Abstract
A biodegradable compost bin comprises a housing made of an organic membrane which may be folded into a relatively small, compact shape for ease of storage and shipment and easily popped open when ready to use. The housing has opposite open ends, one of which is adapted to be positioned on a supporting surface so that the housing forms an enclosure for receipt of the compostable waste materials through the upper open end.
