Thinking of it... Recycling of these computers will be challenging - how do you dispose an item made from "unobtanium" ?

Crush it into sand? It is one of the hardest materials, one needs a harder material to crush something. Heat/cool to have it crumble does not work well either with ceramics.

Melting it into glass or something? Might not be practical due to extremely high temps required.

Using it as "pebble" in road/bridge construction? Not sure if concrete will be able to stick to it.
