<p>A continuous composter comprises a train of composting in an elongate enclosed tunnel. The trays run on tracks above the level of the base of the tunnel. Garbage enters at one end of the tunnel and compost is removed from the other end. A ram shunts the trays stepwise through the tunnel. The tracks may be U-channels the webs of which are connected to tunnel side walls. The trays rest on one of the U and the other leg of the U extends over the edge of the tray to protect it from being fouled by garbage. Computer control may adjust proportions of aerating gas with recycled gas.</p> |
