To DAVID BELL (couldn't send to whole list via your post so used David Ross)
I apologize for misquoting you. I was responding to some comments you made
and some Michael made and lumped them. I won't do it again.
Have you had any experience working on environmental issues with
politicians? If "no politician can ignore the logic" then we wouldn't
still be discussing dioxin and incineration. The problem would have been
fixed years ago. The problem is that some politicians can and do ignore
logic, in fact all politicians ignore logic at times because of limited
resources and confliciting demands. I'm not saying that when they hear
something logical that they do not recognize the logic (although some do
not) but I am saying that they have their own agendas and those agendas are
not always tied to the health of their constituients.
Run a CFCs time line versus a dioxin/incineration time line. My memory is
not perfect on this issue but I think the dioxin/incineration relationship
came to be know first. Why is it so far from being fixed? The political
environment was much more favorable to environmental advocates in the first
half of the 1990s than it is today. Also advocates had several interested
parties on their side. They had scientists, and replacement chemical
manufacturers, and equipment suppliers. Most cooling/refrigeration
equipment didn't have to be replaced all at once like it would with
incineration. With CFCs lots of equipment just needed one chemical to be
swapped out for another. Also refrigeration/cooling/ac equipment tends to
last a shorter time than incinerators. Also net,net the CFC changeout just
caused increased sales and new opportunities for vendors, they did not lose
any market segments, like I'm sure incinerator manufacturers would (small
models would likely be to expensive if they were compliant). Plus you have
the whole issue of chlorinated wastes that are not burned in incinerators.
This certainly is not something chlorine manufacturers of the CCC would be
too happy with, especially if you remove chlorinated derivatives that likely
get burned and the chlorine industry does not get to participate in the
replacements. My understanding is clean incineration will cost much, much
more than a CFC changeout. Also if you remember there were a core of
scientists that swore the whole CFC hole was a fabrication. It was just
because industry and environmentalists pulled together that the job got
done.
I didn't get into the sedcore file as it would take download time and it
seemed from your statement that again they didn't tell you why the dioxin
was there to begin with. I do not know what industry was on these lakes or
where they were, but I'd bet that they had bleached paper mills on them.
Mills have been improving over the years as we all know and especially in
the 1990s dioxin was reduced as mills moved away from chlorine bleaching.
This however doesn't really address that we need to decrease dioxin
formation in incineration.
