Abstract

A digester (10, 49) for composting biodegradable material has a plurality of treatment compartments (16-19, 21a) one above the other with respective closable openings (26-29) in the floors thereof to allow material to pass through the digester compartments in a controlled manner. The uppermost compartment (16) has inlet means (20) for receiving a batch of material to be treated and means (36-40) are provided for transferring heat into the compartment (17) immediately below the uppermost compartment so as to heat the floor thereof and thus enhance digestion of material therein, the heat being transferred from one of the lower, hotter compartments (18, 19). Means (46) are also provided for spraying water in the chambers, the water being heated by means of heat from one of the compartments, and there are also means (50) for blowing air into the compartments. A transfer means, such as an elevating screw (50), can be provided to move material from a lower compartment into the uppermost compartment (16).
