Abstract
Municipal refuse is treated to produce a particulate mixture consisting essentially of its organic constituents substantially free of inorganic materials, the particles in the mixture being of less than a predetermined maximum particle size, and the mixture also being characterized on a volumetric or weight unit basis by (a) substantial homogeneity of component materials, (b) substantial uniformity from the standpoint of distribution of particle sizes, (c) substantially uniform moisture content, and (d) substantially uniform fuel value. This mixture is then converted to compacted lump fuel, e.g. pellets, briquettes or cubes, by first drying to an appropriately low moisture content, e.g. 20% or less, a minor fraction of the pellets being recycled as the fuel for effecting the desired drying.
