Researchers are turning to nature for a cleaner way to recover rare earth elements hidden in industrial waste. According to a recent report, coal ash, red mud, and mine tailings hold significant amounts of these valuable minerals, which are essential for modern technologies.
The proposed approach draws inspiration from organisms such as diatoms, sea sponges, and plants. These organisms naturally interact with minerals in their environments, and scientists believe their mechanisms could be adapted to extract rare earths from waste more sustainably than conventional methods.
If successful, the technique could turn enormous waste piles into a practical source of materials. The report highlights the potential to address both waste management and supply concerns, though it notes the work is still in an exploratory phase.
