  • Hardening of bonding systems
    Patent number: 11306228
    Abstract: The present invention provides bonding systems comprising a formaldehyde-based (urea-/melamine-/phenol-/resorcinol-formaldehyde or other combination) and/or a polymeric isocyanate resin system composition for bonding ligno-cellulosic materials to form panels and/or shaped products, which contain a resin hardener, also referred to as resin catalyst, characterised in that the hardener is activated by heat.

  • Production of high added value products from resin-bonded waste composite wood products
    Patent number: 6841101
    Abstract: A method of producing dry processed fiberboards 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 fibers in a subsequent disc refiner unit of the refiner system and further processed by a dry process to form fiberboards.

  • Production of high added value products from wastes
    Publication number: 20030056873
    Abstract: A process for producing fibreboards by recycling waste composite wood products through a conventional dry fibreboard continuous process in which modification is effected in the pre-heater and/or refining steps which provides recycled fibres constituting at least 20% by weight of the final fibre content of the resultant fibreboards.
