ELI5: Why is it that pretty much no matter what goes into it, garbage always ends up smelling the same "garbage" smell?

Is there a specific reason for this? Sometimes I'll have a lot of potato peels or cardboard from TV dinners, sometimes just an empty milk carton and some banana peels, but no matter what, once that bin is almost full, it always has that same pungent garbage smell. Why doesn't garbage smell specifically like the things that make it up instead of just one specific garbage smell?

When you smell garbage you're not smelling banana peels or potato, you're smelling the rotting remains of those things.

In general the products (gasses, etc) of rotting are the same, no matter what leads to it.

Garbage made up of *clean* plastic, glass and dry paper is likely not to smell at all.
