About
the Author. Paul Connett is Professor of Chemistry at St. Lawrence
University, Canton, NY, where he has been teaching since 1983.
Since 1985 he has been engaged in research on waste management,
with a particular academic interest in the generation of dioxins
by incinerators and their build up in the food chains. He has
shared knowledge on waste management with communities in several
ways. He has given over 1500 presentations in 48 states in the
US and 40 other countries. With his wife Ellen he has co-edited
the newsletter Waste Not, which is published 48 times a year and
is now in its twelfth year of publication. With Roger Bailey,
a colleague from the Fine Arts department at St. Lawrence University,
he has produced 40 videotapes on various aspects of waste management,
including a series of ten on dioxin. Over 6000 copies of these
videotapes have been distributed. With Tom Webster, a researcher
in the Department of Public Health at Boston University, he has
co-authored 7 published papers on dioxin. Paul Connett has played
a crucial role in the grassroots movement which has seen over
300 trash incinerators proposals defeated in the US, with virtually
no new proposals in the offing. Ralph Nader said Paul Connett,
"He is the only person I know who can make trash interesting."

INTRODUCTION
Frequently,
after giving a blistering attack on the idea of burning trash,
I am asked, "Well, if we can't burn it, what can we do with it?"
Such a question becomes more emphatic when it is coupled with
a statement about how scarce available landfill space is in the
area. Often, the questioner is after an alternative "technology,"
because they have become accustomed to the salesmen that offer
them "turnkey" solutions. Give us this much money and we will
solve the problem for you, is what they are used to hearing. At
the outset, I have to stress that there are no "magic machines"
which can solve the trash problem.

THE REAL SOLUTION BEGINS WITH SOURCE SEPARATION
Trash
is a not high tech problem. Technology has a role to play but
only when judiciously applied to carefully selected components
of the waste stream. The real solution has more to do with organization
than it does with machines. Solving the trash problem takes a
lot of hard work from municipal officials plus a little daily
effort from our citizens. From the citizens' perspective, trash
is made by the ten things at the end of our hands, and if we want
a solution that we and the planet can live with, it is those ten
things that have to be co-opted from the very beginning. In essence,
the solution begins with source separation. Trash is made by mixing.
Trash is avoided by separating. Avoiding expensive and potentially
dangerous incinerators and huge regional landfills requires keeping
our discarded items in several well defined categories:
1)
avoidables
2)
reusables
3)
compostables
4)
recyclables
5)
toxic materials, and
6)
materials which are currently non-recyclable or compostable.

FIVE KEY PRINCIPLES
Before
I get into the nuts and bolts of the alternatives, in my view
there are five key principles that need to be satisfied to make
the source separation approach successful. There are to make sure
that the program:
A)
Be kept simple. Do not bring on complicated machinery until you
have exhausted the low tech alternative.
B)
Be kept local. Do not export or import trash. Exportation of trash
means the exploitation of distant communities who are usually
too poor or too politically weak to resist the process.
C)
Be integrated with the local community. In each community there
is usually a large number of people who are eager to help solve
this problem. Their services and goodwill need to be harnessed
effectively. Moreover, many of the solutions to waste can be integrated
well with other community gardens and other community building
activities. In my view, which makes the waste stream unnecessarily
large.
D)
Be integrated with the local economy. Handled well, source separation
strategies and affiliated activities can generate many local jobs
and local business opportunities. A key question for decision
makers is: "How can I make sure that every dollar we spend on
trash beyond what we spent on the local landfill is made to work
twice. Once to solve the trash problem, and twice to generate
local economic activity?" It is here, especially in developing
countries, where the latter leaves the community and probably
the country. Money spent on reuse, repair composting, recycling
stays in the community. A study in North Carolina has documented
the enormous impact recycling has had in their economy. (1)
E)
Move in a sustainable direction. We are not going to reach sustainable
societies overnight. However, it is important to move in the right
direction. A policy which moves to minimize the amount of material
that is burned or buried in the right direction. From a planetary
perspective, sustainable development requires the throughput of
matter and energy through our economy, while looking for other
ways of generating satisfying lives. This principle relates strongly
tot he stimulation of community development as discussed in the
principle C) above.

COLLECTION SYSTEMS
Figure
1 is a schematic illustration of a three container collection
system. There are many variations on such scenarios. A key point
to remember when a community is embarking on a source separation
system is to organize the separation around the existing collection
system. If the community is used to curbside collection of trash
then it is best to organize the collection of recyclables and
compostables at curbside. If, on the other hand, the community
is used to taking the trash to the landfill (this is often the
case in small rural communities) or a transfer station (sometimes
the case in suburbia), then it is best to organize the collection
at these facilities.
