With the improvement of people's living standards and the increase in consumption level, the garbage problem in China becomes increasingly urgent. Many cities are surrounded by garbage. Confronted with the growing garbage output and deteriorating environment, the Chinese government is implementing the policy of garbage classification with great effort. Garbage classification means dividing garbage into recyclable and unrecyclable, and requires people to put garbage into different trash cans so that it can become new resources through different ways of cleaning, transporting and recycling. It can reduce not only the amount of garbage that needs to be disposed of, but also the deposing cost and the usage of the land, benefiting our society, economy, and environment.
