the chemicals are liquid concentrate stock and mix easy !:9.
if you can't find them locally they can be purchased right off their website
their developer ( film ) is sort of like d76 and id11 but a bit different
and i believe it is metol free.
good luck !
I just dump my stop bath, but I collect the fixer and take it to the the "Household Hazardous Waste" collection center in Columbus. The silver in the fixer is not good for the environment. I've heard that it's not really an issue in the quantities that amateurs use, but I take mine in anyway. Fixer and selenium toner. I have known some folks to extract the silver from their used fixer. It can be sold, but I don't know who buys it.

the thing that makes the magnet easy is that it isn't just a sludge mixed with other stuff, but its silver that is electroplated onto
a cathode, so it is pretty pure ... if you look in the business listings / yellow pages near where you live under electroplaters
or refiners, you might find a place near you that would be interested in the extracted silver from your fixer ... you won't get rich
but after a while it might pay for a few boxes of paper or rolls of film or maybe gas for your car ...
good to hear you have a "waste-plan"
have a nice new year !
When I started to work on color paper at Kodak in 1971, we were just switching to the bleach-fix process that required Ag recovery be made using Fe cartridges, because the Fe became part of the bleach-fix. Many photofinishing labs were't happy about this means of Ag recovery because the recovered flake Ag from the electrolytic Ag recovery used with the previous process fixer was 'off the books' and 'was their retirement fund'. The Fe cartridge recovered Ag had to go through a refiner and thus was 'on the books' for tax purposes.

I wait until my fixer bucket gets about half full. 2 or 3 gallons, more or less. Each time I run the Silver Magnet, I get approx. 30 grams of silver.

At the current price of silver, that comes out to almost $1 per gram.
No, you won't get rich but it is certainly a worthwhile pursuit.
