A new rubbish sorting system (垃圾分类系统) has been put into use in Fangchengyuan Community in Beijing.Local people not only sort their rubbish，but also put QR codes (二维码)

on it.

“When the rubbish is collected and the codes are seen，I will get reward points to exchange for small gifts and even some money，”one of the local people told reporters.“It's really creative and encouraging.”

This smart system has been carried out in 350 communities in Beijing.The capital of China has joined a list of cities in the country that take action to support rubbish sorting.For example，Shenzhen and Shanghai have made laws to punish people and organizations for not sorting rubbish correctly.

China produces quite a lot of rubbish every year.Much of the rubbish is burried (填埋) in soil or burned without being ndfills (填埋场) take up a lot of land and have a risk of polluting

the soil and water nearby.And burning rubbish can produce harmful gases.Through rubbish sorting，we can reduce the use of landfills and air pollution.

What's more，rubbish sorting saves resources，which could bring economic benefits (经济利益)．For example，a ton of waste paper can be reused to make about 850 kg of paper，saving 17

trees and 50 percent of water.Because of their benefits，some countries have developed successful sorting systems.

Japan has a strict and detailed system.When people throw away a water bottle，the cap，the wrapper (包装纸) and the bottle itself have to go into three different bins.Every year，families
