ABSTRACT:
Solid lignocellulosic material is bonded together by heating and pressing at a natural wood, pH by reacting sugars, starches or both in the presence of a catalyst capable of catalyzing transformation of the sugars and starches into a solid, insoluble in water, and an alkaline buffering agent if needed, for example to make waterproof plywood or composite products from particulate wood without hydrolytic degradation of the wood.
