RECYCLE PROCESSING OF BALED WASTE MATERIAL

摘要

An improved method of processing baled waste material by enclosing the bale within a closed chamber (12) and subjecting the chamber and contained bale to multiple pressure environmental conditions, while submerging the bale in a debonding fluid. The impregnated bale contents are allowed to soak for a period after which the bale is subjected to pulping agitation to initiate separation of the swollen fibers without significant damage to the fibers. The agitated bale contents are separated in a screen separator (41) into a slurry and a reject mass of higher degree contaminated, unswollen fibers and contaminants. If the reject mass contains a significant degree of recoverable fibrous material, it is compressed into bale form (54) and again subjected to a multiple pressure liquid impregnation treatment in a closed chamber and, thereafter, is subjected to similar recycling operations in separating out the fiber pulp slurry.
