Write a composition by recycling waste.

1. How to write garbage collection One day, my mother and I accidentally saw an open-air garbage dump, which was simply a mountain, and the garbage dumps of all sizes were more than 50 meters high! It tastes bad, too. Recyclable garbage is among them, and the recyclable tank on the side is as clean and empty as a model.

"In the past, garbage was buried in mud when it reached one meter. Now trucks with more garbage are also timid." Everyone on the side is talking about it. Isn't there a garbage reduction day now? Why so many? ! How immoral! I thought angrily: If everyone does this, the beautiful earth will become rubbish everywhere. If 1 ton waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and compared with equivalent production, pollution is reduced by 74%. Based on this calculation, when recycling 1500 tons of waste paper, trees originally used for producing 1200 tons of paper can be prevented from being cut down.

Recyclable domestic metal wastes are mainly cans and tin cans. For every recycled 1 ton can, a good 1 ton aluminum block can be formed after melting, and 20 tons of aluminum ore can be mined less; For every 1 ton of scrap steel recovered, 900 kilograms of good steel can be produced, which saves 47% of the cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste pollution by 97%. Mother Earth is our mother, but human beings hurt her. Let's hold hands and love Mother Earth.

2. Write a short essay of 600 to 800 words without classifying garbage. 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. Write a 500-word composition about garbage classification with geographical knowledge. In our campus, there are three trash cans of different colors. They are-green trash can with recyclable materials, blue trash can with non-recyclable materials and red trash can with hazardous waste. Since the trash can is so clearly divided, the garbage must also be thrown into their designated "home". This classification method is very important, and each of us should learn how to classify.

So, how to classify a large amount of garbage?

In our daily life, we always produce domestic garbage. Waste paper and beverage bottles that you look useless can be recycled. For example, 1 ton of waste paper can generate 0 if it is effectively recycled. With 85 tons of recycled paper, you can cut down 17 fewer trees and save 1 coal. 2 tons, saving 600 degrees of electricity, saving water 100 cubic meter, and reducing a lot of solid waste. Why not take such a beneficial action to turn waste into treasure?

Of course, don't get too excited and throw the recyclable garbage in the wrong "home"-the non-recyclable trash can. This kind of trash can is different from the previous one: it only accepts garbage that cannot be recycled. Such as brick and tile ceramics, muck, toilet waste paper, paper towels and so on. These wastes will eventually be disposed of by incineration or landfill according to their characteristics.

I once read a picture in a newspaper: our earth is full of rubbish, and the earth is crying very sadly. At the bottom of the painting is a line written with a green watercolor pen: Don't let our Mother Earth cry!

Finally, I want to say, I hope everyone will take care of our earth, just as the painting says. Garbage sorting, start with me!

Write a short article about people throwing garbage into the river, no less than 450 words. When you threw us from your house to the trash can, did you ever think that we would be useful one day? Now our family is paid more and more attention by human beings, and people use high-tech means to turn waste into treasure.

Can we not be excited and proud? There are many family members in our family: sister of waste glass, brother of waste plastic, brother of waste paper, sister of waste metal and other brothers and sisters. If we classify and recycle family members and then deal with them scientifically, it will be of great use. Let's talk about waste glass first. She used to be very naughty, doing bad things everywhere, and some people even got tetanus after being stabbed.

But now, after human recycling her, recycling glass can not only save quartz sand, soda ash, feldspar powder, coal and other materials, but also save electricity, reduce energy consumption by 32%, reduce air pollution by 20% and water pollution by 50%. Are you surprised that so much energy has been saved? To tell you the truth, the energy saved by recycling a glass bottle can make the light bulb shine for 4 hours! Let's talk about waste plastic. In the past, man used plastic products and threw them into the ground like garbage, but he slept underground for 100 years and didn't rot, and it floated everywhere with the wind. At this rate, the world is full of white pollution. How do humans survive? So the little brother of waste plastic was covered with "white sanitary balls" everywhere, which made him unable to lift his head. Now, scientists have carried out the secondary development of waste plastic brothers, turning harm into benefit, and developed a new type of thermal insulation insulating brick with low cost, good fire prevention performance and good thermal insulation effect, which is suitable for use in different climatic conditions.

Now, Brother Waste Plastic can not only look up in front of "people", but also become a "waste" star. The role of waste paper elder brother and scrap iron elder sister is greater.

Recycling one ton of waste paper can produce 800 kilograms of high-quality paper. Do you know that?/You know what? The raw material for producing paper is trees.

If 800 kilograms of paper is produced from waste paper, 17 trees can be cut down less and water pollution can be reduced by 35%. Can brother waste paper be recycled? In fact, each brother can recycle waste paper at least twice.

As for the metal sister, it is even more necessary to collect it. Mineral resources are non-renewable resources. It takes thousands of years for her to form under special circumstances, and she can reuse them many times. For example, using aluminum cans and aluminum waste packaging to smelt aluminum consumes 765,438+0% less energy, reduces 95% air pollution and has high purity than using bauxite to extract aluminum.

Me, of course, it's kitchen waste, such as Gu, which piles me up for fermentation and turns me into fertilizer B with toxic side effects, but it's better than ordinary emperors seeing me cover up and fertilize. You see, the people in O are munching = the longer the better, and the stick in X is afraid of being robbed = the greener the stick, the more knots there are.

The ditch where the instrument is covered with fertilizer is not only caused by the lack of Z alkali, but also the residual fertilizer is harmful to human health. Everyone doesn't like to eat V, but farmers like our pure natural and pollution-free fertilizer? How about r? My family members also have their own uses.

In fact, we still have a lot of benefits to mankind. I hope you will not abandon us, use your brains and try to make more contributions to mankind.

On my way to school every day, I always pass a garbage station. Every time I hear the garbage crying on the garbage dump, it is discarded by the owner, and some of them have been discarded in a few days. To this end, they complained to each other.

A pair of old and new leather shoes sobbed and said, "I was bought home by a poor man a few months ago." Since then, I have been doing my best to help my master, and I have been on an expedition to the mall with my master every day, leaving early and returning late, and doing my best. " My master loves me so much that he bathes me every few days and brushes me clean. However, since the owner became rich, he became more and more indifferent to me, bought a pair of brand-name shoes that were dozens of times more expensive than me, and finally left me here. Has he forgotten who followed him every day in those poor days? Who ... "Before I finished, my shoes burst into tears, and I can't go on." Me too! "On the side of the wave shoes also cried," I was bought by the little master not long ago and became a good assistant for the little master to run and jump. "My master regards me as the apple of his eye, but since I have a little damage, my master has begun to abandon me, and my status has plummeted since then. Since my young master bought new shoes, he has thrown me away. However, I can still wear it, I can still take it! "

The notebook also cried: "I ... was bought home by the young master's mother a few days ago as a gift for the young master." At first, the young master couldn't put it down. He takes notes on me every day, which records the ups and downs of his growth. I'm proud, but it doesn't last long. One day, I was accidentally given some ink by the young master. He disliked me and he took me away. " "Meowed-"said the notebook and burst into tears. At this time, the carton that has been silent for a long time also told our companions: We were once packaged by them, and then the brand-new ones were thrown away. Isn't this true? What a pity!

At this time, the cries and insults in the garbage dump are getting higher and higher. They have scolded and cried, and their fate has not changed. After careful consideration, they made a decision and suggested that human beings turn waste into treasure, recycle it, and let them shine again for human beings.

Dude, did you hear that? The sound of garbage is telling us their tragic fate. I sincerely hope that all mankind will act and let the garbage never cry!

6. Write a proposal.

Dear students:

If a friend is in trouble, will you stand by and watch? If a friend is in crisis, will you turn the corner? I think of course you will say, "No!"

Now our human friends-animals, some are on the verge of extinction, and some are drastically reduced. It is hard to imagine that if one day people live in an urban desert without animals and plants, life will wither and colors will disappear. ...

Students, save animals, save mankind, save the earth, and act quickly! Therefore, I would like to make the following suggestions:

1. We primary school students should actively study and publicize the wildlife protection law so that more people can understand and abide by it.

There are many frogs now. Frog, also called frog, is an old friend of mankind, so we should not only eat it, but also tell everyone to love it.

At present, things that hurt birds happen from time to time, making many birds homeless. We should build some nests for birds, let them settle down and make greater contributions to mankind.

If you meet small animals on the road, you should do "three noes": no intimidation, no attack and no capture.

If you find or find precious wild animals, you should report to the neighborhood Committee, school and relevant departments in time.

I think: as long as we consciously abide by the wildlife protection law and consciously safeguard the ecological environment, then our motherland and our future will be more beautiful and rich.

7.800-word garbage classification, writing composition We often see waste paper, plastic packaging, cans, food garbage everywhere, here is a pile of peels, a pile of rotten paper. Some people also lit garbage and smoked black smoke, which made people breathless. Garbage dumps, trash cans, and all kinds of garbage are mixed together. It's hot in summer, the garbage is dirty and smelly, and people are hiding. Can you live a healthy life in such a dirty place?

We must change the bad habit of garbage disposal in our daily life. We can't litter. Recyclable garbage such as food packaging paper, metal and plastic should be put into "recyclable" bins, so that these garbage can be turned into treasure and fully utilized. Garbage sorting has many advantages. If the kitchen waste is classified separately, it can be made into high-quality organic fertilizer, which can be used as fertilizer for crops and reduce the use of chemical fertilizer. Separating the kitchen waste with high moisture content can reduce the incineration of other wastes.

Secondary pollution. Separating harmful substances from garbage can reduce the contents of heavy metals, organic pollutants and pathogenic bacteria in garbage. After garbage sorting, a large amount of garbage is reused, which reduces the amount of garbage finally landfilled and prolongs the service life of landfill.

Life. Improve the recycling ratio of waste products, reduce the demand for raw materials and reduce carbon dioxide emissions.

Therefore, we should pay attention to the classification of garbage. Some waste paper shells and beverage bottles in our life can be collected and sent to the waste recycling station, which is environmentally friendly and can earn a little income.

There will be a lot of rubbish in our life, some of which can be recycled, such as beverage bottles, old newspapers, packaging boxes, old batteries and so on. Some of them can't be recycled, such as cigarette butts, peels and vegetable leaves. Garbage recycling is not only beautifying the environment, but also a major event related to health, and it is also a symbol of urban civilization.

Although we are only primary school students, we can do our bit for Beijing's civilization. Usually, I have a habit. No matter where I finish my drink cans and mineral water bottles, I will stay, and I will never leave them outside. No matter how far it is, I will bring it back and put it in the small recycling bin at home. At home, grandma is in charge of the garbage collection station of the whole family. Every weekend, we put these bottles and cans into a big bag. With my father's help, I flattened the paper box, classified the old newspapers and periodicals into one category, stacked them neatly, and then asked my father to help me tie them up with ropes. I saw my father holding both ends of the rope, stepping on the piled newspapers and waste paper boxes with his feet, and tying them firmly with the rope. Wow! Finally finished! So, we sell these recycled garbage to resource recycling stations. The money for selling junk is my pocket money.

Garbage sorting starts with the little things around us. Let's all take action to jointly build an environmentally friendly and energy-saving living environment.

8. Write a composition on the topic "It's not easy to make money". I hope it can be adopted. Thank you! ! ! ! !

This winter vacation should be happy, but my winter vacation life is not like that. I can describe it in one word, and that is "tired".

That winter vacation, our family demolished the house, and the family was very busy. As a member of the family, I also contributed my strength. From the day of the holiday, my father "ordered" my sister and I to work at home together and wouldn't let us go anywhere. I get up every morning. After breakfast, I have to move bricks and carry mortar. Sometimes when busy a little slower, impatient dad will say impatiently, "Hurry up, hurry up, like prawns, you can't even move a few bricks." Remember to read books every day. Really useless! " Hearing this, I really feel bad. Why do you say that about me? I move bricks up and down every day. Aren't you tired? Besides, I have a cold and cough these days, haven't you seen it? As soon as I stopped, you said to me rudely, "You, you have been hurting here or there all day!" " "

When I think about it later, I can't completely blame my father. He is really not easy! He is an ordinary construction worker. He does these things over and over again every day, whether it is cold or hot, but he never says a word of bitterness or tiredness. Dad is the pillar of the family. He shouldered the burden of his family. I don't know how many times, whether it is hot summer or cold winter, when we were still asleep, my father had already rushed to work with the rising sun. Thought of here, I can't help some remorse. Compared with my father's hard work, what is my tiredness these days? I should not blame my father. Who should I tell him that he is tired? The money my father earned was earned by sweat. I should cherish my father's hard work. Only today did I know how difficult it is to make money and how great my father is. I think it's wrong that my dad earns dozens of dollars a day to support his family, but I'm still so extravagant at ordinary times!

Ah, I finally understand how difficult it is to make money. We should cherish today's life and study hard to repay our parents' kindness.

On Sunday afternoon, after finishing my homework, I was idle and ready to go downstairs to play for a while.

When I went downstairs, I found an uninvited guest on the green lawn-a coke bottle. I thought, "how ugly it is to have one more piece of waste on such a beautiful lawn!" " Might as well throw it in the trash can! "Whatever, pick up the coke bottle, I was just about to throw it into the trash can, and it suddenly occurred to me that the bottle can be recycled. Pick up a few more and sell them together. It not only protects the environment, but also gets pocket money. Isn't it killing two birds with one stone?

So, I took the coke bottle and walked forward to find the next target. Found it, finally found it. I saw a plastic mineral water bottle on the road ahead. I was so happy that I quickly looked around and found that there were quite a few people here. Some people looked at me with contemptuous eyes, as if to say, "How can this little girl pick up garbage?" I'm a little embarrassed. I don't know if I can answer it. Alas, what a dilemma! At this moment, I suddenly thought of a good idea. He kicked the mineral water bottle. The plastic mineral water bottle flew into a corner. I immediately ran over, picked up the mineral water bottle and ran away happily.

On the way, I found two more bottles. At this time, my body is getting hotter and hotter and my lips are getting drier and drier. I thought, "I wish I had a bottle of mineral water now!" " "I can dig out my bag and have no money, so I have to give up the idea. Take the bottle and walk to the waste collection station.

I thought all the way: "will the people at the purchasing station laugh at me?" Will ... "At this time, I have come to the waste collection station. A pungent smell suddenly rushed into my nose. I'll cover my nose quickly. That's better. When I arrived at the purchasing station, I saw mountains of waste everywhere. That terrible smell comes from these mountains. I went to the boss of the waste collection station with four bottles and asked, "Boss, how much are these four bottles?" "Twenty cents." I accepted the precious twenty cents, but I was still a little happy and thought, "It's not easy to earn these twenty cents. Then, isn't it more difficult for mom and dad to earn tens of dollars every day? I must save more money in the future and don't waste another penny. "

This morning, when my mother and I went to the store, I saw a child waving a ping-pong bat in his hand. I remember that my father bought me a ping-pong bat last year, and I didn't keep it well. I broke the bat. As I walked, I thought: If only I could have another table tennis bat. So, I discussed with my mother: "Mom, can I get a table tennis bat by my own labor?" My mother readily agreed and said, "Yes, maybe this will let you know how to cherish and care for what you have."

After I came to the store, I began to do my homework, and suddenly I heard my mother say, "Oh, no, the paper in the store is used up!" " "I quickly put down the pen and volunteered." I'll buy it. "Say that finish, I took the money and hurried to the supermarket. I took the elevator to the third floor, selected a roll of paper and paid for it. After the task was completed, I went back to the store. I dug out a math book from my schoolbag and used it as an account book. Then, I solemnly wrote a line on it: one yuan for paper. Then I asked my mother to sign it. After my mother signed it, I said happily, "I made a dollar, not far from table tennis!" "".After dinner, I hurried to take out the garbage and sweep the floor. As a result, I earned another yuan. I looked at the ledger and made a subtotal. I earn two yuan a day. I thought: at this rate, I will have a table tennis bat sooner or later.

Today is a busy day, which makes me understand how difficult it is for mom and dad to make money. We should save money.

Many people say that garbage is a "dubin" that harms our health and a "bad boy" that destroys the earth. In fact, garbage is just a misplaced resource, and they also have the value of reuse.

Although we have many sanitation workers at present, it is not enough to rely on sanitation workers alone, but also on our consciousness. As long as we consciously throw the garbage into the proper trash can and sort it well, these garbage can be turned into treasure and recycled.

This can not only reduce pollution and protect the environment, but also improve the utilization efficiency of the earth's resources. If we sort the garbage, the environment will be very beautiful.

Do you know that a ton of waste paper is equal to a tree? If everyone directly wastes a ton of paper, how many trees are there enough for us? Recycling a ton of paper is equivalent to saving a tree, so that we can not only provide waste paper for thousands of people in Qian Qian, but also it is no longer a dream that green trees surround our homes and forests are all over the city. So from now on, let's sort the garbage together! There are many kinds of garbage, including recyclable garbage, non-recyclable garbage and toxic harmful waste. Recyclable garbage includes: newspapers, book paper, wrapping paper, office paper, advertising paper, cartons, plastic cups, mineral water bottles, etc. Non-recyclable garbage includes peels, leftovers, flowers and leaves. Hazardous wastes include: batteries, metals, etc.

Each of us has our own family, so the garbage also has its own family. We should put the garbage in a suitable "home". Toxic harmful waste should "live" in the red trash can, recyclable trash can should "live" in the yellow trash can, and green trash can is the home of non-recyclable garbage.

It's not difficult to sort garbage, it's just that we can lift a finger. For our homeland, for our tomorrow, from today on, we will actively participate in garbage sorting, create a beautiful community environment, cooperate with garbage sorting, and strive to be civilized citizens together.

10. Persuade students not to litter. How to write a composition Every morning, the cleaner begins to clean up the rubbish. Citizens neatly pile up their garbage in designated places, and some carefully classify recyclable and non-recyclable garbage bags. Tanghe River was once a polluted river in the urban area. Every time I pass by there, I will smell the stench. My mother said that sewage from many factories has been discharged here. Now we are happy that there are more parks, green trees, flowers and sculpture benches by the river. There are duck cruise ships and speedboats with leather valves in the water. In winter, there are many children skating, and the lively scene makes me linger. Such a wonderful thing certainly needs my mother's explanation: every factory is trying to control sewage discharge. I think: fish must also. The Olympic Games is not far from us, and we are looking forward to it! We should also do something for our green Olympics! Then start with the little things around you: no littering, no spitting, no graffiti, no swearing, no fighting; Plant more trees, spend more grass, keep fit, cultivate fresh air and healthy atmosphere, open a door to success for the Olympic Games and be a qualified citizen. Everyone needs to start from me, from now on, from bit by bit, and trickle into the sea. As long as you persevere, a small step for yourself is a big step for society. Let's take part in the "Welcome to the Tree" activity.
