Focal Point on Bioplastics in Japan

One of the most abundant base materials for bioplastics is cellulose, which is responsible for the structural rigidity of plant cell walls. But many plant-derived bioplastics are made from starch. Starch, however, is often sourced from materials that could be used as food, which means it could compete for important agricultural land and contribute to problems of fertilizer pollution. As a result, many researchers in Japan are now looking more seriously at cellulose.
