(JP9508345-W)      Organic material, partic. domestic waste, is composted by disintegrating and feeding into the inner lower part of a container so that material is moved upwardly in zones as successive amounts are introduced and compost is withdrawn from the upper end. Air is pref. introduced into the container lower end and the material is forced through a bottom centre inlet in the container by a plunger in a feed tube in which there is a transverse disintegrator knife. The plunger pref. has longitudinal grooves corresponding to the sawtooth-shaped cutting edge of the knife.    ADVANTAGE -   The method provides rapid composting and it is easier to withdraw compost.
