With the rapid development of China's economic and urban construction, the continuous increase of urban population, and the significant improvement of people's living standards, the amount of household waste generated is also increasing day by day, and the harm to the environment has become increasingly serious. So it has become an urgent task to handle urban household waste in an environmentally friendly and economical manner. At present, the general methods of garbage disposal are land disposal, river and ocean disposal, landfill, composting and incineration, and recycling.

At present, the majority of garbage disposal is mainly through landfilling, accounting for over 70% of the total processing capacity. Most countries in the world, especially underdeveloped ones, adopt this method for waste disposal. The characteristics of this method are low operating costs, simple operation, and large processing capacity. But there are significant drawbacks. Firstly, it occupies a large amount of land, wastes land resources, makes site selection difficult, and incurs high land acquisition costs; The second is the waste of a large amount of resources contained in garbage. Human made garbage will be transformed into "resources that cannot grow and huge wealth that can be thrown away", which cannot meet the demand for resource utilization; Thirdly, environmental pollution is severe. Due to the fact that most existing landfill sites cannot meet the requirements of sanitary landfill, bacteria and toxins in the garbage continue to seep downwards, polluting the land and water quality. With the increase of accumulation and the continuation of time, the pollution spreads to the surrounding areas and deep underground layers, causing harm for thousands of years. The toxic and odorous gases dispersed by the garbage spread to the surrounding areas, forming three-dimensional pollution in the air, surrounding areas, and underground.

Although a few "sanitary landfills" have been built in many developed countries and some more developed cities in China, reducing some pollution, there are still many environmental pollution problems caused by imperfect technology that cannot be fundamentally solved. So the advantages of the garbage sorting equipment used in garbage sorting are highlighted. By using garbage sorting equipment to recycle and process household waste, precise classification of urban household waste can be carried out, and then appropriate methods can be used according to the different properties of the classified waste, so that it can be regenerated and reused, truly achieving harmless and reduced waste, turning harm into benefit, and reducing human demand for natural resources, achieving sustainable utilization of resources. Therefore, the development prospects of garbage sorting equipment are very promising.
