Method and apparatus by which waste paper contained in baled waste material (10) is soakingly impregnated with a fiber softening and swelling fluid as the initial stage of recycling baled waste material in reclaiming cellulose from the waste paper. The baled waste material is placed within a treating enclosure (12) which is sealed and placed under vacuum (39) after which a fiber softening and swelling fluid is drawn by the vacuum into the sealed enclosure penetrating throughout the interior voids of the bale contents and the swelling fluid is maintained within the enclosure in contact with the bale contents for a time sufficient to establish a swelling debondment of the waste paper fibrous matter. Following the fiber swelling debondment of the waste paper fibers, a watery fiber suspension fluid is passed through the impregnated waste material in the enclosure for producing a slurry of fluid suspended debonded fibers converted into cellulose in completing the recycling process.
