ELi5: Why can’t you boil a sponge to sanitize it?

Googling repeatedly tells you to just buy a new kitchen sponge, never boil them because it doesn’t work. But why wouldn’t it clean them?

LPT: Buy biodegradable sponges, and cut them in half. The smaller sponge is easier to handle and it makes the whole sponge last longer!

Does anyone have the specifics about our use and discarding of sponges? Somewhere I read we are creating significant environmental damage by throwing so many sponges away.
