During this workshop, specific case studies focusing on the circularity aspect of materials research and innovation will be presented. In the framework of the Spanish presidency of the European Council, Spanish regional actors from the Basque Country such as Tekniker, Tecnalia, Azterlan, CIDETEC, CIC energiGUNE and Naturklima will be invited to showcase their activities and projects in this field. This will all be linked with the work that has been conducted by the AMI2030 initiative, anticipating the IM4EU partnership. The safe and sustainable by design approach will be also covered together with a presentation of the IRISS network. The session will conclude with a panel discussion on how to improve sustainability in materials research, followed by a networking lunch.
