One of the benefits and significance of garbage classification
1, reduce the occupation of land
Some of the substances in the household garbage are not easy to degrade, so that the land is seriously eroded.
The classification of garbage removes the recyclable and non-biodegradable substances and reduces the amount of garbage by more than 60%.
2, reduce pollution
Currently, China's garbage disposal mostly adopts sanitary landfill or even simple landfill, occupying tens of thousands of acres of land; and insects and flies fly, sewage overflows, the stench of the sky, seriously polluting the environment.
The waste plastics in the soil will lead to crop yield reduction; abandoned waste plastics are accidentally eaten by animals, resulting in the death of animals from time to time.
So recycling can also reduce the harm.
3, waste into treasure
1 ton of waste plastic can be back to refining 600 kilograms of diesel fuel, recycling 1500 tons of waste paper, can be exempted from cutting down for the production of 1200 tons of paper in the forest.
One ton of cans can be melted down to form a ton of very good aluminum blocks, and 20 tons of aluminum ore can be mined less.
30% to 40% of household waste can be recycled.
Other substances in the garbage can also be converted into resources, such as food, grass, trees and fabrics can be composted to produce organic fertilizers; garbage incineration can be used to generate electricity, heating or refrigeration; bricks, tiles and ash can be processed into building materials and so on.
A variety of solid waste mixed together is garbage, sorted out is a resource.
The garbage generated in the consumption chain is the best way to solve the garbage problem if it is sorted in time and recycled.
Two, non-recyclable garbage what
Non-recyclable garbage generally use separate recycling or landfill disposal.
1, waste paper: mainly including newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cardboard boxes, etc., but note that paper towels and toilet paper due to water solubility is too strong not to be recycled.
2, plastic: mainly including a variety of plastic bags, plastic packaging, disposable plastic lunch boxes and cutlery, toothbrushes, cups, bottles of mineral water.

4, metal objects: mainly including cans, can boxes, toothpaste skins and so on.
5, fabric: mainly including discarded clothes, tablecloths, washcloths, schoolbags, shoes and so on.
It can be seen that non-recyclable garbage refers to waste that contains heavy metals that are harmful to human health, toxic substances, or waste that poses a real or potential hazard to the environment. It includes batteries, fluorescent tubes, light bulbs, mercury thermometers, paint buckets, some home appliances, expired medicines, expired cosmetics and so on.
