Well, I don't know about the UK, but here in the US there are people who want to divert binned/trashed food to people who could really use the food, or to organizations/agencies that would distribute the food to the hungry. Perhaps all that is needed in the UK is for someone to step up, take charge, and say, "All that food being binned is wasteful and I'd like to get it to people who could use it." There's an opening. Anyone in the UK want to take it?
ETA: I also want to add that I do think it's shocking that so much food in the UK gets binned, as I know how many people in the UK and elsewhere in Europe starved during and after WWII.
How did you guys go from "I"ll eat dirt just to stay alive" to "I bought this yesterday, now it looks a little dodgy, so it's going in the bin"?
