NOVELTY - Livestock carcass processing system comprises a crushing unit for crushing livestock carcasses, a base, a mixing drum installed on the base for stirring biodegradable material introduced along with crushed livestock carcasses and is provided with a slope, a stirring unit for stirring while rotating biodegradable material introduced along with crushed livestock carcasses supplied from the crushing unit and is equipped with a driving unit installed on the base for rotating the mixing drum, and a composting unit for composting biodegradable livestock carcasses supplied from the stirring unit.    USE - Used as a livestock carcass processing system.    ADVANTAGE - The system reduces environmental pollution caused by gas containing hazardous substances and bad smell, decomposes livestock carcasses within a short period of time, improves degradation rate of the livestock carcasses and land utilization rate, and is economical.    DETAILED DESCRIPTION - Livestock carcass processing system comprises a crushing unit for crushing livestock carcasses, a base (210), a mixing drum (230) ratably installed on the base for stirring biodegradable material introduced along with crushed livestock carcasses and is provided with a slope at its own center axis of rotation, a stirring unit (200) for stirring while rotating the biodegradable material introduced along with crushed livestock carcasses supplied from the crushing unit and is equipped with a driving unit (240) installed on the base for rotating the mixing drum, and a composting unit for composting biodegradable livestock carcasses supplied from the stirring unit by hydrolyzing. The mixing drum and the composting unit are formed with an inlet port and an outlet port for introducing and discharging the livestock carcasses. The inlet port and the outlet port of the mixing drum and the composting unit are optionally open and close and are installed with a hazardous material removing unit for removing by collecting hazardous materials having bad smell. The hazardous substance removing unit comprises a suction unit for sucking the hazardous substances having bad smell, a plasma generating unit for generating plasma and removing hazardous substances present in the fluid sucked by the suction unit by communicating with the suction unit, and a catalytic unit for removing hazardous substances present in the fluid passing through the plasma generating unit by communicating with the plasma generating unit.
