Japan manages urban environmental pollution in this way.

How to reduce urban environmental pollution and create a low-carbon and livable city has become a common topic faced by all countries in the world. In this regard, Japan has many successful experiences and practices. Among them, the most successful example is Minamata's comprehensive urban environmental governance system. Due to its effective management efficiency and governance measures, the market was elected as "environmental model city" in Japan.

Then, how does Minamata carry out urban environmental pollution control?

It starts with a serious environmental pollution incident in 50s. At that time, Japan was at the center of heavy chemical industry and achieved rapid economic growth. Because of the mercury contained in sewage discharged from the chemical plant, the pollution caused by a chemical plant caused a public nuisance called "the MISSHA disease", and many of the victims were in pain. So far, many victims have been seriously affected by sequelae.

In order to completely change the urban pollution situation, Minamata began to build "environmental Park" and fully implemented the "Minamata environmental protection park plan". A total of 8 enterprises were gathered in the park to recycle and reuse domestic garbage, cans, waste oil and construction garbage. For this reason, the market has invested a lot of manpower and material resources, and has set a number of key points, such as realizing industrial transformation, developing the natural ecosystem and biodiversity, and establishing a resource recycling oriented social system.

The environmental control measures in the market started with garbage sorting. In traditional household garbage classification, combustible garbage and non-combustible garbage are treated differently. This is mainly to realize the recycling of garbage. Taking the public as the main body, 20 categories of regulations are formulated. In urban areas, every 50 to 100 households set up a resource garbage station, the city has built a total of 300 such garbage stations.

When garbage sorting was first introduced, many citizens complained that 20 kinds of sorting were too troublesome. However, after years of implementation, the public's awareness of environmental protection has increased, and they have taken the initiative to classify garbage. Moreover, communication among communities has gradually become active, such as the convening of "waste collection point meetings" and symposiums at resource and environment stations.

In addition to garbage sorting, the market has also carried out a series of activities focusing on the community reutilization Promotion Committee. Such as recycling activities, opening flea markets and exchanging items that are no longer needed.

With the ISO14001 certification of the international environmental management system, the city's environmental protection measures have gradually increased. For example, through the adoption of unique environmental protection measures to promote the development of environmental verification activities, the establishment of Minamata's original version of the public environment ISO system. At the same time, we will actively organize international collaborative activities on environmental protection, such as receiving overseas visitors for inspection and further study, and holding seminars and lectures on environmental protection in Asia. In addition, every year, the training course will be held by professionals from Japan International Cooperation Agency. Students from different countries can learn about environmental protection here. Through these activities, the market has spread its environmental experience and knowledge accumulated over the years to all parts of the world.

Years of fruitful management experience and various measures taken in a wide range of fields have been widely recognized by the public at home and abroad.

Now, Minamata is committed to studying how to further refine household waste classification, including recycling rare metals used in small electronic devices such as mobile phones, game consoles and tablet computers. In addition, the municipal government also plans to build second "green parks" outside the existing "environmental protection park" so as to attract more enterprises that are engaged in recycling and recycling to the park.
