Description

This study is concerned with detoxification technology of asbestos-containing wastes (non-scattering type asbestos wastes).The objective of the study is to get a prospect of the technology in order to start the actual operation soon as the certified detoxification process and facility based on the Minister' s Certification System in the 2006 Revision of Waste Management and Public Cleansing Law. It has been confirmed till now that asbestos wastes can be melted and be detoxified at temperatures below 1,500 degree Centigrade under the mixed-melting condition with incinerated ash of other wastes. However, the mixture ratio of confirmed asbestos waste is low with around 20% at the maximum. The higher mixture ratio of asbestos waste is desirable for practical operation. Then the verification tests with the mixture ratio up to 50% were executed in an existing ash melting facility under the condition that equipments and operation should be basically the same as normal ash melting process. As the result, asbestos was detoxified perfectly and no remaining asbestos could be found in emissions produced through mixed-melting treatment nor in residues inside the melting furnace, flue ducts and the bag-house.
