Abstract

Bioplastics based on natural materials offer an innovative solution to reduce the negative impact of conventional plastics on the environment. This study evaluated bioplastics made from banana peels processed with various plasticizers, such as glycerol, chitosan, sorbitol, polylactic acid polymer, sodium metabisulfite, and tapioca starch. The focus was on mechanical properties, such as biodegradability, tensile strength, and elongation. Banana peels, with a starch content of 59%, proved ideal for bioplastics, with a degradation time of 4–84 days in soil. Bioplastics with 2% glycerol degraded in 4 days, while those with sodium metabisulfite degraded in 84 days. Glycerol increased flexibility but decreased tensile strength. The combination of 1.5% glycerol and tapioca starch produced the highest tensile strength of 66.39 MPa, while the highest elongation was 115.43% with 2% glycerol. This study highlights the potential of banana peel bioplastic as an environmentally friendly alternative, and further research is recommended to optimize the combination of plasticizers to make the bioplastic stronger, more elastic, and antibacterial by combining glycerol, sodium metabisulfite, and tapioca starch. These findings are important for the future development of sustainable and applicable bioplastics.

Abstract

Plastic is a synthetic polymer derived from petroleum and contains hazardous additives, such as heavy metals and chlorine. The use of cassava starch as the main ingredient in bioplastics, a natural polymer, can be an environmentally friendly and biodegradable solution. However, cassava starch has limitations, such as its hydrophilic nature, poor mechanical strength, and poor stability. To address these issues, plasticizers such as glycerol and sorbitol are used to improve tensile strength, flexibility, and moisture resistance. Meanwhile, the addition of fillers can increase tensile strength, thermal resistance, and reduce hydrophilic properties, thereby improving the stability of bioplastics. Therefore, this review of biodegradable plastic research focuses on the use of cassava starch with the addition of various fillers that can be degraded by various processing techniques. To analyze the quality of these plastics, various testing methods are carried out, including physical, mechanical, thermal, and biodegradability tests, as well as structural and morphological analysis. The results of this research provide innovations that can be developed by making biodegradable plastic from cassava starch by combining a mixture of cassava starch with the addition of PLLA and CMC fillers and acetic acid as well as the addition of a combination of glycerol and sorbitol plasticizers.
