Primary school garbage classification 600 words fourth grade composition 5

Garbage sorting is imminent! If all the garbage can be classified according to the requirements, it will bring great convenience to garbage disposal. The following is an example of a 600-word composition for the fourth grade of primary school garbage classification. I hope you like it.

In our daily life, we produce a lot of garbage, such as packaging bags, leftovers, waste paper, plastic products ... Many people put the garbage directly into the trash can without sorting it. Although it is convenient for them, it will cause great waste on resource utilization.

Some rubbish seems useless to us, but in fact they are real treasures. For example, waste paper is the material of recycled paper, and 6.5438+0 million tons of waste paper can be reused, which can avoid cutting down 600 square kilometers of forest, greatly save energy and protect our ecological environment. As we all know, many resources are non-renewable. If we pay attention to sorting when dumping garbage, so that the available garbage can be recycled, our earth will be more environmentally friendly!

Garbage can be divided into recyclable and non-recyclable according to its use. Recycling includes waste paper, plastic, glass, metal and cloth, which can be reused after treatment. Non-recyclable garbage includes: kitchen waste, other garbage, and harmful waste, all of which have different disposal methods.

The pace of human exploration of "garbage classification" has never stopped. I heard that more advanced practices were even published in People's Daily. At present, many communities have a "two-dimensional code intelligent garbage sorting box", in which garbage bags have two-dimensional codes, and residents can put in garbage by scanning the two-dimensional codes and weighing them. In addition, the community has specially set up recyclable garbage bins. This eye-catching logo is not only convenient for everyone to find a suitable location, but also can make more rational use of resources.

As primary school students, we should do our best to contribute to the good habit of garbage sorting, and at the same time, we should always remind people around us to develop such good habits.

Let's seriously classify garbage for the same family, and let garbage classification become our habit! I want to shout loudly: garbage sorting, starting from me, protecting the environment, everyone is responsible!

On weekends, my mother will be busy doing housework and cleaning up the rubbish at home. I also rolled up my sleeves and helped my mother with her work.

Soon, the small yard was full of all kinds of rubbish, including shoe boxes, empty milk boxes, discarded pens, pencils and erasers ... all kinds.

I said in surprise, "Mom, why are you wasting so much?"

"Yes, you ride grandma's tricycle quickly, then load the garbage and throw it into the trash can."

"Very good." When I pushed a tricycle full of garbage into the garbage bin at the entrance of the village and was ready to throw it, an aunt came over and said to me with a smile, "Little girl, don't throw it in a hurry, these garbage are still useful!" You can classify them. "

"What's the use of garbage?" I'm confused.

"Garbage is garbage only when it is mixed together. Once classified and recycled, it is a treasure. " Aunt said as she piled up the old cartons, put the old clothes together and put the scrap iron on the other side. ...

"all right! These scrap metals belong to non-recyclable garbage, and we can put them in non-recyclable garbage bins. These rags and cartons can be recycled, so you can sell them! "

Under the guidance of my aunt, I came to the waste collection station. Unexpectedly, those waste paper boxes and old clothes were sold to 16 yuan.

After returning home, I looked up the information about garbage classification on the Internet. I just know that all garbage has its own ownership, and some substances in garbage can also be transformed into resources, such as expired food, vegetation and fabrics, 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. It turns out that garbage mountain can also be turned into golden mountain.

Let's start from ourselves, do a good job in classifying domestic garbage and protect our green living environment!

Primary school garbage classification 600 words fourth grade composition 3 Although Guangzhou has a rapid economic development and is a relatively advanced city in China, its environmental management is relatively backward and garbage is expanding day by day. If it is not effectively dealt with, the "garbage siege" is probably not fiction. Therefore, under such conditions, Guangzhou has classified garbage.

As a native of Guangzhou, I actively participate in the garbage sorting and recycling work in Guangzhou.

However, the government's propaganda is obviously insufficient. For example, recyclable garbage is blue, kitchen waste is green, harmful waste is red, and other garbage is gray. These basic knowledge are also learned by ourselves through various channels.

But there is no doubt that the garbage sorting in Guangzhou is undoubtedly exploring the way out in the future. There is too much rubbish to be buried like this. On the whole, the deterioration of the ecological environment in China has been initially contained, and some areas have improved, but the current environmental situation in China is still quite grim, which is not optimistic.

Therefore, garbage sorting is imminent. Why?

We constantly turn the limited earth resources into garbage, and then bury or burn them. Where will our descendants live?

Garbage classification is to put garbage into the source, and make it become a resource again through sorting, cleaning and recycling.

The advantage of garbage sorting is that it is sent to the factory instead of the landfill after sorting, which not only saves land, but also avoids the pollution caused by landfill or incineration, and can also turn waste into treasure. Isn't that great?

Although we can't have the brains of scientists to develop better ways to deal with garbage, although we don't have the skillful hands of magicians to make garbage disappear, we can classify garbage ourselves. I believe that our tomorrow will be better, and we can also contribute to the creation of a national civilized city in Guangzhou.

Finally, I appeal to you: Do your best to do a good job in garbage sorting, you are the best!

In the city where we live, every family produces some domestic garbage every day, so the amount of garbage in a city every day is considerable. Garbage can be seen everywhere in our lives. If the garbage is not properly cleaned up, the blue sky and white clouds are a distant dream. So what should we do with these domestic wastes? That's sorting garbage.

Garbage classification can be divided into recyclable garbage, wet garbage, hazardous waste and dry garbage.

The recyclable trash can is blue, which mainly includes five categories: waste paper, plastic, glass, metal and cloth. These can be comprehensively treated and recycled to reduce pollution and save resources. For example, every 1 ton of waste paper can be recycled into 850 kilograms of paper, saving 300 kilograms of wood.

The wet trash can is green, mainly including leftovers, cakes and other food residues, bones and internal organs, vegetable roots and leaves, fruit residues, stone peels, bonsai and other plant leaves, waste cooking oil, tea residue and other food wastes. After field treatment and biotechnology composting, 0. 3 tons of organic fertilizer.

Hazardous trash cans are red, including waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, mercury thermometers, paint buckets, household appliances, expired cosmetics, etc. These wastes need special safety treatment.

Dry trash cans are gray, including bricks and tiles, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle except for the above types of garbage. Usually, according to the characteristics of garbage, it is disposed by incineration or landfill. Contaminated and non-renewable paper, contaminated or other non-recyclable glass, plastic bags and other contaminated plastic products, textiles such as waste clothes, waste ceramics, disposable tableware, shells, cigarette butts, dust, etc.

In fact, garbage sorting is not difficult, just a matter of our hands. For our homeland, for our tomorrow, from today on, everyone will actively participate in garbage sorting. * * * Create a beautiful community environment, cooperate with garbage sorting, and strive to be civilized citizens together!

Since the implementation of garbage sorting in Shanghai, hilarious jokes have emerged in an endless stream, which makes people feel funny and makes people curious about the reasons behind garbage sorting! So, why should we classify garbage?

The traditional garbage sorting treatment methods mainly include incineration, landfill and composting. At present, many people are not aware of the danger of garbage not being classified. Garbage mixed together, no matter what treatment method, the harm is enormous. If ordinary landfills are used, garbage can only be slowly degraded by itself. The degradation time of garbage is as short as two weeks and as long as two million years, especially plastic garbage, which can be seen everywhere in our lives! So: "garbage is easy to discard, not easy to degrade, but also can be cherished!" " "If you burn a lot, it will pollute the air and the environment! The harmful gas it emits is easily inhaled by us humans, causing respiratory diseases! After composting, the degraded harmful substances will destroy groundwater resources! Therefore, "it is everyone's responsibility to protect the earth! "The earth is our home, and greening depends on everyone.

Countless animals die every year because of eating garbage by mistake. A lot of garbage floats in the sea, and marine animals suffer greatly-a stranded whale's stomach is full of plastic garbage, which can cover the deck of a ship. Really shocking! Seeing this, some people will say, "What's it to us?" Then I want to refute: "How do you feel when you live in an environment full of garbage and rotting animal carcasses?" When garbage sorting workers work day after day, year after year, and their bodies are seriously injured because of harmful waste, isn't everyone responsible? Therefore, garbage sorting is necessary and necessary! Mixing garbage is harmful. When it is classified, it will turn waste into treasure and become a renewable resource.

We should start from the small things around us, accumulate the knowledge of garbage classification bit by bit, make our home better, and tell the world that there is nothing we can't do, only things we don't want to do! We also firmly believe that as long as each of us persists, one day, the dark river will become clear again and the cloudy sky will become blue. ...
