Large-Scale Reuse as EcoDataCenter Builds the Data Centres of the Future

At the Kvarnsveden industrial site in Borlänge, one of Sweden’s largest reuse projects is taking shape. WSP has carried out an extensive feasibility study of the dismantling of the PM12 industrial building. This study supports EcoDataCenter in managing material flows together with local stakeholders to enable more sustainable construction.

Reuse coordination – The key to circular building

EcoDataCenter is developing a new mega campus for data centres in Borlänge. To enable this expansion, the former paper machine hall PM12 – a building of approximately 45,000 m² (485,000 ft²) including office spaces – is being dismantled. EcoDataCenter’s ambition is clear: as much of the building as possible should be reused and given new life in other locations, preferably nearby. 

WSP has produced a comprehensive feasibility study including climate calculations and an implementation plan for the continued handling of materials from PM12. Through site inventory, BIM modelling and climate assessments, thousands of building components have been analysed to evaluate condition, dismantling potential and climate impact.  

Structured divestment processes

EcoDataCenter plans its reuse in two phases: during the first quarter of 2026, fixtures and non-load-bearing structures will be dismantled. This will be followed by load-bearing elements and larger building sections in 2027. 

To maximise climate benefits, it is crucial to connect identified reusable products with potential buyers. Through a structured divestment process, the project ensures that as much material as possible finds a new purpose and that climate benefits are maximised. 

WSP actively shares knowledge and experience on strategy, procurement and logistics with EcoDataCenter, whose goal is to reduce climate impact, waste and costs through circular material flows. 

This project shows that large-scale reuse is not only possible – it is a key to the future of construction. Through data-driven analysis and close collaboration with EcoDataCenter, we contribute to solutions that make a real difference for the climate

The plan: first phases completed by 2027

With access to renewable energy, EcoDataCenter is transforming the former paper mill at Kvarnsveden into a state-of-the-art facility for next-generation data centres. The site in Borlänge is now becoming one of the region’s largest construction projects, with plans for the first phases to be completed as early as 2027. Through smart resource use and sustainable building processes, EcoDataCenter demonstrates how to maximise resource efficiency and reduce the climate footprint. 

EcoDataCenter is transforming the former paper mill at Kvarnsveden into a state-of-the-art facility for next-generation data centres. Projects of this scale offer valuable lessons for increasing reuse within the construction and civil engineering industry
