(CN1260337-A)   NOVELTY - Converting organic waste by thermophilic fermentation comprising the provision of a predetermined amount of porous material as a fermentation medium, its mixing with organic waste that naturally contain microrganisms, heating to 45-100degreesC, allowing microbial symbiosis and the continuous proliferation and growth inside the porous material for a predetermined time is new.    USE - For converting organic waste using thermophilic fermentation (claimed). The organic waste includes animal manure, animal fecal matters, animal carcass, food wastes, food processing waste, green waste, and/or kitchen waste, to useful end product e.g., organic fertilizer or animal feed supplements with comfortable smell (claimed). The porous material is chosen from charcoal, coal, oyster shell, clam shell, sea shell, egg shell, rice husk, corn husk, bone, wood, feather, glass, ceramic, gypsum, porcelain, clay, diatomaceous earth, starch polymer, minerals, and/or metal (claimed).    ADVANTAGE - The method reduces processing time to less than 12 hours. It produces useful end product, such that farmers save fertilizer or animal feeds expense(s) and earn extra income by selling organic fertilizer or animal feed supplements. It prevents secondary pollution from using trucks to move waste(s) to another site. It also reduces the burden of landfill and waste handling expenses. It requires low capital investment on equipment.    DETAILED DESCRIPTION - Conversion of organic waste involves thermophilic fermentation comprising:    (a) the provision of a porous material as a fermentation medium having a predetermined amount of thermophilic microorganisms. The thermophilic microorganism include(s) Actinomycetales,Pseudomonadales, Eubacteriales or fungi;    (b) the organic waste is mixed in with the porous material in a mixing digester, heated to, and maintained at 45-100degreesC by provision of an extremal heat source allowing the continuous proliferation and growth of the organisms;    (c) allowing the microbial symbiosis and mutualism reaction to accelerate a speed of fermentation and decomposition of the organic waste until it is converted to useful end product within a predetermined period of time.
