From the Sector

Adient, Jaguar Land Rover, and Dow have worked together to produce seat foam for the luxury car manufacturer’s vehicles using closed-loop recycled components. This represents an industry-first in the automotive sector, heading towards a circular economy and a lower CO₂ footprint for cars as the end product.

In order to address the environmental impact of polyurethane (PU) foams used in car seats, the industry partners decided to team up. This means so-called ‘post-consumer’ PU molded foams have previously been collected from end-of-life vehicles, sorted, and shredded. On this basis, Dow produces a new, circular polyol, which is subsequently processed and integrated into Adient’s seating formulas. As a result, the Adient Front Seat Cushion prototypes are currently composed of 20% re-polyol from PU end-of-life vehicles.

This is the first time, to the awareness of all parties involved, that a PU molded foam for seating applications has been produced under these conditions. This milestone represents a significant leap forward for the automotive industry, positioning PU at the heart of a circular economy system. By integrating recycled components into luxury vehicle seat foams, the partners are not only reducing the environmental impact but also paving the way for a more sustainable future in automotive manufacturing.

“Developing components with closed-loop recycled foams represents a major milestone for the team and simultaneously spurs us on to continuously increase the proportion of recycled materials in our seating systems in the future,” said Frank Toenniges, Director Sustainable Product Design & Business Process Improvements at Adient. “Additionally, it positions the actors along the value chain favorably to comply with the proposed European End-of-Life Directive.”

Andrea Debbane, Chief Sustainability Officer at JLR stated: “This breakthrough is a great example of how the automotive value chain can work as a collective to demonstrate that full circularity is feasible and unlock meaningful change at scale. This way of working holds significant potential for increasing sustainability and is critical to JLR's transition to more circular vehicles.”

As a next step, further research will be conducted to increase the percentage of re-polyol content. At the same time, the closed-loop seat foam will be tested with JLR on a production scale from early 2025.

Adient, a leading global supplier of automotive seating systems, has won the "German Innovation Award 2022" in the category "Information Technologies and Functional Software". Adient's concept of "Mixed Reality as a key to efficient induction training", developed as a pilot project by employees at Adient’s Saarlouis production site, was able to convince the interdisciplinary jury of experts from science and technology.

Adient's concept aims to efficiently train new employees in production areas with the aid of mixed reality glasses. These glasses can be used to scan QR codes that are attached to each workstation. The QR codes call up corresponding videos in the field of view of the glasses which visually help the user to learn about the processes at the respective workstation, thus replacing the previous paper-based work instructions.

With this concept, Adient is using the technology to design and develop world-class seating solution for its global customers. New employees can thus be given a comprehensive understanding of the complex structures of a car seat much better, faster, and in a more realistic way. In addition to optimized communication, changes in the process such as product modifications can be implemented more easily than with printed work instructions.
