Yes, it's very easy to make H2O2 decompose. Activated carbon does it
very quickly, but charcoal works too. Just don't use charcoal
briquettes imbued with lighter fluid!. And if your sink is getting
damaged, I would guess that the problem is too much base, not too much
H2O2. Strong bases can etc

Used etchant is *always* hazardous waste, because it contains copper,
which is toxic.

The whole point of HCl/H2O2 solution is that you *dont* have to
discard it. Over time, it grows into a CuCl etchant which is air
regenerated and shelf stable.
Otherwise, mix NaOH slowly until the solution turns from clear green
to opaque white. Let the water evaporate, bring the remaining coppe
Do you mean muriatic acid and hydrogen peroxide? Those are not
hazardous chemicals, if they are neutralized. The hydrogen peroxide
is easy to neutralize; just put a piece of charcoal in the bottle and
it should decompose. Exposing it to sunlight will also work.
Muriatic acid could be harder, dep
