Abstract
Waste compaction apparatus has a screw conveyor which conveys material along a passage toward an exit nozzle which constricts the flow, to cause compaction. The screw conveyor is slidably mounted on a shaft, biased toward the nozzle. This allows the screw conveyor to move axially during compaction to help remove or avoid blockages within the apparatus.
