Hi Susan,
I've read two things about this, the first being that unless you're processing gallons a day, you're not significantly contributing to the chemicals going down the drain, so can just pour the waste in the sink with dilution.
I also however read that if you ask nicely at a local university, or photo lab, they might take spent chemicals off your hands, though I have not tried this so cannot say whether it is actually the case or not.
I will ask at my college course tomorrow night and see if anyone there has an opinion.
Chris

Check with your local government's waste management office. Some will take photo chemicals as part of their hazardous waste disposal programs. For example, here in Portland, Oregon, you can leave spent chems whereever they accept other household chemicals like old paint and pesticides for no charge. Just let them know what is in the bottles when you drop it off and they'll take care of it.

AS said above check the local waste disposal programs, but for fixer I normally let it exhaust beofre I dispose of it. Here I can pour it down the drain.

If you are on a municipal sewer system, then just toss it.
