The European Polymer Congress, organized by the European Polymer Federation (EPF), stands as the most significant European conference in the field of Polymer Science and Technology. As the flagship event of EPF—a non-profit organization that includes nearly all National Polymer Societies in Europe—the conference has grown substantially since its inception in 2001. With 24 full members and 4 associate members, the biennial congress attracts an increasingly diverse and expanding participation. The theme for EPF 2025, “Polymers for a Sustainable Future,” is of special significance in the current era, addressing the urgent need for sustainable solutions in various industries.
