METHOD OF TREATING ASBESTOS-CONTAINING WASTE MATERIAL

摘要

A method of asbestos treatment in which an asbestos-containing waste material of arbitrary configuration can be detoxified completely and safely. The method of asbestos treatment comprises impregnating an asbestos-containing waste material with an acid so as to cause at least the asbestos at the surface of the waste material to be nonasbestous and further treating the treatment product in a cement production plant. In particular, the treatment in a cement production plant is a fusion treatment by means of a cement kiln. Therefore, not only can the asbestos-containing waste material be detoxified completely and safely but also a cement reusing the waste material can be produced. ® KIPO & WIPO 2009
