A novel method to reuse paper sludge and co-generation ashes from paper mill

摘要

The purpose of this study is to develop a technology for reusing the paper sludge and co-generation ashes generated by the paper industry. The study will include the following: (1) employing granulation technology to produce a light-weight aggregate with a specific gravity less than 1.0 from paper wastes sludge, and a light-weight aggregate with a specific gravity less than 1.5 from co-generation ashes;(2) employing compounding technology to mix co-generation ashes with ceramic materials, and then to make it into constructional bricks through forming and sintering processes.
