Refuse, dust-bin, and dry waste products, treating.-In a process for treating town refuse and like waste material in which the bulky portions are removed, the remainder graded into coarse combustible and fine incombustible portions and the fine portion smelted with a suitable flux and cast into blocks as artificial stone, the combustion of the coarser portion is utilized to generate power and to smelt the finer portion. Coagulated slag resulting from the combustion of the coarser matter is converted into mortar by granulating, mixing with lime, contact salts, &c., grinding, and subjecting to a high temperature so as to disintegrate silicates. The slag which has not coagulated may be mixed with the mortar or in admixture with lime may be pressed to form building stones, which may be hardened by aid of steam pressure. The constituents of the refuse are separated mechanically.
