The meaning of garbage classification:
1. Reduce waste
The so-called garbage is actually a resource. When you put it in the wrong place, it is garbage. Waste paper, waste plastic, waste metal, waste glass, and old clothing can be recycled and processed into corresponding raw materials; leftover rice, leftover vegetables, and melon and fruit peels can be processed into organic fertilizers to produce green vegetables and grains. ;Old home appliances and mobile phones can be dismantled to extract precious rare metals and other raw materials; old furniture can be repaired and reorganized and then sold in the second-hand market; even decoration waste can become valuable materials for reclamation and pit filling; other highly combustible wastes It can be incinerated for power generation; the garbage that cannot be disposed of will go to landfill. In developed countries such as Sweden, landfill waste accounts for only 1% of the country's total waste, while in my country, landfill waste is as high as 90%, occupying tens of thousands of acres of land. It can be seen that through garbage classification, the recyclable garbage is classified and handed over to relevant enterprises and units for processing, which will effectively reduce the amount of real garbage.
2. Save resources
Our forests are getting fewer and fewer because trees are being cut down for raw materials; our oil needs to be imported in large quantities because our own oil production is not enough; our mountains are getting balder because the demand for minerals is getting stronger and stronger... .... If the used commodities are eventually discarded permanently, then in order to continue production, only more and limited resources on the earth can be consumed. However, if the used commodities are recycled, decomposed and processed into raw materials, it can be Recycling can effectively reduce the dependence on trees, oil, minerals and other resources. According to research, 1 ton of waste plastic can be recycled into 600 kilograms of diesel; 1,500 tons of waste paper can be recycled to save the trees for the production of 1,200 tons of paper; one ton of cans can be melted into a ton of good aluminum blocks, It can save 20 tons of aluminum ore. According to statistics from relevant departments, there are about 3 million tons of scrap iron and steel and 6 million tons of waste paper in my country every year. And there are more than 6 billion waste dry batteries that we often discard every year, which contain a total of more than 70,000 tons of zinc and 100,000 tons of manganese dioxide. If these resources can be reused, they will become huge social wealth.
3. Avoid pollution
Garbage is not only unsightly and affects the image of the city, but some garbage is also toxic and harmful. For example, the aforementioned plastic will cause soil compaction, and burning plastic will produce high carcinogen dioxin; cadmium in nickel-cadmium batteries and lead-acid batteries The lead in the alkaline zinc-manganese battery and the mercury as an additive are all toxic metals. According to research, the cadmium in a nickel-cadmium battery can pollute the water in three standard swimming pools; cosmetics, paints, fluorescent tubes, energy-saving lamps , mercury thermometers, expired medicines and other improper handling are environmental killers, seriously endangering people's health. Through garbage classification, these substances can be concentrated in professional institutions for harmless treatment, and some toxic and harmful garbage can be turned into treasures after treatment.
