In what it claims to be a ‘world first’ for a heavy vehicle manufacturer, Scania is aiming to cut emissions by utilising remanufactured parts on its main assembly line in Sweden. ​

The iReGear research project saw a new gearbox built on the production line using remanufactured parts. The test saw 50% less new parts used and a 45% reduction in carbon emissions produced, compared to building a brand-new unit.

Fredrik Nilzén, Head of Sustainability at Scania, said: “This remanufactured gearbox is a compelling example of how the manufacturing of heavy vehicles can become more sustainable, circular and efficient, while still retaining the highest quality standards.”

The ‘remanufactured’ gearbox is subjected to the same rigorous testing, to make sure they meet the quality and performance standards of new parts. The production process showcases several environmental advantages, while replacement rates during gearbox remanufacturing can vary between 10% to 100%, depending on the wear of the donor gearbox.

Using old parts to create new products is considered a promising strategy for OEMs to achieve their climate goals and transition towards a circular economy. In spite of its potential, remanufacturing in the European automotive sector is mainly confined to the aftermarket, which accounts for only 1.1% of new manufacturing according to a report by the European Remanufacturing Network (2015).

Wider adoption of this process requires vehicle manufacturers to integrate the remanufactured components directly into the production lines of new vehicles, rather than selling them separately as a spare part. It is hoped that the pioneering iReGear project will help lead the way for the industry to make this necessary shift in the efforts to create a more sustainable and cleaner transport industry.
