WASTE TREATMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a waste treatment method in which a thermally decomposing and gasifying process and the melting process of ash and slag components are efficiently carried out for plastic waste by a relatively simple structure. SOLUTION: The drying process and the thermally decomposing and gasifying process of the plastic waste and the melting process of the ash and slag components are continuously carried out in a one cylindrical rotary kiln. The moving direction of the plastic waste is opposed to the flowing direction of high temperature gas as a heating source.
