ELI5 Why can’t we just burn all our trash?

I know pollution is most likely the answer, but I’m curious on how bad it actually is and why we need to dispose of it properly.

There are actually some power plants that burn trash, given some local/ state government subsidies they can be profitable but oddly enough produce less harmful emissions than coal fired power plants. Slightly worse than natural gas though.

But to answer your question, it’s currently not cost efficient to do this in a controlled setting without government subsidies.
