Japan has already unveiled the medals of the Tokyo Games that will take place in 2020. This time, Japan wanted to give a twist to these medals and wanted to give them an ecological component that many people will appreciate.

In April 2017, the committee in charge of organizing the Tokyo 2020 Olympic Games carried out a 2-year campaign to collect unused electronic devices. These would be donated by members of the Games public to harvest the metals with which these medals would be made.

After the collection campaign, a total of 8,895 tons of devices were collected. Of this huge amount, 6.21 million were mobile phones, resulting in the extraction of 32 kg of gold, 3,500 kg of silver and 2,200 kg of bronze.

These medals use a different composition depending on their category. Gold medals use 6 grams of gold-plated on pure silver, silver medals are made of pure silver and bronze medals use a red brass alloy composed of 95 percent copper and 5 percent zinc.
