Abstract The environmental impact of petroleum-based plastics has driven the pursuit of sustainable alternatives such as bioplastics derived from renewable resources. Hence, this study explores the development of biodegradable bioplastics using starch extracted from locally available taro ( Alocasia macrorrhizos ) locally known as Borkosu and potatoes in northeastern part of India. The starches were extracted through wet milling and sedimentation techniques and combined with plasticizers such as glycerine and vinegar to prepare bioplastic films. A series of formulations were tested to assess the impact of varying composition of glycerine/vinegar on mechanical properties and film quality. Taro starch, with its high amylopectin content and local abundance, presents a viable nonfood crop for bioplastic production. Potato starch, with well-established processing advantages, complements taro in hybrid formulations. This study highlights the potential of blending both starches to improve mechanical strength, processability, and water resistance, thus, offering a scalable, low-cost, and eco-friendly alternative for disposable plastic applications in rural and industrial contexts.
