Current mining methods are slow, energy-intensive and highly damaging to the environment. They generate acidic and radioactive waste, and they leach toxic chemicals into the ground. “We have to figure out ways to do it better and cleaner,” says Justin Wilson, a chemistry professor at the University of California, Santa Barbara. He and his colleagues recently tested a new way to extract rare earth elements from recycled electronic waste. “I’m optimistic that we can collectively find solutions to these problems as long as the federal government remains committed to providing funding for this research,” Wilson notes.
