Extra Information:
How much food goes to waste because students are too busy/stressed to eat/cook/use it before it goes out of date? ... I don't know, but probably a lot.
My suggestion is to have zones placed around campus where students can put the food that they know they won't be eating/cooking, that can then be taken for free by other students who have the time to cook it. The zones could also contain a fridge for milk, yoghurt, etc. The zones could be clear of out of date things at the end of each day.
Less food waste + free student food = no brainer.
