As the mobility industry evolves toward decarbonization and resource efficiency, Röchling Automotive is at the forefront of developing advanced polymer solutions that combine technical performance with circular responsibility.
In collaboration with Aquafil, the company has validated ECONYL® regenerated nylon for use in air filter housings — a demanding application that requires mechanical strength and thermal stability. This partnership represents a concrete step toward integrating regenerated materials into high-performance automotive components.
Moving Sustainability forward in the Automotive Sector
For Röchling Automotive, circular innovation is more than a corporate objective — it is a strategic driver of innovation.
“By embracing circularity, we increase the share of responsible materials in our products, reduce their life-cycle impact, and lower the carbon footprint of our components. This also supports our Scope 3 decarbonization targets and strengthens our commitment to a more sustainable supply chain,” the company explains.
By embedding circular principles into its design and material strategy, Röchling Automotive demonstrates that responsibility and performance can coexist in modern engineering.
A Partnership Built on Shared Vision
The collaboration between Röchling Automotive and Aquafil began with a shared commitment to finding responsible solutions for high-performance applications. Over nearly two years of research, testing, and validation, both teams worked closely to ensure that ECONYL® regenerated nylon met Röchling’s strict performance requirements.
“Our collaboration with Aquafil reflects our shared commitment to more conscious solutions for demanding applications like air filter housings,” notes Röchling Automotive. “The ECONYL® nylon proved its strong technical performance and responsibility, opening the door for future use in air filter boxes and other components.”
Developing a thermally stabilized compound capable of meeting these specifications was one of the project’s key technical challenges — and a major achievement.
“This collaboration showcased true efficiency and synergy. With clear performance targets and Aquafil’s reliable delivery, validation ran smoothly. Developing a thermally stabilized grade that met our specifications was a real achievement. It showed that shared vision and strong communication make even complex goals achievable.”
The process highlighted how open communication and technical partnership can transform challenges into tangible innovation opportunities.
Delivering Performance and Accelerating Circularity
Testing confirmed that the ECONYL®-based compounds met the required mechanical and thermal performance targets.
“The grades we tested aligned perfectly with the performance targets we share with Aquafil, confirming their suitability as a true alternative to petroleum-based materials. ECONYL®-based compounds not only meet all technical requirements but also combine strong performance with greater material efficiency and reduced reliance on virgin resources,” explains Röchling Automotive.
By aligning technical performance and circular design, Röchling Automotive demonstrated that regenerated materials can serve as reliable alternatives to conventional, petroleum-based plastics, providing durability, dimensional stability, and heat resistance while contributing to a more resource-efficient production process.
“Using circular materials in injection molding presents challenges but also great opportunities for innovation,” the company adds. “This approach drives a more circular and responsible value chain. By leveraging ECONYL® nylon, we can accelerate the use of regenerated materials with our OEMs and promote more conscious material choices in component development.”
In addition to its technical reliability, ECONYL® regenerated nylon supports compliance with the EU End-of-Life Vehicle (ELV) Directive, which encourages the reduction of virgin materials and the increase of regenerated content in vehicle manufacturing.
“ECONYL® regenerated nylon helps OEMs meet ELV requirements by reducing virgin material use and increasing regenerated content. Made 100% from waste, it supports circularity while maintaining high performance and compliance with regulations.”
Looking Toward the Future of Automotive Circularity
The collaboration between Röchling Automotive and Aquafil illustrates how innovation, performance, and responsibility can advance together.
After nearly two years of development and validation, the project has opened the door for the future use of ECONYL® regenerated nylon in air filter boxes and other components, reinforcing the role of circular materials in the evolution of the mobility industry.
By continuing to explore regenerated solutions, Röchling Automotive demonstrates that technical excellence and conscious design can work hand in hand to drive meaningful progress in automotive manufacturing.
