Here where I am in NC, we have a silver recovery unit at our mini-lab. When we drain the waste at closing, it's run through that unit to remove the silver before it's flushed. If we didn't have the silver recovery, we'd have to collect our waste solutions for disposal as haz-mat. I've taken my exhausted B&W fix and added it to the C-41 process waste and run it through the silver recovery. So, I guess the best thing is to talk to a local lab (mini or otherwise) and see if they'll take the used fix for proper disposal according to whatever the local law is. The company that supplies our silver recovery unit sells the recovered silver, so it's recycled for industrial use. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
