Chicagoland Processing, Mt. Prospect, Illinois, is another source of
information about reclaiming silver from black and whitefilm. They are
involved in reclaiming the silver and then selling the film base back to
firms for polyester recycling. While they recover silver on a very large
scale, they may be willing to talk with you what you need to know about the
process. I think you'll quickly see that relcaiming silver from film is not
something that can be done well on a small scale.
