Leading the Charge in Sustainable Automotive Design
The automotive industry is at a crossroads, balancing the demands for sustainability with the need for advanced performance. In The Netherlands, this balance is being managed through innovative design and the use of new materials. In a conversation with Freek de Bruijn, Program Manager Design and Materials at RAI Automotive Industry NL, he says, “Our goal is to emit as little CO2 as possible by 2030,” highlighting the ambitious targets set by the industry. This commitment to reducing emissions is driving a focus on zero-emission vehicles, hydrogen-powered technologies, and smart innovations, all of which contribute to a greener future.
However, little has been done in terms of policies for materials. “We do have the national circular economy program,” says de Bruijn, “and there is a little bit mentioned about lightweight and what that means for the automotive industry and mobility, in general. But we don’t have a clear policy document for materials like we have with batteries or hydrogen.” Such a limitation means that a lot of companies, including RAI members, are looking for innovation possibilities and subsidies to stimulate their innovation with materials.
Towards a Circular Economy
The traditional “take-make-dispose” economic model is undergoing a transformation. In The Netherlands, the government is pushing for a complete transition to a circular economy by 2050. This innovative approach aims to keep resources in use for longer by prioritizing reuse and remanufacturing over waste. “Imagine a system where what we currently discard becomes the fuel for new products,” says De Bruijn. “That’s the essence of the circular economy. By repairing, refurbishing, and recycling existing materials, we can significantly reduce our dependence on virgin raw materials extracted from the earth.” This vision is reflected in the National Circular Economy Programme (NCPE), which outlines a roadmap for achieving a dramatic reduction in virgin material use. The ambitious goal is to slash virgin material consumption by 50% by 2030, paving the way for a complete phase-out by 2050.
This theme is already in play and is, therefore, new to the automotive industry and supply chain in The Netherlands. Most SMEs are struggling to keep up, making it a serious challenge. Therefore, design must be optimized, minimizing resistances to meet circularity targets. The circular economy offers a win-win solution. By conserving resources, we lessen our environmental impact. Additionally, it fosters innovation in product design and waste management, creating new economic opportunities.
RAI Automotive Industry NL supports the Circular Economy R-ladder methodology, which emphasizes minimizing raw material use through a hierarchical approach. The R-ladder demonstrates the degree of circularity: The higher up the R-ladder strategy is, the more circular it is, and the lower the raw material used is. The R-ladder consists of six steps representing different circularity strategies:
R1 - Refuse and rethink: Abandon products or use them more intensively
R2 - Reduce: Manufacture efficiently or optimize usage
R3 - Re-use: Utilize second-hand products
R4 - Repair, refurbish, remanufacture, repurpose: Repair or reuse parts
R5 - Recycle: Process and reuse materials
R6 - Recover: Recover energy from materials
RAI Automotive Industry NL is committed to working through this methodology in cooperation with its members. By adopting the R-ladder approach, the industry aims to significantly reduce waste and enhance the sustainability of automotive materials, ensuring that resources are used as efficiently as possible throughout the product life cycle. This commitment not only supports environmental goals but also aligns with broader efforts to create a sustainable and resilient automotive sector.

Despite the significant advancements, the Dutch automotive industry faces unique challenges in adopting sustainable materials. “Raw materials are scarce, and it takes a lot of energy to extract them,” De Bruijn highlights. This scarcity underscores the importance of recycling and reusing materials to mitigate environmental impact and reduce dependency on finite resources. For example, prices for copper are reaching all-time records almost daily, and if the way copper is harvested is not changed, known reserves could run out in as little as 37 years. Research is being conducted on replacing copper with silver and carbon in PCBs to address this issue.
Projects focused on retracting materials from existing vehicles and PCBs are crucial in addressing this challenge, aiming to create a circular economy where materials are continuously repurposed. There are research projects using AI to identify every part of a depreciated vehicle: what materials are present, their locations, and the types of metals involved. This AI system also assesses the degree of recyclability for each metal and provides feedback on how to efficiently disassemble components, suggesting improvements like using snap fits instead of screws. Currently, there are many different rare metals in PCBs. Existing recycling methods are not designed to recover these substances effectively, leading to losses. The solution lies in scanning and designing methods to locate and extract these metals. Research shows that AI, combined with cobots, can identify and remove these materials from printed boards, a step towards developing a passport for PCBs similar to battery passports.
One of the critical strategies being explored is remanufacturing, which involves dismantling and rebuilding engines and other components to extend their lifespan and reduce waste. “Remanufacturing allows us to rebuild certain parts from scratch, minimizing the need for new raw materials,” De Bruijn explains. However, this process is still in its experimental phase and not yet profitable, posing a challenge for widespread adoption. The industry is working to refine these techniques to make them more economically viable and scalable.
Another challenge is the integration of lightweight materials such as carbon fiber and composites, which are essential for reducing vehicle weight and improving efficiency. While these materials offer significant performance benefits, their production and recycling processes can be complex and costly. The industry is investing in research to develop more efficient manufacturing techniques and recycling methods for these advanced materials.
In addition to technological advancements, regulatory frameworks must evolve to support the adoption of sustainable materials. “Legislation and regulation need to catch up with technological developments,” De Bruijn asserts.
