Garbage Classification
is to classify garbage according to its recycling value
and the degree of pollution to the environment
Dividing into different categories
is conducive to garbage recycling and processing
So what is the significance of garbage classification? What are the benefits of
?
The meaning of garbage classification
1. Separate kitchen waste with perishable organic components as the main component, provide high-quality raw materials for garbage composting, and produce high-quality organic fertilizer at the production site, which is conducive to improving soil fertility and reducing the amount of chemical fertilizer application.
2. Separating kitchen waste with high moisture content increases the incineration calorific value of other wastes and reduces the difficulty of secondary pollution control of waste incineration.
3. Sorting out harmful garbage reduces the content of heavy metals, organic pollutants and pathogenic bacteria in the garbage, which is conducive to the harmless treatment of garbage and reduces the risk of water, soil and air pollution in garbage disposal.
4. Different types of garbage are separated, which greatly reduces the final amount entering the sanitary landfill and prolongs the service life of the landfill.
Benefits of garbage classification
1. Reducing land occupation
Some substances in domestic garbage are not easy to degrade, causing serious erosion of the land. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.
2. Reducing environmental pollution
Abandoned batteries contain toxic substances such as metallic mercury and cadmium, which will cause serious harm to human beings; waste plastics in the soil will reduce crop yields; discarded waste plastics are eaten by animals, resulting in animal death. Accidents happen. So recycling can reduce harm.
3. Turning waste into treasure
China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls, and billions of disposable chopsticks each year, which account for 8-15% of domestic waste. 1 ton of waste plastic can be recycled into 600 kilograms of diesel. Recycling 1,500 tons of waste paper can save the forest trees used to produce 1,200 tons of paper.
Garbage classification
How to classify
Other garbage
Other garbage includes discarded paper, plastic, glass, metal, fabric, etc. It also includes large-scale garbage such as scrapped vehicles, home appliances and furniture, and decoration waste.
Food waste
Food waste includes food waste such as leftovers, bones, vegetable roots and leaves, and fruit peels. The compost is processed on site by biotechnology, and each ton can produce 0.6~0.7 tons of organic fertilizer.
Hazardous garbage
Hazardous garbage contains heavy metals that are harmful to human health, toxic substances, or wastes that cause actual or potential harm to the environment.
Recyclables
Recyclables mainly include five categories of waste paper, plastic, glass, metal and cloth. These wastes can be recycled and reused through comprehensive treatment, which can reduce pollution and save resources.
