NOVELTY - The system (100) has pyrolysis reactor (150) in which biogas generated, and collection duct (160) which separates product from air including bad smell. Biogas is the methane gas, and control unit (170) controls feeding speed of transfer apparatus (120) and controls driving of solar energy concentration (140). The control unit controls thermal decomposition of pyrolysis reactor, and sewage of food is thermally decomposed in the pyrolysis reactor which provides thermal energy stored in fermenter (130) ferments by passing and ejected the domain in which fermenter is arranged.    USE - Fuel recycling system of sewage of food thrown away from home or dining room etc.    ADVANTAGE - The transfer apparatus can efficiently transfer the sewage of food to controlled speed in pyrolysis reactor, so that sewage of food is thermally decomposed.    DETAILED DESCRIPTION - The solar energy concentration and pyrolysis reactor control the feeding speed of the sewage of food that supply the sewage of food which are processed of the amount, and are supplied by the pyrolysis reactor is the single solar energy concentration. The pyrolysis reactor is arranged at the fixed region of each solar energy concentration condensing the sunlight the manifoldly is arranged. An INDEPENDENT CLAIM is included for fuel making method of sewage of food, involves thermally decomposing sewage of food moved in pyrolysis reactor and condensed with solar energy concentration thermally decomposing the sewage of food so as to collect the product in which the pyrolysis reactor arranged within the fixed region. Sunlight is concentrated, and sewage of food stored in the food waste reservoir is temporarily accommodated and fermented to the fixed region of the sunlight is the transferred sewage of food ejected from the pyrolysis reactor. The sewage of food is thermally decomposed than in pyrolysis reactor, thermal energy is provided. The pyrolysis reactor is processed by the single solar energy concentration. The product is separated from air and collected.    DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of the fuel recycling system of the sewage of food according to the embodiment of the invention.
