The Olympics have ancient roots, but Tokyo is finding ways to update the event in time for the summer games in 2020. The latest idea shared by the organizing committee may not be as flashy as an artificial meteor shower or as essential as modernized toilets, but it's no less innovative. As Engadget reports, all of the medals awarded at the 2020 Summer Olympics will be made from recycled electronics—and their designs have been unveiled to the public for the first time.

Many electronics contain precious metals like copper, silver, and gold—the same elements needed to make the Olympic medals. With hundreds of pounds of the materials destined to become e-waste in Japan each year, the Olympic committee came up with a plan to put some of it to good use.

In 2017, the Olympics organizers called upon Japanese residents to donate their old smartphones and other devices so they could be made into medals for the 2020 games. Over the past two years, the committee has collected 78,985 tons of donated electronics (including more than 6.2 million phones), and from that haul they've recovered approximately 70 pounds of gold, 7716 pounds of silver, and 4850 pounds of bronze, which was more than enough material to cast new medals for each Olympic event. You can get a peek at the design of the final products in the video below.

The 2020 Olympics will mark Tokyo's second time hosting the games (their first go was in 1964). By the time the games conclude next summer, organizers are expected to have spent $20 billion putting the event together.
