PROBLEM TO BE SOLVED: To provide a waste utilization system with which a waste is fed to a box body as it is, is indirectly heated to stably and inexpensively form high-quality charcoal, the charcoal is treated as a recycling material so that the waste is effectively used. SOLUTION: Charcoal is inexpensively formed so as to convert only a waste to charcoal. The waste is fed to a box body and heated indirectly by applying heat generated outside the box body to the box body. Therefore, the heating temperature of the waste is constant to efficiently form high-quality charcoal having a uniform structure. The inexpensive and high-quality charcoal is used as a recycling material. Accordingly, the waste is converted into high-quality charcoal to effectively use the waste. COPYRIGHT: (C)2007,JPO&INPIT
