NOVELTY - Fermentation-decomposition of organic waste by mixing organic waste with bed material formed by growing microbes in composite containing bark or saw dust. The process is performed with moisture content adjusted to 55-60% at 70-80degreesC, for 144-168 hours with constant stirring. Subsequently the fermenting organic material stirred for 96-120 hours without adjusting the temperature.    USE - For processing organic waste generated from live stocks such as cattle and pig, tough fur, tough internal organs and larger bones. And also for organic refuse ejected from sludges, wood pieces,    ADVANTAGE - The method enables complete processing of organic waste, without leaving any residues. The unpleasant odor of the decomposed components are effectively removed, without polluting the external environment. The method effectively processes organic waste, especially waste generated in business area and domestic waste.    DETAILED DESCRIPTION - Method of fermentation decomposition of organic waste involves fermenting organic waste in tank comprising a decomposition tank and bed material. The bed material is formed by growing microbes (which is innocuous to men and animal), such as aerobes of soil and water, in composite containing bark or saw dust. Organic waste is supplied continuously, in a fixed amount and mixed with the bed material for growing of microorganisms. The Accumulation-fermentation (AF) of organic waste is carried out with moisture content adjusted to 55-60% at 70-80degreesC, for 144-168 hours with constant stirring. Subsequently the fermenting organic material by stirred for 96-120 hours without adjusting the temperature, so as to completely decompose the organic waste.    An INDEPENDENT CLAIM is also included for apparatus for fermentation-decomposition of organic waste, which comprises elliptical shape fermentation tank equipped with adjusting unit (1a), fermentation decomposition tank (1b,1c), implanted bed material adjusting tank (1d). The decomposition tank (1) comprises waste material insertion opening (10) equipped in an injection tube, inserted in side wall, at fixed intervals. A reverse U-shaped hood covers and provides the top. The center (peripheral wall surface) portion of the fermentation adjustment tank is equipped with an air supply pipe (11) . The decomposition tank accumulates implanted bed material on the outer sublayer containing sand, clippings and upper layer. A radiating pipe (14) (require number) is provided on the fermentation-decomposition tank (1b), in circular direction. A movable unit (21) equipped in the top surface of the decomposition tank supplies air and water. A pollutant removing apparatus (23) is equipped in a exhaust port (16), removes odor generated during decomposition, through a steam separator (18).
