(JP7275828-A)      Composting organic matter having high water content comprises: (i) fermentation and decomposition step; (ii) thermal decomposition step; and (iii) final drying. In fermentation and decomposition step, the organic matter is held in treatment tank under supply of air for 1-3 hrs. at temp. between ordinary temp. and 60 deg.C while heating. The matter is then agitated and ground into rice porridge-like state and aerobic fermentation performed. Generated gas and water vapour are extracted to outside of treatment tank to perform dehydration and drying thereof to water content of not more than 65%. In thermal decomposition step, temp. of fermentation and decomposition prod. is between 1-6 hrs. at 60-100 deg.C to cause thermal decomposition. Generated gas and water vapour are extracted to outside of treatment tank to perform dehydration and drying thereof to water content of not more than 45%. In the final step, the temp. of the thermal decomposition prod. is held for between 1-6 hrs. at temp. 100-135 deg.C to perform sterilisation. Generated gas and water vapour are extracted to outside of treatment tank to perform dehydration and drying thereof to water content of not more than 30%.    USE -   Useful for drying, decomposing and composting organic matter contg. a large amt. of water such as garbage, sludge etc..
