My suspicion is that most of the waste is from the commercial sector and not from the residential. Even to the extent that it is just make food garbage separate from other garbage and then compost it directly. There's no reason to see discarded food as "wasted" other than for the fact our processes for managing the obvious consequence of home kitchens are either incomplete or totally missing.
