Research article:  Environmental Science and Technology.  Researchers at Georgia Tech have developed a method to harvest rare earth elements (REEs) directly from coal waste. Anuja Tripathi, a postdoctoral researcher, co-developed this innovative method to recover critical rare earth elements from this industrial waste. Working alongside professors Ching-Hua Huang and Xing Xie, Tripathi transformed what she once viewed as a childhood nuisance into a valuable resource. It offers a way to extract the essential materials needed for modern technology from America’s massive stockpiles of coal fly ash.
