The increasing environmental concerns associated with persistent petroleum-based plastics have accelerated the search for sustainable and biodegradable alternatives derived from renewable resources. Among various biopolymers, starch-based plastics, particularly those obtained from potato starch, have emerged as promising candidates due to their abundance, low cost, biodegradability, and non-toxic nature. This study presents a comprehensive investigation into the synthesis, structural characteristics, physicochemical properties, and biodegradation behavior of potato starch-based bioplastics. Thermoplastic starch films were prepared using the solution casting method, employing glycerol as a plasticizer to enhance flexibility and processability. The influence of plasticizer concentration on mechanical strength, elongation, thermal stability, and water absorption was systematically evaluated. Characterization techniques such as tensile testing, thermal analysis, and Fourier Transform Infrared (FTIR) spectroscopy confirmed the formation of hydrogen bonding interactions between starch and glycerol, significantly affecting material performance. Biodegradation studies conducted through soil burial tests demonstrated rapid degradation, indicating strong environmental compatibility. However, the materials exhibited limitations such as high moisture sensitivity and relatively low mechanical strength compared to conventional plastics. To address these challenges, potential improvement strategies including polymer blending, reinforcement with fillers, and chemical modification are discussed. Overall, potato starch-based bioplastics represent an eco-friendly and sustainable alternative to conventional plastics, with significant potential for applications in packaging, agriculture, and biomedical fields, provided that their performance limitations are effectively mitigated
