Use for Exhausted Developer?

Is there a use for exhausted paper developer? ... that has turned golden colour from use and oxidation? Any kind of recovery or evaporative process to amuse a would-be amateur chemist? Purification by crystalization into components?

I've just been discarding film D-76 1:1 after each use, so I wonder about that too. I can collect them in empty plastic juice bottles.

I keep thinking in the back of my mind about various used household products, chemicals and photographic solutions that could be put into a sufficiently inventive solar device, perhaps with solar cell electrolysis, that would yield useful stuff for recycling.

I know in the case of used photo solutions there is not enough "market" for recycling, but my mind does turn in this direction.

Any ideas from chemists and others for fun or perhaps more serious use?

Let it evaporate somewhat and use it as drain cleaner, or test it as a soil sterilizer/weed killer. Most plants don't like highly alkaline soil.

I wondered if it might be sprayed on a lawn dilutely to act as a kind of lime against acid soil (tree litter), but there might be some poison potential. It could be sprayed late in the year just before the first snowstorm, but even so I don't think it is the best idea. Hence your smiley

Just pour it down a municipal drain, it will turn into salts and be fine.
Just think how much was pouring into drains in the 1920's-1960's and treatment processes were nowhere near today's.

I do see your are in Nova Scotia... don't know what your rules are up North. I'd like to visit though.

Cheers.
