Mining

MIT engineers have developed a new low-temperature process for extracting battery-grade lithium from hard rock, while also reducing waste, reports Gayoung Lee for Gizmodo. “Mining is essential to technology and therefore to society, yet it is perceived negatively by much of the public as a destructive, polluting industry, in some cases with good reason,” explains Prof. Yet-Ming Chiang. “We hope to help change that perception by showing that there are cleaner, more sustainable ways to do it.”

MIT Environmental Solutions Initiative Program Scientist Scott Odell speaks with USA Today reporter Kate Petersen about the impact of renewable energy mining. “We can really reduce the amount of virgin metal we need to mine just by using the old metal we've already got,” says Odell. “We need to design our systems such that we have the capacity to recycle those metals.”
