PROBLEM TO BE SOLVED: To provide a method for producing a granular carbonized material having a high strength of the granules after its granulation ad to the granules after its dry distillation, hardly becoming powder and being effectively utilized as a snow-melting agent, an activated carbon, or the like. SOLUTION: This method for carbonizing a vegetable waste comprises granulating the vegetable waste after drying it, followed by dry distilling. The vegetable waste is dried to <=50 wt.% water content, granulated and then subjected to a dry distillation with a rotary kiln heated from its outside to obtain a granular carbonized material. Otherwise, the vegetable waste is dried to <=60 wt.% water content, added with a clay mineral by 20-40 wt.% in dry weight ratio, then granulated and then subjected to a dry distillation with a rotary kiln heated from its outside to obtain a granular carbonized material. |
