The present invention relates to a pulping process of waste paper containing impurities using a feed device, a debinding device, and a pulping component to produce paper and board. In order to improve the pulping and thereby produce less non-screenable impurities, this enables the use of a greater proportion of waste paper printed with water-soluble ink, including a soaking step prior to pulping.
