The consumer electronics we use everyday often don’t degrade well. A landfill is a terrible place for old smartphones, televisions, or computers. Electronic waste can be composed of heavy metals, rare earth metals, and other potentially hazardous material. Much of it is hard to recycle, and disposing of e-waste is costly and dangerous. So, for decades, Europe and the United States have shipped e-waste to Africa and Asia, sometimes illegally. In a new twist on an old problem, Europe is starting to hide some of those electronics inside used cars.
