On Episode 3 of Mastering Sustainability, we welcome Heidi Sanborn, founding director of the National Stewardship Action Council (NSAC) and the California Product Stewardship Council (CPSC), two organizations that advocate for equitable circular economy. Heidi joins us for a fiery, candid chat about about the evolution of Extended Producer Responsibility (EPR) legislation, California’s new SB54 law, and the role of consumers in driving legislative change.
