Biodegradable polymers can solve environmental pollution which is the problem of commercial plastics. Poly(L-lactide) (PLA) is synthesized by the polymerization of L-lactide which is produced by the pretreatment of Kenaf. Cellulose and lignin, the main components of Kenaf, are also blended with PLA to make the composite film. The remaining hemicellulose produces C5 chemicals such as pentanediol through a chemical catalytic conversion process. As such, the process in this study is particularly important because it can produce biomass-derived chemicals without the loss of any components of biomass. For the composite film, cellulose and lignin at the ratio extracted from Kenaf are added to PLA. It is confirmed that as the amount of additives increases, the crystallinity of the film decreased and the elongation of the composite film increased. The hydrolysis test of the composite film is also carried out. The composite film can be used by modifying the content of additives according to the use.
