Chips have many metals in them and sometimes extremely rare metals. Silver, gold, indium, titanium, tungsten, etc all are used to some degree. Among many others, (those are just metals that I personally have experience in, in semiconductors)
This is pretty great. Staff sometimes ask me at work if we recycle old electronics, to which I can truthfully say yes. I don’t mention that the recycling process begins by soaking it all in acid…
Some of the chemicals that go into making circuit boards are pretty nasty too. When I was learning about them, arsenic was a component of semiconductors. I don’t know much about the chemistry, but I think having that in your air or leaching into your groundwater would be bad news.
