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.
Behavior of Advanced Materials and Emerging Contaminants in the Soil-Plant Continuum
Organizing Divisions: AGRO | ENVR
Modern agriculture is increasingly shaped by two parallel trends: the intentional application of advanced materials—such as biopolymers and functionalized nanomaterials—and the unintentional influx of emerging contaminants, including PFAS, micro/nanoplastics, and pharmaceuticals, which are delivered through biosolids, reclaimed water, and agrochemicals. Once in the field, these substances migrate through the soil–plant continuum, entering crops via both foliar and soil pathways. Understanding their uptake mechanisms, in-planta translocation routes, and biochemical or redox-driven transformations is essential for accurate environmental risk assessment and for designing safer, more effective agricultural technologies. Talks in this session will highlight recent advancements in deciphering the pathways of uptake, translocation, and transformation of materials intentionally or unintentionally introduced to soil and plant crops. Additionally, research on predictive models and life-cycle tools to inform the development of regulatory frameworks for these materials in agriculture will be encouraged. This interdisciplinary session targets researchers in environmental science, environmental and analytical chemistry, materials science, soil geochemistry, plant physiology, and agronomic engineering, aiming to bridge mechanistic insights with practical solutions for sustainable agriculture.

Enriching Chemistry Curricula with Contemporary Research
Organizing Division: CHED
Chemistry is a constantly evolving science, shaping industries, research, and technological advancements. However, many cutting-edge topics such as nanotechnology, computational chemistry, electron microscopy, molecular structure, and chirality are often underrepresented in high school curricula and may not be thoroughly explored in undergraduate programs. Integrating contemporary scientific research into chemistry curricula offers students a unique opportunity to engage with the nature of science and the scientists behind current discoveries. By connecting foundational concepts with emerging discoveries, students gain deeper insights into the open-ended nature of scientific inquiry and the many unanswered questions that drive research forward.
This symposium will explore how contemporary scientific discoveries can be integrated into high school and undergraduate chemistry programs to spark curiosity and deepen engagement. Participants will also discuss challenges such as limited curriculum time, complex subject matter, and the need for educator training to ensure effective implementation.
We invite educators, researchers, and curriculum developers to share their experiences, innovative approaches, and ongoing studies. Presentations will highlight selection criteria for advanced topics, pedagogical strategies, and professional development programs that support educators in bridging foundational principles with emerging research. Through collaboration and shared insights, this symposium aims to shape a more dynamic and future-oriented chemistry education, fostering a deeper appreciation for the discipline among students and teachers alike.
Environmental Implications and Applications of Artificial Intelligence and Machine Learning
Organizing Division: ENVR
The rapid advancement of artificial intelligence (AI) and machine learning (ML) has opened new frontiers in environmental science and engineering, offering transformative tools to address critical challenges in pollution control, resource management, and environmental sustainability. AI/ML technologies provide innovative avenues to tackle complex environmental problems with high chemical specificity and spatial-temporal precision, spanning contaminant transport and chemical transformation pathways, optimizing water/wastewater treatment processes, enabling resource recovery, and enhancing environmental monitoring systems. Conversely, the environmental footprint of large-scale AI/ML infrastructure—including high energy demands, water use in data centers, and material intensity of hardware—raises important questions about sustainability and lifecycle impacts. A growing need has emerged for responsible development and deployment of AI/ML systems that consider their own environmental (chemistry-related) consequences, including emissions, waste streams, and interactions with air, water, and soil systems. This symposium welcomes research papers that describe recent advances in the context of environmental implications and applications of AI/ML.

Methane: Chemistry of a Greenhouse Gas
Organizing Division: 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.
