Electronics in general should be banned from landfills and sent to recyclers. Many will pay you for
circuit boards. This only makes sense though if you have a large quantity of boards. We tear down
discarded equipment and do our own material separation and pass the accumulated mass off to recyclers once
a year or so.

What concerns me about the Pb free solder is what do we replace it with? While we have a good historical
base of Pb and its effects, what do we know about the long term effects of Indium as a replacement.
Sometimes the devil you know is better than the one you don't know.
