Dear fellow students,

Our school has started a program of garbage classification. Different kinds of garbage are required to be sorted out and placed in different dustbins. Paper can be recycled, while leftovers can be collected as food for pigs or processed as fertilizer for plants. Above all, such harmful things as plastics and used batteries should not be mixed with other wastes.

The program is of great benefit. We will be able to save resources by making use of recyclable garbage and harmful things will not pollute our environment after special treatment.

Lets work together for a better campus!

亲爱的同学们，

我校已启动垃圾分类程序。不同种类的垃圾需要整理出来放在不同的垃圾桶。纸可以回收利用，而剩菜可以作为猪的食物收集或加工成肥料的植物。最重要的是，塑料和废旧电池等有害物质不应与其他废物混合。

这个计划有很大的好处。我们可以通过利用可回收的垃圾来节省资源，而有害的东西不会在经过特殊处理后污染我们的环境。

让我们一起努力建设一个更好的校园!
