1. A method for ozone sterilization of waste material, comprising the steps of:
- providing a tank including a top surface, a bottom surface and a substantially cylindrical side wall that define a substantially hollow chamber, wherein the tank includes a first inlet, a second inlet, a third inlet, and an outlet, wherein the first, second and third inlets are positioned within the substantially cylindrical side wall and the outlet is positioned within the bottom surfacereceiving the waste material in the tank via the first inlet;
receiving ozonated liquid and ozone gas in the tank via the second inlet;
mixing the waste material and the ozonated liquid within the tank to produce a slurry;
pumping the slurry out of the tank via the outlet and into a pump;
cutting the slurry into reduced sized particles in the pump;
continuously re-circulating the slurry from the pump to the tank via the third inlet until the slurry is sterilized;
guiding the slurry from the third inlet along the bottom surface of the tank to the outlet after re-circulation via a deflector plate positioned on the bottom surface of the tank at an angle and height to allow recirculation, and recirculating for the circumference of the tank wall via positioning of the third inlet behind the deflector plate with respect to the outlet at a predetermined height and position; and
filtering the sterilized slurry.

Abstract
A system for ozone sterilization of waste material, includes a tank configured to receive waste material, ozonated water, and ozone gas. The system further includes a pump coupled to the tank to receive the waste material and the ozonated water from the tank and form a slurry. The pump includes a cutter assembly to reduce a particle size of the slurry through cutting. Additionally, the system includes a circulation loop coupled between the tank and the pump to receive the slurry from the pump and re-circulate the slurry to the tank until the slurry is sterilized. A method for ozone sterilization of waste material is also disclosed.
