Panel member Ester van der Voet is teaching a new massive online open course called A Circular Economy of Metals: Towards a Sustainable Societal Metabolism. The course is now live and anyone interested in recycling of metals is welcome to join. The course explores options to move towards a more sustainable system of metals production and use. It will focus especially on the options to reach a circular economy for metals: keeping metals in use for a very long time, to avoid having to mine new ones. Details here.
