Abstract:
A three phase method of treating solid waste to eliminate hazards and preserve the resource value of the constituent materials, separating and recovering the constituent materials, and productively using those constituent materials, includes, in the first phase, steps to separate ferrous metal constituents from the waste stream, shred and grind the solid wastes to generally uniform small particles, dry the waste material to remove essentially all free moisture and render the wastes biologically inert, compact the dried waste materials into uniform high density blocks, and encapsulate the compacted blocks; includes, in the second phase, steps to return the compacted blocks to uniform particles and separate the combined constituent materials on the basis of density, with primary processing utilizing a series of fluidized bed and cyclonic separator assemblies and with secondary processing utilizing combinations of vibratory conveyors, melt separation assemblies, and the like; and includes, in the third phase, steps to further separate and refine selected recovered materials by chemical treatment, prepare selected materials for reuse, and apparatus and method of producing a composite material by extruding a hollow body, pumping a slurry of particles and uncured binder material into the interior of the hollow body, and curing the binder material to create a solid core surrounded by an outer layer.
