Abstract
A wastepaper treatment method and system which combines the pulping and sorting in a pulping drum (10) with a following wet-strength processing, performed with high mechanical intensity, e.g., in a pulper (20). With the easily pulping paper materials being separated already from the drum (10) in a fines fraction (3), particular advantages result in terms of quality and economy.
