From July lst, 2019, people in Shanghai must follow a new law. They can't throw away all the rubbish together. They need tosortrubbish.
According to the law, there are four kinds of rubbish: dry rubbish, wet rubbish, recyclable rubbish and harmful rubbish. If people don't sort the rubbish, they will get a fine. For a person, the fine can be 200 yuan. For a company, the fine can be 50,000 yuan.
Recycling waste is actually a complex system where separation (分开) and collection are just the first steps. No separation equals incineration (焚烧). For many people, it's difficult to sort their rubbish. So how do we sort the rubbish? Here are some ideas about it. For example, we can use paper again. So it is recyclable rubbish. Batteries are harmful rubbish, because they are bad for people and environment. The leftover (剩下的) food, flowers, and trees are wet rubbish. Finally, if the rubbish isn't recyclable rubbish, bad rubbish or wet rubbish, it is dry rubbish.
