ABSTRACT:
Apparatus and method for separation, recovery, and recycling municipal solid waste and the like by introducing solid waste materials into a pressure vessel having a rotatable section. The vessel is disposed for subjecting the waste material to heat and pressure while simultaneously applying an extruding action to the solid waste material. The extruding action is achieved by a rotatable extruder mechanism carried in the pressure vessel and rotated in response to the rotating section thereof. The rotation forces the processed solid waste material through a pair of constricted areas before the waste material is expelled from the pressure vessel by rotation of the extruder mechanism.
