Investigation report on garbage classification of college students

I. Ask questions:

1. The mass production of garbage and its harm to human life. With the improvement of people's living standards and the growth of population, more and more waste products are abandoned to nature by human beings, and nature has been scarred. Untreated factory waste, waste residue and domestic garbage are simply piled up in the open air, occupying land and destroying the landscape. Moreover, the harmful components in the garbage drift with the wind and enter the soil, rivers or underground water sources after the rain, which brings serious pollution to the urban environment and seriously endangers human life and health.

2. Ignorance of garbage disposal. How to deal with the classification of garbage has become one of the problems to be solved urgently.

Two. The purpose and significance of the investigation

The purpose of this study is to understand the correct methods of garbage disposal, enhance students' awareness of environmental protection and promote garbage classification.

Three. investigation method

1. Interview. That is, through interviews with people around us, we can understand their understanding and practice of garbage classification, so as to further understand people's practice of garbage classification in real life.

2. Literature method. Through the query of library and network literature, we can understand the scientific garbage classification and treatment methods, and provide theoretical support for this study.

3. Observation method. By observing people in different streets, we can know whether everyone can do garbage sorting.

Four. The content of the investigation

The main contents of this survey are whether the garbage sorting treatment has been implemented, whether there is littering on the road, trash cans and cleaning in streets and communities.

Verb (abbreviation of verb) Literature Review

Garbage is solid waste produced in human daily life and production. Because of its large emissions and complex components, it brings difficulties to treatment and utilization. If it cannot be handled in time or improperly, it will pollute the environment and affect environmental sanitation. Garbage disposal is to quickly remove garbage, treat it harmlessly, and finally make rational use of it. At present, the widely used garbage disposal methods include sanitary landfill, high-temperature composting and incineration. The purpose of garbage disposal is harmlessness, recycling and reduction.

The exploitation and utilization of natural resources by human beings are expanding in scale and intensity. The speed of consuming resources has also greatly accelerated. On the one hand, it has brought civilization to society and improved people's quality of life, on the other hand, it also means accelerating the growth of garbage, which is one of the important reasons for environmental pollution. If you let yourself go. Neglect of management and governance will cause public hazards, destroy the ecological environment and endanger people's health. Mainly in the following aspects:

1. Garbage piling not only occupies land, but also pollutes soil and crops. Dumping, scattering or stacking domestic garbage at will.

2. Garbage pollutes groundwater or enters surface water through rainwater infiltration, resulting in water pollution. 80% of the epidemic is spread because of this.

3. Garbage will spontaneously ignite and explode. Due to the fermentation of the piled garbage, methane gas exploded.

4. White pollution such as plastic bags, plastic cups and foamed plastic products is not easy to decompose.

5. Weihai hazardous waste directly or indirectly affects human health.

6. The phenomenon of littering, dumping, spitting, dumping and pasting is serious, and dirt such as peel scraps, snack bags, betel nut residue and sputum marks can be seen everywhere;

7. littering, old furniture occupying the sidewalk;

8. After playing cards and cards are shredded? Goddess scattered flowers? ;

9.？ Psoriasis? Advertising? Certificate? The telephone is pervasive, and clean and bright places are drilled, which is repeatedly banned and seriously affects the image of the city.

10. The pavement is seriously polluted by waste soil and abandoned building materials.

In modern cities, garbage, as the product of urban metabolism, was once a burden of urban development, and many cities in the world were besieged by garbage. Nowadays, garbage is considered as the most potential and inexhaustible? Urban mineral deposits? , is it? Resource dislocation? . This is not only the deepening of the understanding of garbage, but also the inevitable requirement of urban development. At present, sanitary landfill, high-temperature composting and incineration are widely used methods of municipal solid waste treatment at home and abroad. The proportion of these three main garbage disposal methods depends on the geographical environment; The composition of garbage and the level of economic development are different.

Investigation results and suggestions on intransitive verbs

(A), the importance of domestic waste classification

With the improvement of our living standard and the increase of daily output, garbage needs a lot of manpower, material resources and financial resources to clear and treat, and garbage disposal also takes up a lot of money.

Although we bury the land deeply, garbage still pollutes the soil, water and atmosphere, which is harmful to health, human health and even human life safety and seriously affects our environment. How to deal with domestic garbage and how to turn waste into treasure is a big problem before us. It is very necessary to classify and recycle garbage, turn waste into treasure, and reuse this underutilized resource. To this end, the government stepped up its rectification efforts, invested a lot of manpower and material resources to carry out garbage sorting, took the road of sustainable development, improved the level of reduction, recycling and harmlessness of urban domestic garbage, improved the living environment, built pilot communities and buildings for garbage sorting, and encouraged citizens to sort garbage, build a green city and do practical things for the people. As the younger generation, we feel great responsibility and significance, but we have found the following points in our work.

1, the garbage classification community has no real classification.

2. Lack of understanding of garbage classification. First of all, leaders at all levels have insufficient understanding, measures and efforts, and have not formed a joint force of society.

3. The propaganda of garbage classification is not strong enough. There is no good social atmosphere, although various forms have been taken, such as training, setting up publicity stations, posting publicity boards, publishing newspapers, publicizing at home and distributing leaflets. It has been adopted in the work of garbage classification. It seems that the propaganda work of garbage classification is far from enough, which requires an overall social atmosphere and the participation of the whole society.

4. There is not enough coordination among departments, and they don't really realize the importance of garbage classification. The government has invested a lot of manpower and material resources in waste sorting communities and buildings, but for various reasons, the waste sorting work has not been really implemented.

(2) In view of the problems found in this survey, I analyzed the main reasons:

1, people don't sort garbage;

2. People's awareness of environmental protection is not strong; And it is not consciously classified;

3. The state has not enacted relevant laws;

4. There are too many harmful waste in the market, and I don't know how to classify them;

5. The classification of garbage bins is not perfect;

6. The knowledge of garbage classification is not well publicized.

(3) My suggestions:

1, design environment rewards and punishments;

2. Cultivate people's conscious awareness of environmental protection;

3. Regularly increase classified garbage bins; And make classification marks, indicating the purpose;

4. Do more environmental protection activities to raise people's awareness of environmental protection;

5. Intensify environmental protection propaganda and make environmental protection a habit;

6, increase the relevant environmental protection laws, and strictly enforce, crack down on environmental behavior.

Findings:

1. Many people don't know the knowledge of garbage classification, and some people don't support the behavior of garbage classification.

Among them, 34.8% people think that the facilities are incomplete and cannot be classified; 30.9% people think it is because of lack of environmental awareness; 13.42% means I don't know how to classify; 13.29% people don't understand the benefits of garbage sorting and recycling; 3. 15% people feel troublesome; 2.3 1% people are out of distrust of functional departments, thinking that all garbage will be put together in the future, and now it is divided in vain; There are also 2. 13% people who think that this move is meaningless. 2. The main reasons why people don't understand garbage classification are:

(1) The government has not conducted relevant publicity and education.

(2) Except professionals, ordinary people in China can basically distinguish the types of garbage by their life experience.

(3) Citizens' awareness of environmental protection is not strong enough. 3. Significance of garbage classification: (1) Reduce land occupation. Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage sorting, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.

(2) Reduce environmental pollution. Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body. Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can reduce the harm.

(3) Turn waste into treasure. 30% of domestic garbage? 40% can be recycled, so we should cherish this small and large resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources. Moreover, other substances in garbage can also be transformed into resources, such as food, vegetation, fabrics, etc., which can be composted to produce organic fertilizer; Garbage incineration can generate electricity, heat or cool; Bricks and lime soil can be processed into building materials and so on. It can be seen that the best way to solve the garbage problem is to classify and recycle the garbage generated in the consumption link in time. Analysis:

As can be seen from the survey results:

1. Most people don't understand garbage classification.

2. Garbage sorting facilities may not be perfect enough.

3. Is the propaganda work of garbage sorting not in place? Solution to the problem:

1. Establish the concept of garbage classification. Carry out extensive publicity, education and advocacy of garbage classification, so that consumers can establish environmental awareness of garbage classification, make clear the serious harm caused by garbage to social life, publicize the significance of garbage classification, and call on consumers to actively participate in garbage classification. At the same time, the knowledge of garbage classification is taught to consumers, so that the garbage classification of consumers gradually becomes a conscious habitual behavior.

2. Transform or increase garbage sorting and recycling facilities. A trash can can be divided into several parts, or several independent classified trash cans can be established. Garbage classification should be gradually refined. The finer the garbage classification, the more favorable it is for recycling. Special garbage such as glass, paper, plastic and metal packaging garbage, plant garbage, household garbage, battery light bulbs, etc., can be recycled in trash cans with different colors. Garbage cans must be marked with recycling categories and brief instructions for use to guide consumers.

3. Improve the form of garbage storage and transportation. For some big garbage, we should compress the storage. In particular, it should be noted that the garbage collection vehicle of the Environmental Sanitation Bureau should be transformed separately and loaded with garbage in different categories. Give full play to the role of the original garbage recycling channels.

Now in some communities, gardens and other places, you can see some colorful trash cans marked with? Recyclable garbage, other garbage, kitchen garbage? Such as Chinese characters, these are classified trash cans. Some people may wonder: in the past, everything was put in the trash can, but now there are so many trash cans. Then let's learn about the benefits of garbage sorting.

First, the background of garbage classification

Garbage is usually sent to the dump first, and then to the landfill. Landfill is expensive, and the cost of treating one ton of garbage is about RMB from 200 yuan to 300 yuan. Beijing alone produces10.2 million tons of garbage every day. At present, there are more than 700 garbage dumps with an area of more than 36 square meters in the Fifth Ring Road of Beijing, with an area of more than 5 million square meters, increasing at a rate of 3-5% every year. People consume a lot of resources, mass production and consumption, resulting in a lot of waste. Another method of garbage disposal is incineration. Although the garbage burned at high temperature will not occupy a lot of land, it not only has high cost, but also increases the risk of secondary pollution. Dioxin is a colorless, odorless and highly toxic fat-soluble substance, which is the main gas produced after incineration.

One of the ingredients. Whether it is landfill or incineration, it is a waste of resources. We constantly turn the limited earth resources into garbage, and then bury or burn them. If this continues, natural resources will be reduced day by day and the quality of human life will be greatly reduced.

From this analysis, we can see that the benefits of garbage sorting are obvious. After sorting, the garbage is sent to the factory instead of landfill, which not only saves land, but also avoids the pollution caused by landfill or incineration, and can also turn waste into treasure. As we all know, good paper is made of wood. One ton of waste paper can recycle 700 kilograms of good paper, cut down less 17 trees, and reduce water pollution in pulp production. In our life, we often throw away all kinds of waste plastics. Waste plastics can also be made into buttons, pen containers and other supplies after treatment. Waste plastics are also good raw materials for oil refining. Some people have vividly compared them to "secondary oil fields". 1 ton of waste plastics can recover at least 600 kilograms of gasoline and diesel.

Second, the development of garbage classification.

In xx community, garbage bins and four-color garbage bags were distributed to designated communities by Huzhou Municipal Leading Group Office for Classified Collection, Disposal and Direct Transportation of Domestic Waste in 20xx. On that day, everyone cooperated with the door-to-door inquiry and inquired about it until they knew it. The volunteers who tutor you also patiently guide you.

A month and a half later, we made another survey and found that except for a few people who haven't adapted to it and put it in the wrong bin, everyone else can sort the garbage well. However, the volunteers who gave us guidance were not there. By asking the security guard, we learned that the volunteer had been working for three days and never came again.

Third, garbage classification survey.

Through the inquiries of old people, middle-aged people and children, I learned some information: most old people will consciously respect the classification of garbage and have a clear division of each kind of garbage, while some middle-aged people are not so good.

Paying attention to this activity, most children can distinguish recyclable and kitchen waste, but they don't know much about other wastes and toxic harmful waste. The following is your understanding of garbage classification:

Know more about 37% and 86%.

Get to know 27,56%?

Generally understand 28,21%?

It's good. 5, 13%?

I know nothing about 1, 28%

Fourth, the follow-up expectations of garbage classification

Generally speaking, the activity effect of garbage classification is still good, but everyone should know more about the benefits of garbage classification and understand garbage classification in order to make greater progress. I hope everyone can cooperate with this work, contribute to environmental protection and give us a bluer sky, brighter sunshine and a more comfortable life!

Personal Investigation Report on Garbage Classification 202 1

First, ask questions.

One day, I saw a picture that said? Recyclable? A trash can with words. Then I put my head in and saw all kinds of rubbish, mineral water bottles, plastic bags and peels. Really? A dazzling array of things? . This shows that the garbage classification in Foshan is not very good, and then we conducted an investigation.

Online answer

What kinds of domestic waste are there in China?

90% people don't know.

Domestic garbage can generally be divided into four categories: recyclable garbage, kitchen garbage, harmful waste and other garbage. At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration and composting. Did the cleaners sort the garbage?

cleaner

Pick up some plastic bottles and cans, and don't sort other rubbish. Cleaner 8: There is garbage sorting. Do you know what kind of garbage is put in which trash can? Do you know how to put garbage according to the sign of the trash can? 90% people throw rubbish when they see the trash can.

What are the benefits of garbage sorting?

70% people don't know.

(1) Recover renewable resources. (Paper, glass, scrap metal, plastic and other resources can be recycled)

(2) Conducive to the disposal of toxic and harmful substances. (such as waste batteries, etc.). )

(3) It is beneficial to the utilization of resources. (For example, organic waste can be made into fertilizer)

What measures should be taken to change the status quo?

60% don't know.

Four. conclusion

1. The garbage disposal in one city may change the whole city, and if it is not handled properly, it will do great harm to the environment of the city. However, the survey found that Foshan people's awareness of environmental protection is not very strong, especially garbage sorting. Most of those trash cans are not sorted. Many people use disposable plastic bags when shopping or buying food. Also, some people throw cigarette butts into the trash can. If there is paper in it, it is easy to cause a fire. Most cleaners only pick up some plastic bottles and cans. Although some people know about it, in fact, many people are too troublesome to do it. Many elderly people don't know about it at all. I think one of the reasons may be that the publicity of the municipal government is not enough. But it is gratifying that the phenomenon of littering has been greatly improved! But it's really bad that garbage is not classified. For example, the decay of waste batteries will cause soil erosion and pollute the environment; Some garbage bags will produce a lot of toxic gases such as carbon dioxide in the air if they catch fire, which is very harmful to human body. Therefore, the classification of urban garbage is very important!

I think we should learn some successful experiences from foreign countries, such as Japan, Singapore, Holland and Canada. For example, in the Netherlands, they have many recycling bins for individual items. Japan can only recycle four big pieces a year. Wait, these are all worth learning! that

In fact, it is the wisest choice to start from the little things around you and develop the awareness of garbage classification from an early age!

3. I hope the garbage sorting situation in Foshan can go up a storey still higher!

Interesting homework

? Reporter? This word doesn't sound suitable for me as a primary school student, but this time I really felt the taste of being a reporter.

Why do you say that? That's because this weekend, the teacher assigned me a quite innovative task!

What about this? Quite an innovative task? What is this? It was on the second day of school that the teacher called me and several classmates together and asked us to make an investigation report on garbage classification. In groups of three, look up relevant information on the internet, visit relatives around or garbage workers in the community, and finally write an article and give it to the teacher. When everything was explained one by one, two friends and I immediately formed a small investigation team, and the work began immediately!

In my impression, garbage sorting is a simple and common problem, and adults should be very clear about it. But I asked a few relatives and found that they knew almost nothing about garbage classification! And among the people they know, very few people know more about garbage classification, which shocked me greatly.

Very surprised. At this time, the students in charge of online search have found a lot of information, but most of them are about foreign countries, and the domestic information is simply pitiful. This gradually caused a question mark in my heart: Didn't China pay attention to the problem of garbage sorting? But that's impossible. Because of statistics, if garbage is classified, at least 30% and 40% can be used; Recycling one ton of waste paper can regenerate 0. 85 tons of new paper can save a lot of energy this year! China, which has always paid attention to energy conservation, can't find it? I thought hard and searched online, and finally got the answer on a text-intensive web page.

Facts have proved that it is quite difficult to popularize the knowledge of garbage classification. One. China has a large population and a large area, and the scope of publicity is quite large, so it can only be publicized in several big cities first, so many small cities are very vague about this concept; Two. Nowadays, the competition is fierce. Many people just want to make money every day and pay little attention to these so-called? Little things? .

Even if he knew this knowledge, he ignored it; Three. China began to advocate it in recent years, so naturally it can't compare with foreign countries.

Therefore, the popularization of garbage sorting will take a long time!

Although it will take a lot of time, as long as we all contribute, I believe the time is not short, but it won't be too long. Let's work hard for the popularization of garbage classification knowledge!
