Abstract
Illegally dumped waste in Teshima includes a wide variety of substances such as ASR(Automobile Shredder Refuse), incineration ash, sludge, and soil deriving from granite, which permit some inclusions in the melted slag. Some treatments are shown to minimize the inclusions in the slag for the use of aggregate authorized by TR(Technical Report). They are, removal of slag containing soluble silicate followed by crushing and separation of aluminum and copper from crushed slag. The removed slag in appropriate for the aggregate is crushed and melted again to make them available, so that all the melting product may be recycled.
