Abstract
An increasing global demand for new products and emerging technologies that use rare earth elements (REEs) while global consumption of rare earth elements (REEs) has registered a steady and significant increase, their supply has drastically diminished. Rare earth elements (REEs) are found in most everyday applications because of their unique chemical and physical properties. The distribution and supply of the rare earths are highly demand, so convergence technologies are necessary for the recovery of critical rare earth elements from coal power plants waste or coal combustion by products and simultaneous CO2 utilization. Recycling and Utilization of coal byproducts are the sustainable solutions to climate change. Carbonation is one of the cost effective and eco-friendly processes for the recovery of rare earth metals by using limestone and limestone mixture from power plants waste or sludge. This accelerated carbonation is more suitable process for CO2 capture and utilized this CO2 for manufacturing different kinds of new calcium carbonates used industrial residues (e.g., power plants ash). This paper mainly concerns the case studies of sustainable critical rare earth elements in various fields and managing the supply chain risks of rare earth elements (REEs).
