Role: After briefly recalling what criticality is, which raw materials have been identified as critical for the EU presently and what could be the evolution up to 2035 , this flowSheet brings information from different sources - among which the Critical Raw Materials Innovation Network (CRM_InnoNet) - on what substitution is, and the strategies to implement. Then, different data platforms able to answer the question ‘where to find the substitution material?’ in the EU, or in the World, are presented. Finally, two methodologies related to the prediction of new resources (respectively spatial and quantitative) are explained.
