Abstract
The examination committee was organized to provide technological advice to resolve the problem of environmental pollution caused by industrial waste materials, which were dumped illegally on Teshima Island, Kagawa Prefecture. This article reports a summary of the result of an examination by this committee from July 1997 to February 2000.
First, an impermeable wall will be constructed on the North coast of the disposal area to prevent polluted water from flowing out to sea. 600,000 tons of industrial waste will be excavated and moved to Naoshima Island. These waste materials will be melted and transformed into slag at a new melting furnace in Naoshima, at a capacity is 200 tons per day. The slag will be reused as aggregate in concrete. Comprehensive environmental preservation measures and full environmental monitoring of sewage and emission gas is planned in Teshima and Naoshima.

Key words: Teshima, technological examination committee, industrial waste treatment
