  • Patent number: 10150227
    Abstract: A process for producing pellets or granules comprising fibres of a lignocellulousic material, for use as a feedstock in plastics manufacture, conveying in a dry or wet air stream and applying to the fibres a liquid formulation comprising one or more polymers, monomers, or oligomers, forming the fibres into a solid product, and breaking down the solid product to produce said pellets or granules. Typically the conduit conveys the fibres in a plant for manufacture of fibre board.
    Type: Grant
    Filed: November 30, 2016
    Date of Patent: December 11, 2018
    Assignee: NEW ZEALAND FOREST RESEARCH INSTITUTE LIMITED
    Inventors: Jeremy Martin Warnes, Alan Fernyhough, Charles Ross Anderson, Brendan James Lee, Michael Ralph Juergen Witt

  • Patent number: 8283389
    Abstract: Method of forming a composition comprising impregnated polylactic acid (PLA) resin beads, by impregnating PLA resin beads with CO2. The method is carried out by contacting the beads with liquid CO2, and holding the impregnated beads at a temperature and pressure that prevents the beads from foaming while allowing the level of impregnated CO2 to reduce to about 4 to 20 weight % relative to the total weight of the beads and CO2.

  • Patent number: 8012389
    Abstract: A process for producing a thermoformable fibre-plastics composite product comprising lignolcellulosic or natural fibres, particularly but not exclusively useful as an intermediate product in subsequent manufacture, comprises conveying the fibres in a dry or wet air stream and applying to the fibres a thermoplastic binding agent, and forming the fibres into a solid or semi-solid product such as a panel, which is thermoformable. In at least a preferred embodiment the process may be carried out in known plant for manufacture of medium density fibre board.

  • Publication number: 20100029793
    Abstract: A method of forming a composition of expanded polylactic acid (PLA) resin beads comprising impregnating PLA resin beads with CO2 and holding the impregnated beads at a temperature and pressure that prevents the beads from foaming while allowing the level of impregnated CO2 to reduce. The method may comprise pre-expanding the beads at a pre-expansion temperature. Promptly following pre-expansion or after a desired storage period, the method may comprise introducing the pre-expanded beads into a mould and further expanding and fusing the beads in the mould by application of a temperature greater than the temperature used for pre-expansion. Preferred moulded products include moulded blocks and shaped moulded products, especially blocks adapted to form packing material. Other preferred moulded products include convenience items such as containers including clamshell containers, pots, boxes, bowls, cups, plates and trays.
