Last time we thought about and discussed: Garbage trucks, suction trucks, and sewage trucks have changed history, but they cannot change the status quo! (You can click to view) How can we solve the disaster of the garbage siege? Today we first look at the specific reasons for this garbage siege:
1. The method of landfill waste cannot be sustained, and the secondary pollution caused by hybrid incineration
When many cities find it difficult to find land for the construction of a new landfill site, when garbage trucks do not have a place to go, the establishment of a landfill management system that has no landfill, zero emissions, resources, and harmless use has already been placed in the hands of city managers. On the agenda. However, most people use waste (incense) incineration power generation as the breakthrough point and ultimate goal of waste disposal, and various localities have requested the on-site garbage incineration power generation project. As everyone knows, garbage mixed incineration and power generation are still unsatisfactory waste disposal methods and have been questioned by more and more people. Because garbage mixed incineration produces harmful gases or even toxic substances such as “dioxin†that seriously endanger human health, even advanced gas-fired harm removal technology cannot eliminate the secondary hazards caused by garbage mixed incineration.
2. The establishment of a landfill-free, zero-emission, resource-utilizing waste treatment system must be based on waste classification and is a prerequisite.
This is because, in order to realize the goal of no landfill, zero discharge, and 100% recycling of garbage, a thorough and effective classification of garbage must be carried out, and a thorough and effective classification of garbage should be implemented. Classification cannot be. Some people try to use mechanical equipment to classify garbage. These things cannot be done by current sewage suction trucks, suction trucks , and garbage trucks. However, practice has proved that it is impractical to look at the fineness, effectiveness, and cost of classification. Otherwise, why is it still a “garbage siege� Therefore, we should make full use of our country's abundant human resources advantage. Under the condition of not increasing the operating cost, garbage will be completely and effectively classified by humans in waste sorting sites. In such a garbage disposal system, garbage does not need to be landfilled, because all of the garbage can be recycled after being manually classified as a variety of waste products, so a large amount of landfill land acquisition, landfill construction and maintenance can be implemented, The large amount of compensation for the secondary pollution of garbage transportation and landfill sites to local residents, the purchase, use, maintenance, and even idleness of some urban waste sorting and disposal equipments has been greatly reduced, and effectively converted into the labor cost of garbage disposal workers.
3. The difficulty of manual classification of garbage and the specialization of climate and industrialization are important obstacles to the development
Many years ago, experts and some members of the community promoted the classification of garbage as an important means of garbage disposal (rather than forced promotion), but only hoped that people in the changing concept, in the gesture of throwing rubbish on the streets and families The classification in placement achieves the purpose of limited resource utilization and reduction of waste disposal. Due to the fact that there is no great expectation for the classification of garbage, it has not been studied, promoted and practiced in terms of policies and regulations and operating systems in practice. In addition to the general social psychology and social behaviors of people, there is a general characteristic of conformity and laziness, which is reflected in the attitudes and behaviors of treating waste. People do not want to categorize rubbish carefully and seriously. In addition, the existing garbage disposal operation system does not have corresponding measures to the garbage classification. For example, the garbage that has been placed in the street trash bin is still transported by the garbage collectors collected and collected by the sanitation workers. Therefore, waste classification has always been without substantive development. Naturally, it has not played its due role in the recycling and reduction of waste. It is still just a social and government expectation and propaganda slogan. It is a widely-existing phenomenon of garbage scavenging, which objectively plays a role in the partial reduction and recycling of garbage. However, garbage scavenging is a helpless social means for the disadvantaged groups in the society. It is a spontaneous and unorganized industry behavior, and it is not a real garbage classification.
It is precisely because of the above reasons that the above garbage classification was originally used as an artificial classification. Over time, as social thoughts have increasingly attached importance to the humanistic concern for human beings, and people’s quest for technologicalization and mechanization has become increasingly intensified, it seems that manual garbage classification is contrary to People-oriented humanistic spirit and science and technology as the guiding scientific spirit. Therefore, the artificial classification of garbage has not received the recognition and recognition of society and people. It is even less likely that garbage scavengers will evolve into the artificial classification of full-scale, industrialized garbage.
It seems that this is not why garbage trucks, suction trucks, and sewage suction trucks do not play a role, but why we humans themselves. Under such a background, how can the artificial classification of garbage be promoted and developed so as to play a central role in landfill, zero-emission and recycling of waste?
