Abstract	Traditional plastics, mostly derived from petroleum-based sources, contribute significantly to environmental pollution due to their widespread use and inadequate disposal methods. Known for their durability, these plastics can persist for hundreds to thousands of years, leading to the accumulation of plastic waste in natural environments. Over time, they degrade into microplastics, which infiltrate ecosystems and food chains, posing threats to wildlife and human health. Marine plastic pollution is particularly alarming, with millions of tons of plastic waste entering the oceans annually. This results in ingestion, entanglement, and habitat damage for marine life. Furthermore, harmful additives in plastic production can leach into soil and waterways, causing additional ecological harm. To address these issues, bioplastics made from eggshells offer a sustainable and eco-friendly alternative. Eggshells, abundant in calcium carbonate (CaCO₃), are biodegradable and cost-effective. This study explores the production of bioplastics by incorporating eggshell powder into a biopolymer matrix composed of natural polymers like starch or chitosan, with plasticizers such as glycerol to enhance flexibility and moldability. The resulting bioplastic exhibits promising mechanical and thermal properties, making it suitable for various applications. By utilizing waste materials and decreasing reliance on petroleum-based plastics, eggshell-based bioplastics provide a viable solution for mitigating the environmental impact of conventional plastics and promoting sustainable material development. This approach not only helps to manage waste material effectively but also contributes to the reduction of plastic pollution. It represents a significant step toward a greener future by offering a practical and sustainable alternative to traditional plastics
