Advancing Resource Recovery for Critical Minerals
Organizing Divisions: ENVR | GEOC
As global demand for critical minerals—such as rare earth elements, lithium, cobalt, and nickel—continues to surge, there is an urgent need for innovative solutions to secure sustainable and reliable supplies. These metals are essential to the green energy transition, modern electronics, and advanced manufacturing, yet their extraction and processing are often accompanied by significant environmental, social, and geopolitical challenges. Resource recovery from industrial residues, electronic waste, and other secondary sources offers a promising pathway to alleviate supply risks and reduce environmental impacts associated with traditional mining. Advancing the science and engineering of critical metal recovery also aligns with circular economy principles, driving innovation across the entire supply chain. This symposium aims to bring together researchers, industry practitioners, and policymakers for a vibrant discussion on recent advances in resource recovery technologies and opportunities for critical minerals. We invite abstracts that address topics such as: (1) Characterization and distribution of critical minerals in unconventional sources and waste streams; (2) Novel extraction technologies to recover critical minerals from waste; (3) Novel technologies and processes for separation and purification of critical minerals; (4) Techno-economic assessments in critical minerals recovery; and (5) Life cycle assessment and environmental sustainability for critical minerals recovery.

Enabling Circular Economy through the Sustainable Conversion of Waste Streams into Valuable Resources
Organizing Division: ENVR
This symposium aims to explore innovative scientific and engineering solutions that advance a sustainable future for both humanity and the environment. A central theme is enabling a circular economy through the sustainable conversion of waste streams (including wastewater, greenhouse gases, solid wastes, etc.) into valuable resources. By shifting away from the traditional linear 'take-make-dispose' model, the circular economy promotes a closed-loop system that emphasizes reducing, reusing, and recycling materials to extend their lifecycle and value.

Methane: Chemistry of a Greenhouse Gas
Organizing Divisions: ENFL | ENVR | GEOC | I&EC
Methane (natural gas) is an insidious greenhouse gas, accounting for about 1/3 of the recent increase in Earth's surface temperature. Present at about 2.00 ppm in Earth’s atmosphere, and rising faster than at anytime since record keeping began in the 1980s, the infrared absorption cross-section of methane is much larger than carbon dioxide. Methane is a valuable fuel and industrial feedstock, having a global market value projected to be $120 billion in 2025 and grow 5-10% per year. Use of fossil fuels contribute 120 million tons (Mt) of methane emission into the atmosphere each year. Methane’s savior is a mean atmospheric lifetime of about ten years, providing a near-term opportunity to mitigate atmospheric warming and climate disruption. This session includes methane sources and sinks, atmospheric measurements and modeling, understanding methane releases and leaks, and methodology for reducing methane emissions along the fossil fuel supply chain. Aligned with U.N. Sustainable Development Goals 7, Affordable and Clean Energy, and 13, Climate Action.
