Food scraps composting capacity in and near the Bay Area is very limited. It is also expensive and difficult to permit new facilities that compost food, whether mixed with yard trimmings or not. Combining food scraps with yard trimmings in Sunnyvale would generate 20,000 tons of material and there are no facilities available to take that quantity. Keeping the food scraps separate from yard trimmings enables more options for reuse, whether processed into animal feed or used in anaerobic digestion for energy. If we used a separate container for food scraps, the extra trucks and carts needed would increase collection costs and cause additional wear and tear on the streets from collection truck traffic. Residents would also have to store four carts instead of three.
