Reject Handling

The dewatering of rejects to highest dry contents represents a fundamental process for the paper industry from an economic as well as ecological viewpoint. Especially in waste paper preparation plants but also in mechanical and chemical pulp mills. With maximal dry contents, we minimize volume and weight. Hence we meet the customer demands such as the reduction of transport and landfill charges. Furthermore, high heating value to achieve constant and ecological incineration without additional heating.

Most modern paper mills are among our customers for complete systems that produce RDF from their rejects. Generally, the treatment of rejects from waste paper processing plants is integrated into the paper mill. The same processes may, however, be used by specialized waste disposal companies. In short, the separation process of valuable constituents such as metals and impurities is of importance.


  • Adjustment to customer requirements
  • Maximum dryness
  • High capacity of up to 250 BDTPD
  • Defined particle size
  • A defined level of Fe and non-ferrous contamination
  • Storage and transportation of RDF

Rejects from chemical and mechanical pulp mills

Bellmer thickens rejects from chemical and mechanical pulp production, such as knobs, knots, chives, are thickened by our thickener AKSE®. In sequence, we dewater the rejects further on with our screw press AKUPRESS AS/AX to reach even higher dry contents. In general, both machines, thickener and screw press, are adjusted to the individual application requirements. For instance, we adapt our units in terms of the different materials used and comply them with the latest employment and emissions protection standards. In short, we take our customer requirements and needs serious.
