ABSTRACT:
Municipal refuse is treated to produce fuel particularly useful for the operation of a power generating boiler by a process which is characterized by shredding of the as-received material, separation of the light materials prior to pulping of the heavy materials, and ultimate separation from the pulped materials of the inorganic constituents, after which the remaining slurry of predominantly organic materials is dewatered to produce a particulate fuel. The light materials separated after the initial shredding operation are then directly combind with the dewatered organic residue from the pulping operation to effect further reduction in the moisture content of the resultant mixture. The invention is especially applicable to communities where the garbage and trash are collected separately, with the lights produced by shredding and air classifying the trash being added to the fuel product produced by pulping the garbage.
