UK researchers develop greener, more sustainable ways to recover metals from electronic waste

As electronic waste (e-waste) piles up globally, researchers at the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment and the Stanley and Karen Pigman College of Engineering are spearheading innovative methods to recover valuable metals from discarded devices and industrial waste.

E-waste — including smartphones, laptops and spent batteries — contains critical materials such as lithium, cobalt and nickel essential for electrochemical energy storage applications. However, traditional recycling methods often rely on harsh chemicals and energy-intensive processes, creating environmental and economic challenges.

Now, researchers are developing innovative solutions to make obtaining these metals safer, more efficient and sustainable.
