The ReShell transforms eggshells into modular biodegradable bricks by converting discarded shells into building elements that interlock like traditional bricks while returning to the earth at the end of life. The process begins with cleaning, drying, and grinding eggshells into fine powder. Natural additives such as red clay for strength, bran for texture, and straw for flexibility are blended to create a composite that is lightweight, durable, and compostable. The interlocking design makes assembly simple and versatile, supporting applications from interior walls and furniture to exterior facades inspired by multifunctional Korean design principles.

This concept addresses construction waste challenges by transforming a common organic byproduct into a sustainable alternative. The final product is strong enough for temporary structures yet biodegradable, ensuring that it leaves no harmful residues once dismantled. ReShell illustrates how material innovation and circular design can converge to reduce waste, advance sustainability, and redefine how architectural and design projects approach construction.
