Close-up of Re:Shell biodegradable bricks made from recycled eggshells, showing their earthy beige tones. The interlocking modular design is visible, with natural textures from loess and wheat bran giving the bricks a tactile, organic surface.
Re:Shell is a groundbreaking biodegradable building material developed by the Living Design Lab at Seoul National University. By reimagining discarded eggshells as functional bricks, the project merges sustainability, cultural heritage, and modular design innovation.
From Food Waste to Biodegradable Bricks
Eggshells, rich in calcium carbonate, are typically thrown away as food industry waste. Re:Shell collects these shells from local bakeries and restaurants, grinds them, and mixes them with loess, wheat bran, and straw. The result is a lightweight, durable composite that can be shaped into bricks. Unlike conventional construction materials, these bricks are fully biodegradable, naturally decomposing in soil without leaving harmful residues.
The Modular System and Cultural Roots
The bricks use an interlocking design system that allows for creative assembly. From façades and partition walls to modular furniture and mobile tables, the bricks adapt to different design contexts. Inspired by Korean traditions of adaptable living spaces, Re:Shell connects cultural values with cutting-edge material science.
Circular Construction in Action
By sourcing eggshells locally, Re:Shell reduces transport emissions while turning a waste stream into a valuable resource. When their use cycle ends, the bricks can safely return to the earth, embodying the principles of a closed-loop material system. This circular approach directly addresses the ecological challenges posed by traditional construction waste.
Expanding the Potential
Current research at Seoul National University focuses on improving water resistance and structural strength while keeping biodegradability intact. These advancements could expand Re:Shell’s applications across both interior and architectural projects.
Conclusion
Re:Shell demonstrates how overlooked by-products can become vital resources for future cities. By transforming eggshell waste into modular, biodegradable bricks, the Living Design Lab offers a new blueprint for sustainable construction. It’s an inspiring reminder that innovation often begins with rethinking the materials we already have.
Self-healing concrete is a groundbreaking material in construction that automatically repairs cracks using methods like microbial, chemical, or polymer-based healing. This innovation increases structural longevity, reduces costs, enhances safety, and promotes sustainability. Its applications range from bridges to residential buildings, promising a more resilient and cost-effective future in construction.
Ultrasint® PA6 MF is a polymer powder specifically engineered by BASF and Forward AM Technologies GmbH for demanding industrial applications. The “MF” stands for mineral-filled, which highlights its enhanced mechanical properties compared to standard PA6 powders.
Autex Acoustics excels in creating sustainable, high-performance acoustic materials for varied environments, including offices, theaters, and restaurants. Their products, made from recycled plastics, enhance sound control and aesthetics. With a focus on performance and sustainability, Autex offers panels, fabrics, and custom solutions, ensuring top-quality, eco-friendly acoustics.
In 1937, a remarkable innovation was captured by British Pathé: an Italian inventor had developed a method to turn ordinary milk into yarn. The archival footage documents each stage of the process, from laboratory experiments to industrial production, ultimately producing a fabric that looks and feels like wool. This pioneering attempt at material innovation reveals how early 20th-century science was already pushing the boundaries of sustainable design.
