  • Treating method for converting wastes into resources and its equipment
    Patent number: 5756871
    Abstract: A continuous treating method for converting waste into resources is provided that includes the steps of comminuting, liquefying, condensing hot gaseous oil, separating organic matter form inorganic matter, and washing the inorganic matter. Prior to the liquefaction step, the comminuted waste is soaked in oil in an inclined screw conveyor for wetting the comminuted waste and excluding air therefrom during subsequent steps. The liquefaction is carried out within a converter having a rotating screw for displacing the oil soaked waste therethrough during a time period approximating 30 minutes. The waste within the converter is maintained at a temperature within the approximating range of 200.degree.-370.degree. C.
