without the societal impact of similarly increasing MSW generation rates. This
figure also shows that the MSW generated per capita leveled off in the early-to-mid 2000s and has since fallen.
This is important because as population continues to grow, it will be necessary for MSW generated per capita to
continue to fall to maintain or decrease the total amount of MSW generated as a country.

Construction and Demolition (C&D) Debris
Generation Results
C&D debris is a type of waste which is not included in MSW. Materials included in C&D are steel, wood products,
drywall and plaster, brick, clay tile, asphalt shingles, concrete and asphalt concrete. These materials are used in
building as well as road and bridge sectors. The generation estimate represents C&D amounts from construction,
renovation and demolition activities for buildings, roads and bridges.
in 2014, 534 million tons of C&D debris were generated. Figure 11 shows the 2014 generation composition for
C&D. Concrete was the largest portion (70 percent), followed by asphalt concrete (14 percent). Wood products
made up seven percent and the other products accounted for nine percent combined, The 2014 generation
estimates are presented in more detail in Table 6. As shown in Figure 12, demolition represented over 90 percent
of total C&D debris generation as opposed to construction which represented under 10 percent.

Table 7 displays the amount of C&D debris generation from buildings, roads and bridges and other structures
for each material. The other structures category includes communication, power, transportation, sewer and
waste disposal, water supply, conservation and development and manufacturing infrastructure. In 2014, roads
and bridges contributed significantly more to C&D debris generation than buildings and other structures, and
concrete made up the largest share of C&D debris generation for all three categories.8

a Wood consumption in buildings also includes some lumber consumed for the construction of other structures. Data were not available to allocate lumber
consumption for non-residential and unspecified uses between buildings and other structures except for railroad ties. Since non-residential buildings such
as barns, warehouses and small commercial buildings are assumed to consume a greater amount of lumber than other structures, the amount of lumber for
construction remaining after the amount for railroad ties is split out, is included in the buildings source category.
b Steel consumption in buildings also includes steel consumed for the construction of roads and bridges. Data were not available to allocate steel consumption
across different sources, but buildings are assumed to consume the largest portion of steel for construction.
Thinking Beyond Waste
EPA is helping change the way our society protects the environment and conserves resources for future
generations by thinking beyond recycling, composting, combustion with energy recovery and landfilling.
Building on the familiar concept of Reduce, Reuse, Recycle, the Agency is employing a systemic approach
that seeks to reduce materials use and associated environmental impacts over their entire life cycle, called
sustainable materials management (SMM). This process starts with extraction of natural resources and material
processing through product design and manufacturing, then the product use stage, followed by collection/
processing and final end of life. By examining how materials are used throughout their life cycle, an SMM
approach seeks to use materials in the most productive way with an emphasis on using fewer materials and
products, reducing toxic chemicals and environmental impacts throughout the material's life cycle and assuring
we have sufficient resources to meet today's needs and those of the future. Data on MSW generation, recycling,
composting, combustion with energy recovery and landfilling is an important starting point for the full SMM
approach.

Resources
The data 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. EPA recognizes that there are several approaches to
measuring material flows (e.g. volume). To be consistent, EPA reports the materials quantities in tons in the
current fact sheet but will continue to explore options for alternative measurement quantifications to describe
materials management in the U.S.
EPA has consistently used materials flow analysis (MFA) to allow for comparison of data over the last three
decades. EPA recognizes this methodology differs from other methodologies that also estimate generation
of MSW and other waste data. EPA will continue to work with stakeholders to identify methodologies and
additional publically available data to improve our national understanding of materials flow in the U.S.
The following provides an example of how the materials flow methodology is used in the fact sheet. 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 plus recycled paper exported, instead of counting paper collected for
recycling 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, composted, combusted with energy recovery and landfilled. Other sources
of data, such as waste characterizations and research reports performed by governments, industry or the press,
supplement these data. The data on C&D debris generated summarized in this report is also developed using a
materials flow methodology.
The benefits of MSW recycling and composting, such as elimination of GHG emissions, are calculated using
EPA's WARM methodology. WARM calculates and totals GHG emissions of baseline and alternative waste
management practices including source reduction, recycling, composting, combustion and landfilling. The model
calculates emissions in metric tons of carbon equivalent (MTCE), metric tons of carbon dioxide equivalent
(MTC02E) 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 assessment methodology. Please see:
https://www.epa.gov/warm.
The 2014 data tables and Summaries of the MSW characterization methodology and WARM are available on the
EPA website along with information about waste reduction, recycling and sustainable materials management.
