| Abstract Scope |
The demand for rare earth elements (REEs) in energy and defense technologies necessitates a resilient US supply chain. Developing unconventional REE resources can offer diversified alternatives that supplement primary extraction. This study explores strategies to recover REEs from coal ash, a large but logistically challenging resource. We developed a geospatially explicit resource database and compared different technology options for ash processing, separation, and site management. The RELOG tool was used to optimize logistics and production networks. A scenario analysis examined the impact of policy, technological, and economic interventions. Our results show that strategic facility placement and technology integration can significantly reduce costs. Coupling supply chain development with legacy site reclamation can be mutually beneficial. Coal ash supply chains can also produce chemicals, non-REE critical materials, and cement additives, potentially increasing economic and strategic benefits. This study demonstrates how progressive industrial practices can be implemented to improve material security. |
