Ask HN: Why are electronics still so unrecyclable?

I was wondering why electronics and computer parts are so unrecyclable (is there a better word for that?).

From what I searched, only a small percentage of electronics are recycled and those that do, are through chemical processes. Electronics today use plastics and special metals, and extracting them isn't straightforward, because requires energy and big acid digestors.

Is there some kind of initiative on this area, on using other materials or designing chips and boards to be more recyclable or reusable?
