Can anyone suggest another way of disposing or re-using the silver metal from this experiment, a 0.5m Silver nitrate was used with copper wire, I know the copper solution can be disposed of by the sink, but can the silver metals be placed in the normal waste? I know it can be recycled with concentrated nitric acid but this will be time consuming.

Many thanks.

I keep any silver waste in its own bottle. It can then be collected by your hazardous waste disposal contractor with all the other waste that cannot be washed down the sink.
Alternatively, photographers in the olden days recycled their silver compounds by going through a reaction with thiosulfate and zinc powder. As always with these things, google is your friend.
