  • Process for pulping waste paper containing impurities
    Publication number: 20060011314
    Abstract: The invention relates to a process for pulping waste paper containing impurities, used in the production of paper and board, with a feed device, a dewiring unit, and a pulping section. In order to improve pulping and thus generate less non-screenable impurities, which would make it possible to use larger proportions of waste paper with water-soluble inks, a liquid penetration stage is included in the process before pulping.
