The present invention relates to a method for manufacturing fuel using livestock manure, sewage sludge, and food waste and, more particularly, to a method for manufacturing fuel using livestock manure, sewage sludge, and food waste, wherein the livestock manure, sewage sludge, and food waste can be recycled and can be used as low-priced heating materials. The present invention comprises: a raw material pulverizing step of preparing chaff and waste wood powder, providing the chaff and the waste wood powder to a pulverizer, and pulverizing the chaff and the waste wood powder to be 6 to 14 mm in size; a compressing and drying step of supplying 50 to 70 parts by weight of mixed raw material of one or more among unprocessed livestock manure, sewage sludge, and food waste to a compressor, primarily removing moisture, supplying the mixed raw material to a drier, inputting 15 to 35 parts by weight of chaff and 15 to 35 parts by weight of waste wood powder, which have been prepared in the raw material pulverizing step, and drying the mixture by heating; and a molding step of drying fuel and molding the fuel to have a diameter of 4 to 5 mm and a length of a 18 to 22 mm. |
