Investigation Report on Garbage Sorting
When a situation or event needs to be figured out, we need to carry out investigative work and present the results obtained in an investigation report. What do you need to pay attention to when writing an investigation report? The following is my carefully organized investigation report on garbage classification, welcome to share.
Trash classification investigation report 1
With the rapid changes in technology, the modernization of the city to speed up the process, our lives have become colorful and colorful. But with these advances comes not only the convenience of people's lives, and with it the deterioration of the city's living environment. Environmental issues have been one of the major social problems, the classification of waste disposal is particularly important, which is directly related to the degree of environmental damage to the living waste. Therefore, a good separation of garbage disposal will be an important measure to alleviate the environmental problems. In order to better deal with domestic garbage, to create a beautiful and comfortable living environment, I and my several friends of my city's domestic garbage disposal situation to carry out some research, and combined with the actual talk about my understanding and suggestions.
First, the classification of garbage
Garbage is mainly divided into: construction waste, medical waste, industrial waste, sewage sludge, and domestic waste. Construction waste can be recycled by the construction unit for the corresponding processing; medical waste from hospitals and other health units responsible for the relevant processing; industrial waste disposal is mainly business units within the task; and wastewater sludge is also a wastewater treatment plant for the corresponding processing. These garbage generation is more centralized, classification and processing is also more convenient.
Second, the benefits of garbage classification
Garbage classification and collection can reduce the amount of garbage disposal and processing equipment, reduce the cost of processing, reduce the consumption of land resources, with social, economic and ecological benefits.
The advantages of garbage classification are as follows:
Reducing land occupation. Some substances in domestic garbage are not easy to be degraded, which causes serious erosion of land. By separating garbage and removing those that can be recycled but are not easily degraded, the amount of garbage can be reduced by more than 60%.
Waste plastics in the soil will lead to crop yield reduction; discarded waste plastics accidentally eaten by animals will lead to animal death. Recycling 1,500 tons of waste paper, can be exempted from cutting down the forest for the production of 1,200 tons of paper. 1 ton of cans can be melted into 1 ton of very good aluminum block, can be less 20 tons of aluminum ore. 30% to 40% of the production waste can be recycled and should be treasured as a small and profitable resource. We can also use cans to make pencil cases, both environmental protection and resource saving.
Characteristics of household garbage
Compared with other garbage, the situation of household garbage is much more complicated, and there are mainly the following performances:
1. The source of the widely scattered, diverse and complex. The so-called domestic waste, as the name suggests, as long as there are people living in the place will produce domestic waste. We live in different places, even in the same city, but also live in the same corner of the city. It takes human and material resources to gather it. Moreover, modern life is complex and diverse, so all kinds of household garbage are available, for example, plastic bags, tissue paper, chewing gum, used electronics and so on. It involves inorganic, organic, easily degradable, difficult to degrade, toxic and harmful. In this way, the source of domestic waste is extensive, scattered, complex, not at all.
2. There is a general lack of general knowledge about garbage classification and the habit of garbage classification. The knowledge of related garbage classification is vague, so that people do not understand the concept of garbage classification well. For example, the current classification of garbage is mainly divided into: recyclable, non-recyclable. This classification is not clear enough. People only have knowledge of certain more common recyclable garbage, but not so clear about the uncommon recyclable garbage. In my opinion, the classification of non-recyclable waste is too general, like plastic bags and melon shells such as household waste, can be said to be non-recyclable, but plastic bags are non-degradable, while the melon shells can be degraded, the two are not the same treatment.
3. Part of the household waste disposal is improper, the lack of professional waste disposal technology. This situation from the beginning of the small and medium-sized cities, due to the small size of the city, there is no corresponding garbage disposal station. A large amount of domestic garbage is piled up on the outskirts of the city, and it is not uncommon to see it burned on the spot. This has resulted in the recontamination of household waste, incineration of dust and toxic and harmful gases pollute the atmosphere, directly affecting the quality of life of residents.
4. The hardware facilities in residential neighborhoods are uneven, bringing great obstacles to the front-end of waste classification and disposal. Some residential neighborhoods are set up with classified waste bins, while some neighborhoods are not classified waste garbage cans. The result is that the front end of the garbage generation is not handled well, the garbage is not classified at all, and the later processing will also be impossible to talk about.
5. The middle end of the waste classification process is unreasonable. The middle end of the garbage classification process refers to the further classification of garbage at the sanitation waste transfer station, which is a key step in determining the back-end processing. The garbage transfer station further classifies the garbage, and then the classified garbage is treated differently. If the sanitation workers do not pay enough attention to the separation of garbage, and mix the garbage that the residents have already separated together, it will be a big no-no. I say this because there are really many sanitation workers who do this.
6. The terminal treatment of household waste is not scientific enough. Now there are a lot of domestic waste disposal methods, some are reasonable, some are not very reasonable. For example, the open burning of landfills is very unscientific, which wastes the potential utilization value of garbage and pollutes the environment at the same time, which is really not desirable. Similarly, the landfill method is not very reasonable either. Wasting labor to fill up the landfill is a waste of effort. On the contrary, if the waste is used to generate electricity, or if the waste is divided into different categories and then utilized, it is the optimal choice.
Four, the classification of household garbage disposal methods
Nowadays, China's household garbage can generally be divided into four categories: recyclable garbage, food waste, hazardous waste and other garbage. Currently commonly used waste disposal methods are: comprehensive utilization, sanitary landfill, incineration power generation, composting, resource return.
Recyclable garbage mainly consists of waste paper, plastic, glass, metal and fabric. Waste paper mainly includes newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cardboard boxes, etc., but note that paper towels and toilet paper are too water-soluble to be recycled.
Plastic mainly includes a variety of plastic bags, plastic packaging, disposable plastic lunch boxes and cutlery, toothbrushes, cups, mineral water bottles, toothpaste skins and so on.
Glass mainly includes a variety of glass bottles, broken glass pieces, mirrors, light bulbs, thermos flasks and so on. Metal objects mainly include cans, can boxes and so on. Fabrics mainly include discarded clothes, tablecloths, washcloths, schoolbags, shoes and so on.
Food waste includes leftovers, bones, vegetable roots and leaves, fruit peels and other food wastes, which can be composted by biotechnology in-situ treatment, and can produce about 0.3 tons of organic fertilizer per ton.
Hazardous waste includes waste batteries, waste fluorescent tubes, waste silver thermometers, expired medicines, etc., which require special treatment.
Other garbage includes masonry ceramics, slag, toilet paper, paper towels and other hard-to-recycle waste in addition to the above categories of garbage, taking sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
V. Important Initiatives in Some Cities
The key to real waste minimization and resource utilization is front-end classification. If the government budget can take into account the "front-end" needs, provide special funds to stimulate the public to participate in the enthusiasm of waste classification, the classification guidance volunteers, engaged in the "second sorting" of cleaning workers to give subsidies, increase the sanitation sub-loading, sub-transportation equipment investment, then the The effect of the implementation of garbage classification will be more obvious.
Garbage classification survey report 2Garbage is a long-standing problem, as long as people exist, garbage is accompanied by the left and right, so how do we do with the garbage and peace **** with it? Faced with the encirclement of garbage, should we take effective means to control it, so as to utilize it for the benefit of our human beings? At present, garbage classification is a more ideal method. Garbage classification can effectively reduce the amount of garbage and increase the utilization value of garbage. Through the investigation, we obtain the current situation of garbage classification at home and abroad, and understand the reasons that hinder the classification of garbage, put forward some feasible suggestions, and also gain some insights from it. The Importance of Garbage Classification
(A) Knowledge of Municipal Garbage
Municipal garbage has become one of the world's urban problems, and with the rapid growth of the urban population in our country, this problem is particularly serious and urgent. In fact, municipal waste is a resource and should not be a problem. Japan's garbage classification is extremely strict, so that the world attention, garbage is effectively utilized, we in China in this regard just started, there have been studies on urban garbage classification, in some big cities, there have been many areas to carry out pilot work, we need more people to pay attention to this issue, so that most of the people understand the classification of garbage, and implementation of the action, in this case, I carried out the survey.
Domestic waste in China can generally be divided into four main categories: recyclable waste, food waste, hazardous waste, and other waste. Currently the commonly used methods of waste disposal are mainly comprehensive utilization, sanitary landfill, incineration and composting.
1, recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth five categories. Waste paper: mainly including newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cardboard boxes, etc., but note that paper towels and toilet paper due to water solubility is too strong not to be recycled. Plastic: mainly including various plastic bags, plastic packaging, disposable plastic lunch boxes and cutlery, toothbrushes, cups, mineral water bottles and so on. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos flasks, etc. Metal objects: mainly cans, can boxes, toothpaste skins, etc. Fabrics: mainly including discarded clothes, tablecloths, washcloths, schoolbags, shoes, etc. Recycling through comprehensive treatment can reduce pollution and save resources. For example, each recycled 1 ton of waste paper can make good paper 850 kilograms, saving 300 kilograms of wood, than the same amount of production to reduce pollution by 74%; each recycled 1 ton of plastic beverage bottles can be 0.7 tons of secondary raw materials; each recycled 1 ton of scrap iron and steel can be refined 0.9 tons of steel, smelting with ore to save 47% of the cost of smelting to reduce air pollution by 75%, reducing 97% of the water pollution and solid waste.
2, food waste, including leftovers, bones, vegetable roots and leaves, peels and other food waste, composted by biotechnology in situ treatment, each ton can produce 0.3 tons of organic fertilizer.
3. Hazardous waste includes waste batteries, waste fluorescent tubes, waste silver thermometers, expired medicines, etc., which require special safety treatment.
4, other waste including in addition to the above categories of waste, brick ceramics, slag, toilet paper, paper towels and other difficult to recycle waste, to take sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
(b) The advantages of waste classification and disposal are as follows:
1, to reduce the occupation of land: some of the substances in the domestic waste is not easy to degrade, so that the land is seriously eroded. Garbage classification, remove can be recycled, not easy to degrade the material, reduce the amount of garbage up to 50% or more.
2, reduce environmental pollution: discarded batteries contain metal mercury, cadmium and other toxic 'substances, will produce serious harm to human beings, waste plastics in the soil will lead to crop yield reduction, discarded waste plastics accidentally eaten by animals, resulting in the death of the animal accidents occur from time to time. Therefore recycling can reduce the harm.
3, waste to treasure: China's annual use of plastic fast food containers up to 4 billion, 5.7 billion instant noodle bowls, waste plastic accounted for 47% of domestic waste. 1 ton of waste plastic can be back to refining 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 down to form one ton of very good aluminum blocks, which can reduce the mining of 20 tons of aluminum ore. 30% and 40% of the production waste can be recycled and should be treasured as a small and profitable resource. We can also use the cans to make pen boxes, both environmental protection, but also save resources.
According to the China Environmental Protection Industry Association of municipal waste disposal committee information shows that at present, China's municipal waste disposal in the landfill method of waste disposal accounted for 70%, composting accounted for 20%, incineration accounted for 5%, and the other (including open piles, recycling) accounted for 5%.
But what is the current status of garbage classification in Yancheng area? Most people throw garbage away without classification, mixing recyclable, non-recyclable and toxic ones together. Then, what are the reasons for this status quo? According to the survey, the reasons are as follows:
1, our country about this aspect of the supervision is not enough, the lack of legal protection, the relevant environmental protection department did not give enough attention. Although there are a lot of classified garbage cans on the street, but it is just like a sham, people do not have the consciousness of consciously classified garbage. The government also did not come forward to emphasize the need for waste classification and disposal, the financial investment in waste classification is not enough, and the relevant waste follow-up facilities have not kept up.
2, the public's awareness of garbage classification is weak, the lack of knowledge of garbage classification. Some people think that garbage is the same whether it is classified or not, as long as it is not thrown away, classification is not only a waste of time, but also a waste of energy. These are wrong understandings. It is understood that the garbage we throw out every day is usually sent to landfills first and then to landfill. Landfills are expensive, and it costs about $200 to $300 to dispose of a ton of garbage. Nowadays, people consume a lot of resources, produce on a large scale, consume a lot, and produce a lot of waste. How much land is going to be turned into landfills by this huge amount of waste? And where will our future generations live? Therefore, landfill is a waste of resources. The classification of waste is the classification of waste at the source, the waste can be used to reclassify, so as to increase the utilization rate of resources, so that not only save the land, but also to avoid the landfill fire incineration of pollution.
(C) how to change the status quo
In this survey, the survey respondents from elementary school students to the elderly in their 60s, civil servants, housewives and retirees. During the survey, the vast majority of the public expressed a high degree of concern and attention to the issue of household waste, but lack of understanding of the benefits of waste recycling, and feel that the classification of household waste is more troublesome.
The survey also shows that the general public has realized that plastic bags and disposable fast food containers have become a major problem in garbage disposal, but a large proportion of people still use them frequently. For knowing where the garbage is eventually collected, most people can name several ways to dispose of garbage, the public's awareness of garbage disposal needs to be enhanced. The crux: residents have not yet developed the habit of classification.
According to the Municipal Urban Management Bureau of domestic landfill management center staff said that the community residents have not yet developed a good habit of waste classification. Although in some districts and roads placed in different colors of the classification of collection boxes, but many people do not know what garbage can be recycled, there are some residents wrongly believe that they have to pay the health fee, garbage classification and disposal should be a matter of sanitation department, in addition, littering people are also a lot of people.
It is understood that, at present, the coastal community of Yancheng City Dayang Street has set up a different color classification of garbage cans, and posted signs. But the classification of garbage has not become a conscious action of the residents, the garbage cans put a few years, basically not be distinguished from the use. Most of the daily garbage classification is done by some sanitation workers and urban scavengers, who collect a small amount of recyclable parts of garbage.
Looking forward to: the early realization of the classification of domestic waste
According to experts, the classification of garbage is not a simple separation of issues, should be a classification system, by the classification of garbage collection, classification and compression, classification and transportation, classification and utilization of a series of links **** with the same composition, and even some of the links have a staggered and overlapping relationship.
In the face of the people's lack of awareness of waste classification, our first task is to start from the aspect of raising awareness. Therefore, we must increase publicity efforts to guide people to implement waste classification. We can do this by organizing speeches, exhibitions, exchanges and other forms of activities to expand the impact of television, the Internet, newspapers, magazines, books and so on to let people get the relevant information, such as the preparation of a practical "garbage classification manual", easy to understand to the residents of all kinds of waste disposal methods, classification principles, so that the classification of garbage deep into the lives of each resident.
In the current situation of garbage classification is not popular, we should have the conditions in the community to set up the classification of garbage bins, to carry out pilot work, and arrange for the relevant personnel to carry out appropriate tips to guide and help residents gradually develop the habit of consciously classifying garbage. On the basis of the pilot work to achieve certain results, in accordance with the principle of "gradual and orderly, highlighting the effectiveness of", to promote the whole region, and constantly grow the scope of use of waste separation bins. In order to stimulate the enthusiasm of residents to carry out waste classification, the government environmental protection departments should provide residents with as much convenience as possible. For example, the configuration of a clearly marked special apparatus, regular door-to-door recovery of toxic and hazardous waste, to the residents of the classification of garbage bags, etc..
(4) Summary
Proper disposal of household garbage, whether from the use of resources, or from the point of view of environmental protection, is of great significance. It takes a long process for the general community to develop a good habit of classifying and disposing of household garbage. After this investigation, I learned a lot about garbage classification, and at the same time, I also experienced a day that I could not feel in school. Maybe not everyone has a strong sense of environmental protection, maybe every time you ask a question will be in a hurry to catch up with the refusal of the people, but under the hot summer sun, is still burning is my enthusiasm, I think, this is enough, because we have worked hard, in the process of environmental protection awareness passed out.
Garbage classification investigation report 3First, the problem:
With the social and economic development, environmental pollution is becoming increasingly serious, urban garbage can be seen everywhere. According to relevant information: in the past 10 years, China's urban garbage average annual growth rate. In the country's 400 large and medium-sized cities, 2/3 of the city has been in the garbage surrounded. Our country has reached 6 billion tons of garbage over the years, encroaching on more than 500 million square meters of land. At present, China is still producing new garbage at a rate of hundreds of millions of tons per year. How is this garbage produced and how is it disposed of? These questions have aroused great research interest.
A survey of the current situation:
Early in the morning, both sides of the street is everywhere visible is the garbage, some wrapped in plastic bags, some just randomly disposed of on the ground, and some placed in the trash can.
Passing by the hospital, I saw some expired medicines, discarded mercury thermometers and some bottles of medicine, infusion sets were discarded in the corner of the hospital, the garbage emits a pungent smell, so I dare not approach.
In one corner of the factory, discarded batteries, old machines, circuit boards, and broken glass and boards are piled up. Batteries have been broken, leaking out the liquid inside. Waste batteries are known as "miniature killers", we can imagine that these waste batteries seeped into the soil, will cause much harm to the land.
Vegetable markets, discarded fish and vegetables arbitrarily piled up in the road, flies buzzing, such a scene makes me feel surprised, can not buy out of the food are so randomly discarded?
A sanitation worker told me that these piles of garbage have to be sent to a certain place for landfill or incineration.
The Harm of Garbage:
The potential harm of disposing of garbage randomly is huge. How much land does it take to turn so much garbage into a landfill? In the process of incineration, how many toxic gases will be produced, jeopardizing people's health? We are constantly turning our limited resources into garbage, and burying or burning them, and in the long run, where will our future generations go to find the energy they need?
Three, the classification of garbage disposal:
Is it true that we can do nothing about the pollution of garbage? No. According to our research, garbage can generally be divided into four categories: recyclable garbage, food waste, hazardous waste and other garbage.
Recyclable garbage is sent directly to the relevant factory for reprocessing and waste utilization. For example: 1 ton of waste paper can be recycled 800 kilograms of good paper; recycled batteries can be extracted rare metals zinc, copper and manganese dioxide; recycled waste plastics can be smelted back to fuel.
Kitchen waste, such as leftovers, lettuce, eggshells, fruit peel, vegetable gangs and leaves, etc., can be piled up, so that the waste fibers and organic matter decay, into fertilizer to improve the soil.
Harmful garbage, such as waste fluorescent tubes, expired medicines, etc., can be concentrated and incinerated to minimize the hazards of garbage.
Other garbage, such as ceramics and slag, which are difficult to recycle and are not harmful to the environment, can be effectively landfilled to minimize the pollution of groundwater, soil and air.
Four, our thinking:
Relevant statistics show that: China's annual value of waste that can be used but not utilized amounted to 25 billion yuan, about 3 million tons of scrap steel, 6 million tons of waste paper has not been recycled. The recovery rate of waste plastics is less than 3%, and the recovery rate of rubber is 31%. Only more than 6 billion waste dry batteries thrown away each year contain more than 70,000 tons of zinc, 100,000 tons of manganese dioxide. Classification and recycling of waste is valuable:
Waste paper:
Recycling 1 ton of waste paper can be recycled out of 800 kilograms of good paper, you can save 17 trees, saving 3 cubic meters of landfill space, less soda ash 240 kilograms, reduce the pollution emissions of papermaking by 75%, saving the paper making energy consumption and each piece of paper can be recycled at least twice.
Waste plastic:
Plastic from the earth's non-renewable resources - oil, recycling waste plastic is to save oil. All waste plastics, waste lunch boxes, food bags, woven bags, flexible packaging boxes, etc., the use of waste plastics reduced to gasoline, diesel technology can be refined back to fuel; from 1 ton of waste plastics can produce liters of unleaded gasoline or diesel.
Waste glass:
Waste glass recycling, not only can save natural resources, but also reduce energy consumption by about 32%, reduce air pollution by 20% and 50% of water pollution. 1 ton of waste glass back to the furnace than the use of new raw materials to save 20% of the cost of production. The benefits of recycling one ton of waste glass to the environment and resources are: you can save 720 kg of quartz sand, 250 kg of soda ash, 60 kg of feldspar powder, 10 tons of coal, electricity 400 degrees.
Waste aluminum cans:
Waste cans can be 100% dissolved and recycled countless times into new cans, but also, can be made into parts of cars and planes, etc., and even furniture. Recycling aluminum cans saves 95% of the energy needed to make new cans and reduces air pollution by 95%. Throwing away an aluminum can is the same as wasting half an aluminum can of oil.
Organic matter:
More than 40% of the garbage we still get out of our house every day is kitchen garbage such as fruit peels, egg shells, vegetable leaves, leftovers, and so on, which can be processed into organic fertilizers or feeds by composting and fermentation methods.
Waste batteries:
Mercury and cadmium contained in waste batteries are highly polluting toxic heavy metals, but recycled batteries can extract rare metals such as zinc, copper and manganese dioxide.
V. Our Suggestions:
1, through the publicity, so that the people understand the importance of garbage classification;
2, in the residential areas, vegetable markets, hospitals, factories and other places to set up the classification of garbage bins, so that it is easy for sanitation workers to classify all kinds of garbage.
Garbage is a public nuisance, but as long as we use the method of garbage classification to deal with, it is completely possible to turn garbage from an enemy to a friend
2, about the ceramic investigation report
Today, we went to the Zhejiang Museum to make a survey about ceramics. We were divided into two groups, a and b. Group a investigated pottery in the exhibition hall on the first floor, and group b investigated porcelain on the second floor. I participated in the a group.
By watching the introduction and listening to the explanation, I know the pottery and porcelain is not the same thing. Pottery appeared earlier than porcelain, pottery is made of smaller particles of earth fired into a vessel. In ancient times, pottery was mainly used for rituals and burials.
Porcelain appeared in the Eastern Han Dynasty, which is a smooth glaze on the surface of pottery. Depending on the color of the glaze, porcelain is divided into many types, including celadon and white porcelain ...... The famous celadon, due to the presence of iron in the glaze, takes on a jasper-like green color.
In ancient times, pottery and porcelain were used for rituals, passing of titles and other activities. And in modern times, ceramics turned into household items, which helped people to pan rice, serve rice and became indispensable items for family life.
Pottery and porcelain are indispensable both in ancient and modern times, and they are the crystallization of the wisdom of the ancient Chinese working people.
Garbage classification investigation report 4With the improvement of our lives and social progress, we produce a large amount of garbage has a new way to deal with the kitchen leaves, kernels, leftovers and other garbage can be processed to become fertilizer, or the formation of methane can be used for combustion; we use the broken TV, refrigerator, car and other metal-containing garbage, they can be reused after special treatment, saving resources, green environmental protection; we use bad TV, refrigerators, cars and other metal-containing waste, they can be reused after special treatment. We use the broken TV, refrigerator, car and other metal waste, they can be reused after special treatment, saving resources, green environmental protection; we produce plastic waste can also be processed to form new plastic products. This is garbage classification, a term that is already very common in foreign countries, but not very easy to implement in China. In foreign countries, waste classification is divided into very detailed food waste, hazardous waste, etc., in the country, I have seen that there are recyclable and non-recyclable two kinds of only, the same is the classification of garbage, why is the gap between the different countries is so big? The problem is that there is a big difference between different countries.
We looked around different neighborhoods and found that many of them did not have waste separation, so we started to interview a sample of residents in the neighborhoods. After briefly asking a few questions, such as: do you carry out garbage classification and disposal? What do you think about garbage classification? Do you know what is the function of garbage classification? After some inquiries and surveys, we found that almost all of the residents did not separate their garbage because it was troublesome and even if they wanted to separate their garbage, there was no place to do so in the neighborhood. Most of the residents think that garbage sorting is not very useful, and that only a small amount of garbage can be recycled. They think that garbage sorting is not only troublesome, but also not very useful, so they do not support it very much. After analyzing the results of the survey, we found that the implementation of waste classification is not so simple.
In order to better carry out the classification of garbage, I have the following suggestions: First, to provide relevant guidance, so that people can set up the concept of garbage classification, so that people know the classification of each kind of garbage, so that people can clearly understand the role and significance of garbage classification. Secondly, the relevant environmental authorities should set up more complete facilities for waste separation so that residents can have a place to do so. Thirdly, the way of garbage disposal should be improved. After garbage classification, different kinds of garbage can be disposed of in different ways, and it should not be incinerated or buried for the sake of simplicity and quickness, but to discover the economic benefits of garbage. Fourthly, short-term household collection should be carried out, and the collected garbage should be separated and recycled regularly. Fifthly, expand the scope of garbage classification, not just confine it to a certain place. Sixth, set up regulations on garbage classification, and crack down on the phenomenon of arbitrary disposal of garbage causing serious environmental damage.
Classification of garbage can reduce environmental pollution, turn waste into treasure, save energy, reduce the work of sanitation staff, etc., which has an important role in our future healthy development.
