In 2025, researchers found that adding waste eggshells to clay bricks can cut heat conductivity by 50% and help keep buildings cooler

In a groundbreaking discovery, researchers have found that incorporating eggshells into clay bricks can reduce heat conductivity by half. This innovative approach not only addresses the global issue of waste from eggshells but also enhances insulation properties, leading to lower energy costs for households. With potential for further research to improve structural integrity, this solution could revolutionize energy-efficient building practices on a larger scale.
