I will give a five-minute speech on garbage sorting 1.
I'll go first for garbage sorting, and the green campus will share the speech.
Dear colleagues and lovely students,
Good Morning, everyone!
Beautiful spring and beautiful environment bring us a new week. The earth is our beautiful home; Campus is where we sow hope.
However, do you know that in beautiful Shenzhen, nearly 20,000 tons of domestic garbage are generated every day. There are two main ways to deal with garbage: landfill and incineration. The garbage dump responsible for landfill is full of sewage and stinks, what's more, this place can no longer be used as cultivated land. The investment in garbage incineration is staggering, and simply burning garbage will increase the risk of secondary pollution. The contradiction between the rapid growth of garbage and the treatment pressure is increasingly prominent!
As a good teenager in the new era, how to help with garbage disposal? In fact, all kinds of garbage are mixed together to be garbage. When we sort and recycle them properly, they will become treasures. According to relevant data, 30%-40% of so much domestic garbage every day has recycling value.
Some students may have questions: Can recycled garbage really "turn waste into treasure"? Let's take a look at what common garbage looks like after treatment: a meal of waste paper can regenerate 800 kilograms of good paper and save 17 trees. After recycling plastic products such as plastic bottles, they can not only be made into recycled plastic products, but also be processed into fuel oil, from which gasoline and diesel oil can be extracted for use. Do you know that three waste lunch boxes can make a ruler for students? It can be seen that garbage sorting can really turn waste into treasure and turn "garbage" into resources. As long as we throw different kinds of garbage into the designated trash can, we can already help cleaners reduce a lot of processing work, help society reduce huge costs, and also help the earth's home reduce resource consumption. What a good welfare!
Garbage sorting is just a trivial matter for us, but it is a big thing for our family, because it is an important work to improve the utilization rate of resources and a great cause to benefit future generations! As a demonstration school of garbage sorting, our school needs every Universiade student in the middle school attached to China to join the ranks of environmental protection with practical actions. Let's start from ourselves and participate in waste sorting, energy conservation and emission reduction actions; Let's lead the new fashion of the times and contribute to building a conservation-oriented green home!
Garbage classification: I'll give a speech for 5 minutes first. 2
There are more than 6.6 billion people living on the earth, and the number is increasing. Such a huge population leads to less and less land per capita, and drinking water resources are often in short supply. But in today's shortage of materials, one thing is growing rapidly, even exceeding the population growth by several times. This is rubbish.
The birth of garbage is accompanied by the development of mankind. Every day, each of us makes garbage. What should we do with the garbage accumulated day by day? Someone said, "You can bury it." However, burying alone is only a temporary solution, not a permanent cure. Since then, the land where garbage is landfilled has lost all nutrients and become a barren land, and the land resources occupied by such landfills are very wasteful. So what should we do? Someone said, "If you can't bury it, you will burn it, so you can't see it!" However, when burning garbage, the smoke and pungent smell are another kind of pollution, which destroys our atmosphere, so it is not desirable. So what exactly should we do? In fact, garbage is not completely useless waste. As long as it is used and treated properly, garbage can be turned into treasure. The crux of the problem is how to turn waste into treasure. The secret is garbage sorting.
Garbage classification, as its name implies, is to classify garbage. Now we classify garbage into four categories in a more standardized way. Most of the four kinds of garbage can be recycled, turning waste into treasure and benefiting mankind again. Only a small part of garbage can't be completely treated, so it can only be treated by traditional landfill and incineration. What are these four categories? The first category is recyclable garbage, including paper, metal and glass. From the name, we know that this kind of garbage can be reused, as long as it is simply integrated from broken to complete; The second category is kitchen waste, such as food waste such as leftovers, bones, roots and leaves. As long as this kind of garbage is treated by biotechnology, it can be transformed into natural chemical fertilizer to nourish the land; The third category, hazardous waste, includes waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment. After complicated processing procedures, the reusable parts are extracted; The fourth category is other garbage, including garbage other than the above three categories, such as brick and tile ceramics, muck, toilet waste paper and other wastes that are difficult to recycle.
Then how can our children help with the garbage? How to be an environmental defender? First of all, we should know which garbage can be reused, which can't be recycled, and which garbage needs special treatment and special collection. Secondly, we should get into the habit of sorting and throwing garbage. At present, the design of trash can has considered the classified delivery of recyclable and non-recyclable. When children throw them, they should throw them in according to the classification, such as paper into the recyclable half, plastic bags into the non-recyclable half, batteries and thermometers into special storage containers, and they should not be thrown casually. Last but not least, it is necessary to make as little rubbish as possible. As long as we cherish the study paper and make good use of each piece of paper, we can't reuse it before throwing it away; Eraser can't be used before throwing; Cherish toys and books, play hard and turn around carefully; Or there is no food left, and so on. , fundamentally reduce the generation of garbage, then it is the best way to deal with garbage and the best environmental defender.
I believe that each of our classmates will strive to be the best environmental protection guardian, starting with garbage sorting, and make contributions to defending our homeland, our school and our planet.
Garbage classification: I'll give a speech for 5 minutes first.
"Grandma, why do you want to be a garbage sorting volunteer? Dirty, tired and unreasonable. " I stood beside my grandmother, holding her hand and asking. "Yes, Mom, you'd better not go." Dad also advised on the side. "No, the community needs volunteers." Grandma said that and went out to sign up as a volunteer. "alas." I sighed in my heart: grandma is really stubborn when she is old.
On Friday morning, I hurried to school with a bag of garbage. When I passed by the trash can, I looked at the colorful trash can, and my heart was agitated: I have to go to school in time, so throw it in the trash can. Anyway, the volunteer is also my grandmother, and she should not "embarrass" me. Thinking of this, I threw the bag of garbage in my hand directly into the wet trash can. Who knows that just a few steps later, my grandmother stopped me: "Yuanyuan, come here!" " There is a kind smile on her face, which is more gentle against the rising sun. You sort the garbage and throw it away. Plastic bags containing garbage should be thrown into dry trash cans. "I dare not go against my grandmother's words, but I am reluctant in my heart and mutter in my heart: I am going to school.
It was not until the garbage was sorted out that the time was delayed for a few minutes and my hands were a little dirty. Grandma guided me to the nearby faucet to wash my hands. I ran all the way to school that day, panting and stepping on the bell into the classroom. I dare not look at the teacher's stern eyes. I complained to my grandmother in my heart: it's all her fault. I am her granddaughter. How can she be so heartless!
In the evening, I walked on the road covered with golden sunshine. When I passed the stinking garbage can with my schoolbag on my back, I covered my nose and ran away quickly. At this moment, I heard a tired gasp behind me. I looked back and found a small figure there to guide people in the community to sort out the garbage. Ah, that's grandma! Https://wWw.ZuoWen8.CoM/ drew a golden outline for grandma in the sunset composition. I found grandma so thin! Look carefully, the wrinkles on grandma's face are like the rings of an old tree. She still wipes her sweat with a handkerchief from time to time. It's not hot today, and grandma still sweats so much, which shows the hard work of volunteering. At this time, I can't help but pay some respect to my grandmother as a volunteer.
The next day was the weekend, and I went out to play with my friends. It's noon, and the hot sun is burning the earth mercilessly. On my way home, I was surprised to find that the number of volunteers changed from one grandmother to three. Their heads are covered with sweat, their clothes are wet, their hair is tightly attached to their foreheads, and their lips are chapped. They must be too busy to drink water. With the help of volunteers, the people who throw garbage beside the trash can are more and more orderly. I asked my grandmother with some admiration: "Grandma, I really admire you!" " You have to volunteer after all this hard work! Let me do it with you. Grandma smiled and said, "Being a volunteer can contribute to the community." . Grandma is happy and not tired. Moreover, garbage sorting is a very meaningful thing. Correct classification can not only facilitate garbage disposal, but also protect the environment. It can also turn waste into treasure and save resources. Not many people in the community have time to volunteer. I have time to help people in the community. However, my strength alone is not enough, so I called two friends who danced square dance with me. "I heard that, I finally understand why grandma became a volunteer. I saw grandma bring some leaflets on garbage sorting from the neighborhood Committee, and my friends and I distributed them to the neighbors in the community. I also bought some bottles of water for grandma and other volunteers to drink.
As soon as I got home, I said to my parents, "Mom and Dad, I want to be a volunteer, too! Sort out a contribution to community garbage. " Grandma looked at me and smiled with relief.

In the morning, I have breakfast in a snack bar near my home. In the early morning, the small shop was crowded with people rushing to work, some stopped to eat, but most of them used disposable fast food boxes and plastic bags to pack soybean milk buns, and then hurried on. Some even eat while walking. After eating, they took out napkins and wiped their mouths. They habitually throw paper, fast food boxes and plastic bags on the roadside or under trees. Not far away, there are three red, orange and blue trash cans. Why not take a few more steps? I seem to hear the sound of a trash can.
Garbage can be seen everywhere on the road, and people seem to have become accustomed to it. Seeing this scene, I have an unspeakable resentment and helplessness in my heart. The wind blew, and the garbage dancing with the wind floated by with my good mood, and a picture flashed in my mind. Many years later, we live in a sea of garbage and can't help but have a cold war. After breakfast, I picked up the garbage beside me on the road, facing the red, orange and blue trash can, and I didn't know how to put it. At this time, an aunt came over, and I quickly asked, "Aunt, which trash can should I throw these garbage into?" "Throw it casually, it doesn't matter anyway." The harsh answer was disappointing. Looking at my aunt's distant figure, I smiled helplessly. If you can throw it at will, why should you divide it into recyclable garbage and non-recyclable garbage? Why do you want to set up red, orange and blue trash cans?
"Blue barrels can be recycled, orange barrels are other, and red barrels are the most harmful." Just when I was depressed, a series of sweet voices sounded from behind my head. I turned around and a little girl was smiling at me. She explained clearly how to classify garbage, and finally said, "This is what our teacher told me." A word awakens the dreamer. According to the principle of garbage sorting, I put Mengniu's milk boxes and cartons into blue vats, and waste batteries and plastic fast food boxes into red vats. I took a long breath when I watched the garbage find home.

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. So what should we do with these domestic wastes?
If all the rubbish is put into the dustbin and then transported to the landfill as before, it will waste a lot of reusable resources. Let me give you a few examples: every 1 ton of waste paper can be used to make 800 kilograms of paper, which is equivalent to saving 4 cubic meters of wood or cutting down 20 trees with a age of 30 years; 900 kilograms of steel can be extracted per ton of scrap steel, which is equivalent to saving 3 tons of ore; 1 ton of waste glass can produce 20 thousand pieces of flat glass or 500g bottles with the area of basketball court; Processing feed with 6,543,800 tons of waste food can save 360,000 tons of feed grain and produce more than 45,000 tons of pork. 1 ton of waste plastics can recover at least 600 kilograms of gasoline and diesel.
Now, with the gradual reduction of available human resources, people's awareness of environmental protection has gradually increased, and they have really realized the importance and urgency of recycling many things in these garbage.
In recent years, many classified garbage bins have been set up on the streets of Guangzhou. Most people think that the establishment of classified garbage bins is beneficial to environmental protection and waste utilization and should be supported. However, some people think that it is more troublesome and inconvenient to throw garbage like this, and it should be classified by sanitation workers. This raises a question: who will start the work of garbage sorting?
In my opinion, garbage sorting is a good thing and should start from every family! Because, if these garbage are mixed together and transported to sanitation workers for classification, first, the sanitation department does not have so much manpower; Second, if these mixed wastes are not buried immediately, they will ferment and stink, pollute the environment and poison human beings. If every household classifies these domestic wastes in advance, sanitation workers can not only recycle those useful wastes, but also dispose of those useless wastes in time to prevent environmental pollution. In today's society, the importance of domestic waste classification is gradually valued by everyone, and garbage classification has become an important content of building a green community.
