Coal combustion byproducts recycling and utilization for sustainable solutions to climate change
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).
