Certainly we all need to consider the "lifecycle" of all that we do. But
what is "a responsible recycling facility"?? In Saskatoon, about all that I
know of is silver recovery from the fixer. I am sure I am not atypical in
having a veritable storehouse of chemicals in my darkroom. In an ideal
world, each one would need a separate disposable program to make the
chemical acceptably benign to the environment. What are these other

Boy, I shall echo this statement. One must collect used chemicals and
take them to a responsible recycling site.
If one does dilute the effluent it doesn't make any difference for the
amount of "poison" placed into the ecological cycle is the same. The
dilution merely hides the fact of the material disposed.
