Abstract

The environmental concerns of petroleum-based plastics, including their non-biodegradability, contribution to pollution, and reliance on finite fossil resources, have motivated growing global interest in biodegradable alternatives, with starch-based bioplastics emerging as a promising solution due to their renewability, biodegradability, cost-effectiveness, and compatibility with existing processing technologies. This review synthesizes recent developments, challenges, and analytical techniques related to starch-based bioplastics. It examines the physicochemical properties of starch, modification methods such as plasticization, blending, and chemical treatments, and key production techniques including extrusion, injection molding, and 3D printing. Mechanical, thermal, and barrier properties are evaluated through standardized testing approaches, and the influence of various additives is discussed in detail. While starch-based bioplastics show potential in packaging, agriculture, and biomedical applications, they face limitations related to moisture sensitivity, thermal instability, and production scalability. Analytical tools like Scanning Electron Microscope, X-ray Diffraction, and Thermogravimetric Analysis provide critical insights into structural and functional optimization. The review also addresses sustainability metrics through life cycle analysis and outlines key barriers to commercialization. Overall, starch-based bioplastics represent a viable path toward a circular economy, contingent upon continued innovation and policy support.
