When turning wastes (G) into a solid body (S) through processes performed in a waste receiving pit (1), first crusher (3), first screen (5), second crusher (7), second screen (9), mixing-storing reactor (13), compression molding machine (17), and drying-neutralizing reactor (19), treatment of wastes with the application of an optimum alkaline earth metal oxide such as CaO to any one or a plurality of processes in said waste receiving pit (1), first crusher (3), second crusher (7), and mixing-storing reactor (13) enables the provision of a solid body (S) effective as a raw material of environmentally clean fuel or material for construction work. An optimum quantity of CaO to be added can be found on the basis of a quantity of organic substance (U) calculated from analysis and measurement of water content (W), a quantity of plastics (P), that of inorganic substances (M), and that of re-usable substances (W) that constitute the wastes (G) with an index of 100. Further, feed-back of an appropriate quantity of wastes having passed the mixing-storing reactor (13), mixing-deaerating reactor (15), or drying-neutralizing reactor (19) to the mixing-storing reactor (13) ensures a solid body (S) far more uniform in quality. By mixing the solid body (S) thus made from wastes with a natural fuel, an excellent hybrid fuel can be obtained. When an intermediate product obtained in the course of the above treatment of wastes into the solid body (S) is directly charged into an incinerator (37), clean burning is possible. |
