What are the economic benefits brought by domestic waste management systems？

Comprehensive utilization of domestic waste has become the development direction of waste treatment. Garbage classification is the premise of comprehensive utilization of garbage. The research on waste management system has been listed as one of the national key projects.
So far, domestic waste treatment is in the research of incineration and landfill equipment, and there is less research on waste sorting equipment. The purpose of garbage sorting machine research is to effectively classify mixed garbage, separate a small amount of impurities in the garbage components, and obtain relatively single components, or separate a small amount of garbage components from mixed garbage, which is conducive to garbage recycling and subsequent processing.
The trommel screen has high efficiency and is suitable for the separation of materials of different sizes, but the screen surface needs to be disassembled and replaced. Disc screen can avoid the trouble of disassembly and replacement. By adjusting the distance between the disc shafts, it can adapt to the separation of materials of different sizes, and it has the ability to self-clean without other cleaning devices.
Then there is the air separator, which is also a very important separator. By adjusting the air speed, the separation of waste materials of different densities can be achieved, which is very suitable for the separation of some lightweight materials. The working principle of the magnetic separator is relatively simple, it utilizes the magnetic properties of metal, but the layout in the sorting process is very critical, and the reasonable layout of the sorting equipment can achieve more with less.
In addition to screening machines and magnetic separators, other equipment is also used for waste sorting. In short, with the progress and development of society and economy, garbage recycling will receive more and more attention, the research on garbage classification equipment will be more and more in-depth, and garbage classification will be more and more detailed for better recycling, garbage The purpose of sorting is to separate inorganic and organic matter for better recovery of energy and materials.
