What to do with unknown copper waste?
So, from the experiment I did a while ago, I still have some copper waste left. I had thought that it was all copper hydroxide and basic copper
carbonate. So, I added acetic acid to covert it all to copper acetate so that I finally had generally the same product.
Well, that didn't end up working. A lot of it converted to copper acetate, but a lot of it stayed as an insoluble solid, even after adding distilled
water. Thus, I am now stuck with some copper acetate and unknown blue waste.
What do I do with this?
And, for the future, what do I do with unknown waste in general?

You could probably just put it in a container and save it or just take it to a chemical waste disposal since you know that it contains copper. As for
other waste, I just try to save all the stuff I can't pour down the drain if it's inorganic, and for organics I just try to evaporate or burn them
off.

Do electrolysis with lead dioxide anode to plate out the copper out of your acetate.
The blue stuff could be any of the following :
Copper Oxychloride
Copper Carbonate
Copper(I) Chloride
ALL ARE INSOLUBLE
Tho the carbonate should have reacted with the acetic acid. Try adding more.

Couldn't you just add sodium hydroxide or carbonate to precipitate out the copper as the hydroxide/oxide/carbonate?
