Meanwhile, in every city everywhere, we bury mountains and mountains full of arbitrary garbage. This stuff is not buried and a lot ended up burning. At least it's sorted! And arguably burning it could be better than burying it.
If you bury it it's (relatively) inert and all stored neatly in one place. Whereas if you burn it you release it in the atmosphere, release carbon and probably not-so-great residues everywhere.

A clothes wildfire is very much absolutely not that.
