The Olympics will be held in Tokyo, Japan in 2021, and they unveiled their Olympic medals

that are made from recycled mobile phones. The Tokyo Organizing Committee of the Paralympic and Olympic Games stated that their Medal Project for Tokyo 2020 gathered small electronic devices from all over Japan in order to make 5,000 gold, silver and bronze medals.

In February 2017, Tokyo 2020 announced that they would be making their medals out of recycled electronics. They asked the public to donate their old or unwanted phones. Gold, silver, and bronze were all extracted from the phones by using the same method used in the Vancouver 2010 Paralympic and Olympic Winter Games.

The Tokyo Organizing Committee stated that they hope that their project to recycle small consumer electronics and their efforts to contribute to an environmentally friendly and sustainable society will become a legacy of the Tokyo 2020 Games.

The Organizing Committee also said that the medals symbolize the energy of athletes, as well as the diversity of the games, while their brilliant signifies the warm glow of friendship.
