If domestic garbage is piled up or landfilled in the open air, its harmful components will accumulate in the soil, diffuse through the soil pores, and cause harm to plants growing in the soil, and even make the soil seriously uncultivable. Sampling and testing of soil pollution in these landfills found that heavy metals (arsenic, cadmium, zinc, etc.) were generally high. In addition, after kitchen garbage is landfilled, the continuous fermentation of moisture and mixing with rainwater and surface water will form high-concentration soil, which also pollutes groundwater.

Therefore, in comprehensive garbage treatment plants and some landfills, the application of garbage classification systems in garbage pretreatment and recycling will become a development trend.

Garbage sorting equipment is a set of garbage sorting lines with different garbage sorting functions. Garbage treatment supporting sorting equipment, including crushers (bag breakers), drum screens, distributors, dry cleaning machines, conveying equipment, manual sorting platforms, belt conveyors, air separators, magnetic separators, deodorizing towers, packaging machines, etc., can be combined according to different requirements.

There are all kinds of garbage. Although garbage sorting has been implemented, the situation is still not optimistic. Therefore, whether it is garbage incineration or landfill, there is no single solution to the problem. A better way is to sort the garbage first, classify and separate the garbage differently before recycling.
