　　You might not think much about where your garbage goes. But now you might want to know. On July 1, Shanghai introduced a new garbage-sorting policy(垃圾分类政策). People there need to put different kinds of garbage into different bins. Other cities in China will do the same soon.
Garbage sorting is a big problem because there is too much garbage these days. It is bad for our environment. In fact, we can make use of some garbage again. But first, we need to sort it.
For example, if you put an old battery(电池) into the “harmful waste” bin, people can use it to make new batteries. But if you don’t, the battery will end up somewhere else. Then, it will pollute the environment.
Garbage sorting and recycling around the world
Germany: There are big machines in supermarkets. You can put bottles in the machines and get money back.
Japan: A truck playing music comes to people’s doors to pick up their garbage. There are eight or more kinds of garbage. If you sort any of them wrong, you will get a notice on your door.
Indonesia: People can take buses for free if they give plastic bottles to bus stations. An hour-long bus ride costs three large bottles.
Four kinds of garbage in Shanghai
Recyclable garbage includes paper, books, plastic items, and glass bottles. Harmful garbage includes lamps, batteries, and other things with harmful chemicals(化学品). Wet garbage usually comes from the kitchen, such as food and vegetables. Dry garbage is anything you cannot put into the other three bins, pens and towels, for example.
