The efficient use of lignocellulosic residue generated from bio-ethanol production is important for transition into a sustainable society. The proportion of lignin depend on plant species and hydrolysis reactivity of enzymatic saccharification treatment in bio-ethanol production. If poly(lactic)acid(PLA)green composites were prepared with lignocellulosic residue, they have merit as carbon-neutral materials. In this study, to investigate the effect of the residue surface and lignin fraction on the mechanical properties of the PLA composites, first, the effect of the hydrolysis reaction time of the lignocellulosic residue was analyzed. Field emission scanning electron microscopy analysis showed microspores on the residue surface, which increased with the hydrolysis reactivity. The PLA composites were prepared with injection molding, and their tensile strength increased with the saccharification treatment time, possibly because of physical anchoring due to the presence of microspores on residue.
