SEEING THE FULL PICTURE 1
-------
IN SOME COMMUNITIES across the United States, recycling is a cost-
effective way to manage municipal solid waste. The experience of
Madison, Wisconsin (population 201,000), for example, illustrates the
economic benefits curbside recycling can provide midsized U.S. cities.
In 8 years, the city more than tripled its diversion of residential solid waste
while also decreasing the net annual cost of solid waste services from $158
per household to $139. A recycling rate (including composting) of 49 per-
cent reduced the riumber of garbage routes needed and helped hold land-
fill tipping fees in check.'
As solid waste managers take advantage of various cost-saving methods
for collecting residential solid waste and recyclables, the business of
municipal solid waste collection will become even more cost-effective.
Successful strategies include changing collection frequency, introducing
automated collection equipment, and improving routing design. Dozens of
local governments and haulers across the country have demonstrated that
these and other strategies can have dramatic impacts on the bottom line
while improving the quality of service delivery.2
Mesa, Arizona (population 314,000), is one city that saved money by
recycling. When the city integrated curbside recycling into its solid waste
management system, it was able to reduce the number of garbage pick-ups
, from twice per week to just once. To reduce costs further, the city also
upgraded its fleet of collection trucks (thus reducing labor and mainte-
nance costs), streamlined collection routes, and initiated staff productivity

and cost tracking systems. Mesa's efforts resulted in a net annual cost say-
ings of more than $650,OQ0.3 In a similar fashion, Loveland, Colorado
(population 44,000), enfoyed an estimated net savings of $200,000 per
year by purchasing specially designed dual-collection trucks that allow the
collection of solid waste and recyclables in the same truck.4
ECONOMIC DEVELOPMENT
Advances in the collection of solid waste and recyclables are only one piece
of recycling's economic success. Recycling also has made a vital contribution
to job creation and economic development. Recycling creates or expands busi-
nesses that collect, process, and broker recovered materials as well as compa-
nies that manufacture and distribute products made with recovered materials.
Numerous studies have documented the billions of dollars invested and the
thousands of jobs created by recycling. A 1995 recycling employment study
for the state of North Carolina, for instance, documented that recycling activi-
ties support more than 8,800 jobs in the state, most of which are in the pri-
vate sector. The study also found that recycling was a net job creator—for
every 100 jobs created by recycling only an estimated 13 were lost in solid
waste collection and disposal and virgin material extraction within the state.5
In addition, a study of 10 northeastern states found that processing and
remanufacturing recyclable materials in the region added more than $7.2
billion to the value of the materials. According to the study, recycling
employed more than 103,000 people, 25 percent in materials processing
(i.e., sorting and intermediate processing facilities) and 75 percent in man-
ufacturing (see graph below).6 These studies show that thousands of com-
munities are realizing benefits from recycling far beyond diverting materi-
als from landfills and incinerators.

RECYCLING INDUSTRIES
Industries that use recovered materials are a vital and growing sector of
our economy. Today's recycling programs provide manufacturers with
many of the raw materials they need to operate more efficiently. Our grow-
ing supply of recyclables keeps manufacturing industries more competitive
and more sustainable.
The increased use in recent years of "minimills" by steel producers illustrates
the importance recovered materials hold for some industries. Steel minimills
utilize a manufacturing process that requires virtually 100 percent recovered
scrap steel as the raw material. Indeed, all steel prod-
ucts manufactured in the United States, including
bridge components, road signs, and construction
materials, are made from some recy-
cled steel. Steel can recycling, in con- .

Currently, the supply of commercial '.

fiber demands of paper mills. - -^-. - : •
Consequently, the use of recovered — t,
paper at domestic mills is growing more than
twice as fast as the use of virgin wood fiber.8 In
this decade alone, the U.S. paper industry will spend more than $10 bil-
lion on new or expanded recycled paper mills.9 The industry will need
recovered paper from both commercial and municipal recycling programs
to supply these mills with raw materials. According to one industry expert,
recovered paper will account for 47 percent of global papermaking fiber
by2010.10
RECYCLABLES AS COMMODITIES
In 1995, the United States recovered 56 million tons of materials from the
municipal solid waste stream for recycling (including composting)." Based
on average national price information for May 1996 to April 1997, these
recovered materials have a total market value of approximately $3.6 bil-

lion,12 As shown in

aluminum cans and
corrugated boxes have
the highest market
values, at $1 billion
and $940 million,
respectively. As these
numbers show, the
materials collected in
recycling programs are
not "garbage" or
"waste"—they are
valuable commodities
that represent an es-
sential component of
today's marketplace.
As with any busi-
ness, recycling is sub-
ject to the cyclical highs and lows of free market supply and demand.
While there have been periods when prices for recyclables were relatively
low, they have been consistent with historical trends for both virgin and
recovered materials. In fact, for all markets, prices are normally unstable
during the early stages of development. Some recovered material markets,
such as plastics, are relatively young and will continue to mature and sta-
bilize with the expanded use of recovered materials in manufacturing and
increased purchases of products with recycled content.
An innovative mechanism for buying and selling recovered materials
that is intended to stabilize markets is the Chicago Board of Trade
Recyclables Exchange . Recycling made headlines
and moved into the league of soybeans and porkbellies with the launch of
this Internet-based system in 1995. EPA helped establish the Recyclables
Exchange in conjunction with a group of partners from around the coun-
try. This centralized marketplace is designed to bring the same level of
price stability and quality standards to recovered materials that has
occurred with other long-standing commodities traded every day on the
floor of other Chicago Board of Trade exchanges.

helps reduce or eliminate the pollution associated with tie first two stages
of a product's development: material extraction and processing. Mineral
extracting and processing often pollute air, land, and water with toxic
materials. In addition, both mining and processing operations require
energy—that is, the burning of fuels such as coal, oil, and natural gas.
When burned, these fuels release pollutants, such as sulfur dioxide, nitro-
gen oxide, and carbon monoxide, into the air.13
When products are,made using recovered rather than virgin materials,
less energy is used during manufacturing and, consequently, fewer pollu-
tants are emitted. Studies show that less energy is needed to manufacture
products from recovered materials than from virgin materials. As shown in
the graph on page 9, manufacturing products from recovered materials can
reduce the amount, of energy needed by as much as 94 percent.14
EXPANDING THE ENVIRONMENTAL VIEW
-------
A recent analysis of several studies concluded that the environmental
impacts of recycled-content products are less than those of virgin products
when the two are compared ovefjueir entire life cycles. The analysis found
that when compared to a system based on the use of virgin materials and
landfilling or incineration, recycling and manufacturing products from
recovered materials results in a net reduction in 10 major categories of air
pollutants (aldehydes, ammonia, carbon dioxide, carbon monoxide, hydro-
carbons, methane, nitrogen oxides, other organics, particulates, and sulfur
oxides) and 8 major categories of water quality indicators and water pollu-
tants (biochemical oxygen demand, chemical oxygen demand, dissolved
solids, iron, metal ions, oil, sulfuric acid, and suspended solids). Using
recovered materials also generates less solid waste, whether measured by
weight or volume.11

MITIGATING GLOBAL CLIMATE CHANGE
In reducing air and water pollution and saving energy, recycling offers an impor-
tant environmental benefit: it reduces emissions of the greenhouse gases, such
as carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons, that con-
tribute to global climate change. There is a growing international consensus
that a link exists between these gases and a rise in average global temperatures.
A rise in global temperatures will increase the frequency and severity of ex-
treme weather events. In the United States alone, the number of blizzards and
heavy rainstorms has jumped 20 percent since 1900, making events that once
occurred an average of once every 100 years much more frequent. Globally,
economic damages from weather-related disasters during the 1990s have
exceeded $200 billion—four times the total losses reported during the 1980s.1"
The manufacture and distribution of products, and the subsequent manage-
ment of the solid waste they create, contribute to the emission of greenhouse
gases. Recycling (.including composting) helps reduce greenhouse gas emis-
sions by (1) decreasing the energy needed to make products from virgin
materials (and thereby reducing the burning of fossil fuels), (2) reducing emis-
sions from incinerators and landfills, which are the major source of methane

PROTECTING
BIODIVERSITY
Extracting fewer virgin
materials not only
decreases greenhouse gas
emissions, it also prevents
the disruption of land
areas that are home to a
wide variety of plant and
animal species. As a result
of human activities,
including the acquisition
of virgin materials, species of plants and animals are now vanishing 100 to
1,000 times faster than would be expected in the absence of such activi-
ties.18 Such diminution of the earth's biodiversity has a substantial human
cost because wild species and natural ecosystems provide numerous bene-
fits to people. Some economists, for example, estimate that the lost phar-
maceutical value from plant species extinctions in the United States alone
is almost $12 billion.19 By reducing the land disturbance and pollution
associated with virgin materials extraction, recycling helps stop the degra-
dation of the earth's ecosystems.
