Our cities are becoming the mines of the future. Urban mining is changing the way we think about waste. Phones, computers, batteries, cables, and old appliances contain valuable materials such as copper, lithium, cobalt, and rare earth elements. For decades, we have searched for these resources beneath the surface of the Earth. Now, we are beginning to recognize that many of these materials already exist in the products surrounding us. This shift in perspective is powerful. A discarded device is no longer just waste. It is a source of materials, energy, and opportunity waiting to be recovered. The cities of the future may not only consume resources. They may become one of our greatest sources of them.
