Dow, Lear, and Jaguar Land Rover have co-developed a lightweight automotive seat cushion designed for end-of-life recyclability. The program reflects mounting pressure to cut lifecycle emissions and anticipate tighter circularity requirements, notably in Europe as discussions progress around the proposed End-of-Life Vehicles (ELV) regulation.
The cushion is based on Lear’s FlexAir concept, using Dow’s Infinair Polymers for Loop Technology. The approach forms a 3D loop structure from thermoplastic elastomer filaments via a melt-extrusion and water-cooling process, aiming to combine airflow, comfort and support while enabling a single-material system that is easier to recycle. Lear also developed trim-attachment methods intended to preserve this recyclability architecture.
Lear reports the solution could reduce seat assembly weight by up to 20 per cent and cut CO2e emissions by up to half, depending on lifecycle assumptions and end-of-life pathways. JLR plans to feature the cushions in its luxury vehicles.
Dow positions this context as a ‘systems’ challenge spanning the whole vehicle lifecycle, from material selection and component engineering to recycling infrastructure and end-of-life vehicle recovery.
From JLR’s perspective, the transition is broader than a single component: it’s a shift from linear to circular design, accelerated by public policy
