Eli5: why we don’t combine compost and regular garbage in landfills

277 views

Where I live we have two separate waste pickups, one for compost, any organic waste from yards like grass clippings, leaves, etc. And one for regular trash. Wouldn’t it make sense to combine them? All that organic waste mixed in with the trash would have to help it decompose, right?

In order to decompose properly, compostable materials need a lot of oxygen (aerobic decomposition). Landfill is about shoving as much as possible into the smallest volume – leaving no room for oxygen so it decomposes anaerobically.

These two processes are totally different and give different things at the end.
