ABSTRACT:
A process is provided for producing lignocellulosic board panels. The process comprises providing lignocellulosic material and an adhesive system. The adhesive system comprises (a) a base adhesive resin and (b) an extender and/or filler material comprising sugar beet material. The adhesive system (i) retains substantial moisture in the lignocellulosic material, and/or (ii) creates a relatively higher initial viscosity, and/or (iii) maintains a substantially stable viscosity thereof over time. The lignocellulosic material is combined with adhesive system. The combined lignocellulosic material and adhesive is then formed into the lignocellulosic board panels.
