Essay on the topic of garbage classification 1

The earth is our home, which is surrounded by garbage. The earth's resources are also limited, so it is urgent to protect the earth's environment. Therefore, we should classify garbage and reuse these available resources.

At present, new garbage classification regulations have been promulgated, which divide garbage into four categories: dry garbage, wet garbage, recyclable garbage and harmful waste. Wet garbage mainly includes leftovers, western cakes and other food residues, vegetable stems and leaves, animal bones and internal organs, tea residue, fruit residue, fruit shells and peels. Dry garbage includes napkins, toilet paper, diapers, cat litter, dog pads, decals, cigarette butts and < P > these wastes are piled up by biotechnology, and .3 tons of organic fertilizer can be produced per ton. Garbage sorting can also reduce the damage to surface plants and reduce the pollution to groundwater and air. At present, global warming is closely related to our daily burning of garbage. The rational utilization of garbage can not only benefit the people, but also protect our homes on which human beings depend.

Nantong Yongxing Garden Community has carried out the environmental protection activity of "garbage sorting, starting with dolls" in kindergarten, which deserves respect! Let dolls have a sense of garbage sorting since childhood, and achieve the goal of "educating a student, driving a family and civilized the whole society". Similarly, only by constantly improving the quality of the public can waste classification be better promoted and implemented.

In our daily life, there are several trash cans in our home. For example, the kitchen garbage can be put in a trash can, and the dry garbage in our life can be put in another bucket. Garbage harmful to human body is specially put into the trash can. The community should also often do publicity activities to urge residents to classify garbage and let them know the benefits of garbage classification. On the other hand, it is necessary to incite the change of behavior pattern through measures such as personnel investment and economic compensation, so as to deepen understanding and cultivate self-awareness.

This month, garbage classification once became a hot topic. As a primary school student, let's talk about this topic with you today!

First of all, we should know that garbage can be divided into four categories, namely recyclable garbage, kitchen waste, harmful waste and other garbage. Next, let me tell you something about garbage classification.

At present, the common garbage disposal methods are comprehensive utilization, sanitary landfill, incineration and composting.

recyclable garbage: including newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, paper boxes, etc., but it should be noted that paper towels and toilet paper are too water-soluble to be recycled. Plastics: mainly include all kinds of plastic bags, plastic packaging materials and disposable plastic articles, such as toothbrushes, cups and mineral water bottles. Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs and so on. Metal objects: mainly include cans, cans and so on. Cloth: discarded clothes, tablecloths, towels, schoolbags, shoes, etc.

Kitchen waste mainly includes food wastes such as leftovers, bones, roots and leaves.

harmful waste does not properly handle the garbage that may cause harm to the environment. Such as fluorescent tubes, dry batteries, various chemical batteries and other harmful substances.

Other wastes include bricks and tiles, waste residue, toilet paper and other wastes that are difficult to recycle. Sanitary landfill can effectively reduce the pollution to groundwater, surface water, soil and air.

through my introduction to garbage and garbage classification, have students learned a lot? If you understand, please join me quickly! Essay on the theme of garbage classification 3

Now we live in a new era of the 21st century, and all kinds of technologies and civilizations have made great progress and breakthroughs. However, our environmental problems are getting worse day by day. Serious environmental deterioration and pollution accidents are frequently reported all over the country, which not only brings extremely bad effects to residents' health, but also causes people to reflect. Have you noticed the small details of environmental protection around us?

At ordinary times, we don't seem to notice these small details at all. We often throw some domestic garbage, including old batteries, recyclable or non-recyclable garbage, together and throw them into a big garbage bin, ignoring the colorful sorting garbage bins next to us. This is really very convenient, so we don't have to try our best to sort the garbage and throw it away one by one. I don't know why we have to try our best to sort the garbage.

Every one of us throws out a lot of rubbish every day. Do you know where these rubbish have gone? They are usually sent to the dump and then to the landfill. The cost of landfill is high, and the cost of treating one ton of garbage is about RMB from 2 yuan to 3 yuan.

The reason for the increase of garbage is the improvement of people's living standards and the increase of various consumption. According to statistics, in 1979, the removal amount of urban garbage in China was more than 25 million tons, and in 1996, the removal fee of urban garbage was 1.16 yuan/ton, four times that of 1979.

at present, another garbage disposal method widely used in western countries is incineration. Although the garbage incinerated at high temperature will not occupy a lot of land, it will not only cost a lot, but also increase the risk of secondary pollution. Dioxin, a highly toxic carcinogen that makes people talk about "evil" color change, is one of the main gas components produced after garbage incineration.

In addition, both landfill and incineration are unnecessary waste of resources. We constantly turn the limited earth resources into garbage, and then bury or burn them. Where will our future generations live?

can't we do anything about garbage? In fact, there is a way, and this is garbage sorting. Garbage classification is to put garbage into the source by classification, and make it become a resource again through sorting, clearing and recycling.

the benefits of garbage sorting are obvious. After the garbage is sorted, it is sent to the factory instead of the landfill, which not only saves land, but also avoids the pollution caused by landfill or incineration. Essay on the theme of garbage classification 4

Every day at six o'clock in the afternoon, my grandfather will put on his blue overalls that have been washed a little white, take all the trash cans at home, and discharge them well. Then he will bring three garbage bags printed with recyclable garbage, dry garbage and wet garbage, and then move a small stool to sit in front of the trash cans. People who are familiar with him will know that he is sorting garbage again.

Grandpa reached into the trash can with his trembling hand and took out a milk carton. I saw him holding the milk box in his hand, looking at it carefully, tearing it apart and smelling it, frowning and shaking his head, holding the milk box and calling back to me: "Tang Xiaoniu, go and wash it and bring it to me!" I thought to myself: Grandpa is really, do you still want to collect this shit? I dislike holding the milk box with my right thumb and forefinger, covering my nose with my left hand, putting the milk box under the faucet and flushing it again and again. It is clean and smells like no milk. Who knows that grandpa took my clean milk box and cut it open directly, dried it and threw it into a recyclable garbage bag!

I was suddenly unhappy and pouted and shouted, "Grandpa! I finally cleaned it, so why did you throw it away again! Didn't I wash it for nothing? " Grandpa said: "Cleaning is recyclable garbage, which can be reused! If it is not cleaned, it will be dry garbage, and it will be burned and wasted. " I nodded and thought what grandpa said was reasonable. Grandpa took out a piece of wet tissue from the garbage bag and threw it into the dry garbage bag. I quickly stopped him: "Grandpa, it's wet. You have to throw wet garbage!" " He smiled at me and said, "Wet paper towels are also dry garbage, and wet garbage generally refers to kitchen waste!" " After that, I went on with his garbage classification. While choosing, I kept chanting: "This is dry garbage, this is recyclable garbage, and this is wet garbage ..."

Looking at Grandpa's busy back, it suddenly occurred to me that the ocean is polluted by garbage, the forest is occupied by garbage, and batches of garbage are destroying our beautiful environment. I looked out of the window, and the sanitation workers were sweeping the floor in the street. There was a lot of rubbish in the dustpan, and there were countless rubbish in the street. Grandpa, isn't garbage sorting equal to protecting nature? If everyone in the world contributes to protect the environment, will there still be rubbish in the ocean? Will there be rubbish in the forest?

I began to fantasize about the future: in the lake, fish are shallow; In the forest, the layers of forest are all dyed; In the desert, there are oases ... Our earth is getting better and better every day ... The essay on the theme of garbage classification 5

Garbage is an essential thing in everyone's life, so do you know what to do with the garbage in our life? Then I'll tell you. On the morning of December 2th, I visited the Baishuitang Domestic Waste Treatment Plant in Beihai.

In the teacher's explanation, I learned that garbage can be divided into five categories: kitchen waste, other garbage, recyclable garbage and non-recyclable garbage, harmful waste. Garbage sorting not only beautifies the environment, but also recycles garbage, which can save the development of new resources, thus fundamentally reducing garbage and participating in environmental protection. Let's start with the small things around us and start with the correct disposal of garbage. After the teacher's explanation, I learned to reduce garbage production in my later life. Garbage is classified.

a day's garbage cleaning process, cleaning and operation. In the early morning, sanitation workers clean and classify the garbage, sweep it, collect it, transport it to various collection stations, then transport it to Beihai Domestic Waste Center Transfer Station for compression through various trucks, and finally transport it to Beihai Waste Treatment Plant for harmless treatment. Domestic garbage landfill: when the garbage truck arrives at Beihai garbage treatment plant, it first weighs the garbage and records the data for statistics and analysis. After weighing, it arrives at the cleaning site, where it is dumped on the working platform, paved by loaders and bulldozers, compacted by compactors and covered by spraying fly-killing and deodorizing agents. When the garbage dump reaches about 5 meters, the workers will cover it with a layer of 15 to 2 cm thick soil. Repeatedly, the landfill waste will undergo biological and physical changes, and decompose organic matter to achieve the purpose of reduction and harmlessness. In order to reach the elevation of the garbage dump and exposed garbage on the working surface, impervious membrane or soil is used for intermediate or temporary covering, so that rainwater and sewage can be diverted, which not only reduces the emission of odor, but also reduces the amount of leachate and reduces the cost of leachate treatment. During the construction of landfill site, landfill gas collection and exhaust device and gas exhaust and exhaust system are installed to collect and exhaust a large amount of landfill gas generated in the process of garbage decomposition to flare system for combustion treatment, so as to achieve the effect of landfill purification.

I learned a lot about daily life this time. We should advocate low-carbon life, reduce the generation of domestic garbage, and make our living environment more beautiful and the air fresher. Essay on the topic of garbage classification 6

“what? Where am I? "I doubt. "Are you all right?" "Did you take the wrong medicine?" "Where is this!" Not school or somewhere! "Said a man my age.

Recyclable garbage will be directly converted into the second recycling in my body, and after treatment and processing, it will become a lovely toy for children to play with. Harmful waste was disinfected by me at high temperature, then burned, disinfected and turned into purified balls. If this purification ball is put into sewage, the sewage will become mellow and delicious.
