Abstract: The present invention describes a fungal modified chitosan adhesive for binding a fibrous material and the method of producing the adhesive. The adhesive is produced by providing a chitosan containing raw material; a fungal growing medium; a fungal culture; mixing the raw material, the growing medium and the fungal culture together to produce a suspension; incubating the suspension to produce a broth comprising a modified chitosan solid, an at least partially-consumed medium liquid and a fungal residue; separating the modified chitosan solid from the liquid and the fungal residue, and dissolving the modified chitosan solid to produce the adhesive resin.

Abstract: A method of producing a strand board having an average density of between 450 and 550 Km/m3 by providing a first set of strands having a moisture content of between 25 and 45% based on the dry weight of said strands and a second set of strand having a moisture content of between 5 and 7% based on the dry weight of said strands and forming a lay-up having a core layer formed of strands from the second set of strands sandwiched between a pair of surfaces layers each formed from strands of the first set. The lay-up is then pressed between heated platens into a consolidated panel having an average density of between 450 and 550 Km/m3 by closing the platens to the thickness of said consolidated panel in less than 30 seconds and raising temperature the said core layer to 100° C. in less than 35 seconds without increasing the core gas pressure above 0.17 MPa.

Abstract: Low density composite wood panels are manufactured from a feedstock comprising wood wool strands of high average slenderness ratio and high average aspect ratio, and low bulk density. The feedstock wool strands are blended with a resin binder typically in the range of 3 to 5 percent by weight and a hot wax in the range 1 to 2 percent by weight and formed into a mat. The mat is hot pressed with steam injection to effect curing of the resin. The low density panels may include on one or both of their major faces a wood veneer layer. The wood wool strands typically comprise wood of the aspen or jack pine species.
