Tokyo Olympics 2020 committee unveiled the medals to be awarded to the winners in the Olympics 2020 which will start exactly one year after today. As earlier announced that all the medals will be made using the material harvested from old gadgets the Tokyo 2020 collected enough unused gadgets to extract the required amount of precious metals.
The medals were designed by Junichi Kawanishi, who won the competition for designing the medals with entries from more than 400 professional designers and design students.
The Tokyo 2020 organizing committee launched a two-year campaign in April 2017 to collect donated electronic gadgets from the public in order to harvest the required materials.
78,895 tons of gadgets were received in total, including 6.21 million mobile phones, and this resulted in the extraction of 32kg of gold, 3,500kg of silver, and 2,200kg of bronze.
The medals are all 85mm in diameter, measuring 7.7mm at their thinnest part and 12.1mm at their thickest. The gold medals use more than 6 grams of gold plating on pure silver, the silver medals are made from pure silver, and the bronze medals use a red brass alloy made up of 95-percent copper and 5-percent zinc.
IOC regulations mandated that the design should include the iconic five rings symbol, the official name of the games, and the Greek goddess of victory Nike in front of the Panathenaic stadium.
