ABSTRACT:
A composting apparatus is disclosed which comprises a container (10) formed from a plurality of segments (12a,12band12c). An aerator (20, 521) is located in the container for receiving air from the exterior of the container and distributing the air into the composting mass within the container. The apparatus has a base (501) which includes a leachate chamber (454) for collecting liquid that strains from the composting mass during composting. An anti-compaction member (99, 527) is provided for preventing compost from compacting and blocking the aerator (20, 521), and a plug (570) provides addition or alternative air supply to the container (10).
