The specific objectives of the study are: (1) identification and analysis of the global availability, geographical spread and prices of critical metals and possible increasing pressure on the supply due to a growing demand through the rising uptake of certain innovative technologies; (2) prioritization of critical metals regarding growing demand and possible scarcities and analysis of recycling potential for the identified critical metals with high prioritization; (3) identification of framework conditions that could help to foster technologies that enable the implementation of closed-loop recycling systems for critical metals.
