NOVELTY - Organic waste composting apparatus contains an input hopper, device for pulverizing organic waste, tank for storing pulverized material, an unit for returning the stored pulverized material, device for mixing and distributing the returned pulverized material, collected seed compost, and sawdust, and tank for fermenting the mixed and distributed mixture.    USE - The apparatus and method are useful for composting organic waste (claimed).    ADVANTAGE - The method is environmentally-friendly, improves degradability of waste to 90%, and does not produce any bad odor and leachate.    DETAILED DESCRIPTION - Organic waste composting apparatus comprises an input hopper (100), device for pulverizing organic waste added to the input hopper, tank for storing pulverized material, an unit for returning and withdrawing the stored pulverized material and inducing fermented liquefied fertilizer mixed with pig urine and aerobic microorganism, device for mixing and distributing the returned pulverized material, collected seed compost, and sawdust, tank for fermenting the mixed and distributed mixture, agitating tank for adding the fermented liquefied fertilizer with firstly fermented mixture for agitating the mixture and secondly fermenting the mixture, a maturing tank for fermenting the secondly fermented mixture third time and maturing the mixture, tank for storing matured compost, tank for selecting and packing stored compost, tank for storing leachate generated from the pulverized material storing tank, returning unit, and fermenting tank, aeration tank which receives stored and returned leachate and aerates the leachate, tank for separating solid and liquid of the aerated leachate, and processing tank for adding aerobic microorganism to the separated liquid and supplying the liquid to the fermenting tank and agitating tank. The pulverizing device comprises a first pulverizing device which performs a rough pulverization in a screw feeder type and a second pulverizing device which re-pulverizes the material pulverized from the first pulverizing device by high speed rotation using one rotational member from chain and wire. The returning unit comprises first conveyor (112), second conveyor (114), and third conveyor (116), magnetron (120) which radiates microwave and dries to maintain water content of the pulverized material to 50-65% which is installed at upper portion of the first conveyor, magnetic separator (130) which separates iron plate which is installed at the upper portion of the second conveyor, and a foreign material remover which selects and separates light foreign material by brush and a fermented liquefied fertilizer sprayer which sprays fermented liquefied fertilizer for promoting fermentation which is installed at upper portion of the third conveyor, a seed compost conveyor which is installed horizontally at an interval of 120 degrees to radial direction at interval from the third conveyor and supplies returned seed compost to the fermenting tank, sawdust conveyor which is installed horizontally at interval of 120 degrees from the third conveyor and the seed compost conveyor respectively in order to mix and supply sawdust to the returned pulverized material and seed compost at a volume rate of 1:1:1. The mixing and distributing device comprises an enclosing hopper which mixes and receives fallout and a distributor which is installed at vent of the enclosing hopper, and uniformly and evenly distributes mixture to the fermenting tank. An INDEPENDENT CLAIM is included for method for composting organic waste, which involves collecting organic waste, adding the waste into hopper, pulverizing organic waste, storing pulverized material, mixing the pulverized material with fermented liquefied fertilizer, pig urine and aerobic microorganism, mixing the pulverized material, collected seed compost, and sawdust in the ratio of 1:1:1, fermenting the mixture, agitating the mixture with firstly fermented mixture, fermenting the mixture for second time, aging the secondly fermented mixture, storing the matured compost, selecting and packing stored compost, storing leachate generated from the pulverized material, aerating the leachate, separating solid and liquid from the aerated leachate, adding aerobic microorganism to the separated liquid, and supplying the liquid to the fermenting tank and agitating tank.
