日本如何回收電子垃圾做獎牌

How does e-waste recycling work?

如何回收電子垃圾？

Discarded consumer electronics such as smartphones and tablets contain small amounts of precious and rare earth metals, including platinum, palladium, gold, silver, lithium, cobalt and nickel.

在廢棄的消費性電子產品中，如智能手機和平板電腦都含有少量的貴金屬和稀有金屬，其中包括鉑金、鈀、金、銀、鋰、鈷和鎳。

Scrap cars and home appliances such as fridges and air conditioners also contain these rarer metals, along with base metals, including iron, copper, lead and zinc.

廢棄汽車和家用電器如冰箱和空調也含有此類稀有金屬，此外還有基本金屬如鐵、銅、鉛和鋅。

Recycling or refining companies either collect or purchase tons of this e-waste and industrial scraps. They then use chemical processes to separate the various metals.

回收公司、精煉公司收集或購買上噸的電子垃圾和工業廢料。然後利用化學反應分離不同的金屬。

Much of this work takes place in developing countries such as China, India and Indonesia.

這種工作大多在發展中國家如中國、印度和印度尼西亞完成。

Does Japan have enough for 2020?

日本有足夠的電子垃圾來生產2020年的所有獎牌麼？

Japan has one of the highest recycling rates in Asia, according to OECD data. However, this mainly applies to plastic, paper and glass.

經濟合作與發展組織（OECD）的數據顯示，亞洲擁有最高回收率之一的國家就是日本。然而，他們回收的主要是塑料、紙張和玻璃。

About 650,000 tonnes of small electronics and home appliances are discarded in Japan every year, the Nikkei newspaper said. However, it is estimated that less than 100,000 tonnes is collected for recycling.

日經新聞稱每年日本有約65萬噸的小型電子設備和家用電器被丟棄。然而，其中回收再利用的預計不到10萬噸。

So for the 2020 Games, Japan will probably have to ask individual countries or companies to contribute towards the recycled metal collection effort.

所以爲了2020年的奧運會，日本可能需要請求其他國家或公司共同幫助參與回收金屬。
