Anyone with a cell phone in their pocket may be carrying around a bit of Olympic history—or Olympic future, that is. That’s because the organizers of the 2020 Tokyo Olympics and Paralympics recently announced that they will make the gold, silver and bronze medals awarded at the game from materials recovered from electronics donated by the public, reports Andrew McKirdy at The Japan Times. Starting in April, the Olympic committee is asking consumers to drop off their old electronic devices in collection boxes placed in more than 2,400 NTT Docomo telecom stores around the island nation and "an undecided number of public offices throughout the country," according to a press release. As Elaine Lies at Reuters reports, the committee hopes to recover eight tons of gold, silver and copper from millions of cell phones and other recycled devices. After processing that should yield about two tons of purified metal, enough to manufacture the 5,000 medals needed to award athletes of the Olympics and Paralympics. “There's quite a limit on the resources of our earth, and so recycling these things and giving them a new use will make us all think about the environment,” Sports Director of Tokyo 2020 Koji Murofushi, 2004 Athens Olympics hammer-throw gold medalist told a news conference, reports Lies. "Having a project that allows all the people of Japan to take part in creating the medals that will be hung around athletes' necks is really good."
