               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.

Trends in  Municipal Solid Waste

in 2007
Our trash, or municipal solid waste (MSW), is made up
of the things we commonly use and then throw away.
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.

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).

Significant amounts of materiai from each category were
recycfed or composted in 2007. 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.

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).

   Disposing 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, 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.

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.
