The purpose of this study is to produce biodegradable biomass board using rice straw for substituting the wood products and plastic products. Dried rice straw after harvest was cut into chips, which was soaked in water at room temperature for 96 hours. The mechanical refining of rice straw was conducted using beat refiner. The refined rice straw was formed into board by hot presser. The mechanical properties of biomass boards were measured by tensile test. The results showed that the rupture stress of bioma...
