Chinese researchers have identified a fern species capable of accumulating rare earth elements (REEs) through a natural process called biomineralization, according to a groundbreaking study published in Environmental Science & Technology. The discovery reveals how the plant forms "self-assembled" mineral phases within its tissues, offering new insights into sustainable extraction methods for these critical resources.
REEs, essential for renewable energy technologies, electronics, and defense systems, face supply chain vulnerabilities due to geopolitical tensions and environmentally damaging mining practices. This research highlights a potential eco-friendly alternative by harnessing plant-based mechanisms to recover REEs from soil or industrial waste.
Scientists emphasized the dual significance of the findings: advancing biotechnological solutions for resource scarcity while reducing ecological footprints. The study aligns with global efforts to transition toward greener energy systems, positioning the Chinese mainland as a key player in innovative mineral recovery research.
