标准答案
A drink can. Swallow the contents then throw the can away---that is the deal often enough nowadays.
A pretty poor deal ---for people's pockets and for the environment. And this is no solution either.
Recycling is the only proper way. A magnet cleanly separates the tin from the aluminum.
The aluminum recovered in this smelting furnace exclusively from used cans saves almost 95% for the production of the new cans. Aluminum can be remelted as successfully and as often as glass.
喝完饮料,将易拉罐随手一扔了事。这样的情形随时可见。
这种做法大到对环境,小到对个人都不是上策。更不解决任何问题。
循环再生是惟一的好办法。磁铁将锡与铝分开。
利用废弃的易拉罐再次提炼铝来生产新的易拉罐节约了约95%的成本。铝和玻璃一样可被熔解。 |
