  • Abstract: This project examines whether eggshell waste can be recycled into a strong and eco-friendly bowl. Eggshells, rich in calcium carbonate, were cleaned, crushed into powder, and combined with agar, water, and glycerin to form a moldable mixture. After boiling, shaping, and drying, the final product was tested for strength, durability, and water resistance. Results showed that the bowl became hard after drying, could withstand moderate weight (up to 20 coins without damage), and resisted cracking from low-height drops. It also showed some resistance to water, though it softened over time. The project successfully demonstrates that eggshell waste can be repurposed into useful products, supporting sustainability and reducing household waste in line with SDGs on responsible consumption and climate action.
