Effect of carbon for enhancing degradation and mechanical properties of bioplastics composite cassava starch/glycerin/carbon

Plastic product is one of the global problems due to the processes of degradation it takes thousands of years to decompose. Scientists in the world proposed a solution by using bioplastics. In this study, we synthesis bioplastics from cassava starch mixed with glycerin at various concentration (3%, 6%, 9%) and carbon at various concentration (0.5%, 1%, 1.5%). The biodegradability of the bioplastics was studied and provided the moisture absorption, tensile strength, and the structural properties by X-ray diffraction (XRD). The high concentration of glycerin (≥ 6%) would accelerate the degradation process 2 times higher than the lowest concentration. The degradation process and the mechanical properties increased with increasing the amount of carbon in bioplastic.
