The “CIRCULAR FOAM” project aims to achieve plastic circularity, focusing on rigid PU foams used in refrigerators and construction. Its consortium includes various stakeholders needed for a closed circular value chain. The project’s systematic approach will be tested in three pilot regions, and the results will inform future replication across Europe. Waste streams will be chemically upcycled, creating virgin-equivalent feedstock for high-performance plastics, reducing waste, promoting sustainability, and advancing climate neutrality.
