Patent ID: 7160713

Claim:
A method for biologically oxidizing organic matter waste, said method comprising: directing the organic waste to a top end of a reaction vessel ( 1 ), wherein the reaction vessel is substantially filled with biologically unoxidizable spheres ( 7 ), upon which the surfaces of the spheres the organic matter to be oxidized is present as thin layers, directing oxidizing air regulated in terms of heat and humidity to the reaction vessel below an oxidizing zone of the reaction vessel, and above a perforated floor, said floor precludes the spheres from falling into a waste receiving area disposed below the reaction vessel, but allows the treated waste to pass into the receiving area; discharing exhaust gas from the top end of the reaction vessel and scrubbing the exhaust gas, discharing substantially dry oxidized matter from the receiving area of the reaction vessel, and transporting the spheres ( 7 ) from the bottom end to the top end of the reaction vessel ( 1 ) to control the rate at which the spheres gravitate downward through the reaction vessel.
