Vanadium is critical for Europe’s green transition and strategic autonomy. It is not yet produced in significant volumes in the region, without a reliance on non-European feedstock. Instead of mining for resources, we at Novana recycle industrial side streams into high purity vanadium in Pori, Finland, close to our Nordic supply chain.
As a transition mineral, vanadium enables the creation of two main compounds: Stabilized slag material (SSM) is produced as a byproduct of the recovery process and used as a green cement replacement material. Despite being categorized as a critical mineral by the EU, vanadium is currently not being primarily produced in the region.
Recovering vanadium through circular methods answers to raw material sustainability issues, while supplying a vital mineral for greener steel, alloys and batteries. Our unique closed-loop process ensures that no materials are wasted and that more carbon is captured in the process than released.
Creating a world where nothing is wasted. Where vanadium is recovered without mining, through circular technology. Vanadium is critical for Europe’s green transition and strategic autonomy. It is not yet produced in significant volumes in the region, without a reliance on non-European feedstock.
