The session addresses the friction between emerging environmental mandates and commercial operations. Managing Partner Lynn L. Bergeson will join Senior Toxicologist Lindsay A. Holden, alongside L. Claire Hansen and Catherina D. Narigon, to evaluate the impact of California’s "Truth in Recycling" law and the European Union’s Packaging and Packaging Waste Regulation. The panel intends to provide a comparative analysis of domestic and international frameworks, focusing on how companies can mitigate legal risk while adapting to novel product stewardship obligations. Attendees will explore the technical and legal challenges of defining microplastics, the influence of recent litigation on market access, and the practical strategies required for long-term due diligence. The discussion will cover the implementation of the EU Microplastics Regulation and the broader implications of state-level initiatives currently reshaping the plastics value stream.
