Overview

• The study was conducted by Trinity College Dublin's School of Natural Sciences and iCRAG.
• Eggshells were tested in solutions containing rare earth elements at temperatures ranging from 25°C to 205°C.
• At higher temperatures, the eggshells transformed, forming new minerals like kozoite and bastnasite.
• This method aligns with circular economy principles and addresses environmental concerns of traditional extraction methods.
• Findings published in the journal ACS Omega highlight the potential for waste valorization in green technologies.
