Abstract
Abstract A material compacting and disposal apparatus comprising a press unit for compressing the material, an extrusion housing for further reducing the volume of the compressed material and a disposal conduit for disposing of the material. The press unit comprises a precompression chamber having a gate pivotally movable therethrough and a compression chamber oriented below and communicating with the precompression chamber and having a press platen movable longitudinally therethrough. The gate pivots through the precompression chamber, compresses material delivered thereto into the compression chamber and forms the top of the compression chamber. The press platen then moves through the compression chamber and forces the material therein through the extrusion housing and into the disposal conduit. The apparatus may be mounted on the floor of a building or attached to a refuse truck wherein the disposal conduit enters the storage compartment of the truck. In the embodiment used in buildings the disposal conduit communicates with a storage housing which has a reciprocating conveyor therein.
