Researchers at the University of Newcastle have pioneered an acid-free method to reclaim nearly all silver from decommissioned solar modules. Using mechanical crushing and froth flotation, this efficient technique takes just three minutes to extract high-grade metal for reuse. This breakthrough supports a circular economy while reducing chemical waste in the renewable energy sector.
