Yep, we definitely don't have any kind of law prohibiting a business from disposing of food waste en masse.

We do have a ton of liability laws that would punish them from distributing leftover food though, should someone get sick after it is distributed.

Also don't have any kind of thing preventing households from wasting food either. I suspect countless of perfectly fine meals are disposed of every single day, probably enough to feed the country twice over, if not more.

It's a tough problem in a land of excess without near-total elimination of privacy and agency.
