Re: what's happening to Kodachrome.

>>The residual is cyanide.  It was declared highly hazardous and Kodak was
limited to two or three labs in the continental US in order to continue
manufacture and development of this film, mostly due to the very particular
resolving particularities and to the economic and political nature of the
patent, I'm sure.


There is a big Copper mining concern in Utah that uses Cyanide literally by
the open boxcar load. Hundreds of tons of the stuff yearly. Certainly, if
they can clean the effluent well enough, Kodak can do the same with the
tiny fraction of the amount they might produce. I would be interested in
learning where this story was reported.

Incidentally, most any chrome plater uses cyanide in the plating baths.
There are no laws saying that there can be only this or that number of such
companies.

I would be interested in any additional information you can point me to.
