FIELD: paper production; cellulose production.
SUBSTANCE: method of recycling waste containing waste paper includes the steps of: introducing waste into the pressure vessel, the secondary transformation of waste paper into paper pulp in the pressure vessel at elevated process temperatures and pressure for the formation of recycled waste containing substantially recycled paper pulp, then introducing cooling water into the high-pressure vessel to cool the processed waste in the high-pressure vessel to a discharge temperature below the elevated process temperature and reducing the odor emitted by recycled waste, and then unloading the recycled waste from the pressure vessel.
EFFECT: regenerated fraction of paper pulp is suitable as a raw material for the production of a wide variety of paper products, including paper napkins and paper towels.
