The students, according to the Nominating Committee, “developed a novel approach to adsorb lead in industrial wastewater by utilizing eggshells, a locally abundant bio-organic waste material.” By mixing groud-up eggshells in a liquid lead solution, the students successfully removed more than 90% of lead pollutants from liquid waste. The process can be applied in both small-scale industries and large industrial operations.
