The Toyko 2020 Organising Committee began collecting mobile phones and small electronics in April 2017 from Japan’s citizens and corporations.

It has now announced it will close collections on 31 March.

Approximately 5,000 gold, silver and bronze medals will be manufactured for the games.

Seven-time Olympic medallist gymnast Kohei Uchimura said he hoped the medal scheme would make people think more about their waste.

He said: “I think it is ‘mottainai’ [wasteful] to discard devices every time there is a technological advance and new models appear. In the field of sport, gymnastics techniques too have evolved as a result of the efforts made by athletes in the past.

“Tokyo 2020 Olympic and Paralympic medals will be made out of people’s thoughts and appreciation for avoiding waste. I think there is an important message in this for future generations.”

Gold and silver medals must contain a minimum of 92.5% silver, with gold medals plated with at least 6g of pure gold.
