Waste sorting is the process of placing garbage in different categories according to "recyclable" and "non-recyclable", and turning it back into resources through sorting, transportation and recycling.
2, the reasons for the classification of garbage disposal:
1) economic aspects: the classification of garbage can be recyclable garbage into treasure, so that it can be reused as a new resource. For example: we drink the rest of the cans belong to recyclable garbage, a ton of cans can be melted into a ton of very good aluminum block, can be less mining 20 tons of aluminum ore.
2) Occupancy: waste classification is conducive to reducing the consumption of land resources. Some substances in domestic garbage are not easy to degrade, making the land seriously eroded. Garbage classification, remove the recyclable, not easy to degrade the material, reduce the amount of garbage up to 60% or more.
3) Environmental pollution: garbage thrown everywhere will cause insects and flies, sewage overflow, foul smell, some garbage contains heavy metals and other toxic substances, seriously polluting the environment. Reasonable classification and collection of garbage can reduce the amount of garbage disposal. For example:
Discarded batteries contain metals such as mercury, cadmium and other toxic substances, which can cause serious harm to human beings, so recycling can reduce the harm.
3, how to classify garbage:
1) First of all, it should be clear what is recyclable garbage and what is non-recyclable garbage.
Recyclable garbage mainly includes five categories: waste paper, plastic, glass, metal and fabric. Waste paper: mainly including newspapers, periodicals, books, all kinds of wrapping paper and so on, but pay attention to paper towels and toilet paper due to the water solubility is too strong not to be recycled. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos flasks and so on. Metals: mainly cans, can containers, etc. Fabrics: mainly include discarded clothes, tablecloths, washcloths, school bags, shoes, etc. Kitchen waste includes leftovers, bones, vegetable roots and leaves, fruit peels and other food wastes, which are composted by biotechnology in-situ treatment. Recycling through comprehensive treatment can reduce pollution and save resources.
2) Precautions to be taken when putting out garbage:
①Paper should be folded as neatly as possible to avoid kneading before the garbage is sorted and put out;
②Bottles and cans should be cleaned up as much as possible after the products in the containers are used up and then put out;
3) Kitchen waste should be bagged and put out in closed containers.
④Glass items should be placed carefully and gently to avoid breakage.
⑤After putting in the garbage can, you should pay attention to cover the lid to avoid the garbage polluting the surrounding environment and mosquitoes and flies.
