史上最環保奧運! 東奧 5000 面獎牌由 7.9 萬公噸廢物製成

2020 東京奧運堪稱是史上最環保的奧運,除了選手村的床是紙做的, 5000 面的獎牌也是利用 7.9 萬公噸的電子廢物製成。東奧委員會日前在官方推特發文提醒得獎選手「別再咬獎牌」,讓本屆獎牌的生產原料再度成為熱議焦點。

據日媒報導,本屆奧運為永續環保理念,自 2017 年,日本全民總動員,展開奧運獎牌金屬回收計畫,東奧委員會設置近 7000 個回收站,耗時 2 年,最終回收超過 600 萬支廢棄手機及計算機等其他廢棄小型電子設備,共 7.9 萬公噸的電子廢棄物,經過特殊的鎔鑄技術,從中提煉出 32 公斤黃金、 2500 公斤銀合 2200 公斤銅製成 5000 面獎牌。其中,提煉出的 32 公斤黃金,市價超過新台幣 5000 萬,千萬別小看廢物的能力。 

事實上,早在 2010 年的溫哥華奧運就開先例,首度在奧運獎牌中加入微量電路板和電腦零件回收提鍊的金屬,到了 2016 年的里約奧運也延續環保,約有 30% 的銀、銅來自回收再利用。
