Abstract
A method and system for treating material, especially medical waste, municipal solid waste and paper, such as newsprint. The system includes an input component (12) having an air lock (20) and shredder (24); a pressurized treatment compo-nent which includes a feed screw (26) which feeds material into an extrusion tube that is connected to a rotating autoclave vessel, a pressurized outlet hopper. and an exit feed screw which feeds sterilized material into an outlet extrusion tube. In a preferred embod-iment, the autoclave vessel is sealed at its inlet and outlet ends in part by dynamic plugs of material which progress through inlet and outlet tubes, but at the same time form compacted, airtight barriers which seal the autoclave vessel.
