David Kidman has experimented with onion fixer. He says to liquidize
the onions and use 1 kg for 1 liter and have patience. You can see
his onion film here: http://www.davidkidman.com/films/DogsDinner.html
Many still photographers have experimented with non-toxic chemistry:

There are also a few websites in French that give recipes for
ecological chemistry:

Poke around and you'll find a lot of people interested in this.

Hello all,
I've been experimenting with various alternative formulas for black
and white developing that involve non-toxic household chemistry but
I am curious if anyone has done so for color film?
Also, why and how do onions work as a fixer? How do you prepare
them to do so? I know an extreme salt solution (extreme as in you
put in so much salt the water can't take it anymore) will work too
but it takes a long time (2 days I heard). How long do onions take?
Isn't the real danger from fixer the metallic silver that needs to
be properly disposed of?
Finally, has anyone come up with a good substitute for r-9 or r-10
bleach in the bw reversal process.
Thanks
Kathryn
