 Green-ed sorbents are a type of low-cost material derived from agricultural sources, such as fruits, vegetables, foods, agricultural residues, and other low-cost sources.

Green-ed sorbents can also be used to treat wastewater, reducing the amount of chemicals needed to treat the water. This article was authored by George C. Keezes and Margueritas Castiglou.
