Garbage chutes are a luxury I've only recently acquired, but it was done well in my opinion at my building. The room is tiny but enclosed with a garbage chute with a closing chute door that has a rubber gasket to seal it. Negatively pressurized so any remaining smells aren't pushed into the hallway. Everything goes down to a compactor in a ventilated utility room. How it's processed from there, I'm not sure but smell certainly isn't an issue.
