Scientists have developed a safe and eco-friendly method to extract gold from old phones, laptops, and other electronic waste. Published in Nature Sustainability, the process uses a three-step technique involving a common disinfectant, a special polymer, and heat to recover high-purity gold without toxic chemicals. With e-waste reaching record levels and only a fraction of valuable materials being recycled, this breakthrough offers a cleaner, scalable solution to recover lost resources and promote sustainable recycling.
