When we moved to a house in an area with municipal composting, we were amazed by how much our trash volume was reduced by diverting compostable materials to the compost stream. Some of that is food waste, but a lot of it is things you'd never consume -- vegetable peels, eggshells, old coffee grounds, even food-soiled unwaxed corrugated cardboard (i.e. pizza boxes). On any given week, it's half or more by volume, and well over half by weight.
