Ammonia and Critical Minerals Recovery Workshop

August 20-21, 2024
Washington, DC

This workshop sought to accelerate the pace of technological innovation toward recovery of high energy-value materials from wastewater that can directly enter existing supply chains, as well as reduce energy demands and greenhouse gas (GHG) emissions associated with conventional sourcing and waste stream treatment. High energy-value materials are nutrients (i.e., ammonia and phosphorus) and critical minerals in varied wastewaters (e.g., from municipal, livestock, industrial, and mining sources). Areas to be explored are selective adsorbents and membranes, and novel reactions and process designs that advance recovery. Additional areas include approaches to evaluate technical, economic, environmental, and technology-to-market feasibility of recovery approaches. 

Participants had the opportunity to (i) discuss progress in relevant technical areas, (ii) identify key technical challenges and possible solutions, (iii) evaluate technology to market opportunities, (iv) contribute to performance metrics, (v) network with stakeholders, and (vi) share experiences in the field.
