Reimagining Wastewater

wastewater treatment plant

Untreated discharges of human excreta threaten aquatic ecosystems and human health. Moving toward a system in which every waste stream is mined for maximal value and minimal environmental impacts is hampered by adherence to centralized wastewater treatment, which exhibits a slow rate of adoption, is poorly suited for remote and resource- constrained communities, and requires considerable energy and greenhouse gases emissions.

Funding Year: 
North America
Research Areas: 

This project will advance a novel biological-electrochemical treatment approach that can be adapted widely, requires less energy and emissions, and produces ammonium sulfate fertilizer and potable water. The research team will investigate this solution at molecular, process and systems scales, with the aim of accelerating its adoption by attracting interest from wastewater utilities and sanitation service providers.
