In a 2025 study, researchers fired clay bricks with 10% eggshell powder; thermal conductivity was 50% lower than in untreated bricks

Innovators are integrating eggshell waste into fired clay bricks, effectively reducing heat transfer in building structures. By using a 10% mix of crushed eggshells, thermal conductivity drops by 50%. This breakthrough not only presents a practical solution to managing landfill waste but also enhances insulation, contributing to lower energy consumption in warmer regions.
