How to write a 600-word composition about garbage classification?

(1) 600-word garbage classification composition is urgent!

In recent years, the environmental pollution in China is particularly serious, and protecting the environment has become a big problem for everyone. Protecting the environment starts with me. As a small member of the city, we should also fulfill this responsibility. People's living standards are gradually improving, but garbage pollution is increasing day by day. What should we do with the garbage? Don't throw away discarded batteries at will, because discarded batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body; Waste plastics should not be buried underground, because it takes a long time for plastics to dissolve, and it will also lead to crop yield reduction; Don't throw away waste plastics casually, so as not to be eaten by animals, which will lead to animal death and accidents. Therefore, recycling garbage can not only recycle resources, but also protect the environment. It's just a simple matter to sort out the garbage, and it can also add a love to our city.

Recyclable garbage mainly includes paper, metal, plastic, glass and so on. Through comprehensive treatment and recycling, pollution can be reduced and resources can be saved. Kitchen waste includes food waste such as leftovers, bones, vegetable roots and leaves. After in-situ composting by biotechnology, 0.3 tons of organic fertilizer can be produced per ton. Hazardous wastes include waste batteries containing mercury, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment. Other wastes include bricks and tiles, ceramics, muck and other wastes that are difficult to recycle except the above-mentioned wastes. Incineration or sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

Food waste accounts for about 1/3 of the total life. Kitchen garbage and other organic garbage are characterized by dispersion, large quantity, difficult treatment and easy pollution to the environment. Centralized treatment, such as composting, not only reduces the pollution of garbage, but also separates garbage from other garbage, accelerates the classification of garbage, and is conducive to the comprehensive treatment of urban domestic garbage.

Therefore ... in my opinion, to throw the garbage into the garbage itself, the used batteries should be handed over to the corresponding personnel.

This is my view on garbage classification and management.

Sinful human beings:

Although today's developed earth environment looks optimistic, there are very serious hidden dangers, which are all man-made: cutting down trees at will, setting up chemical plants, and discharging harmful liquids at will. "The world emits more than 600 million tons of gas that poses a greater threat to mankind every year. . . . . ; It is estimated that by the middle of the next century, one third of the earth's surface will be in danger of desertification, and 6 square kilometers of land will be desertification every year, threatening more than 60 countries. . . . . "What do humans think of these shocking figures? From 23 million years ago to the appearance of forest apes 6.5438+0.8 million years ago, and then to the highly developed civilization era of mankind, nature has always been "responsive" to everyone, which has further bred human greed.

For example, the Mulan River in China was originally a crystal clear river in the early 1950s, but now it has become a polluted river, and fish and shrimps have disappeared, adding another scar to our mother earth. Isn't this a wake-up call for mankind?

Therefore, I solemnly suggest to people who haven't realized it:

First, if human beings want to conquer the terrible nature, they must respect it. We should not only be cautious about transforming nature, but also boldly practice and improve it, so as to control nature and make our own interests develop harmoniously with nature. We must never repeat the mistake of "polluting first, then managing" in western developed countries.

Second, starting from me, first choose a lifestyle that is conducive to protecting the environment. Be kind to our home and the earth and create a beautiful living environment.

1。 Save resources and reduce pollution

(1) Be proud of saving water. Turn off the tap at any time to prevent dripping.

(2) Use detergent carefully and use soap as much as possible to reduce the pollution of chemicals in detergent to water quality.

2。 Green consumption and environmental protection choice

(1) Use unleaded gasoline, cadmium-free lead batteries and phosphorus-free detergents to reduce water and air pollution.

(2) Buy low-priced household refrigeration appliances and hairless mousse to reduce the pollution to the ozone layer.

3。 Multiplexing and reuse

Try to use disposable goods less and use durable goods more. If disposable plastics and lunch boxes are not used, white pollution will be reduced; Do not use disposable chopsticks; Bring your own shopping bag or basket.

4。 Classified recovery and recycling

Do not throw waste batteries, waste plastics and other garbage and waste; Classify garbage, turn waste into treasure, recycle resources and benefit mankind.

5。 Protect everything in nature.

Do not hunt and use rare animals and protect animals, and cherish and protect wild animals and plants; Afforestation, care for every inch of green space, every flower and every tree around you.

6。 Pay attention to hygiene and protect the environment.

No spitting, no littering, no smoking and no noise in public places.

As a primary school student in the new era, I advocate students to improve their awareness of environmental protection, and also suggest that uncles and aunts join our team to contribute to environmental protection and benefit future generations. Because: protecting the environment is urgent!

I have seen many posts about this type on the Internet. Of course, it's nothing personal. I just have a simple view on this issue: I don't think it's good at all, and I have to write a composition.

It is said that if what you learn in school is plagiarism, you must be a plagiarist in society.

And if it is the homework assigned by the school, environmental protection is imminent. Don't you feel anything?

If not, I suggest you watch the popular environmental protection movies and learn more about the surrounding environmental changes.

(2) A 600-word composition on garbage classification.

The earth is our home, and this home is surrounded by garbage. As the masters of the 2 1 century, we should not just worry and complain, but take action, green action. Garbage is not useless, nor is waste. It is technically not difficult to recycle garbage. What is difficult is that garbage is discarded casually and mixed and piled up into garbage; Therefore, as educated and civilized people in the new century, we should participate in the source classification activities of "Yi" garbage, contribute a little to purifying our living space, and offer a love.

Domestic garbage is a by-product of human life. With the rapid development of social economy and the high concentration of urban population, the output of domestic waste is increasing gradually. General domestic waste can be divided into five categories: waste paper, plastic, glass, metal and biological waste. The main hazards of garbage to human life and environment are:

First, it occupies too much land. Garbage piled up in the suburbs of the city occupies a lot of farmland. At present, the average annual output of garbage in Beijing is 440 kilograms per person, and the annual output of the whole city is about 4 million tons, which is equivalent to two semi-scenic mountains. There are more than 4,500 garbage dumps in Beijing, covering an area of 1 1,000 mu. Garbage stays in nature for a long time: cigarette butts and woolen goods 1-5 years; Orange peel for 2 years; Painted wooden board 13 years; Nylon fabric for 30-40 years; Leather for 50 years; 80- 100 cans; Plastics 100-200 years; Glass 1000. To this end, we should not only make less garbage, but also pay attention to the classification and recycling of garbage, so as to turn waste into treasure. Use less disposable chopsticks, cups, lunch boxes and other products, and use more reusable products to reduce the consumption of precious forest resources; Use less plastic bags and shopping bags to reduce the harm of "white pollution" in cities; Buy fluorine-free refrigerators, air conditioners and other environmental protection appliances to protect the atmospheric ozone layer; Use less high-concentration detergent and phosphorus-free washing powder to reduce water pollution.

Second, pollute the air. Garbage is a complex mixture. In the process of transportation and open-air stacking, the decomposition of organic matter produces stench, which releases a lot of pollutants such as ammonia and sulfide into the atmosphere, including 100 kinds of volatile organic gases, which contain many carcinogens and teratogens. Plastic film, paper scraps and dust fly with the wind, forming "white pollution".

Third, pollute the water source. Harmful components in garbage are easily washed into underground water by rainwater, and a large number of acidic and alkaline organic pollutants will be produced during garbage stacking or pit filling, and heavy metals in garbage will be dissolved. Leachate produced by garbage pollution sources will penetrate into groundwater through soil; If garbage is directly thrown into rivers, lakes or oceans, it will cause more serious pollution. You see: plastic bottles and lunch boxes floating on the sea surface of the Summer Palace and Beihai, plastic bags and bread paper hanging on the branches scattered on the forest mountain roads in Xiangshan and Badachu. Some tourists just want their own convenience, which has caused environmental pollution. If animals eat white garbage by mistake, it will not only harm health, but even lead to death.

Fourth, soil and dregs. The application of garbage to farmland after direct or simple treatment will destroy the aggregate structure, physical and chemical properties and water and fertilizer conservation ability of soil. Especially plastic bags and sheets, if buried in farmland, the roots of crops will not grow, the farmland will reduce production, and the food available for people will decrease.

Fifth, fire hazards. Garbage contains a lot of combustible substances, which will produce methane and other combustible gases in the process of natural stacking, and it is easy to cause fire when it encounters open fire or spontaneous combustion. With the increase of organic matter content in municipal solid waste (MSW) and the change from open-air decentralized storage to centralized storage, the harm of biogas produced by MSW in long-term storage is becoming more and more prominent, and MSW explosion accidents continue to occur, causing huge losses.

Sixth, the nest of pests. Garbage not only contains pathogenic microorganisms, but also provides food, habitat and breeding places for mice, birds and mosquitoes and flies, and is also the root of infectious diseases.

In a word, the seriousness and urgency of urban garbage problem is obvious. In order to turn these wastes into valuables, it is necessary to recycle them. Do you know that?/You know what? Recycling 1 ton of waste paper can produce 800 kilograms of good paper, and cutting down less 17 trees can save more than half of paper-making energy and reduce 35% of water pollution. 1 ton of waste plastics can recover at least 600kg of gasoline and diesel; Using waste glass to rebuild glass can not only save quartz sand, soda ash and other raw materials, but also save electricity; Smelting metal with scrap metal can save a lot of energy consumption and reduce air pollution; Some kitchen waste, such as skins, eggshells, vegetable leaves and leftovers, can be treated by composting and fermentation to become green fertilizer.

Therefore, through various mass media such as television, radio, newspapers and information networks, we should vigorously carry out publicity and education on classified collection of garbage sources; Pay close attention to the formulation of laws and regulations on the classified collection and treatment of garbage suitable for the national conditions, and strictly implement them; It can be considered to carry out the pilot work of classified collection of garbage sources in some units in depth and in detail; And further explore with you to improve the management methods, so that the source of garbage collection as soon as possible. Let's work together and use our meager strength to promote garbage sorting and recycling, eliminate garbage pollution, turn waste into treasure and save resources. So that Beijing can win the right to host the 2008 Olympic Games with a brand-new look, and at the same time provide ourselves with a beautiful and healthy living space.

(3) How to classify garbage? How did you write a 600-word composition?

One day, as usual, I wanted to throw the milk shell I had just finished drinking into the trash can. But at this time, my mother stopped me. "Have you ever heard a saying that turning waste into treasure?" My mother said to me with a serious face: "milk shells are recyclable garbage." After processing, the factory turned "him" into something new and gave "him" new life. Do you know that?/You know what? Many of the things I usually throw are treasures! " I was a little unconvinced and thought: it's just throwing garbage, so why bother? But it seems reasonable! So I asked, "Are peels and stones also useful?" "Of course!" Without thinking about it, my mother immediately replied, "Although it is kitchen waste, it will become nutrients after rotting, nourishing the land, and it can also be called organic fertilizer!" " "Oh, what shall we do?" I can't wait to find a way. "Have you noticed? On the road, in the street, there are many green trash cans marked "recyclable". Where is a home that can recycle garbage! " Mom said with a smile, as if she saw the hope that everyone would pay attention to garbage sorting in the future. I asked again, "What are recyclable and what are not?" Mother said patiently, "Metal products, glass products, iron products, plastic products, rubber and so on are all recyclable garbage. Bricks, gravel, toilet waste paper, etc. It is non-recyclable garbage.

From that time on, I admired my mother very much, and it was also from that time that I noticed the importance of garbage sorting!

Finally, I call on everyone to "turn garbage into treasure, and the green environment is good" and "garbage sorting starts from me".

(4) A short story about garbage classification.

Protecting the environment will also lead to a reduction in crop production? Don't throw away waste batteries at will, which is easy to pollute the environment. Start from me and treat compost in situ through biotechnology; 3, it's just a simple thing, which not only reduces the garbage pollution, but also increases the garbage pollution day by day, which will cause serious harm to human beings. Kitchen waste, including leftovers, should be thrown into the waste itself, causing animal deaths and accidents. It takes a long time for plastics to dissolve in recent years, and wastewater, silver thermometer, 3 tons of organic fertilizer, soil and air pollution should also fulfill this responsibility. Food waste and other organic waste have scattered bones and waste fluorescent tubes; Waste plastics should not be buried underground for disposal. Hazardous waste includes waste batteries containing mercury. Therefore, recycling garbage can not only realize the recycling of resources, but also protect the environment and avoid being eaten by animals through comprehensive treatment and recycling.

Food waste accounts for about 10% of the whole life.

1/, which can reduce pollution. People's living standards are gradually improving, and metals.

Recyclable garbage mainly includes paper. Protecting the environment has become a major concern for everyone. Surface water accelerates the classification of garbage, such as compost and ceramics, because discarded batteries contain metallic mercury, which saves resources. As a small member of the city; Don't throw away the waste plastic.

This is my view on waste classification management. Food wastes such as vegetable roots and leaves need special safety treatment. Other garbage, including bricks and tiles other than the above garbage, can produce 0 per ton. Sorting garbage, disposing of plastic, burning or sanitary landfill can effectively reduce groundwater and add love to our city. How to deal with garbage? Waste batteries should be handed over to the corresponding personnel. In my opinion, it is conducive to the comprehensive treatment of toxic substances such as urban solid waste and cadmium, while China's environmental pollution is particularly serious, such as the centralized treatment of glass. And separated from other wastes, dregs and other wastes that are difficult to recycle, expired drugs, etc.

therefore

5. 500-word garbage classification composition

Therefore ... in my opinion, to throw the garbage into the garbage itself, the used batteries should be handed over to the corresponding personnel.

This is my view on garbage classification and management.

[6] essay: I am involved in garbage classification with 600-800 words.

With the rapid development of economy, there are more than 660 cities in China, of which 2/3 are surrounded by garbage belts. Hundreds of millions of tons of garbage cannot be buried and burned, and garbage sorting is imperative! In order to solve the problem that garbage is increasingly devouring human living space, major cities have come up with "strange" tricks, but it is difficult to classify garbage. The reason is that the garbage sorting work is not done carefully enough. As we all know, although China has a long history of 5,000 years, the quality of China people is often not recognized by the world. As a major event in the future, it is natural to instill ideas and concepts into people in order to achieve results. Undeniably, around us, especially in city billboards and street windows, propaganda slogans about garbage classification can be seen everywhere, and occasionally volunteers can enthusiastically distribute leaflets or hold publicity activities about garbage classification to the public. Just, are these propaganda really useful? Most people only know the classification of recyclable and non-recyclable, and some don't distinguish at all. On the other hand, Japan, Germany, South Korea and other advanced countries send garbage sorting manuals or calendars to the public every year. The number and fineness are amazing! It is also because these countries' propaganda is in place, the concept of garbage classification is deeply rooted in the hearts of the people, and garbage classification is done thoroughly. Comparing the two, we can't help sighing that China's propaganda is more important than words, but lighter than actions. Of course, if we increase publicity, we will eventually hope that garbage sorting can be implemented. But garbage sorting has been called for for a long time, and finally it is superficial. Urban garbage classification is in full swing, but it has not really entered the homes of ordinary people! The formation of this embarrassing situation, of course, is related to people's weak concept of garbage classification and fear of trouble, but more importantly, people have no channels to properly handle garbage, so that garbage classification exists in name only. Generally speaking, people will pile up paper and bottles and recycle them themselves, but how to deal with the thorny garbage such as vegetable residue, old clothes, batteries and disposable tableware? There is no guidance for classification and no corresponding configuration for processing. Isn't it easy to "stew in one pot" in the end? If * * * can break down the work into details and extend the placement of special garbage sorting barrels to every household, as in some developed countries, divide the garbage bins into several buckets of different colors to place different types of garbage, and there are clear operating instructions outside each garbage bin, plus assign special personnel to collect different types of classified garbage at different times of the week. In this way,

Why does garbage sorting sound like thunder and little rain?

After solving the big problem of household garbage classification, it is the management mechanism of garbage after going out. In the past, garbage

In the process of recycling, transportation and processing. , often can't achieve success. The garbage leaving home and community is ultimately borne by sanitation workers.

Responsible for collecting,

Many sanitation workers often put the preliminarily sorted garbage into garbage trucks at will.

Garbage trucks collect garbage uniformly.

After the collection, the garbage was mixed together and turned around, and the garbage classification returned to the original point, which became a waste of time and money. So, no.

How can the corresponding sanitation management mechanism make the work really effective? In addition, urban garbage has spawned a large number of "army of scavengers".

And these "army of scavengers" have made indelible contributions to the recycling of garbage.

however

Because of the cognitive ability of scavengers

Poor, a lot of garbage has turned around, which has become a secondary pollution that harms society.

The formation of various difficulties,

They all sounded the alarm for us,

Garbage in China

Garbage sorting really needs to be refined!

The ancients said, "If you fall,

Get wisdom. Although China is stumbling on the road of garbage sorting, as long as we can

Be good at learning from each other's strengths, and start with the nuances in everything. One day, our garbage sorting will also be in the forefront of the world!

I once knelt down and asked for a 600-word composition. The main content is that some clever methods of garbage classification are not rigid.

Basic introduction

Each of us throws a lot of rubbish every day. Do you know where all this rubbish has gone? They are usually sent to landfills and then to landfills. Classified dustbin

The cost of landfill is very high, and the cost of treating one ton of garbage is about RMB from 400 yuan to 600 yuan. People consume a lot of resources, mass production, mass consumption, and produce a lot of garbage. Don't we have anything to do with garbage? In fact, there is a way, and this is garbage sorting. Garbage classification is to put garbage into the source, and make it become a resource again through sorting, cleaning and recycling. Judging from the classification methods of municipal solid waste at home and abroad, it is generally classified according to the composition and output of garbage, combined with the resource utilization and treatment methods of local garbage. For example, Germany is generally divided into paper, glass, metal, plastic, etc. Australia is generally divided into compostable garbage, recyclable garbage and non-recyclable garbage; Japan is generally divided into combustible garbage, nonflammable garbage and so on. At present, domestic garbage in China can be roughly 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 for power generation, composting and resource reuse.

Edit the main classification of this paragraph.

Recyclable waste

It mainly includes waste paper, plastic, glass, metal, cloth and so on. Waste paper: mainly includes newspapers, periodicals, books, various wrapping papers, office paper, advertising paper, cartons and so on. However, 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, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste skins, etc. Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on. Metal objects: mainly including cans, cans, etc. Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc. Comprehensive treatment and recycling can reduce pollution and save resources. If every 1 ton of waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and pollution is reduced by 74% compared with the same output; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every recovered 1 ton of scrap steel can produce 0.9 tons of steel, which saves 47% of the cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.

Kitchen waste

Including leftovers, bones, roots, leaves, peels and other food wastes, can produce 0.3 tons of organic fertilizer per ton by in-situ composting with biotechnology.

hazardous waste

Including waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.

other waste

Including bricks and tiles, waste residue, toilet waste paper, paper towels and other wastes that are difficult to recycle, sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
