ABSTRACT:
A continuous composter is provided with self contained aeration zones so that air circulation is confined to any one zone to avoid transmission of bacteria through a composting tunnel. An inlet fan and an exhaust fan are provided for each zone and suction through the exhaust fan is provide stronger than inlet pressure so that gases do not percolate through the tunnel. Similarly water and leachate are removed from the system without contact with downstream composting garbage. Any recirculation of gas or leachate takes place only in the zone from which it has come.
