PROBLEM TO BE SOLVED: To obtain activated carbon useful as a building material, aggregate for health-promoting instrument, a cleaning agent for city water, etc., by the reutilization of industrial wastes with little generation of toxic gas at a low cost by baking industrial waste containing carbohydrate at a specific temperature. SOLUTION: An industrial waste containing carbohydrate (e.g. wood chips or animal and vegetable residues generated from wood manufacturing industry, removal of work, etc., concretely the residue in food preparation industry, sawdust, chaff, beer cake and bean curd refuse) is burned at a temperature not to cause the combustion of carbon, e.g. at 600-800 deg.C to cause little loss of the furnace and suppress the generation of toxic gases originating from chlorine, sulfur, etc. |
