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?

The secret I’ve found to long lasting good smelling sponges is to always rinse them out after use, wring them out, and store them so they can completely dry out (I have a basket that suction cups to my sink). None of this boiling or dish washing needed.

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.
