  • INTERMEDIATE PRODUCT FOR MANUFACTURING LIGAIN POLYMERS AND IT'S USE IN MANUFACTURING REAGENTS FOR MAKING COMPOSITE MATERIALS FROM PLANT FIBERS, WATERPROOF PAPERS AND CARDBOARDS, AND THERMOSETTING PLASTICS FROM DERIVATIVES
    Patent number: 6410674
    Abstract: The invention relates to an intermediate product for manufacturing polymers of lignin derivatives from the pulp industry, made by treating the lignin derivatives with phenol oxidizing enzymes in the presence of oxidation agents, characterized in that the lignin derivatives are (a) subjected to enzyme treatment for more than 3 hours in the presence of air, or (b) subjected to enzyme treatment for more than 10 minutes while air or oxygen is being passed through them, or (c) oxidized by treatment with chemical oxidation agents. The intermediate product is used in manufacturing polymers of lignin derivatives from the pulp industry, fiber-reinforced thermosetting composite materials from plant fibers, waterproof papers and cardboards, and thermosetting plastics from lignin derivatives.

  • Process for the treatment of oxygenated exhaust gases
    Patent number: 4977090
    Abstract: A process for the decontamination of oxygenated gases comprises growing a mycelium of pocket rot mushrooms on a substrate and bringing the exhaust gas into contact with the mycelium. The substrate comprises a waste material, such as agricultural, forestry, or fishery wastes, or wastes from the wood pulping industry. The mycelium and the substrate are shaped into body forms of a desired configuration which promote contact of the oxygenated gas with the mycelium in particular environments.
