Researchers at IIT Guwahati have developed an innovative, eco-friendly, and low-cost solution to tackle industrial water pollution using biochar derived from fruit waste. This breakthrough, led by Dr. Gopal Das from the Department of Chemistry, uses pineapple crowns and mosambi (sweet lime) fibers to efficiently adsorb toxic chemicals from wastewater. The discovery presents a sustainable alternative to conventional pollution control methods. In their study, published in Chemical Engineeri
