Medals for the Tokyo 2020 Olympic and Paralympic Games will be made from recycled mobile phones in an attempt to promote sustainability and reduce costs.
The Japanese public will be asked to donate old phones and similar appliances to the campaign, with more than two tonnes of gold, silver and bronze needed to produce the 5,000 medals that will be awarded at the Games.
Collection boxes will be available in local offices and telecoms stores from April in Japan, and will remain there until the amount of metal required has been collected.
Traditionally, host cities have sourced the metal from mining firms.
“A project that allows the people of Japan to take part in creating the medals is really good,” said Koji Murofushi, Tokyo 2020 sports director.
“There is a limit on the resources of our earth, so recycling these things will make us think about the environment.”
