METHOD FOR PRODUCING SOLID FUEL USING PAPER SLUDGE AS RAW MATERIAL, AND METHOD FOR PRODUCING SANITARY TISSUE PAPER USING SOLID FUEL USING PAPER SLUDGE AS RAW MATERIAL

摘要

PPROBLEM TO BE SOLVED: To reuse paper sludge discharged in a production process of sanitary tissue paper. PSOLUTION: The problem is solved by compression processing the paper sludge of which the solid content is pulp fiber of 100% discharged in a process of producing the sanitary tissue paper and containing no filler so as to reduce the moisture content to 60 wt.%, and further reducing the moisture content to 40 wt.% and molding and solidifying the paper sludge with a pelletizer so as to form the solid fuel.
