Cover Story: A novel, energy-efficient method to recover copper and carbon from discarded electrical cables is presented. Highlighting copper as a valuable "urban mineral", this study utilizes microwaves to rapidly separate high-quality copper and carbon in just 30 seconds. This approach cuts energy use by 80% as compared to traditional incineration methods, offering a low-cost, scalable, and eco-friendly solution for managing cable e-waste. View this paper
