The Cycle of PFAS and its Evolving Landscape: Webinar Series
Have you ever wondered what per- and polyfluoroalkyl substances (PFAS) are, why they exist, and how concerned you should be? This webinar series will explore the lifecycle of PFAS, discussing alternative applications, health implications, and the regulatory landscape. Expert speakers will “pull back the curtain,” unmasking the realities of PFAS and providing attendees with a clearer understanding of how, where, and why these chemicals appear in daily life.
Thank You to Our Presenting Sponsor
The American Chemistry Council’s mission is to advocate for the people, policy, and products of chemistry that make the United States the global leader in innovation and manufacturing.
The American Chemistry Council and its members believe chemistry plays an integral role in solving our world’s sustainability challenges. They are therefore committed to advancing safe, innovative, effective, and economically viable chemical products and technologies that are key to unlocking sustainability solutions.

Part 1: The Cycle of PFAS
March 24th | 1:30 - 3:00 PM ET
This session will explore the functional properties that make PFAS valuable and trace the pathways by which they enter and move through the environment. Experts will examine how PFAS interact with compost, organics, and other biomaterials, and discuss the resulting environmental implications. The session will also assess the roles these chemicals serve in products and the feasibility of available alternatives. Attendees will leave with a foundational understanding of how PFAS persist and circulate throughout our materials management systems.
Part 2: The Evolving Landscape of PFAS
March 25th | 1:30 - 3:00 PM ET
As awareness of PFAS grows, so does the urgency to evaluate what comes next. This session will explore the practical, regulatory, and market considerations shaping the transition away from PFAS. Speakers will provide an overview of the evolving policy landscape at the state and federal levels, highlighting recent actions, proposed regulations, and emerging compliance requirements. The discussion will explore how these policies could influence manufacturing practices, waste and recycling systems, and the evolving roles and obligations of key stakeholders.

Peter R. Jaffe, Princeton University

Peter R. Jaffe, Professor, Department of Civil and Environmental Engineering, Princeton University
Peter Jaffé joined the faculty of Princeton University in 1985 and is the William L. Knapp ’47 Professor of Civil Engineering, in Department of Civil and Environmental Engineering. He is a member of the NIEHS Center for Environmental Health Sciences at the Environmental and Occupational Health Sciences Institute, at Rutgers. His research has focused extensively on biological and chemical pollutant dynamics in porous media; simulation and analysis at the watershed scale of soil contamination processes and nutrient cycling; nitrogen cycling at the watershed scale; and dynamics of trace metals and radionuclides in sediments, wetland soils, and groundwater. Areas of current emphasis include biological defluorination of per- and polyfluorinated alkyl substances (PFAS). This effort ranges from gaining novel insights into the defluorination mechanism, applications such as bioremediation of aqueous firefighting foam (AFFF) impacted sites, the development of bioreactors for to treat PFAS impacted matrices, and the identification and use of the key enzymes that play a role in the PFAS defluorination process.
