"Eggshell Waste: A New Source for Rare Earth Element Recovery in Green Energy"
Originally Published 1 year ago — by Phys.org
Researchers from Trinity College Dublin and iCRAG have discovered that eggshell waste can be used to recover rare earth elements (REEs) from water, offering an eco-friendly and low-cost method for extracting these critical materials needed for green energy technologies. The study, published in ACS Omega, highlights how calcium carbonate in eggshells can absorb and separate REEs, potentially transforming waste into a valuable resource and supporting sustainable practices.
