Engineers turn coconut shells into road material; 12.5% biochar makes asphalt stronger and more heat-resistant
Engineers found that adding 12.5% coconut shell biochar makes asphalt stronger and more heat-resistant. The study, published in Next Materials in 2026, showed this waste material helps roads stay stable in high temperatures. Researchers S. Mahalakshmi, Revathy Jayaseelan, and Gajalakshmi Pandulu used this method to improve overall pavement performance and durability.
