<p>PROBLEM TO BE SOLVED: To enable normal operate of a cement plant after the disposal of waste material of a game machine. SOLUTION: In a pinball machine, synthetic resin parts such as a top plate set 1c, bottom plate set 1d, front decoration 1e, cell board, not shown, center winning part 2b, pinwheel 2c, start port 2d, general prize port 2e, large prize port 2f, out port 2g, prize ball lamp set 2h, stop lamp set 2i, prize ball passage structure, not shown, prize ball mechanism, and control circuit unit are formed from thermoplastic synthetic resins such as ABS or polycarbonate whose temperature transition, at the time of compression and volume reduction when pinball machines abandoned from game shops are utilized for a cement plane, comes into a predetermined range. Therefore, when block-shaped volume-reduced solidified materials are formed from crushed fragments of pinball machines abandoned from game shops, synthetic resin parts in the fragments are turned from a solid phase to liquid phase in a nearly uniform temperature transition, and hence reduced-volume solidified materials can be formed, when they are fed into a rotary kiln of cement plant, in a stable state.</p> |
