Investigation report on garbage classification

Model essay on garbage classification investigation report

If you want to know something you don't know, you need to make a careful investigation and study the obtained materials in detail, and finally form an investigation report. But what are the requirements of the investigation report? The following is a sample of the garbage classification report I collected. Welcome to share.

Investigation Report on Garbage Classification 1 I. Question Raising

One day, I saw a trash can with the words "recyclable" written on it. Then I put my head in and found all kinds of rubbish, including mineral water bottles, plastic bags and peels ... it was really "dazzling" and "everything" This shows that the garbage classification in Foshan is not very good, and then we conducted an investigation.

Second, the survey object

Passers-by and (community) cleaners

Three. Investigation and data collation

Investigation task

Survey answer

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 1.6: No, the garbage is not classified. Cleaners 2, 3, 4, 5, 7, 9, 10: Pick up some plastic bottles and cans, and other garbage will not be classified. Cleaner 8: There is garbage sorting.

Do you know what kind of garbage is put in which trash can? Do you put rubbish according to the sign of the trash can?

Know; 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; If some garbage bags catch fire, they will produce a lot of toxic gases such as carbon dioxide in the air, which is very harmful to human body. Therefore, the classification of urban garbage is very important!

I think we should learn from the successful experiences of some foreign countries, such as Japan, Singapore, the Netherlands 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! 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!

Verb (short for verb) experience

Interesting homework

The word "reporter" 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!

So what exactly is this "quite innovative task"? 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. 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%-40% can be used; Recycling one ton of waste paper can regenerate 0. 85 tons of new paper ... I don't know how much energy can be saved 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, and many people just want to make money every day, paying little attention to these so-called "small 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!

Investigation report on garbage classification II. The proposition of the problem:

We live in this world. No matter what we do, we produce garbage every day. So how to deal with these rubbish is correct, and how can we do it without hurting human beings?

Second, the purpose of the investigation

1, understand the correct method of garbage disposal.

2. Enhance environmental awareness.

3. Improve your investigation ability.

Third, the method of investigation.

1, consult books

Step 2 interview people around you

3. Online inquiry

4. Go deep into reality and investigate in person.

Fourth, the content of the investigation

1, the phenomenon of littering on the road

2. Garbage cans and cleaning in streets and communities.

3. Classification of domestic waste.

Verb (the abbreviation of verb) investigation preparation:

Before the investigation, we investigated the harm of garbage and the information of online garbage classification. Data show that harmful substances in garbage will pollute soil, air and water, which not only wastes resources, but also seriously damages the ecological environment. After a large amount of garbage is piled up, biological decomposition will occur in the garbage dump, and methane gas will be produced during the decomposition process, and methane gas will easily explode when it gathers to a certain extent; Garbage is rich in protein, lipids and sugars. At room temperature, NH3, H2S and harmful hydrocarbon gases are produced in the process of decomposing organic matter by microorganisms, which have obvious stench and toxicity and directly harm human body. If discarded electronic and electrical products are randomly discarded and scattered into the environment, it will do harm to human health and destroy the ecological environment. For example, harmful heavy metal elements contained in e-waste will harm the water environment and the health of surrounding residents for a long time once they enter the water body. In addition, the freon contained in refrigerants and heat preservation foaming agents of refrigerators and air conditioners, once leaked, will destroy the atmospheric environment, and then bring harm to human health! If human beings don't take measures to properly dispose of garbage, eventually human beings will be retaliated and can't find the pure land for survival.

Natural degradation schedule of garbage

Paper for 3-4 months; Cigarette butts 1-5 years; Orange peel for 2 years; Tin cans are 20xx years; Nylon fabric for 30-40 years; Leather for 50 years; 80- 120xx tanks; Plastic 100—220xx years; Glass bottle 4020xx and wool fabric 1-5 years.

Garbage classification table:

Recyclable garbage: paper, metal, plastic, glass, etc.

Kitchen waste: food waste such as leftovers, bones, roots and leaves.

Hazardous wastes: waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc.

Other garbage: bricks, tiles, ceramics, muck, toilet waste paper and other wastes that are difficult to recycle.

Sixth, the investigation process.

A team investigated residential areas and vegetable markets.

Survey process and feedback:

1, the phenomenon of littering on the road

We took a trash can near Nanyuan Community as the observation point. In the morning, the trash can was just cleaned and empty.

Young man: Throw away the banana peel when it is 5 meters away from the trash can.

Fashion woman: Holding her nose, like running away, she threw away the garbage bag and left.

Middle-aged man: He passed the trash can, came over and threw the cans into the nearby river.

Elementary school students: properly throw the leftover food packaging bags into the trash can.

Old woman: Carefully bypass the trash can and throw the garbage bag into the trash can. ...

Findings:

An hour later, only three of the 13 people who took out the garbage threw it into the trash can. Garbage is piled around the trash can, and flies are flying on it.

2. Garbage cans and cleaning in streets and communities.

From the vegetable market to the experimental primary school: there are 10 unclassified trash cans along the way, and there is little garbage in the trash cans. At that time, when street vendors were collecting stalls, there were many broken leaves and fruit branches and leaves on the ground, which were very dirty. But after 1 hour, it has been cleaned by the cleaner.

Yiyuan Community: There are large and small trash cans and garbage rooms in the community. The opening of the small trash can is only about 10 cm high, and the slightly larger garbage bag can't be put in. Some people put rubbish in the trash can for convenience. The situation of the big trash can is better. The garbage in the garbage room is the responsibility of the cleaner, and there is no littering.

Lan Song Community: Garbage cans in the community can be recycled and non-recyclable, and the road surface is clean. Although the outside of the dustbin is clean, there is no distinction between recyclable and non-recyclable inside, but littering. Recyclable garbage such as paper and cans is mistakenly thrown into the non-recyclable category. Toxic wastes such as waste batteries, waste fluorescent tubes, expired drugs and waste water silver thermometers are mixed into recyclable categories.

The second group surveyed residents and students.

Survey process and feedback:

1, 10 households were investigated in the community.

For garbage classification, only 2 households in 10 know and are willing to classify. And five households know and are willing to classify, but sometimes the lid of the trash can is small and there is a lot of garbage, which is too troublesome. Two families know but don't want to classify, because it's too much trouble to do. 1 users don't even know the classification.

2. Investigate the garbage disposal methods of 20 students.

5% of the garbage is classified and bagged, 1% burned, 1% buried, 90% thrown into the dustbin, and 3% thrown casually.

Investigation results: The correct method of garbage disposal: recycle the available garbage, classify all kinds of recycled garbage, and then transport these garbage to agents or factories for further processing to make other items. This method is effective and economical, and the garbage will not be polluted. Organic waste is composted at high temperature, burned and buried in hazardous waste.

Seven, thinking and suggestions

We sorted out the survey results, expressed our opinions and summarized the following suggestions:

1. Setting up classified garbage bins requires an overall planning and system configuration, not surface engineering, because it is a matter of living habits and quality of life for everyone to classify and throw garbage;

2. Mark eye-catching patterns or text descriptions on the sorting trash can, so that when you throw garbage, you can easily and accurately sort the garbage;

3. Let everyone experience the practical benefits brought by garbage sorting and throwing. For example, in a community with good garbage classification, it is not only a matter of saving several tons of water fees, but also an honor and a socially recognized public welfare act.

4. Buy food with your own basket and refuse to use disposable plastic bags. Promote the use of environmentally friendly plastic bags, improve technology, reduce costs, and improve utilization value, such as advertising on packaging bags;

5. Use sterilized chopsticks when eating, and refuse to use disposable chopsticks. We advocate the use of handkerchiefs after meals and refuse to use napkins;

6. Call on people to eat as much as possible when cooking, especially in restaurants, to avoid waste and solve the problem of swill;

7. About littering, it is easy to do but forgotten by people. If you impose heavy penalties like Singapore, you should also receive miraculous effects.

I read a news in the newspaper before: On the second day of the Golden Week of November, more than 80 Korean tourists, including more than 30 children, collectively picked up garbage in Nanshan Scenic Area of Urumqi. These guests from afar spontaneously organized themselves to clean up the garbage. In just 20 minutes, nearly 1 km of garbage in Fiona Fang was cleaned up. Korean tourists can continue to play with peace of mind after driving five cartons full of garbage to the garbage station.

Although the actions of Korean tourists are small, they are thought-provoking. The earth belongs to everyone, and green civilization is formed under the protection of people. Only by making garbage "belong to everyone" can a green civilization be formed; Green civilization is formed by keeping bad habits away from the human body ... May we really find the green civilization in our hearts as soon as possible.

Investigation report on garbage classification 3 With the development of social economy, environmental pollution is becoming more and more serious, and urban garbage can be seen everywhere. According to relevant data, in the past 10 years, the urban garbage in China increased at an average annual rate. Two thirds of the 400 large and medium-sized cities in China are surrounded by garbage. China has accumulated 6 billion tons of garbage over the years, occupying about 500 million square meters of land. At present, China is still producing hundreds of millions of tons of new garbage every year. How are these rubbish produced and how are they treated? These problems aroused our great research interest.

First, the current situation investigation:

In the morning, garbage can be seen everywhere on both sides of the street. Some are wrapped in plastic bags, some are thrown on the ground at will, and some are put in trash cans.

Passing by the hospital, I saw some expired drugs, discarded mercury thermometers, some medicine bottles and infusion sets abandoned in the corner of the hospital. These rubbish give off a pungent smell, which makes me afraid to go near.

In the corner of the factory building, abandoned batteries, old machines, circuit boards, broken glass and broken wood boards piled up into mountains. The battery was damaged and the liquid in it leaked out. Waste batteries are called "mini killers". We can imagine how much harm these waste batteries will do to the land after they penetrate into the soil.

In the vegetable market, discarded fish and vegetables are piled up on the road at will, and flies are buzzing. This surprised me. Are all the foods you can't buy thrown away at will?

A sanitation worker told me that these mountains of garbage were sent to a certain place for landfill or incineration.

Second, the harm of garbage:

Disposing of garbage at will is potentially harmful. How much land does it take to turn such a large amount of garbage into a landfill? How many toxic gases will be produced during incineration, which will endanger people's health? We constantly turn the limited earth resources into garbage, bury or burn them. Where will our future generations find the energy they need in a long time?

Third, the garbage classification treatment:

Are we helpless about the pollution of garbage? No, according to our investigation, garbage can be generally divided into four categories: recyclable garbage, kitchen waste, harmful waste and other garbage.

Recyclable garbage is directly sent to relevant factories for reprocessing and waste utilization. For example: 1 ton waste paper can be recycled into 800 kilograms of good paper; Rare metals such as zinc, copper and manganese dioxide can be extracted from recycled batteries; The recycled waste plastics can be recycled into fuel.

Kitchen waste, such as leftovers, lettuce, eggshell skin, cabbage leaves, etc. , can be piled up, let waste fiber and organic matter decay, into fertilizer, improve the soil.

In harmful waste, such as waste fluorescent tubes, expired drugs, etc., can be burned together, so as to minimize the harm of garbage.

Other garbage, such as ceramics and dregs, is difficult to recycle and has no harm to the environment. It can be effectively landfilled and reduce the pollution to groundwater, soil and air.

Fourth, our thinking:

Relevant statistics show that the value of waste that can be used but not used in China reaches 25 billion yuan every year, and about 3 million tons of scrap steel and 6 million tons of waste paper are not recycled. The recovery rate of waste plastics is less than 3%, and the recovery rate of rubber is 3 1%. Only more than 6 billion waste dry batteries contain more than 70,000 tons of zinc and 654.38+10,000 tons of manganese dioxide every year. Garbage sorting and recycling is of great value;

Waste paper:

Recycling waste paper 1 ton can regenerate 800 kilograms of good paper, save 0/7 trees/kloc-0, save 3 cubic meters of landfill space, save 240 kilograms of soda ash, reduce papermaking pollution emissions by 75%, and save papermaking energy consumption. Each paper can be recycled at least twice.

Waste plastics:

Plastics come from oil, which is a non-renewable resource on the earth. Recycling waste plastics is to save oil. All waste plastics, waste lunch boxes, food bags, woven bags, soft packaging boxes, etc. It can be recycled into fuel by reducing waste plastics into gasoline and diesel oil; 1 ton of waste plastics can produce 10 liter of unleaded gasoline or diesel oil.

Waste glass:

Recycling waste glass can not only save natural resources, but also reduce energy consumption by about 32%, air pollution by 20% and water pollution by 50%. Recycling 1 ton of waste glass saves 20% of the cost compared with using new raw materials. The benefits of recycling one ton of waste glass to the environment and resources are: 720kg of quartz sand, 250kg of soda ash, 60kg of feldspar powder, 0/0t of coal/kloc and 400 kwh of electricity can be saved.

Discarded aluminum cans:

After the waste cans are dissolved, they can be recycled 100% for countless times to make new cans, and can also be made into parts of cars, planes and even furniture. Recycling aluminum cans can save 95% of the energy needed for new aluminum cans and reduce 95% of air pollution. Discarding an aluminum can is equivalent to wasting half of the oil in the aluminum can.

Organic matter:

More than 40% of the garbage we still leave home every day is kitchen waste such as peels, eggshells, vegetable leaves and leftovers, which can be treated as organic fertilizer or feed by composting and fermentation.

Waste battery:

Mercury and cadmium contained in waste batteries are toxic heavy metals with high pollution, but rare metals such as zinc, copper and manganese dioxide can be extracted from recycled batteries.

Verb (abbreviation for verb) Our suggestion:

1, let people understand the importance of garbage classification through publicity;

2. Set up sorting bins in residential areas, vegetable markets, hospitals, factories and other places to facilitate sanitation workers to sort all kinds of garbage.

Garbage is a public hazard, but as long as we use the method of garbage classification to deal with it, we can completely turn garbage from enemies into friends.

2. Investigation report on ceramics

Today, we went to Zhejiang Museum to do a survey on ceramics. We are divided into two groups, A and B. Group A investigates pottery in the exhibition hall on the first floor and Group B investigates porcelain on the second floor. I joined group a.

After reading the introduction and listening to the explanation, I know that pottery and porcelain are not the same thing. Pottery appeared before porcelain. Pottery is a container made of small particles of soil. In ancient times, pottery was mainly used for sacrifice and burial.

Porcelain appeared in the Eastern Han Dynasty, and the surface of pottery was coated with a smooth glaze. According to the different glaze colors, there are many kinds of porcelain, such as celadon and white porcelain ... the famous celadon, because of its iron content, presents a jasper-like cyan. "

In ancient times, pottery and porcelain were used for sacrifice, inheritance and other activities. In modern times, ceramics have become daily necessities, which can help people to wash rice and serve rice, and become an indispensable item in family life.

Ceramics are indispensable in ancient and modern times, and they are the crystallization of the wisdom of the ancient working people in China.
