Abstract: An improved method of processing baled waste material containing waste paper having fibers contaminated to various degrees for recovering usable cellulosic fiber pulp from the bale in which the bale contents are impregnated with a fiber swelling and debonding fluid by enclosing the bale within a closed chamber and subjecting the chamber and contained bale to multiple pressure environmental conditions, that preferably includes a vacuum, while submerging the bale in the debonding fluid. The impregnated bale contents are allowed to soak for a sufficient period that the lesser degree contaminated fibers become swollen after which the bale is subjected to a sufficiently low degree of pulping agitation as initiates separation of the swollen fibers without significant damage to the fibers and which does not significantly decrease the sheet size of higher degree contaminated bonded fibers and other contaminants. The agitated bale contents are separated in a screen separator into a pulp containing slurry and a reject mass of higher degree contaminated, unswollen fibers and contaminants. If the reject mass contains a significant degree of fibrous material, it is compressed into bale form and again subjected to a multiple pressure liquid impregnation treatment in a closed chamber after which the multiple pressure impregnated bale is subjected to the same or similar recycling operations in separating out the fiber pulp slurry.
