EAB Wins Catena’s Reuse Challenge with Groundbreaking Steel Solution
How far can reuse be taken in modern new-build construction? In Catena’s project in Linköping, EAB demonstrates that the possibilities are greater than many might think. By reusing load-bearing steel structures, both climate impact and resource consumption have been significantly reduced – while at the same time opening up new pathways for the development of the construction industry.
In Catena’s new-build projects, a competition element has been introduced – the Reuse Challenge – encouraging contractors to develop and implement the most ambitious reuse solutions possible. Entries are assessed from a holistic perspective, taking into account factors such as carbon savings, volume, functionality, creativity, and cost-effectiveness. EAB has been named the winner of the Reuse Challenge for its solution involving reused load-bearing steel structures in the logistics facility completed for San Sac in Linköping in 2026.
Reuse was an integral part of the project from the outset. The result demonstrates how circular solutions can be put into practice – even in structural components that traditionally place very high demands on material quality and performance. By reusing eight steel sections from the construction of Karlatornet in Gothenburg, EAB created five new load-bearing columns for the property.
Reusing load-bearing structural elements is uncommon and technically demanding due to the stringent safety requirements involved. The solution was made possible through collaboration with partners who assess and certify reclaimed materials before they are reintroduced to the market.
