Japanese Patent JP3572021

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a solvent for forming slurry from waste-containing organic matter such as kitchen waste discharged from a comparatively small-sized business office or the like so that the waste can be stored for a fixed period of time near the waste generating source to collect the waste at each fixed period of time and treat the waste finally at final treatment facilities, can be prevented from going rotten during the storage period of time to prevent a bad smell from emitting and can be handled easily and to provide a method for recovering the solvent. SOLUTION: The waste-containing organic matter is crushed 25. One or more solvents selected from monoterpenes such as limonene, acetate such as isopentyl acetate, propionate such as benzyl propionate and butyrate such as ethyl butyrate are added to the crushed waste so that the crushed waste is formed into slurry 40 while the oil and fat content, protein and the like in the crushed waste are dissolved. The crushed waste is restrained from going rotten by a microbe. The waste of a slurry state is separated into solid content and liquid content by centrifugal separation or the like. The separated liquid content is heated so that the moisture content is vaporized and separated, which is then heated furthermore so that the solvent is recovered by vaporization and separation.
