<P>PROBLEM TO BE SOLVED: To improve a processing efficiency of beverage production residues to reduce a processing expense, and to utilize properties caused by residues to provide a high value-added product. <P>SOLUTION: The paper blending material is produced by subjecting beverage production residues having a water content of 60-80 mass% to an anaerobic treatment for 50 hours or more and less than 1000 hours. The functional paper is produced by preparing a pulp slurry containing the paper blending material and a paper pulp, and making the pulp slurry into paper. The functional paper is used as a shading paper, a shielding sheet or the like. <P>COPYRIGHT: (C)2012,JPO&INPIT |
