Exploring Phyto Mining with Plants for Nickel Extraction
Scientists are exploring phyto mining, a method that uses plants to extract metals from soils. Hyper accumulators, plants that absorb high amounts of metals, are being investigated for their potential in extracting nickel. The US government is providing funding to explore using plants to extract nickel from American soils to increase the domestic supply. This method could reduce the need for traditional mining and imports while supporting the renewable energy transition.
Environmental and Economic Impact of Phyto Mining
Phyto mining has the potential to reduce greenhouse gas emissions compared to traditional mining methods. Hyperaccumulators can clean up contaminated soils and provide a sustainable source of nickel for batteries. Researchers are working to find hyperaccumulating plants that can efficiently extract metals, like nickel, from specific soils. The long-term goal is to improve soils and ecosystems through phyto mining while meeting the increasing demand for battery materials.
Some species can absorb extreme amounts of nickel from soils. Such “phytomining” could help provide batteries essential for the renewable revolution. Thanks for listening to WIRED. Talk to you next time for more stories from WIRED.com and read this story here.
