The green composite has attracted special interest recently. From the viewpoint of the effective utilization of waste wood, we proposed the composite composed of woodchips as the matrix material, bamboo fibers as the reinforced fiber and the biodegradable resin as the adhesive. The composite was formed a mixture of those materials into correct shape by press at the appropriate temperature. In this paper, in order to improve the strength of the composite, the surfaces of woodchips and bamboo fibers were modified by the alkali treatment. By examining the bending strength of the composites, it was found that the alkali treatment was effective in order to improve the bending strength of the proposed composite. Especially, it was clarified that the high bending strength was obtained in the case of combination of woodchips with the alkali treatment and bamboo fibers without the alkali treatment.
