Method of producing fibreboard

U.S. Patent Number: 5618482

Abstract: A method of producing a fiberboard having improved mechanical properties such as water uptake (swelling), tensile strength perpendicular to the surface (IB), modulus of elasticity (MOE), and modulus of rupture (MOR) of the resulting fiberboard. The method includes providing a slurry of lignin-containing wood fiber material, adding a phenol oxidizing enzyme system, forming a mat of the wood fiber material, and pressing the formed mat by applying heat and pressure.
