“…From a theoretical perspective, adding to the prior research [4,28,36], this study adapts the criticality assessment matrix provided by the EU and integrates it with EIO modelling. This novelty creates an extra evaluation perspective and helps to deliver more robust results by considering environmental impacts next to supply risks and economic importance (van den [32,36,37]). Therefore, the scientific contribution Total GVA weighted 119990.78 Sources: [12,15] of this research is proposing a numerical evaluation method for critical raw material supply chains.…”

“…There is little predictive decision-making basis that can support policymakers to mitigate niobium criticality. Whereas the literature provides certain knowledge on raw material supply chain analysis [4,7,28,32,36,37], a research gap exists in numerical evaluations of CE solutions in a CRM supply chain combining EU's criticality assessment matrix under future scenarios. There is a great demand for a tailored method that facilitates supply chain design and evaluation by integrating the elements of both criticality and circularity.…”

Critical Raw Materials attract increasing attention due to their depleting reserves and low recyclability. Niobium, one of the most rare and vital elements, is primarily found in Brazil. This research explores the potential impact of Circular Economy (CE) strategies on mitigating niobium's criticality within Europe. First, a niobium supply chain is designed and analysed by Enterprise Input–Output modelling. Second, the supply risk is calculated based on the criticality matrix proposed by the European Commission under three scenarios associated with resources, technologies, and policies. The results show that urban mining is a potential solution to reduce niobium’s criticality and mitigate its environmental impacts. A higher recycling input rate and/or a mix of recycling and substitution strategies is necessary to offset niobium’s criticality. Aligned with the CE action plan, the research offers a scientific foundation to strategically prevent the risk of niobium supply shortages.
