The "PFAS 2024" conference was held from October 29 to 30, 2024, in Baltimore, Maryland, to discuss insights into the regulatory situation surrounding PFAS and the technical and economic challenges associated with the implementation of bans. Concerns about health risks and the long persistence of PFAS in the natural environment have led to an expansion of regulations, particularly in Europe, in recent years. This conference focuses on new alternatives and alternative technologies that do not contain PFAS, promoting a transition towards sustainability in the industry. The scope includes additives and other substances that may contain PFAS used in the plastics industry, extending beyond the fluoropolymer market to include release agents, foaming agents, processing aids, anti-blocking agents, flame retardants, and anti-corrosion coatings. PFAS is also used as an additive to uniformly disperse PTFE particles in liquids.
