The overarching goal of the proposed work is to develop and demonstrate a self-sustaining selective nutrient capture and recovery unit. Three objectives are introduced in the video, including 1) Design selective nano-adsorbents, 2) Develop electro-assisted regeneration, and 3) Pilot-Scale validation.

The poster highlights the work to date and its relevance to P3. Selective nutrient capture benefits people by preventing harmful algal blooms in drinking water sources and recreational areas to improve the quality of people’s lives. Simultaneous recovery benefits prosperity by recovering nutrients as essential agricultural fertilizers to maximize economic benefits. The combination of capture and recovery benefits the planet by transforming nutrient cycles from linear extract-and-emit schemes to closed recycle loops, which reduce emissions from energy-intensive nitrogen-fixation (N) and conserve natural resources by reducing phosphorus-mining (P).
