Abstract
Apparatus and method for separation, recovery, and recycling municipal solid waste and the like by introducing solid waste materials into a rotatable pressure vessel, rotating, pressurizing, and heating the pressure vessel and thus the waste material 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 which forces the processed solid waste material through a constricted area adjacent the exit of the pressure vessel.
Claims21
A method for separation of recyclable material from solid waste materials comprising:
- introducing a predetermined quantity of waste materials into a pressure vessel including a pressure chamber;
- heating said waste materials to a predetermined pressure and temperature for a processing period lasting a predetermined period of time by introducing steam into said pressure chamber;
- applying an extruding action to said waste materials during said processing period;
- recovering said mixed waste from said pressurization chamber for classification;
- and
- separating and recovering the recyclable materials from the classified material.
Apparatus for separation and recovery of recyclable materials from solid waste materials comprising:
- a rotatable pressure vessel having a chamber including inlet and outlet means;
- means for introducing said solid waste materials into said inlet means;
- means for pressurization and heating said solid waste materials in said chamber;
- extruder means carried in said vessel for applying an extruding action to said solid waste materials while said vessel is in a heated and pressurized state, said extruder means being further disposed for expelling the processed solid waste from said vessel responsive to exposing said solid waste materials to heat and pressurization for a predetermined time period.
Apparatus as set forth in 11 wherein said waste materials are municipal solid waste materials which are obtainable from landfill mining.
