Our Work

The Rich Earth Institute recycles urine into fertilizer, eliminating water pollution and supporting sustainable farming.

The Institute conducts original research on the safety and efficacy of urine-derived fertilizer, using its first-in-the-nation facility in southern Vermont to conduct field trials and develop urine processing and handling technologies. In collaboration with academic, industry and government stakeholders, the Rich Earth Institute is pioneering pragmatic, sustainable solutions at the intersection of  agriculture and sanitation.
