Introduction
Garbage
101
Garbage
is a dirty business. And as anyone who has ever lived near or visited
a landfill will tell you, it is also a smelly business. In the U.S.,
a country that is blessed with many wide-open spaces, garbage has
always been a "somebody else's" business, as well. For most of our
history, we have treated garbage the same way: dump it somewhere
away from our towns and cities. For cities near the ocean, this
has meant dumping it at sea, or possibly close to shore if land
was being reclaimed. For inland cities, this has resulted in burying
it in open pits. As long as the citizens of the cities or towns
did not have to see it, there was no problem.
As cities and towns grew, and as the products that went into the
waste stream became more toxic, concern began to escalate. The growing
cities meant that people were moving out closer to the dumps, and
that the amount of waste that was going to the dump was expanding.
The increasing toxicity of products going into the dumps meant that
local groundwaters were becoming polluted with leachate that had
passed through the landfill. With growing legal issues and tougher
environmental laws on pollution of groundwater, changes in how garbage
is disposed of have been taking place over the last several decades.
A modernized landfill, with barriers to leachate and methane recovery
systems, is a vast improvement to the old style dump.
Recycling
But even a modernized landfill does not get to the heart of the
matter. As long as people continue to produce garbage at the rate
that they are, we are going to continue to run out of places to
put it. In high-density population centers along the northestern
seaboard, this situation is becoming more critical every day. Nothing
better epitomizes the situation in this area than the barge
full of trash from Long Island in 1987 that could not find any
takers. After a 3,000-mile trip down the eastern seaboard and into
Mexico, the barge had to be returned to New York because no other
city or state would allow the shipment to be dumped in their landfill.
While the situation in Long Island has improved, other municipalities
find themselves in similar situations today.
The solution to this problem of what to do with waste is rather
simple: reduce, reuse, and recycle. This simplistic mantra is really
quite powerful, but it takes a change in lifestyle. Usually, the
change only comes about when the situation becomes critical. In
high population density areas such as Japan and certain countries
in Europe, systems of laws and fee penalties exist to force the
citizens to limit how much garbage they throw away. This causes
people to reconsider how much packaging is involved when they buy
something and to recycle as much of their waste as possible. This
situation is beginning to occur in the U.S., as well. As we can
see in the Long Island garbage barge story, the shutting down of
all landfills in 1990 and the refusal of other communities to take
their garbage forced the local system into greater recycling (about
35% of the waste is now recycled).

Wise
After reading through these and any other sites that you might find,
answer the following questions
- The EPA website shows that the U.S. went from 2.7 pounds of
solid waste per person per day in 1960 to 4.6 pounds per person
per day in 1999? During this 40 year period, educational and advertising
programs were spawned to get people to create less waste and to
recycle. While recycling rates did increase, the per capita waste
almost doubled. Why do you think that this occurred?
- Voluntary recycling programs have been met with mixed success.
What actions do you think could be taken to increase the participation
in recycling? How would these actions be an improvement over most
current programs?
Now
that you have read about landfills and solid waste, it is time
to experience it firsthand by taking a trip to the closest landfill.
If you do not know where this is, you can check with your local
city or county government offices to find it. While at the landfill,
consider the following questions.
- How
would you describe the smell in the air near the landfill?
- What
method is being used at the landfill to ensure that trash is not
flying away in the breeze everyday?
- Do
you see any attempts to use modern methods of protection at the
landfill, i.e. leachate recovery pipes, methane recovery system,
landfill liner, etc.?
