This grant supports awards for the second of three Sustainable Minerals, Metals, and Materials (SM3) Scialog conferences, to be held in September 2025. The SM3 Scialog brings together top early-career faculty from diverse fields to develop collaborative research projects addressing critical challenges in material sustainability. At these conferences, scientists work together in small teams to craft research proposals that are then presented and reviewed, with the most promising ideas receiving seed funding. The first SM3 conference in 2024 was exceptionally successful. Participants generated a record of 36 research proposals, with seven selected for funding. The Sloan Foundation supported four of these projects focused on reducing resource-intensive mining processes, utilizing minerals from unconventional sources, and improving mineral separation techniques. This grant will support 10 awards to SM3 Scialog Fellows on winning proposals, with each Fellow receiving $66,000. While some projects may go on to secure additional funding in the future, the primary goal of this effort is building lasting networks among early-career researchers. A final SM3 conference is planned for 2026.
