Hardness and biodegradation property of Bionole contained various size of Sugi particle were investigated to reveal that possibility of lowering price and improvement of the properties of biodegradable plastics. In the case of large Sugi particle size, hardness of the composites decreased with increasing of the volume fraction of the Sugi particle, while the hardness were almost constant in the case of the smaller particle size less than 0.6mm. The biodegradation property linearly increased with increasing particle size, then saturated when the particle size became more than 1mm. Moreover, the biodegradation property increased with increasing volume fraction of the Sugi particle.
