I feel that there are additional issues to address in the outline:
1) Food processing: besides reducing packaging, retailers should seek for better ways to keep food fresher for longer periods without using more chemicals. One of the reasons why consumers waste food is that it goes off before they can eat it. When food are obtained directly from the farms it last longer!
2) Food distribution/retailing: Supermarkets and shops should stop advertising big savings for big buys.
3) Food redistribution: Some places have implemented an application for mobile phones so that restaurants offer reduced prices for food that is about to expire.
4) Food recycling: green bins for organic wastes should be allocated in schools, Universities, working places... Not only consumers eat at the bars and cantees in their working places but also bring food to work and the waste ends in the "general waste" bin.
