Scania pioneers truck production by integrating remanufactured components, reducing material use and emissions for a more sustainable future.
By Robin Kumar Attri
In a groundbreaking achievement, Scania has become the world's first truck manufacturer to integrate the reused components directly into its main assembly line. This major milestone was achieved as part of the iReGear project, which aims to make truck production more sustainable. The project was carried out in collaboration with KTH Royal Institute of Technology and Scandinavian Transmission Service AB, and it was funded by Vinnova, Sweden's innovation agency.
The iReGear project, which ran from September 2023 to May 2024, focused on remanufacturing gearboxes. Unlike traditional methods that rely solely on new parts, this project reused old parts to create a gearbox that passed all the rigorous quality checks required for new components. The gearbox underwent the same tests as a new one, meeting over 100 quality and function parameters. The results confirmed that the remanufactured gearbox was "as good as new."
One of the most significant achievements of this project is its environmental impact. By reusing the parts, the remanufactured gearbox uses about 50% less material and produces 45% fewer carbon emissions compared to the gearboxes made entirely from new components. This demonstrates just how remanufacturing can reduce waste and also contribute to a more sustainable future for the automotive industry.
Remanufacturing, which involves using old parts to create new products, is gaining attention as a key strategy in achieving climate goals and supporting a circular economy. This process can help to reduce the shortage of resources and is also seen as a more sustainable approach to manufacturing. However, until now, remanufacturing in the automotive industry has mostly been limited to aftermarket parts. The success of the iReGear project paves the way for remanufactured components to be integrated into new vehicle production lines, marking a shift towards more sustainable manufacturing practices.
Fredrik Nilzén, Head of Sustainability at Scania, expressed his excitement about the project, stating, "This remanufactured gearbox is a great example of how we can make heavy vehicle production more sustainable and circular without sacrificing quality."
Assistant Professor Farazee Asif from KTH added, "This project shows that it’s possible to integrate remanufacturing into regular production. It’s a big step towards creating Circular Manufacturing Systems that use fewer resources and produce fewer emissions."
Ola Stålebo, CEO of Scandinavian Transmission Service AB, praised the collaboration, saying, "We’ve been remanufacturing gearboxes for over 50 years, but this project proves that remanufactured parts aren’t just for aftermarket use. This could become the standard for the future."
Scania’s achievement highlights the potential for the wider adoption of remanufacturing in the truck industry. By integrating reused parts into the main assembly line, this project demonstrates that sustainable practices can be adopted without compromising quality or performance. This approach could lead to more circular manufacturing systems, helping the automotive industry reduce its environmental impact while maintaining high standards of production.

Scania's success with the iReGear project marks an important step toward a more sustainable future for heavy vehicle manufacturing. By reusing components and reducing material usage and emissions, the company is leading the way in making truck production more environmentally friendly. This project could inspire the entire automotive industry to embrace similar practices, helping to create a cleaner, more sustainable transport sector.
