I agree that it does save some money but if one uses CuCl, like I do,
the cost difference isn't nearly as large since I can regenerate my
etchant via bubbling or kick-start it with about 50 mL of H2O2. And
I only have to have one set of chemicals, one etching tank, and so
on. Still, I think its a pretty cool idea and definitely worth
considering if one is using consumable etchants (like FeCl or AP).
It is definitely worth it if it significantly reduces the disposal
problem.
It would be good to answer questions here - they are likely to be of
interest to many of our members.
