How to evaluate 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:

First, reduce land occupation. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 50%.

Second, 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.

Third, 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.

Extended data:

In Chinese mainland, more than 90% of the available garbage is buried or burned. For example, there are more than 654.38+500 million tons of construction waste every year, and only a few thousand tons are recycled, and the premise of maximizing utilization is garbage classification. However, since 2000, Hangzhou has been a pilot city for garbage sorting, and then it has disappeared.

On March 25th, 20 10, the trial of garbage classification was started again, and the garbage was divided into harmful waste, recyclable garbage, kitchen garbage and other garbage, corresponding to red, blue, green and yellow trash cans respectively, and degradable kitchen garbage bags were provided free of charge. Garbage classification has covered 98% of the living quarters in Hangzhou, and 930,000 tons of garbage enter the recycling channel every year. However, the implementation situation is not optimistic, but trash cans of various colors occupy the limelight.
