E-waste: Dark Side of Digital Age What happens to those old computers once they’ve been abandoned for newer models? / The refuse from discarded electronics, also known as e-waste, / often ends up in landfills instead of being recycled. / And that means toxic substances like lead and mercury that are commonly used in these products / can contaminate the land, water and air. / The United States generates more e-waste than any other nation. / Some of that waste is recycled. / For example, steel, aluminum and copper are often stripped from outdated machines and reused in newer models. / But even recycled parts come at a price. / An estimated 50 to 80 percent of e-waste collected in the United States for recycling / is exported to areas such as China or India or Pakistan, / where workers taking apart the old machines are handling toxic chemicals / that can pose serious health problems. / Luckily, some manufacturers are beginning to assume greater responsibility / for what happens to their products after they become out-of-date.
