Thanks for the link, but how you dispose of all the etching solutions, acid, etc?

I do not know about any hazardous material disposal factory in my country, and it would be too overkill to call the Fire Department's HazMat response team. These guys are meant to respond in serous things like terrorist attacks.

So, how can these things made safe? I really do not want to flush them down the toilet...

Do not throw the etching solution away, you can use it many times. I have used it for many years and keep it in a plastic container, air thight.

In Most Countries, It is Illegal to Flush this down the Toilet or Sink.
