A new rubbish sorting system has been put into use in Zixinhuating Community in Hangzhou. Local people not only sort their rubbish, but also put QR codes(二维码) on it.

In Hangzhou, every family is provided with three rubbish bins—the grey lid bin for “recycling” like steel and glass, and the green lid bin for “green waste” such as grass and leaves and the red lid bin for harmful waste, like batteries. On the streets, the bins are printed with pictures of the things that are allowed inside. It makes recycling quite easy.

“When the QR codes are seen, the bin will open by itself and I just throw the rubbish in it. Then 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 also 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 buried in soil or burned without being sorted. Landfills 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. 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.
