  • Method for pyrogasification of organic waste
    Patent number: 8308912
    Abstract: A method for pyrogasification of organic wastes that employs a vertical furnace filled with metal masses in the shape of metal toroids (2) previously raised to a high temperature (500 to 1100° C.) and organic materials to be pyrolyzed. It also employs a furnace for heating toroids transported by an Archimedes screw driven by a gear motor, as well as a separator for recovering the mineral residues, whereby separation between the toroids and residues is effected with the aid of a screen and an Archimedes screw driven by a gear motor.
