If you look at post #56 of that thread you'll see that I hinted at inceneration of those filters (at least the charcoal ones). I don't see another solution. But then again one needs a (municipal?) service that takes care of such, but at least that stuff is off the sewage system. And with incineration I had in mind hazardous waste inceneration. This takes place at higher temperature (better cracking up of molecules) and better filtration.
So that term "disposal" as indicated in the title of this thread may be ambiguous.
Concerning that silver, you are right claiming the money for that silver out of your fixer. My remark was directed at the effeciancy of home de-silvering compared to a commercial business under the aspect of being most ecological.
