<p>Apparatus for the treatment of bio-degradable waste material (3) comprises housing (1) defining chamber (2) for receiving the material and means (10, 11, 13) for agitating material (3) in chamber (2) by supplying gas generated from bio-degradation of the material into a lower part of the chamber. Gas is withdrawn from chamber (2) and pump (8) compresses the gas, the rise in temperature produced by the compression being used to heat material in the lower part of the chamber by passing the compressed gas through piping (9) in the lower part of chamber (2), agitating means (10, 11, 13) recirculating the gas back to the lower part of the chamber. The agitating means comprises storage tank (10) for storing gas generated from the bio-degradation of the material and means for supplying gas (11, 13) from tank (10) to the lower part of the chamber, piping (9) being connected to storage tank (10). There may also be a lower set of agitation pipes.</p> |
