While we're on the subject--for those who use the method of pouring spent fixer into a jug or a vat with steel wool--do any of you folks actually have someplace that will buy the sludge and recycle the silver from it? If so, where do you send it? I realize that silver recovery companies have systems with cartridges and such for larger labs, but does anyone have a name of a company that takes silver waste in the form you would get from homebrew silver recovery? I realize that it might take a while to amass enough sludge in a home darkroom to make it worth recycling, but say I wanted to save it up and do it every couple of years. Where would I go?

No Google answers, please. I want to know who really does it and what their experience has been with companies that will actually take this stuff in small quantities.
