NOVELTY - Processing of refuse involves introducing refuse into a drum, stirring using several stirring blades while keeping the refuse in contact with a catalyst, disposing stirring blades upright inside the drum and differing in height, to cleave the intermolecular covalent bonds of the organic substances of therefuse by the electron-attracting function of the catalyst, decomposing organic substances of the into carbon, nitrogen, hydrogen, and other elements, and reacting hydrogen with oxygen present in the drum to yield water vapor.    USE - Processing of refuse discharged from small boats and ships, residence, school, company, cafeteria, welfare units, supermarket and fishing boat.    ADVANTAGE - The method efficiently and economically processes kitchen refuse with carbonization efficiency, without generating gases containing odorous substance, black smoke and dioxins.    DETAILED DESCRIPTION - Processing of refuse involves introducing refuse into a drum maintained at 95-120 degrees C, stirring using several stirring blades while keeping the refuse in contact with a catalyst, disposing stirring blades upright inside the drum and differing in height, to cleave the intermolecular covalent bonds of the organic substances of the refuse by the electron-attracting function of the catalyst, decomposing organic substances of the into carbon, nitrogen, hydrogen, and other elements, and reacting hydrogen with oxygen present in the drum to yield water vapor, which is discharged from steam vents together with the nitrogen, leaving carbon substance or wood chip as carbonization product in drum, and rotating drum until the carbonization product grows to a given size, and taking out the carbonization product as a treatment product and treating using fuming sulfuric acid or concentrated sulfuric acid at 160-200 degrees C. An INDEPENDENT CLAIM is included for organic refuse-processing apparatus.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic longitudinal cross-sectional view of drum of apparatus.    Drum (4)    Heater (9)    Insertion opening (10)    Lid (12)    Discharge hole (14)
