    I have a waste hauler to take it away. But sometimes I pour it down the drain, but not on a regular basis.

    I remember doing a project in chemistry class years ago about disposing of exhausted fixer. If you mix in some table salt (alot of table salt) and let it settle, the salt causes an ion exchange and the silver falls out of the solution as a white sludge that can be filtered out after the other liquid is decanted off. It's the silver that tends to be the worst part of solution after it's disposed of.

    Crumpled aluminum foil insead of steel wool. Just as effective, cleaner, and gives me some useable silver sludge for jewelry and other "fooling around" metal working projects. I't easy to tell when the silver is totally removed when a few bits of aluminum remain in the preciptate. Dump the fixer (siphon it off) after stripping out the silver.

    Stripping silver with aluminum also makes it possible to re-use the fixer. This was discussed by Chapman in Darkroom techniques about 10~15 years ago.

    Why is it bad to dump silver? I would have assumed that it was the thiosulfates that was the environmentally hazardous part; what harm does the silver cause?
    f/22 and be there.

    Pour it down the drain with not an ounce of guilt. Every household in the country uses more dangerous and harmful chemicals for cleaning.
