ABSTRACT:
Solid lignocellulosic material is bonded into a strong solid mass by treating with a liquid carrier containing an oxidant, and pressing under heat and pressure in a conventional unsealed press for a period of time sufficient to effect bonding by oxidation. Plywood formed of wood veneers is advantageously formed. Catalysts or other modifying agents may be employed with the oxidant.
