Beschreibung
Zusammenfassung:	PURPOSE: To obtain the subject material imparted with water resistance, biodegradable in soil, causing no natural environmental pollution, through utilization of e.g. sawdust as a sort of industrial waste, by preparing a green stock by kneading woodmeal with a special binder followed by hot-pressing the stock at high temperatures to carbonize and mold the woodmeal. CONSTITUTION: A green stock is first prepared by kneading woodmeal such as sawdust with a binder consisting of a biodegradable organic resin such as gelatin. Subsequently, the stock is hot-pressed at high temperatures to carbonize and mold the woodmeal, thus obtaining the objective material.
