After the implementation of waste separation in Shanghai and other places, different treatments are required depending on the type of waste.



Waste plastic can be used to refine unleaded gasoline and diesel fuel; recycled paper can be used to avoid cutting down forests used to produce paper; and cans can be melted down to make good aluminum blocks, saving aluminum mining resources.

The garbage is collected through classification, which makes it easy to classify and dispose of different types of garbage. Not only to improve the level of utilization of garbage resources, but also to reduce the amount of garbage disposal. The classification of household garbage has the following benefits:

1) Reduce the occupation of land; the classification of garbage, the removal of materials that can be recycled and are not easily degraded, reducing the amount of garbage by more than 50%.

2) Reduce environmental pollution: discarded batteries, etc. contain toxic substances such as metallic mercury, which can cause serious harm to human beings, and waste plastics in the soil can lead to crop yield reduction, so recycling can reduce the harm.

3) Waste into treasure: China's annual use of plastic fast food containers up to 3 billion, instant noodle bowls 500 million -600 million, waste plastic accounted for 3% -7% of domestic waste; 1 ton of waste plastic can be back to refining 600 kilograms of unleaded gasoline and diesel fuel; recycling 1,500 tons of waste paper can be exempted from cutting down the forest used to produce 1,200 tons of paper ; one ton of cans can be melted to form one ton of very good aluminum block. Therefore, garbage recycling is both environmentally friendly and resource-saving.

The benefits of segregating garbage are obvious. Garbage is sorted and sent to factories instead of landfills, saving land, avoiding pollution from landfills or incineration, and turning waste into treasure. This battle between people and garbage has turned garbage from an enemy into a friend.

Principles of Garbage Classification:

1, Divide and Use: The purpose of classification is to divert waste for disposal, to utilize the existing production and manufacturing capacity, to recycle and utilize recycled products, including material utilization and energy utilization, and to dispose of useless garbage temporarily unavailable in landfills.

2, adapted to local conditions: localities, districts, communities (districts), neighborhoods geography, level of economic development, the ability of enterprises to recycle and utilize waste, the source of the residents, living habits, economic and psychological affordability, etc. vary.

3, consciously self-governance : communities and residents, including enterprises and institutions, gradually develop "reduction, recycling, self-consciousness, self-governance" of the norms of behavior, innovation of garbage classification and treatment mode, to become the main force of garbage reduction, classification, recycling and utilization.

4, Subsidies for emission reductions, penalties for over-emission: the development of units and residents of garbage emission standards, below this emission standard to give subsidies; more than this emission standard will be punished. Emission reduction the more subsidies the more, the more over-emission the heavier the penalty, so as to improve the unit and residents to implement the source of reduction and emission control enthusiasm.

5, bundled services, focusing on performance: in the residents have not been voluntary and conscious action and residential (village) committees and the government's resources are insufficient to promote categorization of emissions need to be involved in the property management companies and other enterprises. However, it is difficult to make a profit just by undertaking sorting and discharging, and enterprises are unlikely to intervene, while the implementation of bundled services can solve this problem. The promotion of classified discharge services and garbage collection, wet and dry waste disposal business bundled, can promote the capitalization of waste classification, to ensure that the enterprise reasonable profit.
