1. A method of producing dry processed fibreboards from resin-bonded waste composite wood products, wherein said wood products are chemically treated in a pre-heater unit of a refiner system under super-atmospheric pressure in the presence of steam to disrupt adhesive polymer bonds, formed into fibres in a subsequent disc refiner unit of the refiner system and further processed by a dry process to form fibreboards with a reduction of resin consumption by the reactivation of resin in said wood products.
