Subject: Used fixer?
I would like to start developing my own black and whites here soon.
But I wonder what to do with the used fixer? So I thought I'd email
and see what y'all do?
What you have to do with it depends on where you live.
The silver in fixer is pretty inert, and the amount of it that a home
hobbiest would be pouring down the drain is small enough that there isn't a
concern for environmental contamination, but you local codes may presume
that a home darkroom and a giant wholesale photo lab are the same thing.
It isn't financially viable for the home darkroom enthusiast to do silver
recovery, but you can, I am sure, buy a recovery cartridge from a lab
supplier and extract the silver from your spent fixer.
I'm guessing that one cartridge should last a home darkroom several decades.
When I was running my darkroom as a business I took my spent fixer to my
local camera store and let them run it through their recovery sytem. I
didn't make any money off of it, but I was pumping out enough spent fixer
(several liters a week) that it was the right thing to do.
As a hobbiest, I'd just be pouring it down the drain.
