[GreenYes] Re: INCINERATOR INQUIRY



Just a very quick reply:

I know waste disposal can be a specially tough issue for island
communities, but an incinerator is a very poor idea, will all sorts
of possibilities for creating health and environmental problems. Air
pollution, water pollution, ash disposal, real cost, health of
workers and the general public....all are hard--sometimes
impossible--to manage and it is not to be expected that Anguilla
would have the technical and regulatory infrastructure to deal with
these issues on a continuing basis. Incinerators can be marketed as
the clever, simple, almost magical solution to waste problems, but it
never turns out that way.

To respond to just two points you raise: Heavy metals are elements
and cannot be destroyed at any temperature short of the
nuclear. Medical wastes tend to be loaded with chlorinated plastics
that produce dioxin-family compounds when burned. These compounds
may not be present during high-temperature combustion but may form in
the off-gasses downstream.

Sometimes the real marketing point on air pollution is some version
of "put it on the lee side of the island and all the fumes will blow away...."

More people can be usefully employed in "zero waste" programs than in
feeding burners.....

Alan Muller
