BASF Unveils New Polyamide Recycling Processes for End-of-Life Vehicles
- BASF's new recycling processes target polyamide 6 from end-of-life vehicles.
- Pilot projects with ZF and Pöppelmann involve components for Mercedes-Benz.
- Depolymerization and solvent-based methods reduce CO₂ emissions.
- Life cycle analysis confirms significant CO₂ savings compared to traditional methods.
Introduction of New Recycling Processes
BASF has developed two innovative recycling processes for polyamide 6 from end-of-life vehicles: depolymerization and solvent-based recycling. These methods aim to reduce the incineration of plastics and support the circular economy.
Pilot Projects and Collaborations
Pilot projects with ZF and Pöppelmann demonstrate the practical application of these technologies using components for Mercedes-Benz. The depolymerization process successfully recycled used oil pans into high-quality polyamide compounds.
Depolymerization Process
The depolymerization process breaks down polyamide chains into monomers, removing impurities and allowing for the production of high-quality recycled materials. This method ensures the recycled polyamide meets the highest standards for automotive applications.
Solvent-Based Recycling
The solvent-based recycling process targets automotive shredder residue, extracting polyamides in a pure form. This method was validated with a chain guide rail in series production at Mercedes-Benz, showcasing its effectiveness for difficult-to-recycle plastics.
Environmental Impact
Life cycle analyses confirm significant CO₂ savings with both recycling processes compared to traditional methods. These technologies contribute to the sustainable transformation of the plastics industry and align with upcoming regulatory requirements.
