Cover Story: Biosurfactants offer a sustainable alternative to conventional acid-based methods for recovering critical minerals from electronic waste, spent batteries, and mining residues. The performance of rhamnolipids, sophorolipids, and surfactin in metal binding and micelle formation are examined, yielding recovery efficiencies exceeding 75% for copper, zinc, and lead under optimized conditions. A Green Chemistry Metrics Framework is developed to quantify process benefits, demonstrating an up to 65% reduction in waste generation and an up to 55% lower carbon footprint compared to acid leaching. Key challenges related to biosurfactant recyclability, standardization, and mineral selectivity are discussed, and innovative strategies are proposed for scale-up and integration with complementary extraction technologies.
