Starch based bioplastic from cassava peel

Researchers at the University of North Sumatera in Indonesia investigated the production of starch based bioplastics from cassava peel reinforced with microcrystalline cellulose (MCC) using sorbitol as plasticizer.
The results showed improvement in tensile strength with higher MCC content compared to non-reinforced bioplastics. This could be mainly attributed to the strong hydrogen bonds between MCC and starch. On the contrary, the addition of MCC decreased the elongation at break, density and water uptake. The highest tensile strength value was obtained for bioplastic with MCC content 6% and sorbitol content 20%. An article about the research is published in the Journal of Physics.
