Abstract

A fibrous suspension prepared from waste paper by pulping (at 1), and cleansing by sorting in a screen sorter and/or cyclone (2), is temporarily heated before and/or during its passage through a disintegrating device (7) and prior to the separation of printing ink by flotation (8) or washing (and optically bleeching). The thickened suspension is maintained at temperatures above 85 DEG C during its passage through the disintegrating device (7). This allows types of waste paper, such as xerographic and offset-printed papers, which are difficult to de-ink to be cleaned, and therefore used for the production of fibrous material for paper manufacture.
