Lignocellulose based biofiller reinforced biopolymer composites from fruit peel wastes as natural pigment. | LitMetric
In this study, the utilization of mangosteen and durian peel wastes as bio-filler and natural pigment in biopolymer of polybutyrate adipate terephthalate (PBAT) were examined. The related research work of hybridization of both mangosteen and durian peels reinforced in biopolymer as cellulose-based bio fillers and natural pigment is rarely studied. The content variation of mangosteen powder and durian powder ranged from 0 to 30 wt% with an increment of 10. The influence of mangosteen and durian powders reinforced in PBAT on color change, morphological, chemical composition, mechanical, thermal, and rheological properties were determined. Mangosteen peel and durian peel provided dark appearance for the green composites without pre-burn of these fruit peels. It can be concluded that mangosteen peel and durian peel can be used as bio pigment and natural reinforcement material in biopolymer matrix which can reduce massive waste of mangosteen and durian peel and add value to these wastes. These black biopolymer composites can be used in applications of eco-friendly food packaging and medicine zipper packaging. The overall mechanical properties, thermal stability, and dark color of mangosteen/PBAT composites were greater than those of durian/PBAT composites. However, durian/PBAT composites presented greater thermal and rheological properties than mangosteen/PBAT composites.
