Gradiant, a water recycling enterprise, announced on the 20th of this month that it would build a commercial lithium production facility in Monroe, Susquehanna County, within the Marcellus Shale region of Pennsylvania. The facility, fully operated by its subsidiary alkaLi, adopts the world's first integrated "extraction-concentration-conversion" (EC²) technology to directly extract lithium from produced water in oilfields. It has achieved a 97% recovery rate and a 99.5% purity of battery-grade lithium carbonate. The company has signed multi-year offtake agreements and, upon commissioning in early 2026, will be able to supply 5,000 mt of battery-grade lithium carbonate annually to US lithium battery manufacturers.
