For a circular energy transition
Exponential demand for critical materials, driven by the energy transition, may trigger supply chain problems. Circular economy business models could help decouple the renewable energy sector from material consumption. However, facing major economic, regulatory and financial barriers, the transition of the sector towards a circular economy still has a long way to go. In our report for the Green Purposes Company, we propose an action plan for the renewable energy sector to be fully aligned with the principles of a circular economy and reap its benefits.
