Re: [GreenYes] Plastic-Coated Cartons
Regarding the comment about dioxin being destroyed by incineration;

There are industry scientists that profess that if dioxin is incinerated at
high enough temperatures that it will be destroyed. The paper most cited on
this subject is by Rigo, et al.

The following comment on Rigo et al is by Dr. Paul Connett of Cornell

"The Columbus incinerator operator's own logs indicate quite clearly that
the waste was specially prepared for this test burn and thus not typical of
the way waste is handled on a day-to-day basis.  ...Dr. Rigo declined to
elaborate on any of his calculations or substantiate Mr. Diamant's claim
that our conclusions were based upon "selective, inaccurate, incomplete and
defective data." Meanwhile, as reported in the following issue of Waste Not,
the Columbus authorities have decided to close down their ill-fated trash
incinerator, after just 11 years of costly operation, instead of paying for
an expensive retrofit. We believe this sends a clear message to many other
communities in the U.S. saddled with incinerator dinosaurs: "it's cheaper to
shut them down."

How reliable the Rigo paper is, again, depends upon ones particular
definition of science. But considering that the data are not made public,
the work is highly suspect and therefore not reliable.
