The concentration of sorbitol on bioplastic cellulose based carrageenan waste on biodegradability and mechanical properties bioplastic

Abstract

Synthetic plastic waste is the cause of environmental pollution. Therefore, innovation is needed in the manufacture of plastics using renewable raw materials, namely bioplastics. Bioplastics can be made from carrageenan industrial waste because they have high cellulose content. Bioplastics it is necessary to add sorbitol plasticizer to affect the biodegradability and mechanical properties. This study aimed was to determine the effect of sorbitol concentration in synthesis bioplastics cellulose-based from carrageenan waste on biodegradability and too determined the best sorbitol concentration in the bioplastics cellulose to geet biodegradation standards and mechanical properties. This research is experimental in biodegradability testing by adding sorbitol (0, 3, 6, 9, 12 mL) to bioplastics and Article study on the mechanical properties of bioplastics. The experimental study used ANOVA data analysis and continued with DMRT. The results of this study indicated that the effect of sorbitol concentration affected the biodegradability of bioplastics (P <0.05) with the highest value of 58.68 0.90% for seven days at a concentration of 12 mL. Based on the Article review, the optimum sorbitol concentration in production bioplastics cellulose that gets biodegradation standards and the mechanical properties of bioplastics was 3 mL.
