In 2025, researchers fired clay bricks with 10% eggshell waste; thermal conductivity fell 50%, turning food waste into a more insulating building material

Researchers discover that adding 10% eggshell waste to fired clay bricks significantly reduces thermal conductivity by 50%, transforming food waste into an effective insulating building material. This innovative approach offers potential benefits for energy efficiency in buildings, particularly in hot climates.
