Garbage classification composition 1000 (1) garbage classification-not a new word. Dongguan produces 1 10,000 tons of garbage every day, and the annual landfill treatment fee is 1 1 10,000 yuan. The earth is our home, and this home is surrounded by garbage. This shocking data always reminds us that if we don't classify the garbage, the earth will be gone!
Usually at home, I often listen to my elders talking about the river behind my uncle's house. My mother was playing with friends when she was a child. At that time, the green water was as clear as a ribbon, and there were many small fish and shrimps in the river, so you could drink them when you were thirsty. Wild flowers and tender grass are planted on both sides of the river, and there is a lush tree every other meter, which is full of vitality. However, now looking around, wild flowers, tender grass and trees are all gone; The river is turbid, and dead fish, dead shrimp and garbage float all over the river. As soon as I entered the river, a stench came to my nose. When people pass by the river, they have to walk with their noses covered. Beautiful rivers have disappeared, because people's living standards have improved and their homes have sanitary facilities. However, those domestic sewage were discharged into the rivers around us, which led to the death of small fish and shrimp. A gust of wind blew, and plastic bags of various colors flew all over the sky; Walking casually on the road, discarded cans and batteries can be seen everywhere. According to my mother, a section of No.5 waste battery can pollute at least one square meter of soil and 600,000 liters of water. If every household discarded a waste battery, wouldn't our land and rivers in China be polluted? At that time, where could I grow something to eat? What kind of water do you drink?
In fact, garbage is just a resource that we put in the wrong place. 1 ton of waste plastics can recover at least 600 kilograms of gasoline and diesel. 1 ton waste paper can regenerate 700 kilograms of good paper, cut down less 17 trees, and reduce water pollution in pulp production. Knowing that garbage still plays such a big role, my mother and I made four trash cans at home, and labeled them recyclable trash cans, kitchen trash cans, harmful trash cans and other trash cans respectively. At the beginning, I carefully put the garbage into the trash can, and then put it into the corresponding big trash can in the community when it is full. But after a while, I began to get tired of this kind of trouble, so I just threw garbage. My mother knew, called me to her and said to me earnestly, "Tingting, you asked me to sort the garbage, and our mother and daughter also made four trash cans by themselves." Why don't you sort the garbage now? If everyone is greedy for temporary convenience and throws rubbish at will, our home, the earth, will become a sea of rubbish! "After listening to my mother, I blushed like a fire. From then on, I never dare to throw garbage casually again. I also organized a garbage sorting team with my neighbor's children, which not only publicized the benefits of garbage sorting, but also collected useless batteries or plastic bags and discarded them at designated recycling points. Adults in the community praised us as good children who protect the environment.
Protect the environment, starting from small things and starting from the side. If garbage is properly classified and put in, it will generate value and become a resource.
Garbage classification composition 1000 (2) 1. Problem: 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, the average annual growth rate of municipal solid waste in China was 8.98% in recent 10 years. China has accumulated 6 billion tons of garbage over the years, occupying about 500 million square meters of land. What is all this domestic garbage? Are there any resources that can be recycled? What is the proportion of available ingredients? How to collect things that can be reused and use them for more scientific treatment?
2. Investigation and reflection: From the perspective of resource regeneration, China is a country with relatively poor resources, but the amount of resources wasted and lost every year is quite large. According to the statistics of the Ministry of Internal Trade, the annual resource loss caused by garbage in China is 25-30 billion yuan. There are dozens of tons of copper wasted by discarded ballpoint pens, hundreds of thousands of tons of zinc lost by discarded batteries, tens of thousands of tons of aluminum lost by toothpaste skins, and countless waste papers! On the surface, garbage is the end of consumption, but for society and human beings, especially in today's society where sustainable development is generally realized, garbage recycling should be paid more and more attention. In the small town where we live, garbage can be seen everywhere on both sides of the street, some wrapped in plastic bags, and some discarded on the ground at will; In the corner of the hospital, I saw some expired drugs, abandoned mercury thermometers piled up with some medicine bottles and infusion sets; In a corner of the factory, abandoned batteries, old machines, circuit boards, broken glass and broken boards piled up into mountains; In the vegetable market, discarded fish and vegetables are piled up on the road at will, and flies are buzzing. A sanitation worker told me that these mountains of garbage were sent to a certain place for landfill or incineration. 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?
Garbage classification: Domestic garbage can be divided into three categories: harmful waste, which mainly refers to waste batteries, fluorescent tubes, mercury thermometers, waste paint barrels, corrosive detergents, hospital garbage, expired drugs and radioactive garbage. Organic garbage-garbage that is easily decomposed under natural conditions, mainly kitchen waste. Such as skin, vegetable skin, leftovers, etc. Inorganic garbage-not only discarded paper, plastic, glass, metal, fabric, etc. It also includes large-scale garbage such as scrapped vehicles, household appliances and furniture, and decoration garbage. Most of the dry garbage can be classified and recycled. "Recyclable garbage" mainly includes five categories: waste paper, plastic, glass, metal and fabric. Examples are as follows: 1 Waste paper includes newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, packaging cartons and so on. But paper towels and toilet paper are too water-soluble to be recycled. 2. Plastics: including all kinds of plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, etc. 3. Glass: including all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc. 4. Metal objects: mainly include cans, cans, toothpaste tubes and various metal parts. 5. Fabric: including discarded clothes, tablecloths, towels, cloth schoolbags, cloth shoes, etc.
Suggestions on recycling: 1, it is necessary to strengthen the propaganda of garbage classification, so that people can fully realize that garbage is a resource and should not be thrown away at will. 2. Set up sorting bins at important locations to sort garbage in time. 3, sanitation workers timely processing classified garbage, make full use of resources.
Garbage Classification Composition 1000 (3) Hey, Grandma, what are you doing? "I threw a piece of watermelon skin into a trash can, and my grandmother immediately picked it up and put it in another trash can." This is called garbage sorting. "Grandma said seriously." Garbage sorting? This is the research topic of other scientists. What does it have to do with you? "I couldn't help laughing when I saw my grandmother's serious appearance." Look, look. Grandma brought a poster of the neighborhood Committee and pointed to the slogan, "This is closely related to everyone!" "I was shocked by my grandmother's words. As a young boy, I should pay more attention to these problems!
I came to the study, quickly turned on the computer, and Baidu sorted the garbage. The result is shocking. "Shanghai's daily garbage output reaches 20,000 tons, and it can be piled into a Jinmao building in 16 days ..." "Grandma, come and see." "Then where did all this rubbish go?" Urged by my curious grandmother, I quickly opened the next link. "Most of the garbage is directly landfilled or burned, and the large landfills include the old port and Cao Lu ..." "Cao Lu" My grandmother and I suddenly looked up and our eyes crossed. That's my hometown, but I spent a carefree childhood there ... I have a picture of a landfill in my mind:
A huge wasteland, countless empty bottles, plastic bags of various colors, a garbage truck lifted the trunk, and suddenly, a truck of garbage turned into a hill. Then, a bulldozer ran over it and leveled the garbage. At this time, the smell of garbage suddenly drifted away. They danced in the wind, like a group of demons, rushing around: people and houses, which can reach far away. ...
"Grandma, didn't I suck a lot of poison gas when I was a child?" "Yes, although there are many trees in the country, the air is really bad. In contrast, Beicai is even worse. Come, you can see Beicai Waste Incineration Plant! " Grandma is really sharp-eyed. She saw the "hardest hit"-Beicai. "These wastes will form dioxins and other substances after burning, which will produce carcinogens!" "Grandma, is it because of this that we need to sort the garbage, find out what can be recycled, reduce the amount of garbage and advocate environmental protection?" "Well, computers, household appliances, and glass can be recycled. Now that technology is developed, there are many things that can be recycled! Garbage sorting can reduce the amount of garbage by at least 20%. " "Grandma, you know so much!"
Now we are living in the new era of 2 1 century, and all kinds of technologies and civilizations have made great progress and breakthroughs, but our environmental problems are getting worse. Serious environmental deterioration and pollution accidents are frequently reported all over the country, which not only brings extremely bad influence to residents' health, but also causes people's reflection. Have you paid attention to the small details of environmental protection around us?
Usually, we don't seem to notice these small details at all. We often throw some domestic garbage at will, including old batteries, recyclable or non-recyclable garbage, into a large trash can, ignoring the colorful sorting trash can next to it. This is really convenient, so we don't have to go to great lengths to sort out the garbage one by one. I don't know why we should try our best to sort garbage.
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. The cost of landfill is high, and the cost of treating one ton of garbage is about RMB from 200 yuan to 300 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, China's urban garbage removal capacity was more than 25 million tons, and in 1996, the transportation fee of urban garbage was 1. 16 yuan/ton, which was four times that of 1979.
At present, another garbage disposal method widely used in western countries is incineration. Although the garbage burned at high temperature will not occupy a lot of land, it not only has high cost, but also increases 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 a waste of resources. We constantly turn the limited earth resources into garbage, bury or burn them. Where will our descendants live?
Can't we do something about the 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.
The benefits of garbage sorting are obvious. The garbage is sorted and sent to the factory instead of landfill, which not only saves land, but also avoids the pollution caused by landfill or incineration.
