FIELD: paper production; cellulose production.
SUBSTANCE: disclosed are integrated methods and systems for treating waste, which includes waste paper, wherein methods include treatment of wastes in a high pressure vessel at high temperature of processing and high pressure of process treatment to form treated wastes containing, in fact, pulp recycled into fibrous mass; unloading treated wastes from high pressure vessel; separation and dilution of after-treated wastes to dilute a portion containing, in fact, pulp turned into pulp, to solids content of approximately 1 % by weight to approximately 20 % by weight.
EFFECT: extracted fraction converted to fibrous mass and, in fact, fiber-free recovered/recyclable plastic and metals can be further separated and used as raw material in various subsequent processes.
