Summary:The primary sludge from a pulp and paper plant wastewater containing high concentrations of fibre was dewatered and used as part of the feed for the production of hardboard. Pilot-scale tests with feeds containing up to 50 per cent sludge were carried out and the properties of the resulting hardboard evaluated by water adsorption, swelling and bonding strengths. A feed with 20 per cent sludge proved optimal. Savings on wood pulp and sludge disposal amounted to 18 U.S. dollars per tonne of hardboard produced. This approach was then successfully applied in a full-scale plant.
