Today, Japan's strict and meticulous classification of domestic waste is praised by the world, which is not overnight. During this period, it has accumulated more than 40 years of experience. It can be said that the history of garbage classification in Japan is a process of continuous improvement: from the Garbage Disposal Law promulgated by 1970 to the Basic Law on the Formation and Promotion of Circular Society formulated in 2000, a series of laws and regulations have laid a good foundation for the orderly classification and treatment of domestic garbage.

At the beginning of the trial of garbage sorting in Japan in the 1970s, residents often mixed garbage and then sorted it by sanitation workers, so the cost of garbage disposal was extremely high. 1975 In Numazu City, Japan, members of residents' self-government associations were mobilized to carry out voluntary activities in garbage dumps to guide residents on how to sort and discard garbage. The "Marsh-Tianjin Method" of professional classification of domestic waste was gradually extended to Japan, and 1975 was therefore called the first year of domestic waste classification in Japan. In 1980s, Japanese waste management entered a period of correct classification and front-end control. In this century, Japan has advanced to the stage of garbage classification and treatment that attaches importance to resource reuse, which has been affirmed by all parties.

At present, Japanese domestic garbage can be roughly divided into combustible garbage, nonflammable garbage, harmful waste, and resource garbage (recyclable paper, plastic, glass, cans, etc. ) and big garbage. Every kind of garbage should be collected to the designated collection place according to the specified collection time. The garbage sorting process is also very detailed. Take mineral water plastic bottles as an example. In addition to unscrewing the lid, the wrapping paper should also be torn off and disposed of as combustible garbage. Then crush the bottle and put it in the collection place.

In addition, the garbage classification in various parts of Japan also shows some flexibility, and there is a set of regulations on the classification of small categories. For example, Minamata, which was famous for mercury pollution in the 1950s, has been refining the classification of domestic waste in recent years, and finally reached as many as 24 categories. In Shangsheng Town, Tokushima Prefecture, which is famous for its meticulous garbage classification, domestic garbage is divided into 34 categories. At present, Shangsheng Town is striving to achieve the goal of zero waste discharge and do its utmost to eliminate incineration and landfill by 2020. Such an arduous task is obviously impossible without the support of detailed garbage classification.

Uematsumachi, a small town in Japan, is one of the most beautiful members of the village alliance in Japan. The domestic waste here is divided into 34 categories.
