Résumé / Abstract

Waste paper coated fiberboards are chopped into chips and then pulped according to a chemical-thermal procedure, which dissolves the wood structure. The liquid remaining after the separation of the fibre material (pulp) is retained as waste liquor and can be used as extender for wood adhesives. The pulps are used as raw material for medium density fiberboards (MDF). The mechanical properties of medium density fiberboards were determined. There are no significant differences between the strength properties of boards derived from industrial virgin fibres alone and from industrial fibers substituted by 50% of the chemically treated waste paper coated MDF. However, the thickness swelling of boards derived from industrial fibers mixed with fibers from a chemically treated waste MDF are significantly lower.
