Organizers of the 2020 Tokyo Olympics are hoping to source the gold, silver and bronze needed to make medals for the games from millions of discarded smartphones and other small consumer electronics.
Japan, one of the world's most gadget-obsessed nations, has 16 percent of the world's gold and 22 percent of the planet's silver currently sitting inside its consumer electronics.
By raising public awareness, the amount of electronic waste that is collected and recycled could be increased. Recycling is already widespread in Japan for many products, including milk cartons and plastic bottle caps. We need a system that makes it easy for consumers to turn in used consumer electronics.
