Most batteries used in technology like smartwatches and electric cars are made with lithium that travels across the world before even getting to manufacturers. But what if nearly half of the lithium used in the U.S. could come from Pennsylvania wastewater?
A new analysis using compliance data from the Pennsylvania Department of Environmental Protection suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country's demand.
Already, researchers in the lab can extract lithium from water with more than 90% efficiency according to Justin Mackey, a researcher at the National Energy Technology Laboratory, and his Ph.D. advisor Daniel Bain, associate professor of geology and environmental sciences at the University of Pittsburgh's Kenneth P. Dietrich School of Arts and Sciences.
