NOVELTY - The system for treating a waste material comprises a mixer for combining a bulking agent with the waste material, a first sorting device for removing inorganic material, a first phase compositing area located in an enclosed area for receiving the sorted waste material on a floor, a second sorting device for removing residual inorganic material and the bulking agent from the partially composted sorted waste material, and a transition area for receiving partially composted sorted waste material from the first phase compositing area on a floor.    USE - Useful for treating a waste material.    ADVANTAGE - The system reduces waste and avoids odor for a long time.    DETAILED DESCRIPTION - The system for treating a waste material comprises a mixer for combining a bulking agent with the waste material, a first sorting device for removing inorganic material, a first phase compositing area located in an enclosed area for receiving the sorted waste material on a floor, a second sorting device for removing residual inorganic material and the bulking agent from the partially composted sorted waste material, a transition area for receiving partially composted sorted waste material from the first phase compositing area on a floor, a second phase compositing area for receiving the compostable organic material from the transition area on a floor, and a curing phase compositing area for storing composted organic material. The waste material has predominant amount by weight of a compostable organic material. The inorganic material has a dimension exceeding a predetermined amount from the bulked waste material. The first and second phase area has a first and second network of drains. The first and the second network of air ducts imbedded in the first and the second phase compositing area floor. The first and the second network of drains lead to a cistern and the air ducts in operative engagement with a blower for blowing air out of the air ducts. The first phase area comprises unit for increasing a humidity of the sorted waste material and inoculating the sorted waste material with a composting bacteria. A first and a third network of vents are used for collecting noxious gases emitted by the composting bacteria when compositing the sorted waste material and transmitting the emitted gases to a bio-filter. The second and the third phase area comprises unit for increasing a humidity of the compostable organic material and re-inoculating the compostable organic material with the composting bacteria. The first sorting device comprises a trommel. The second sorting device is a star screener and a ballistic separator. The third sorting device is a star screener. The curing phase compositing area comprises the third sorting device for removing residual bulking agent from the composted organic material prior to storage. The transition area is located in an enclosed area. The transition area comprises a third network of drains and air ducts imbedded in the transition area floor. The third network of drains are leading to a cistern and air ducts in operative engagement with a blower for blowing air out of the third network of air ducts. The transition area comprises adjusting unit for a chemical composition of the compostable organic material. The compostable organic material removes the residual inorganic material and the bulking agent from the sorted waste material. The second phase compositing area is located in an enclosed area and comprises a third network of vents for collecting noxious gases emitted by the composting bacteria and transmitting the emitted gases to the bio-filter. The blower blows air cyclically out of the first-, the second- and the third network of air ducts. Temperature sensor for detecting a temperature of the sorted waste material. The blower blows air out of the first network of air ducts with a duration and frequency dependant on the temperature. The humidity increasing unit and the inoculating unit comprises sprinklers arranged above the floor. The sprinklers are in operative engagement with a water source under pressure containing the compositing bacteria. The water source under pressure comprises a pump in operative engagement with water retained in the cistern. The water retained in the cistern contains the compositing bacteria. INDEPENDENT CLAIMS are included for:    (1) a method of treating a waste material;    (2) a method of compositing waste material; and    (3) a method of mixing waste material.
