What are the garbage classification signs and what are their uses?

The colors and labels of classified garbage bins are as follows:

1. Red

Red stands for harmful waste. Harmful substances include waste batteries, fluorescent tubes, paints, expired drugs, cosmetics and other substances that are not recyclable and have certain pollution hazards.

2. Green

Green represents kitchen waste. Kitchen waste can be used as fertilizer for plant nutrients, and can be decomposed and absorbed by natural microorganisms and plants after being buried in the soil, thus playing a role in recycling waste.

3. Blue

Blue represents recyclable garbage, including valuable substances such as plastics, paper and metals, which will be incorporated into the waste recycling system for resource recycling.

4. Gray

Except for harmful substances and recyclable substances, garbage, bricks, ceramics, muck and other wastes that are difficult to recycle are generally incinerated and buried.

the purpose of garbage classification is to improve the resource value and economic value of garbage, strive to make the best use of it, 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 private property of the public at the stage of classified storage. After being classified by the public, it becomes a regional public resource of the community where the public is located, and after being classified and transported to the garbage concentration point or transfer station, it becomes a public resource without exclusion. Judging from the classification methods of domestic garbage in cities 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.
