    The 32nd Summer Olympic Games. will be held in Tokyo, Japan in 2020. Recently, the organizers showed the medals (奖牌) to be presented at the Games. The design of the medals is simple, but they look shiny from any direction. And do you know that these medals were made from old smartphones and other electronics (电子产品)?

The idea was first introduced in 2016 by a group of young Japanese environmentalists. They wanted people to pay attention to the amount of e-waste created by the country's tech-loving people who change their electronics very often. To protect the environment, the Organizing Committee started the "Everyone's Medal" program in April 2017. The program encouraged people to drop used electronics in certain places. By the time the collection ended in March 2019, 78,985 tons of used smartphones and other small electronics had been collected. The program finally got 32 kilos of gold, 3,500 kilos of silver (银), and 2,200 kilos of bronze-more than enough metals (金属) to make every medal.

The Olympic Committee hopes the Tokyo 2020 Olympic medals will draw people's attention to the fast increase in e-waste not just in Japan, but worldwide and cause people to rethink upgrading (更新) electronics unnecessarily.

Though Japan is the first Olympic host country to make all the medals by using metals from used electronics, it is not the only one to think of the idea. Brazil made 30% of the silver and bronze medals for the 2016 Summer Olympics from recycled materials(回收材料).
