Video explanation of the present situation of traditional garbage disposal

Garbage classification is to classify garbage in a recyclable and non-recyclable way. Human beings produce a lot of garbage every day, which is not classified and recycled, and is discarded at will, causing environmental pollution. Garbage classification is to put garbage into the source, and make it become a resource again through sorting, cleaning and recycling.

Most of the garbage disposal methods are traditional stacking and landfill, covering tens of thousands of acres; Moreover, mosquitoes and flies fly around, sewage overflows and stinks, which seriously pollutes the environment. Therefore, classified collection of garbage can reduce the quantity and equipment of garbage disposal, reduce the disposal cost and reduce the consumption of land resources, which has social, economic and ecological benefits.

Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.

Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body. Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can reduce the harm.

The significance of garbage classification:

1. Separating kitchen waste containing perishable organic components provides high-quality raw materials for garbage composting and produces high-quality organic fertilizer, which is beneficial to improving soil fertility and reducing fertilizer application.

2. The kitchen waste with high moisture content is separated, which improves the incineration calorific value of other wastes and reduces the difficulty of secondary pollution control in waste incineration.

3. Classifying harmful waste reduces the contents of heavy metals, organic pollutants and pathogenic bacteria in garbage, which is beneficial to the harmless treatment of garbage and reduces the risk of water, soil and air pollution in garbage treatment.

4. Different kinds of garbage are diverted, which greatly reduces the amount that eventually enters the sanitary landfill and prolongs the service life of the landfill.

5. Increase the proportion of waste recycling, reduce the demand for raw materials and reduce carbon dioxide emissions.
