Garbage classification is to classify garbage according to "recyclable" and "non-recyclable", and make it a resource again through classification, removal and recycling.
2. Reasons for garbage classification:
1) Economic aspect: Garbage classification can turn recyclable garbage into treasure and become a new resource that can be reused. For example, the cans we drink are recyclable garbage, and one ton of cans can be melted to form a ton of good aluminum blocks, which can save 20 tons of aluminum ore.
2) Land occupation: Garbage classification is conducive to reducing the consumption of land resources. 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%.
3) Environmental pollution: littering will cause insects and flies to fly around, and sewage will overflow with stench. Some garbage contains toxic substances such as heavy metals, which seriously pollutes the environment. Reasonable garbage sorting and collection can reduce the amount of garbage treatment. For example:
Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human beings, so recycling can reduce the harm.
3. How to classify garbage:
1) First of all, we should know what is recyclable and what is not.
Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth. Waste paper: mainly including newspapers, periodicals, books, various wrapping papers, etc. However, it should be noted that paper towels and toilet paper are too water soluble to be recycled. Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on. Metal objects: mainly including cans, cans, etc. Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc. Kitchen waste includes food waste, such as leftovers, bones, roots, leaves and peels, which are composted in situ by biotechnology. Comprehensive treatment and recycling can reduce pollution and save resources.
2) Matters needing attention when throwing garbage:
(1) Before the garbage is classified and put in, the paper should be stacked neatly as far as possible to avoid rubbing;
(2) After the products in the containers are cleaned and put into use, they should be used up as much as possible;
(3) The kitchen waste should be bagged and sealed.
(4) Glass articles should be handled with care to avoid damage.
⑤ Pay attention to cover the trash can after it is put into use, so as to avoid garbage polluting the surrounding environment and breeding mosquitoes and flies.
