[sdiy] Disposing of cupric chloride

[Karl Ekdahl]

I'd prefer to do the disposal in an as environmentally friendly way as possible, hence why i was hoping to be able to "clean" the liquid part with the aluminium. However, i've realized that maybe i just have to wait a bit longer, it's only been brewing for about a day so far.

If the water is blue then there is still copper in it. I would pour the 
whole bucket in a closed container, clearly label it, and bring it to 
your local waste disposal.

Good luck,

Jack
