Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for treating shredder dusts by increasing its added value for extending the scope of its utilization while utilizing an existing device, further simultaneously treating the thermal decomposition residue after a gasification by the thermal decomposition for aiming at the utilization of them as resources. SOLUTION: The method for treating the shredder dusts is provided by performing the gasification by the thermal decomposition of the shredder dusts, washing the thermally decomposed gas, mixing with coke oven-generated gas, purifying and utilizing. The shredder dusts can be thermally decomposed for gasifying by utilizing e.g. a shaft furnace type gasification melting furnace in a waste material-treating facility. The gas washing can be done by a flushing utilizing an ammonia water generated in the coke oven. Also, after the ammonia water flushing, an electric dust collection is performed. Also, tar collected in washing the thermally decomposed gas can be mixed with the tar collected from the coke oven-generated gas and utilized. COPYRIGHT: (C)2003,JPO
