A three phase method of treating solid waste to preserve the resource value of the constituent materials. The first phase includes steps to separate ferrous metal from the waste stream, shred and grind the solid waste to generally uniform small particles, dry the waste material to remove essentially all free moisture and render the waste biologically inert, compact the dried waste material into uniform high density blocks, and encapsulate the compacted blocks; included in the second phase are 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 the secondary processing utilizing combination of vibratory conveyors, melt separation assemblies; and the third phase includes steps to further separate and refine selected recovered materials by chemical treatment. |
