Foreigners who have just arrived in Japan will be impressed by its amazing garbage classification. At first glance, Japan's garbage classification has the following characteristics. The first classification of Japanese garbage is fine classification and timely recovery. The largest classification includes, no, resource class, coarse class, harmful class, and then subdivided into several subprojects, each subproject can be subdivided into grandchildren, and so on. Combustible: in short, combustible-but not including plastic, rubber fragments, general leftovers, and some combustible domestic garbage. Resources: newspapers, books, plastic beverage bottles, glass beverage bottles, nonflammable: discarded small household appliances (electric kettles, tape recorders), clothes, toys, ceramic products and iron containers. Coarse categories: large furniture, large electrical appliances (TV sets, air conditioners), bicycles. A few years ago, Yokohama further subdivided the garbage classification from the original five categories into ten categories, and sent you a 27-page manual with many articles. Try a few cases: lipstick belongs to genus, but the used lipstick tube belongs to small metal; The kettle belongs to metal, but 12 inch belongs to small metal, and more than 12 inch belongs to big waste; Socks, if belonging to one genus, if belonging to two genera, and "not worn out, left and right feet match", belong to old materials; Ties are also old materials, but only if they are "washed and dried". However, this is a drop in the bucket compared with Shangsheng Town in Tokushima Prefecture. The town has divided the garbage into 44 categories, and plans to achieve the goal of "zero garbage" by 2008. In terms of recycling, some communities have a row of classified garbage bins, while others have no garbage bins. Instead, it is stipulated that specific garbage bags should be placed in specific places at specific times of the week and taken away by special personnel in time. For example, in the port area of Tokyo, combustible garbage is collected every Wednesday and Saturday morning, non-combustible garbage is collected on Monday morning, and resource garbage is collected on Tuesday morning. Many communities stipulate to throw garbage before 8 am, and some relax to noon, but they are all taken away on the same day to avoid polluting the environment or attracting pests and crows. Second, management is in place and measures are appropriate. When foreigners arrive in Japan, they have to register at their place of residence, and then they often get local regulations on littering. When renting a house, Dong may hand over the key to the No Littering Ordinance at the same time. At the end of the year, some administrative districts will issue calendars to residents for the next year. Some dates are marked with colors such as yellow, green, blue, etc. Each color is shown below to represent which kind of garbage can be thrown on which day. In some public places, you will often see a row of trash cans that read: paper cups, plastic, and Japanese, English, Chinese and Korean are written on each trash can. Third, everyone should be careful. Good habits are not formed in a day. Japanese children have been taught by their parents and schools how to deal with garbage correctly since childhood. If you don't throw garbage according to the regulations, you may be dissuaded by the staff and the surrounding pressure. Japanese residents are meticulous in throwing garbage, and they are very strict: waste newspapers and books should be neatly tied, wet garbage should be drained, sharp objects should be wrapped in paper, and used spray cans should be pierced with a hole to prevent them from appearing. Fourth, waste utilization, energy conservation and environmental protection. After the sorted garbage is recycled by a special person, the newspaper is sent to a paper mill to produce recycled paper. Many Japanese people are proud that their business cards are printed with "Use recycled paper". Beverage containers are sent to relevant factories respectively to become renewable resources; Waste electrical appliances are sent to special decomposition treatment; Combustible garbage can be used as fertilizer after burning; Noncombustible garbage can be used as resource-based raw materials after compression and harmless treatment. The packaging box of Japanese goods has been marked with what kind of garbage it belongs to, and there are even hints on the milk box: wash it, open it, dry it, fold it and throw it away. In terms of garbage sorting, Japan is at the forefront of the world. The severe environmental pollution in the 1960s "forced" the first-class environmental protection technology, and the profound oil crisis in the 1970s gave birth to the best energy-saving technology. In the process of overcoming crisis after crisis, Japan has surpassed other advanced countries one by one. An old Japanese friend of mine is stationed in western Europe. He talked about the "embarrassment" of getting gifts every year when he goes back to China to visit relatives. This is because his relatives and friends have changed from the initial pursuit of Western European products to world-class domestic products like seiko watch, Toyota and Nikon cameras. This achievement not only has an efficient and reasonable management system, but also depends on the spirit and motivation of the general public. The seriousness of garbage sorting is undoubtedly the most brilliant part. The Japanese are the most earnest and meticulous, which is vividly demonstrated in many aspects. For example, the floor tiles on the sidewalks of various business districts in Tokyo will not collapse unevenly for decades, and architects require that the invisible places such as the back of the stair blank should be neat and smooth, and so on. A wise man corrects his own mistakes through the mistakes of others. The example of Japan above gives us a lot of inspiration. As far as garbage classification is concerned, the hardware in most parts of China is far from being compared with that in Japan, but the bigger gap is probably in the software, that is, in the understanding of garbage classification with the public, in the construction of garbage classification system, and in the earnest spirit and consciousness of every citizen on environmental protection and energy conservation. From this point of view, only by abandoning troublesome concepts, thinking habits and low standards of being content with the middle stream can we catch up with the world's advanced level in garbage classification, eliminate the "three cares" dead angle in urban management, and have special personnel to control the phenomenon of dirty, chaotic and poor.
