The development of biodegradable plastics offers a sustainable alternative to conventional ones, reducing environmental impact. This research focuses on the fabrication and characterization of biodegradable plastic films derived from large-leafed mangrove (Bruguiera gymnorrhiza) starch, chitosan, and clove essential oil (CEO) as an antioxidant additive. Glycerol was used as a plasticizer, while carboxymethyl cellulose (CMC) and carrageenan were incorporated as thickeners. The effects of glycerol (2.7–9 ml), chitosan (4–6% m/m), and CEO (0–8% m/m) concentrations on mechanical properties, morphology, and biodegradability were examined. Fourier-transform infrared spectroscopy confirmed the successful incorporation of chitosan and CEO. Scanning electron microscopy (SEM) revealed surface roughness and cavities due to incomplete chitosan dissolution. The optimized formulation (3% starch, 5 ml glycerol, 5% chitosan, and 5% CEO) exhibited superior mechanical properties, with a tensile strength of 710.98 MPa, Youngs modulus of 582.65 MPa, and elongation at break of 121.4%. Soil burial tests demonstrated complete degradation within 14 days. These findings highlight the potential of mangrove starch-based bioplastics for food packaging and eco-friendly applications.

This research successfully developed biodegradable plastic films from mangrove starch, chitosan, and clove essential oil.The optimized formulation demonstrated promising mechanical properties and a rapid degradation rate in soil.These findings suggest the potential of mangrove-derived bioplastics as a sustainable alternative to conventional plastics for applications like food packaging.Further research should focus on optimizing material blending techniques and exploring industrial scalability for commercial production.

Based on the findings of this study, future research could explore the use of different mangrove species to assess their starch properties and suitability for bioplastic production. Investigating the impact of varying concentrations of clove essential oil on the antioxidant activity and long-term stability of the bioplastic films is also crucial. Furthermore, research should focus on scaling up the production process and evaluating the economic feasibility of mangrove starch-based bioplastics compared to existing biodegradable alternatives. This includes assessing the environmental impact of large-scale mangrove starch extraction and the potential for integrating this bioplastic production into a circular economy framework. Finally, exploring the potential of combining mangrove starch with other biopolymers to enhance its mechanical properties and broaden its application range would be a valuable avenue for future investigation.
