Japan is exploring the feasibility of forging the Olympic 2020 medals using precious meta ls salvaged from electronic waste.
日本正在探索使用电子垃圾中回收利用的贵金属来制造2020年东京奥运会的奖牌。
Members of Japan's Olympic organising committee tabled the idea to government officials and companies earlier this year, local media reports said.
Olympic host cities have traditionally obtained the meta l from mining firms.
But Japan, which lacks its own mineral resources, is keen to take the theme of a sustainable future a step further.
The International Olympic Committee (IOC) has developed strict criteria for the world's greatest sporting event, and this extends to how the medals should be produced.
The Rio Olympics, for example, used gold that was extracted without the use of mercury and a third of the silver and bronze used came from recycled sources.
