Scott Cassel

Scott Cassel has over 35 years of experience in the public, private, and nonprofit sectors solving materials management problems. As CEO of the Product Stewardship Institute (PSI), he has led the movement that built the capacity for product stewardship in the US over the past two decades. Scott also developed the facilitation process that PSI uses for stakeholder engagement and consensus-building, which laid the foundation for the passage of most of the nation’s extended producer responsibility laws, including the first industry-run, government-mandated paint stewardship program. Prior to founding PSI in 2000, Scott served as the Director of Waste Policy and Planning for the Massachusetts Executive Office of Energy and Environmental Affairs, where he developed and implemented solid and hazardous waste management policies and programs. He has written extensively on product stewardship topics, including the product stewardship chapters in the Future of Packaging: From Linear to Circular and the Handbook on Household Hazardous Waste. Scott holds a master’s degree in Environmental Policy and Dispute Resolution from the Massachusetts Institute of Technology, and a bachelor’s degree in Geology and Environmental Studies from the University of Pennsylvania.
