Japan is exploring the feasibility of forging the Olympic 2020 medals using precious metals 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.

当地媒体报道，日本奥林匹克组织委员会的成员们在今年早些时候将此想法正式提交给了政府官员和相关公司。

Olympic host cities have traditionally obtained the metal from mining firms.

奥林匹克主办城市向来是从矿产公司购入金属。

But Japan, which lacks its own mineral resources, is keen to take the theme of a sustainable future a step further.

但是日本作为一个矿产资源缺乏的国家，致力于更深入地贯彻可持续未来的主题。

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.

国际奥委会（IOC）为奥运会制定了严苛的标准，其中涵盖了如何制作奖牌。

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.

例如，里约奥运会的金牌就是在无水银的情况下提炼而得，三分之一的银和铜来自可回收材料。
