PROBLEM TO BE SOLVED: To recycle paper-making refuse generated in a paper-making process and disposed as a waste by converting the refuse to a solid fuel. SOLUTION: The ratio of the solid fuel is set so that paper-making refuse, a waste plastic and waste paper account for 40-60 wt.%, 30-50 wt.% and 5-15 wt.%, respectively. An amount of heat of the solid fuel is regulated by specifying the ratio of paper-making refuse, a waste plastic and waste paper. As the solid fuel is prepared by mixing a waste plastic and waste paper with paper-making refuse generated in a paper-making process, paper-making refuse, which has found no other way for disposal than discarding, can secure a new way for reuse. By adjusting the composition of the solid fuel so that paper-making refuse, a waste plastic and waste paper account for, for example, 50 wt.% (40-60 wt.%), 40 wt.% (30-50 wt.%) and 10 wt.% (5-15 wt.%), respectively, the solid fuel is set to have an amount of heat almost equal to that of coal thereby permitting the solid fuel readily employable for a general boiler and the like.
