Abstract:
An increasing global demand for new products and emerging technologies that use rare earth elements (REEs)have drastically diminished their supply, while global consumption of rare earth elements (REEs)has registered a steady and significant increase. Rare earth elements (REEs) are found in most everyday applications because of their unique chemical and physical properties. So, convergence technology is necessary for the recovery of critical rare elements from power plants waste for simultaneous CO2 utilization. Carbonation is one of the cost effective and ecofriendly process for the recovery of rare earth metals by using limestone and limestone mixture from power plants waste or sludge. This accelerated carbonation is a more suitable process for CO2 capture and can utilize this CO2 for manufacturing different kinds of new calcium carbonates used industrial residues (e.g., power plants ash). This paper mainly focused on the case studies of sustainable critical rare earth elements in various fields and managing the supply chain risks of rare earth elements (REEs).
