Per household or purchasing body (as in a store or restaurant) I have my doubts. Never in my life have I dumped 3 dozen perfectly edible sandwiches in the trash on any given day.
There are a lot more households than there are stores or restaurants so in aggregate total homes may make for a greater sum, but that’s the same kind of logic they use to say people need to all switch to paper straws and forgo the AC in summer while the rich fly about in personal jets and rockets for a joyride.
For those willing to do a bit of CLI work there are even tools to pull your whole library automagically. Just make sure you got the space for it. Sitting at just over 1.5 TB here.
