Chapter 6. Designing a New Materials Economy

(W.W. Norton & Co., NY: 2001).
In March 2001, the Fresh Kills landfill,
the local destination for New York City's daily output of 12,000
tons of garbage, was permanently closed. Now the garbage is hauled
to distant sites in New Jersey, Pennsylvania, and Virginiasome
of them more than 480 kilometers (300 miles) away. Assuming a load
of 20 tons of garbage for each of the tractor-trailers that are
used for the long-distance hauling, some 600 rigs are needed to
remove garbage from New York City each day. These tractor-trailers
form a convoy nearly 15 kilometers (9 miles) long, impeding traffic,
polluting the air, and raising carbon emissions. This daily convoy
of trucks leaving the city led Deputy Mayor Joseph J. Lhota, who
supervised the Fresh Kills shutdown, to say that getting rid of
the city's trash is now "like a military-style operation on a daily
basis."1
What is happening in New York will occur in other cities if they
also fail to adopt comprehensive recycling programs. Instead of
focusing efforts on reducing garbage as the Fresh Kills landfill
was filling, the decision was made to simply haul the garbage to
more remote sites. Even a simple measure like recycling all its
paper could shorten the daily convoy leaving the city by 187 tractor-trailers
or 4.5 kilometers (2.8 miles).2
Fiscally strapped local communities are willing to take the garbage
if New York pays enough. Some see it as a bonanza. For the state
governments, however, that have to deal with the traffic congestion,
noise, increased air pollution, and complaints from nearby communities,
this arrangement is not so attractive. The Governor of Virginia
wrote to New York Mayor Rudy Giuliani complaining about the use
of Virginia as a dumping ground. "I understand the problem New York
faces," he noted. "But the home state of Washington, Jefferson and
Madison has no intention of becoming New York's dumping ground."
Whether New York can continue to dump its garbage in others states
over the long term remains to be seen.3
Earlier periods in human history were marked by the material that
distinguished the erathe
Stone Age and the Bronze Age, for example. Our age is simply the
Material Age, an age of excess whose distinguishing feature is not
the use of any particular material, but the sheer volume of materials
consumed.
Worldwide, we process or use 26 billion tons of materials each year,
including 20 billion tons of stone, gravel, and sand used for road
building and construction; over 1 billion tons of iron ore processed
for steelmaking; and 700 million tons of gold ore for extracting
gold. From forests, we take 1.7 billion tons of wood for fuel, roughly
1 billion tons for wood products, and just over 300 million tons
for manufacturing paper. To obtain phosphorus and potassium to replace
the nutrients that our crops remove from soils, we annually mine
139 million tons of phosphate rock and 26 million tons of potash.4
Each of the earth's 6.1 billion inhabitants uses on average 137
kilograms (300 pounds) of steel per year in automobiles, household
appliances, buildings, and other products. This means that each
of us consumes nearly double our body weight in steel each year.
Producing that steel means processing more than 340 kilograms of
iron ore per person.5
The scale of the materials economy is far larger than most of us
ever imagine, simply because we come in contact with only the final
productwe
see, for example, the steel in our car or refrigerator, but not
the tons of ore from which it was extracted, or we see the paper
in our newspapers and stationery, but not the stack of logs from
which it was processed.
The production of some seemingly innocuous items, such as gold jewelry,
can be incredibly destructive. For example, the gold rings exchanged
by couples during weddings require the processing of tons of ore,
most likely by cyanide leaching. Worldwatch researcher John Young
calculated that to create a pair of gold wedding rings, the ore
processed is the equivalent of a hole in the ground that is 10 feet
long, 6 feet wide, and 6 feet deep. Fortunately for the newlyweds,
this hole is in someone else's backyard. So, too, is the cyanide
used to separate the gold from the ore.6
All the figures just cited are global averages, but the use of materialslike
that of energy and foodvaries
widely among societies. For example, steel production per person
in the United States totals 352 kilograms annually; in China, it
is 98 kilograms, and in India, just 24 kilograms.7
The processing of vast quantities of ore to produce metals is polluting
local air and water. The energy use, the physical disruption of
the land, and the pollution associated with processing ever growing
quantities of ore are becoming less and less acceptable.
The sheer size of the materials economy is not only physically disruptive,
it also uses vast quantities of energy. In the United States, the
steel industry alone uses as much electricity as the country's 90
million homes.8
Building an eco-economy depends on restructuring the materials economy
becauselike
the energy economyit
is in conflict with the earth's ecosystem. Architect William McDonough
and chemist Michael Braungart talk about doing this. They describe
an economy that is regenerative rather than depletive, one whose
products "work within cradle-to-cradle life cycles rather than cradle-to-grave
ones." In effect, this redesign means replacing the current linear
flow-through model with a circular model that emulates nature, one
that closes the loop. It means replacing mining industries with
recycling industries, a step that will allow a mature, industrial
economy with a stable population to live largely on the materials
already in use.9
