In this paper, a method for drying a variety of untreated fish waste, and carbonizing the dried material under a reduced pressure, thereby achieving a more stable and economical treatment for the waste materials, and an apparatus for performing the method were discussed. We proposed updated speedy dryer which have continous input and screw conveyer. If we use updated speedy dryer, fish waste can be changed to useful feed and liquid composts. With the method and apparatus, it is possible to separate condensate water from a high-temperature and high-humidity air stream and discharge the condensate water having passed through a purifying operation, while utilizing the residual air stream as burning air required for drying and carbonization of waste material. This has the effects of preventing from generation of contaminants and environmental pollution while reducing fuel costs, and a carbide, obtained via the drying and carbonization of the waste material, is available into solid fuel having superior burning efficiency. The condensate water can be used to deodorants.
