<p>PROBLEM TO BE SOLVED: To provide a method for carbonization treatment of waste that produces a coal material product in a high yield by continuously and stably carbonizing a material to be treated which is made of inexpensively manufactured waste and to provide a carbonizing device.SOLUTION: The method for carbonization treatment of waste includes: a step of crushing a plastic waste and an organic waste, respectively, and mixing, compressing and heating the crushed wastes to produce a solid matter; a step of preheating a semi-open type furnace body to a temperature of 300°C or higher; a step of continuously charging a material to be treated from the charging part of the furnace body pre-heated to a temperature of 300°C or higher; a step of continuously supplying to the furnace body oxygen of less than the theoretical oxygen amount for the total amount of the solid matter to be charged; a step of conveying the material to be treated which has been charged from the charging part toward a discharge part; and a self-sustained combustion/carbonization step of simultaneously performing temperature maintenance of the furnace body by combustion corresponding to the amount of oxygen for the material to be treated which is supplied to the preheated furnace body and carbonization of the material to be treated by dry distillation due to the shortage of oxygen in the theoretical oxygen amount.</p> |
