PLA is a promising alternative to PET in technical textiles but it’s far too valuable to simply let it biodegrade. In a collaborative research project, Stoffschmiede, known for its material-driven innovation, joins forces with the Institut für Textiltechnik (ITA) of RWTH Aachen, Institut für Anorganische Chemie (IAC) and a strong network of academic and industry partners to explore how advanced recycling can unlock the full circular potential of PLA. Together, the team develops chemical and thermo-mechanical recycling processes that turn both virgin and recycled PLA into durable multifilament yarns and high-performance fabrics. These are tested in real-world applications. To objectively assess the environmental and economic impact, the project applies Life Cycle Assessment (LCA) and Techno-Economic Analysis (TEA).
