1. An organic waste processing method for fermenting organic waste and turning it into compost, comprising the steps of: providing a plurality of processing tanks, each processing tank being formed of a conical vessel disposed with its narrow end as a bottom of the vessel and being sealed at its top end with a lid that includes a material inlet, said tank further including an outlet located on an uppermost surface of a peripheral wall of the tank, a drive motor, a rotatable shaft connected to the motor, and stirring blades installed on the shaft, the motor, shaft, and blades being constructed extending in a diametral direction of the tank such that centrifugal force generated by the blades allows a part of the material being processed to be mixed in an upward swirl in the tank and to be discharged out of the tank through the outlet, wherein the inlet of each tank vessel in processing succession is provided at an elevation lower than that of the outlet of the preceding tank vessel, and processing organic waste aerobically with microorganisms mixed therein in processing succession through said plurality of processing tanks.
