California School Districts Recycle Organics On A Large-Scale
Existing 32- or 45-gallon barrels were relabeled for “organics” in the cafeterias. Most schools switched to trays made from paper instead of polystyrene foam.

City of Bakersfield implements collection and composting system at its 53 schools to handle all types of food packaging in order to get at the “leftovers.”
