Why garbage sorting

Garbage classification is a reform of the traditional way of garbage collection and disposal, and a scientific management method for effective disposal of garbage。In the face of the increasing garbage production and the deterioration of the environmental situation, how to maximize the utilization of garbage resources, reduce the amount of garbage disposal, and improve the living environment through garbage classification and management is an urgent issue of common concern to all countries in the world.

The advantages of garbage sorting are as follows:

1. Reduce land erosion

Household waste. Some of these substances are not easily degradable, causing serious erosion of the land. Garbage classification, remove substances that can be degraded and are not easy to degrade, and reduce the amount of garbage by more than 60%.

2. Reduce pollution

China's garbage disposal mostly adopts sanitary landfills or even simple landfills, occupying tens of thousands of acres of land; And insects and flies fly around, sewage overflows, stench, and seriously pollutes the environment.

Waste plastics in the soil can lead to reduced crop yields; Waste plastic discarded is accidentally eaten by animals, resulting in accidents that lead to the death of animals from time to time. Therefore, the use of ** can also reduce harm.

3. Turn waste into treasure

China uses 4 billion plastic fast food boxes every year, instant noodles.

5 700 million bowls, billions of pairs of disposable chopsticks, these account for 8 15% of household waste. 1 ton of waste plastic can be used to recycle 600 kg of diesel. **1,500 tonnes of waste paper, exempt from the felling of trees used to produce 1,200 tonnes of paper. A ton of cans.

After melting, it can form a good aluminium block of one ton, and can be mined less than 20 tons of aluminum.

30% and 40% of domestic garbage can be utilized, and this small and profitable resource should be cherished. You can also use cans to make pencil cases, which is both environmentally friendly and resource-saving.

Garbage classification can better deal with garbage, some garbage can be used, and some may need to be incinerated, so it is easier to dispose of it separately!

Lao Huang carried two baskets of vegetables, walked four or five miles, and rushed to the market to sell. Two baskets of vegetables cost 150 pounds, Lao Huang picked it on his shoulders, tired but happy, humming a small tune along the way. When he arrived at the market, the vegetables were sold for nearly 200 yuan, and Lao Huang used the money to buy a bag of fertilizer, cut some meat, buy two bags of salt, and other bits and pieces.

The fertilizer weighs 50 pounds and is placed in a basket, just right. However, the problem is that the miscellaneous things on the other end weigh no more than ten pounds together. The weight of the two baskets is different, and when you pick it up, the light end is raised high.

Lao Huang could only move the flat burden on his shoulder as far back as possible, and at the same time, put his hand on the front of the flat burden, trying to press down. But still no. The difference in weight between the two baskets is too great and unbalanced to pick up at all.

conserve resources; No waste; Make the city more beautiful.

Reduce land occupation: Some substances in domestic waste are not easy to degrade, causing serious land erosion. Garbage classification, removal of substances that can be degraded, reducing the amount of garbage by more than 50.

Reduce environmental pollution: Waste batteries contain toxic substances such as metal mercury and cadmium, which cause serious harm to the human body; Waste plastics in the soil can lead to reduced crop yields; Discarded plastic waste has been eaten by animals, resulting in animal deaths. As a result, harm can be reduced.

Turning waste into treasure: China uses 4 billion plastic fast food boxes and 7.5 million instant noodles every year, with waste plastic accounting for 4-7 percent of household waste. One ton of plastic waste can be reprocessed with 600 kg of diesel.

**1,500 tonnes of waste paper can reduce the number of trees used to produce 1,200 tonnes of paper. A ton of tanks can be melted to form a ton of aluminum, and 20 tons of aluminum can be mined. 30 -40 percent of the production waste can be utilized, and this meager profit resource should be cherished.

You can also use cans to make pencil cases, which are both eco-friendly and resource-saving.

The above is from Delixin Intelligent Garbage Classification.

Because garbage classification is a scientific management method for effective disposal of garbage. Through classified delivery and collection, useful materials, such as paper, plastic, rubber, glass, bottles and cans, metals and waste household appliances, are separated from the garbage and put separately, re-used, and turned waste into treasure.

Garbage classification is a very meaningful thing, which can effectively save raw resources, improve environmental quality, drive green development, and lead a green life.

The cost of harmless garbage disposal is very high, depending on the treatment method, the cost of treating a ton of garbage is about 100 yuan to several hundred yuan. People consume a lot of resources, produce on a large scale, consume a lot of it, and produce a lot of garbage. The consequences will be dire.

From the perspective of the methods of domestic waste classification in foreign cities, they are generally classified according to the composition and amount of garbage, combined with the resource utilization and treatment methods of local garbage. For example, Germany is generally divided into paper, glass, metal and plastic.

Australia is generally divided into compostable garbage, which can be **garbage, and non-**garbage; Japan is generally divided into plastic bottles, which can be plastics, other plastics, resource waste, large garbage, combustible garbage, non-combustible garbage and hazardous garbage, etc.

The purpose of garbage classification is to improve the economic value and resource value, so as to reduce the amount of garbage disposal and the use of treatment equipment, reduce the cost of treatment, reduce the consumption of land resources, and have economic, social, ecological and other benefits. Garbage classification refers to a series of activities that are classified and stored, handled and put into public resources in accordance with certain regulations or standards. Garbage is a private property of the public at the stage of separate storage.

After the garbage is classified and put into the public, it becomes a regional public resource in the community or community where the public is located, and after the garbage is sorted and transported to the garbage concentration point or transfer station, it becomes a public resource without exclusion. Garbage classification is a basis for the operation of garbage terminal treatment facilities, and the classification of domestic waste is implemented, so as to effectively improve the urban and rural environment and promote the utilization of resources.

(1) A large amount of ammonia, sulfide and other harmful gases are released from garbage piled up in the open air, which seriously pollutes the atmosphere and the living environment of the city.

2) Serious pollution of water bodies. Garbage not only contains pathogenic microorganisms, but also produces a large number of acidic and alkaline organic pollutants in the process of stacking and decaying, and will dissolve the heavy metals in the garbage to form a three-in-one pollution source of organic matter, heavy metals and pathogenic microorganisms, and the leachate produced by rainwater will inevitably cause serious pollution of surface water and groundwater.

(3) Biological contamination. There are many pathogenic microorganisms in garbage, and garbage is often a breeding ground for mosquitoes, flies, cockroaches and rats, which inevitably endangers the health of the general public.

4) encroachment on a large amount of land. According to preliminary surveys, in 2003, 2 3 out of 668 cities in the country were surrounded by garbage patches. The total area of garbage storage in the country is 800,000 mu.

(5) More than 60% of the municipal solid waste is mainly generated by the secondary pollution of the organic waste of the residents of the community, that is to say, the continuous increase of the organic waste in the community is the source of the increasing municipal solid waste.

At the same time, garbage classification is an inevitable choice to achieve reduction, quality improvement and efficiency increase, and it is an important measure to improve the living environment, promote urban fine management and ensure sustainable development. Whether garbage classification can be achieved directly reflects the ecological literacy and civilization of a person or even a city. In this sense, today's garbage classification is the most fashionable, which plays a leading role in improving ecological civilization and social civilization.

Garbage classification is the basis for the operation of garbage terminal treatment facilities, and the implementation of domestic waste classification can effectively improve the urban and rural environment and promote the utilization of resources. On the basis of the scientific and reasonable classification of domestic waste, the construction of a supporting system for domestic waste classification should be carried out, and the collection and transportation system matched with garbage classification should be established according to the classification varieties, and the first system coordinated with the utilization of renewable resources should be established, and the terminal treatment facilities connected with garbage classification should be improved.

In order to ensure that the classified collection, transportation, utilization and processing facilities are connected with each other. Only by doing a good job in garbage classification, garbage ** and treatment and other supporting systems can operate more efficiently. Garbage classification and treatment is related to the construction of a resource-saving and environment-friendly society, and is conducive to the further improvement of the quality of China's new urbanization and the level of ecological civilization construction.

Precautions for garbage classification.

The school sets up two kinds of garbage bins in the same position on the side of the main road in public places, one is the garbage bin, the other is the garbage can not be the garbage can, the teachers and students of the school must put the garbage into the corresponding garbage bin according to the relevant requirements, and each class and department set up different types of garbage bins (cartons), which are classified and disposed of according to the requirements.

Waste paper and paper products, plastic beverage bottles and other plastics that can be sold; Cans, glass bottles and other usable waste that can be sold must be put into the dustbin.

Why garbage sorting

Why are we in a hurry to dispose of garbage?

Because we currently produce about 400 million tons of garbage every year, and there is an upward trend, if we do not speed up the disposal of garbage, the city will be surrounded by garbage, piles of garbage will pollute water quality, land and air, seriously affecting our health and environmental ecology. Therefore, we must find high-quality, reliable ways to dispose of waste to ensure everyone's health and sustainable social development.

So what does garbage sorting do to dispose of garbage?

1. Reduce land occupation: non-degradable substances can effectively reduce the land occupation by more than 60%.

2. Reduce environmental pollution: reduce the reduction of production caused by land damage and prevent accidental death of animals.

3. Reduce the demand for raw materials: Garbage can also be turned into important energy and resources such as electricity and diesel.

So what are the precautions before garbage sorting and delivery?

1. Hazardous garbage: harmful to human health and the environment, waste lamps, waste medicines, waste batteries, etc.

How to lose it? Waste batteries and waste lamps should be kept intact and put into a special collection instrument (pay attention to gentle handling). Waste drugs and medical appliances should be kept in their original packaging as much as possible, and put them in the expired drug ** box of the community service center formulated by the drug regulatory department.

2. Acceptable materials: recyclable waste paper, waste plastics, waste glass, scrap metal, etc.

How to lose it? Bottles and cans are poured into shapes, beverage cartons are pulled out of straws, and cans are flattened and compacted.

3. Wet garbage: corrosive biomass, leftovers, expired food, melon peel and fruit pits.

How to lose it? The packaging is removed and put into the ** material or dry garbage, and the residue is put into the wet garbage.

4. Dry garbage: other garbage in addition to the above, lunch boxes, napkins, wet wipes, plastic bags, makeup brushes.

How to lose it? Drain as much water as possible, and dispose of hard-to-identify categories into the garbage.

1. It is also the most obvious point to protect the environment, among the garbage we produce daily, such as some harmful garbage, which needs to be specially treated, if it is dumped directly in the soil, it will cause irreversible damage to the land, after all, there is only one earth.

2. Make the soil fertile, mainly those perishable wet garbage, after many times of processing, produce the organic fertilizer necessary for the soil, which can be said to be reused.

3. Put the best things in a garbage can, which can reduce the time for sanitation workers to pick, and at the same time allow them to have more income and turn waste into treasure.

4. Lucid waters and lush mountains are invaluable assets, and after a long time, garbage classification can improve the ecological environment where people live, and the blue sky and white clouds are no longer a dream.

5. In terms of garbage resource reuse, energy is conserved, therefore, a lot of energy in garbage is not fully utilized.

6. It is good for physical health, the implementation of garbage classification, the ultimate beneficiary must be us human beings, and the perishable, harmful and other different garbage is placed separately, which is beneficial to health.
