Cool idea, but probably not that useful outside the US, where most people don't waste food like Americans do, at least, that's what's portrayed on tv and movies from America. We're always appalled at the giant spreads of rood which are summarily tossed into the garbage disposal or bins in American entertainment media. We teach our kids to take what they're actually going to eat, we don't produce 10 servings for 4 people, etc. There is no actual food in my garbage that goes out every week. When there are small scraps, that's doggy treats.
