(JP8506792-W)      Continuous composting appts. has an enclosed tunnel with inlet and outlet ends. A conveyor track runs through the tunnel and a series of conveyor trays may be shunted through the appts. The trays contain material to be composted which is agitated and aerated during its progress through the tunnel. The trays are shunted by means of a ram, the stroke of which is set to a chosen shunting increment for the conveyor trays.    The trays (24) are shunted through the tunnel on the conveyor tracks. Material for composting is added from the conveyor (15) through sliding door (17) to a suitable depth in tray (24a). The tray is then stepped forwards by means of a ram (26) which has a stroke sufficient to allow for the next tray (24b). Ram (26) is then withdrawn and tray (24b) is inserted between the ram and tray (24a). The number of trays and the length of the tunnel are such that composting is complete when a tray (24) reaches end (18) of the tunnel.    USE/ADVANTAGE -   For the continuous composting of waste material. The invention provides an improved composting appts. which allows proper aeration during the composting process, avoids compaction of the composting material and inhibits the unpleasant smells normally associated with composting.
