Abstract
We live in a dynamically changing world. There have been so many innovations in the last few years that raw materials have become really indispensable. The European Commission collected information in separate studies for Critical Raw Materials (CRMs) and for non-critical raw materials. This paper is based on that data. In 2011 there were 14 materials on the critical raw material list, but in 2017 this list had grown to contain 27 materials. Critical raw materials play a key role in technological innovation; they are the necessary raw materials for many innovations. In this paper, our aim is to identify groups using hierarchical cluster analysis and to identify which clusters are important for innovation. We selected three variables for cluster analysis: Economic Importance (EI), Supply Risk (SR), and End of Life recycling input rate (EoL), and we identified five homogenous groups. There is one group that seems particularly important because it includes only critical raw materials.
