Kneeling what is the significance and methods of campus waste classification

One, the significance

1, reduce the occupation of land

Some of the substances in the domestic garbage are not easy to be degraded, so that the land is seriously eroded. Garbage classification, remove the recyclable, not easy to degrade the material, reduce the amount of garbage up to 60% or more.

2, reduce pollution

Currently, China's garbage disposal mostly adopts sanitary landfill or even simple landfill, occupying tens of thousands of acres of land; and insects and flies fly, sewage overflows, the stench of the sky, seriously polluting the environment.

The waste plastics in the soil will lead to crop yield reduction; discarded waste plastics by the animals accidentally eat, resulting in animal deaths occur from time to time. Therefore recycling can also reduce the harm.

3, waste into treasure

China's annual use of plastic fast-food containers amounted to 4 billion, instant noodle bowls 500-700 million, billions of pairs of disposable chopsticks, which accounted for 8-15% of the household garbage. 1 ton of waste plastic can be smelted back to the 600 kilograms of diesel fuel. Recycling 1,500 tons of waste paper can avoid cutting down forests used to produce 1,200 tons of paper. One ton of cans can be melted to form a ton of very good aluminum blocks, which can be mined 20 tons less aluminum ore.

Two, the method

1, establish the concept of waste classification.

Widely carry out the publicity, education and advocacy of garbage classification to make students establish the environmental protection consciousness of garbage classification, elucidate the serious harm caused by garbage to campus life, publicize the significance of garbage classification, and call on students to actively participate in garbage classification. At the same time, students are taught the knowledge of garbage classification, so that students will gradually become conscious and habitual behavior of garbage classification.

2, remodeling or additional facilities for garbage classification and recycling.

You can divide a garbage can into several compartments or establish several independent garbage cans. Garbage classification should be gradually refined. The more detailed and refined the classification of garbage, the more conducive to recycling. Different color bins can be used to recycle glass, paper, plastic and metal packaging waste, plant waste, household waste, batteries, light bulbs and other special waste.

The category of recycling and brief instructions for use must be indicated on the trash can to guide consumers. Trash cans can also be a vehicle for corporate advertising, and companies can bear the cost of producing them.

3. Improve the form of garbage storage and transportation.

Some of the large size of the garbage, should be compressed for storage and transportation. Particular attention should be paid to the Bureau of Sanitation's garbage recycling trucks to carry out segregated renovation, classification of loaded garbage. Give full play to the role of the original garbage recycling channels, resale of recyclable garbage to enterprises.

In addition, the establishment of specialized recycling teams for the downstream industries of garbage, direct recycling by manufacturers, the realization of multi-channel recycling, and the introduction of a competitive mechanism of price and service, as a way to improve the quality of their services and the recycling rate of garbage.
