1. What is garbage classification
The garbage classification is to classify the garbage according to the recycling and reuse and non -recycling and re -use method. Human beings will produce a large amount of garbage daily, and a large amount of garbage is recovered without classification and arbitrarily discarding will cause environmental pollution. The garbage classification is to classify the garbage classification at the source, and re -become a resource through classification of clearing and recycling.
2. my country's garbage classification method
(1) Recycled garbage: It mainly includes five categories: waste paper, plastic, glass, metal and fabric.
Waste paper: It mainly includes newspapers, journals, books, various packaging paper, office paper, advertising paper, carton, etc., but pay attention to paper towels and toilets.
Plastic: It mainly includes various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste skin, etc.
Glass: It mainly includes various glass bottles, broken glass, mirrors, light bulbs, etc.
Fabric: It mainly includes abandoned clothes, tablecloths, facial washing towels, schoolbags, shoes, etc.
Metal objects: mainly include cans, canned boxes, etc.
(2) Kitchen waste garbage: Including food waste, bones, bones, vegetable roots, peels, peels and other food wastes, it can be composed of 03 tons of organic fertilizer per ton.
(3) Harmatic garbage: Including waste batteries, waste sunlight tubes, waste silver thermometers, expired medicines, etc. These garbage require special safety treatment.
(4) Other garbage: including brick and tile ceramic, residue, and bathroom waste other than the above -mentioned types of garbage
The use of paper and paper towels such as paper and paper towels can effectively reduce pollution of groundwater, surface water, soil and air.
Third, the advantages of garbage classification
Most of the methods of garbage treatment are in traditional stacking and landfilling methods, occupying tens of thousands of acres of land: and mosquito flies fly chaotic, sewage overflows, odor smoked, and severely polluted the environment. Therefore, the collection of garbage classification can reduce the amount of garbage treatment and treatment equipment, reduce the cost of treatment, reduce the consumption of land resources, and have the benefits of social, economic and ecological aspects.
The advantages of garbage classification treatment are as follows:
1. Reduce occupation: Some substances in domestic waste are not easy to degrade, causing the land to be severely eroded. The classification of garbage, removing substances that can be recycled, not easy to degrade, and reducing the number of garbage by more than 60%.
2. Reduce environmental pollution: The waste battery contains toxic substances such as metal mercury and cadmium, which will cause serious harm to humans: waste plastics in the ten soil will cause crop production to reduce production: abandoned waste plastics are eaten by animals, causing animal death The accident occurred. Therefore, recycling can reduce harm.
3 Gets waste into treasure: China uses plastic fast-food boxes to 4 billion yuan each year, with a instant noodle bowl of 5-700 million, and one billion pairs of disposable chopsticks, which account for 8-15%of domestic waste. 1 ton of waste plastics can be refined 600 kg of diesel. Recycling 1500 tons of waste paper can be removed from cutting forests used to produce 1,200 tons of paper. 30%-40%of production waste can be recycled and should cherish the resources of this small.
Fourth, the meaning of garbage classification
1. Classification of kitchen garbage, which is dominated by rotten organic components, provides high -quality raw materials for garbage compost, and high -quality organic fertilizer in the production office is conducive to improving soil fertilizer and reducing the amount of fertilizers.
2. The separation of kitchen garbage with a high moisture -containing rate has increased the incineration heating value of other garbage, reducing the difficulty of the secondary pollution control of waste incineration;
3. Categorize harmful waste, reduce the content of heavy metals, organic pollutants, and pathogenic bacteria in garbage, which is conducive to the harmless treatment of garbage, and reduces the risk of water, soil, and air pollution for garbage treatment;
4. Digitalize different types of garbage, which greatly reduces the amount of dyeing in sanitary landfills, and extends the service life of the landfills;
5. Increased the proportion of waste recycling, reducing the demand for raw materials, and reducing the discharge of carbon dioxide.
