At present, the color requirements for classified garbage bags vary from place to place. For example, Shanghai is black, red, coffee and blue, while parts of Guangdong Province are black, red, green and gray, some places are black, red, green and blue, and some places are black, red, gray and blue. Therefore, the color of classified garbage bags should be determined according to local policies and regulations.
Different colors of classified garbage bags represent different kinds of garbage. Generally speaking, garbage bags are classified into black, red, blue, green, brown, yellow and gray.
1, black: black bags generally store domestic garbage. For example, put some personal garbage, garbage bags in the bathroom, generally in black.
2. Red: represents harmful substances, and is sometimes marked with orange. Harmful substances include waste batteries, fluorescent tubes, paints, expired drugs, cosmetics and other substances that are not recyclable and have certain pollution hazards.
3. Blue: It means recyclable garbage, including valuable materials such as plastic, paper and metal, which will be included in the waste recycling system for resource recovery.
4. Green and brown: In the case of various plastic trash cans, green and brown represent kitchen waste, which can be used as fertilizer for plant nutrients, and can be decomposed and absorbed by natural microorganisms and plants after being buried, thus playing a role in recycling waste.
5. Gray: garbage other than harmful substances and recyclable substances, bricks, ceramics, muck and other wastes that are difficult to recycle are generally burned and buried.
6. Yellow: The yellow garbage bag is a bag of medical wastes, which is used to place medical infectious wastes, such as discarded blood bags, wastes stained with blood (hemostatic patches, cotton balls, etc.) and other wastes stained with blood.
What is garbage sorting?
Garbage classification generally refers to a series of activities that classify, store, put in and carry garbage according to certain regulations or standards, so as to turn it into public resources.
The purpose of garbage classification is to improve the resource value and economic value of garbage, reduce the amount of garbage treatment and the use of treatment equipment, reduce the treatment cost and reduce the consumption of land resources, which has social, economic and ecological benefits.
Garbage belongs to the public's private articles in the stage of classified storage. After being classified by the public, it becomes a regional public resource in the community where the public is located. Classified transportation to garbage collection points or transfer stations becomes a non-exclusive public resource. Judging from the classification methods of municipal solid waste at home and abroad, most of them are classified according to the composition and output of garbage, combined with the resource utilization and treatment methods of local garbage.
Significance of garbage classification
Garbage classification is the foundation of garbage terminal treatment facilities. The implementation of domestic waste classification can effectively improve the urban and rural environment and promote the recycling of resources. On the basis of scientific and reasonable classification of domestic waste, we will build a supporting system for domestic waste classification, establish a collection and transportation system that matches the classification of waste according to the classified varieties, establish a recovery system that is coordinated with the utilization of renewable resources, improve the terminal treatment facilities connected with waste classification, and ensure the interconnection of classified collection, transportation, recovery, utilization and treatment facilities. Only by doing a good job in supporting systems such as garbage sorting, garbage recycling and disposal can we operate more efficiently. Garbage classification is related to the construction of a resource-saving and environment-friendly society, which is conducive to further improving the quality of new urbanization and the level of ecological civilization construction in China.
The advantages of garbage sorting treatment are as follows:
Reduce land occupation
Reduce land occupation. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 50%.
Second, reduce environmental pollution.
Reduce environmental pollution. Waste batteries contain toxic substances such as metallic mercury, which will pose a serious threat to human beings. When waste plastics enter the soil, it will lead to crop yield reduction, so recycling can reduce these hazards.
Turn waste into treasure.
Turn waste into treasure. 1 ton of waste plastics can recover 600kg of unleaded gasoline and diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. Therefore, garbage recycling is both environmentally friendly and resource-saving.
