I work with e-waste, we crush, grind and filter the gold and copper out or the rest of the junk.
I think that could be i good way to recycle electronic circuit in the same way that ore is turned to dust then clumps electronic circuit could be turns into electronic circuit bust then filtered into copper and iron clumps, a better way of recycling but you can't recycle blue to red then red to green, it's all just one big mic of copper and iron sludge.

Hi big guy.
Cool to see players with irl competences come here to suggest me stuff!

And I must say that enhanced efficiency on Fulgora (the first scenario that your post makes me think of) recycling or something dedicated on circuits could really be interesting to explore as a field.
I'll definitively keep that in mind, thank you!
