I have been putting old Brillo pads in recycling for years
Then I read you shouldn’t……. Also some plastics and paper gets diverted to landfills or burning , it’s getting to the point it’s easier to just throw everything away.

I doubt their material is very salvageable. It is very fine steel wire so I would be surprised if very much of the metal is recovered at all.
If buried landfill they will rust harmlessly away, back to iron-oxide (as was the original iron ore), although of course adding to the attrition of the metal as a re-useable resource.
Not all plastics are recoverable. The thermoplastics are, to a point, but not the thermosetting ones, though it may be possible to grind some of them to a fairly inert granules as a filler for other composite materials.

@wildbill83 You need aluminium powder too, though, for "Thermite".....
I first heard of it as the fuel for a flame-cutter designed for melting through concrete.
I do know if you pass an electric current through steel-wool it does light up!

@ArishMell works better the finer the iron oxide & aluminum powder, easier to ignite with a bit of magnesium ribbon (can be used like a fuse/give a delay), still need a torch to ignite.
a fist sized amount will burn right through a good sized chunk of iron like an engine block

@wildbill83 Ah - you have professional experience with the process? I know it's also used constructively, as in forming continuously-welded railway lines.
