We have a lot of waste things in our daily lives, such as used paper, old newspapers, used plastic bags, cans, bottles and so on. It is important to make good use of the waste things. There are some ways to reuse the waste. We can use the used plastic bags to put our family rubbish. We can make the empty tins into ashtrays (烟灰缸). We can also make the used bottles into different kinds of handiwork (手工制品). That will make our rooms more beautiful. If we don't know how to reuse the waste, we can sell them to the recycling station. There are many other ways to reuse the waste. If we try our best to recycle the waste, there will be less waste and less pollution in our lives.
