Electronic waste, or e-waste, is the fastest-growing segment of the municipal waste stream. Nearly 100% is recyclable, and valuable materials like plastics, metals, and glass can be recovered. E-waste also can contain toxic materials, like lead, mercury, and arsenic. Worldwide, up to 50 million tons of e-waste is expected to be dumped in 2017. Yet, in the United States, less than 30 percent is recycled. It’s no surprise that 25 states—and the District of Columbia—have electronics recycling laws.
