Research Area: Resource Recovery

Our Objective

Transition the wastewater treatment industry to one focused on resource recovery (starting with nutrients) with the vision that most, if not all, materials in wastewater can be commoditized. Wastewater is a renewable resource. Get the [[Nutrient_Recovery|related report]].


The TERRY-Ag tool provides a high level, conceptual cost and energy estimation for nutrient recovery from agricultural wastes/sludges or from municipal sludges, as well as an estimate of the potential fertilizer production and revenue from recovery processes. The tool includes factsheets for the various technologies that are available for nutrient recovery. A series of five tutorial modules allows users to learn to use the TERRY-Ag tool with ease.
