Summary:
As more and more electric cars are traveling on the roads of Europe, this is leading to an increase in the use of the critical metals required for components such as electric motors and electronics. With the current raw material production levels there will not be enough of these metals in future -- not even if recycling increases.
As more and more electric cars are travelling on the roads of Europe, this is leading to an increase in the use of the critical metals required for components such as electric motors and electronics. With the current raw material production levels there will not be enough of these metals in future -- not even if recycling increases. This is revealed by the findings of a major survey led by Chalmers University of Technology, Sweden, on behalf of the European Commission.
Electrification and digitalisation are leading to a steady increase in the need for critical metals in the EU's vehicle fleet. Moreover, only a small proportion of the metals are currently recycled from end-of-life vehicles. The metals that are highly sought after, such as dysprosium, neodymium, manganese and niobium, are of great economic importance to the EU, while their supply is limited and it takes time to scale up raw material production. Our increasing dependence on them is therefore problematic for several reasons.
"The EU is heavily dependent on imports of these metals because extraction is concentrated in a few countries such as China, South Africa and Brazil. The lack of availability is both an economic and an environmental problem for the EU, and risks delaying the transition to electric cars and environmentally sustainable technologies. In addition, since many of these metals are scarce, we also risk making access to them difficult for future generations if we are unable to use what is already in circulation," says Maria Ljunggren, Associate Professor in Sustainable Materials Management at Chalmers University of Technology.
