Between 2010 and 2015, the U.N. think tank United Nations University tracked 12 Asian countries to see how much electronic waste they produced. On average, the volume of digital trash increased by nearly two thirds over this period, with certain countries worse than others. China, for example, doubled its e-waste. By the time 2015 rolled around, the region produced 22 pounds of e-waste per person per year. The worst culprit was Hong Kong, which trashed nearly 48 pounds per person, while more frugal Cambodians dumped fewer than 3 pounds per person.
