All of the packaging needed for a lot of food at home as well, I feel like restaurants probably throw away less packaging comparatively with how much they get in bulk.
All of the plastic bottles for sauces, plastic containers for spices, meat and certain produce items that come packaged in plastic and styrofoam, plastic bags for bread and rice and pasta and junk food. Frozen items packaged in plastic in boxes that took energy to keep frozen before we spend energy to heat them within a minute or two, just because we’re too lazy to cook today.
Not to say that restaurants waste no packaging, but they’d use less given the volume of supplies they source, and likely prepare more in-house rather than buying pre-prepared.
I’d say restaurants are probably way more efficient in terms of waste and energy consumption than the average household. Cooking in bulk for a lot of people is better than a lot of people individually cooking for themselves.
Usonian evokes that weird Frank Lloyd Wright concept of kitschy suburbia that the US could do with substantially less of.
