Smartphones and other electronic devices are ubiquitous, even while the precious metals that producers use to create them are becoming scarcer, and so the organizers of the Tokyo 2020 Summer Olympic Games are hoping to make use of the vast "urban mine" in Japan. By "urban mine," the organizers of Tokyo 2020 are referring to the huge amount of discarded electronics in the country.

Gold, silver, and copper, the three metals that make up the gold, silver, and bronze medals, respectively, are all common in electronics equipment. In London 2012, the medals were made from about 10 kilograms of gold, 1,210 kilograms of silver, and 700 kilograms of copper. According to estimates from the Japanese organizers, discarded electronics equipment in the country contained 143 kilograms of gold, 1,566 kilograms of silver, and 1,112 tons of copper.
