The RTI Summit 2025 was entitled “A Research and Technology Infrastructures Ecosystem for Breakthrough Science and Innovation” and included six topical sessions to identify (i) priorities, (ii) opportunities, and (iii) measures to track the impact of RTIs. Andreas Falk (BNN), representing the funded projects ATIMA and InnoMatSyn, chaired the sessions and panel discussion on “Materials Circularity and Critical Raw Materials”. The findings of the sessions will build the basis for future iterations on the 10th framework program and shall feed into discussions along future funding initiatives on regional, national and European level. These valuable insights will also feed into the further development of the ATIMA roadmap.
