I live in the countryside with a septic tank and well water. Usually (as in my case) homes with septic cannot have garbage disposals. We’ve lived just fine without one for 7 years now..
And before that, decades ago, I lived in Japan where garbage disposals are unheard of.
In Japan we put small bags of garbage out frequently in the communal garbage pickup place. Most people keep a little mini-garbage can in the corner of their sink that gets bit of scraps & leftovers in it—and throw it out once a day (or more often if needed).
Here in the countryside..I do have an under-the-sink mini garbage spot..but if it’s anything stinky or unpleasant it goes to the outside garbage can. If it’s REALLY bad or rotten smelling (and in one of my disposable-type containers) I might just throw it away IN the plastic container still.
My hubby loves to dispose of some things (our Halloween pumpkins and Watermelon rinds, especially) by tossing them in the woods around our house because it feeds the wild animals (deer, coyote, black bears) and makes a pleasing loud “THUNK” noise when he chucks it off the back deck. ;)
