What kind of rubbish is in the four-color trash can?
The yellow trash can mainly recycles glass waste, such as wine glasses, wine bottles, flat glass, glass oil bottles and a series of glass products;
The orange trash can mainly collects harmful waste, such as used batteries, used lamps, expired drugs, paint buckets and so on, and harmful waste.
Blue trash can mainly collects recyclable garbage, such as paper, plastic bottles, iron blocks, etc.
Green is mainly to collect some garbage other than the above, such as cigarette butts, diapers, kitchen waste, dust and so on.
The advantages of garbage sorting treatment are as follows:
Reduce land erosion
Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage sorting, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.
Reduce pollution
In China, sanitary landfill or even simple landfill is mostly used for garbage disposal, covering tens of thousands of acres; Moreover, insects and flies fly around, sewage overflows and stinks, which seriously pollutes the environment.
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 also reduce the harm.
turn waste into treasure
China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls and billions of disposable chopsticks every year, accounting for 8- 15% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. A ton of cans can be melted to form a ton of good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30%~40% of domestic garbage can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.
Moreover, other substances in garbage can also be transformed into resources, such as food, vegetation, fabrics, etc., which can be composted to produce organic fertilizer; Garbage incineration can generate electricity, heat or cool; Bricks and lime soil can be processed into building materials and so on. If we can fully tap the resource potential contained in the recycling of domestic waste, Beijing alone will get an economic benefit of 1 1000 billion yuan every year. It can be seen that the best way to solve the garbage problem is to classify and recycle the garbage generated in the consumption link in time.
