Re: silver removal, it is my understanding that one can use a ball of steel wool to replace the silver in the solution if you do not care about recovering the silver easily. If you throw steel wool in a bucket of spent fixer the iron from the steel wool will swap the silver in solution...the result will be an iron-rich fixer solution (relatively harmless) and a silver sludge. Filter the sludge and the rest can probably go down the drain without consequence, although admittedly I've never done this on a septic system.
I have a generally poor understanding of the finer points of chemistry, so perhaps someone wants to clarify that...but as far as I know that is the simplest silver recovery process. Not sure if it works in reversal bleach as I've always considered that too harmful to dump, silver or no silver.
