After taking part in this garbage classification activity, I feel that with the rapid development of the economy and the increasing standard of living of the people, the garbage emissions are increasing day by day, and the pressure on the environment is getting bigger and bigger, especially in schools. Every day is making garbage, such as: all kinds of waste paper, plastic bottles, waste batteries, fruit peelings and so on. The vast majority of these are resources that can be recycled. Since participating in the garbage classification activities, I also feel that garbage classification should be done as follows:
1. Raise awareness of environmental protection and establish the concept of garbage classification.
2. Strengthen publicity and training in each class to popularize the method of garbage classification.
3. Introduce the concept of scripture and strengthen the promotion.
4. Formulate measures and put them in place.
Garbage classification, raise your hand, merit in the present generation, benefit in the autumn. The classification of garbage can greatly reduce the pollution caused by the increase of garbage, save the cost of harmless treatment of garbage, and be conducive to the reuse of resources, as well as to cultivate the awareness of environmental protection.
Popularize the knowledge of garbage classification, improve the environmental protection consciousness of the whole nation, comprehensively promote and implement the perfect garbage classification and disposal policy, and build a green, environmental protection, harmonious and economical home. The first step in the process is to make sure that you are aware of the importance of garbage classification, and that you are aware of the importance of the environment.
2. What are the benefits of garbage classification
The benefits of garbage classification
The benefits of garbage classification are obvious. The benefits of sorting garbage are obvious. Garbage is sent to factories instead of landfills, which saves land, avoids pollution from landfills or incineration, and turns waste into treasure. For example, waste batteries are known as "miniature killers", as we all know that batteries in our lives contain heavy metals such as mercury or cadmium, and if these heavy metals are left in the ground, they can easily enter into the groundwater through the leaching of rainwater, which will cause serious persecution to the water resources and the land. However, waste batteries contain a variety of useful metal minerals, recycling value is very high. Because of the serious harm and special recycling value of waste batteries, many countries strictly prohibit them in the garbage and garbage mixing, Japan's community special yellow barrels, will be button batteries, etc. put separately. Again, such as leftovers lettuce, egg shells and peels, picking a class of kitchen garbage and other biological waste, but they can be used to make good organic fertilizer. Like the locust tree community in this big Nano dream biological waste treatment machine, can be biological waste drying, crushing, made of efficient organic fertilizer. Residents can use it to grow flowers and grass. Vegetables grown with them are safer and healthier than chemically fertilized food, and are quite popular in supermarkets. Biological waste usually accounts for 40% of the total waste, if they can be turned into organic fertilizer, not only to save land for landfills, but also to save vehicles and energy to transport them, but also to prevent them from breeding flies and bacteria.
So, there are many benefits of waste classification.
Introducing environmentally friendly trash cans
Generally speaking, the common environmentally friendly trash cans are divided into green, yellow, and red.
The green one is for recyclable garbage, recyclable garbage: paper, plastic, rubber, metal, glass, etc.
The yellow one is for recyclable garbage.
Yellow for non-recyclable garbage, non-recyclable garbage: mainly kitchen garbage, including fruit peels, vegetable
skins, leftovers, etc.
Red for non-recyclable garbage.
Red put toxic and hazardous waste toxic and hazardous waste: batteries, fluorescent tubes, mercury thermometers,
paint buckets, medicines, cosmetics, etc..

7. A show of hands is a source of sustainable resources
8. Throw away "white pollution" and turn it into "white resources" 9. Form civilized dining habits and reduce kitchen waste 10.
3. Trash Classification Knowledge
Knowledge of Trash Classification
In Germany, it is very important to throw trash. If you throw it in the wrong place, the whole neighborhood may suffer.
In 2002, I studied in Germany, studying for a master's degree in environmental engineering, and I also worked in a garbage recycling company after class, which made me feel the importance of environmental protection to the Germans.
It took me a month to figure out how to dispose of garbage
Germany has the highest recycling rate in Europe, and a very sophisticated waste sorting system.
Household waste can be divided into five categories: organic waste, recyclable packaging, paper, glass products and batteries. Different waste is collected in different garbage cans, and the garbage cans are often placed in different places for ease of collection. One of the first things I did when I found my house in Germany was to ask my neighbors for advice on how to properly throw away trash, and it took me a whole month to fully understand.
The trash cans are rarely open, and are basically designed with a sliding lid. When you throw out the trash, you have to push the lid open, and when you let go, the lid automatically returns to its original position. This has two advantages: one is to prevent rain falling into the box, the dumpster into a water tank. Secondly, it can reduce the odor to escape.
Street garbage cans, cover the plastic bags are generally divided into yellow and blue. The former collects recyclable garbage such as paper packaging, and the latter holds household garbage such as fruit peels.
The kitchen garbage cans are generally required to cover the blue plastic bags, usually leftover food, fruit scraps and so on are thrown here. When the bag is full, tie a knot and carry it to a designated place outside the house, and the cleaners will know how to classify the bag by looking at its color.
Organic waste (food, etc.) is usually incinerated or landfilled in Germany, but landfills have been banned in the EU since 2005. Incineration is less polluting and the heat can be used to generate electricity or heat. Next to the organic waste bins there are usually green bins where unwanted waste paper, newspapers, magazines, books, etc. are thrown away.
It should be noted, however, that cardboard boxes and cartons cannot be thrown in. Because they belong to the recyclable packaging, should be thrown into the special yellow plastic bag. Chinese people who have just arrived in Germany are often unaware of this. These plastic bags with the recycling symbol can be obtained free of charge from the nearest post office or supermarket. Other recyclable packaging such as can shells, plastic boxes, etc. can be put into this bag regardless of the material as long as the recycling logo is printed.
Every supermarket in Germany has a box for collecting used batteries. Glass bottles and jars are thrown into different garbage cans depending on the color. Usually glass bins in groups of three, the box is marked with a conspicuous color sign: brown, green, transparent colorless, reminding you not to throw the wrong.
We won't come back if we do it a second time
The vast majority of the German public is supportive of Germany's cumbersome waste sorting. I have a friend who studied at the University of Dresden, and he said that when he first came to Germany, he lived in a student apartment, and because he didn't have the habit of doing so at home, he mixed his garbage into one piece and threw it out. One day, he saw the dormitory manager wearing gloves to open his discarded garbage bag and re-sort it, which made him very shocked and ashamed.
Fail to follow these rules and trouble will find you. Once, I worked in a garbage collection company, followed my colleagues to a neighborhood, a German colleague opened the yellow plastic bag that indicated recyclable, and found a large ball of moldy flour inside, because the flour was so heavy that it burst the plastic bag and spilled all over the floor, according to the rules, the flour should be put in a blue bag. Soon, the staff will be a warning sheet posted at the door of the district, to the following effect: your neighborhood people littering, made a mistake, now issued the first warning, if the second offense, we will not come back.
Listening to the Germans, once the second time, the garbage recycling company will " *** " to punish the whole district, the district management to spend a lot of energy to coordinate, so we are extra careful.
German cleaning workers wages, generally hourly for 12 euros / hour, a month there are about 3,000 euros, not lower than the office white-collar. (Source/Urban Express)
4. Trash classification
From the domestic and foreign cities on the classification of domestic waste method, roughly according to the composition of the composition of the waste, the amount of production, combined with the local waste of resource utilization and treatment methods to classification. For example, Germany is generally divided into paper, glass, metal, plastic, etc.; Australia is generally divided into compostable garbage, recyclable garbage, non-recyclable garbage; Japan is generally divided into combustible garbage, non-combustible garbage, and so on. Nowadays, domestic garbage in China can be divided into four categories: recyclable garbage, food waste, hazardous garbage and other garbage. At present, the commonly used waste treatment methods are: comprehensive utilization, sanitary landfill, incineration power generation, composting, resource return.
Recyclable garbage
Mainly includes waste paper, plastic, glass, metal and cloth five categories.
Food waste
Includes leftovers, bones, roots and leaves, peels and other food waste
Hazardous waste
Includes waste batteries, waste fluorescent tubes, waste silver thermometers, expired medicines and so on, which require special and safe treatment.
Other garbage
Including brick and tile ceramics, slag, toilet paper, paper towels and other hard-to-recycle waste in addition to the above categories of garbage, taking sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
5. Seek some garbage classification knowledge
Recyclable garbage
Mainly includes waste paper, plastic, glass, metal and cloth five categories. Waste paper: mainly including newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cardboard boxes, etc., but pay attention to the paper towels and toilet paper due to the water solubility is too strong can not be recycled. Plastic: mainly including various plastic bags, plastic packaging, disposable plastic lunch boxes and cutlery, toothbrushes, cups, mineral water bottles, toothpaste skins and so on. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos flasks and so on. Metal objects: mainly cans, can boxes, etc. Fabrics: mainly including discarded clothes, tablecloths, washcloths, schoolbags, shoes, etc. Recycling through comprehensive treatment can reduce pollution and save resources. For example, each recycled 1 ton of waste paper can make good paper 850 kilograms, saving 300 kilograms of wood, than the same amount of production to reduce pollution by 74%; each recycled 1 ton of plastic beverage bottles can get 0.7 tons of secondary raw materials; each recycled 1 ton of scrap iron and steel can be smelted 0.9 tons of steel, smelting with ore to save 47% of the cost of smelting to reduce air pollution by 75%, reducing 97% of the water pollution and solid waste.
Kitchen waste
Including leftovers, bones, vegetable roots and leaves, peels and other food waste, composted by biotechnology in-situ treatment, each ton can produce 0.3 tons of organic fertilizer.
Hazardous waste
Includes waste batteries, waste fluorescent tubes, waste silver thermometers, expired medicines, etc., which require special safe treatment.
Other garbage
Including masonry ceramics, slag, toilet paper, paper towels and other hard-to-recycle waste in addition to the above types of garbage, usually according to the characteristics of the garbage to take the way of incineration or landfill treatment.
6. Information on the classification of their own garbage essay a paragraph of about 50 words
The Earth is our home, and this home is being surrounded by garbage. As the owner, we can not just worry and complain, but to have action, to have . Trash is not, and waste products are not, unusable. Garbage and In the technology is not difficult, the difficulty lies in the waste casually discarded, mixed with the accumulation of garbage; therefore, as an educated civilized people of the new century, we should participate in the "hands up" of the source of garbage sorting activities, in order to purify our living space to do a little dedication, dedication and a piece of love. Is a by-product of human life, with the rapid development of social and economic and highly concentrated, the production is gradually increasing. Generally, it can be divided into five categories: plastic, glass, metal and so on. The main hazards of garbage to human life and the environment are: First, occupying too much land. The garbage piled up in the piles occupies a large amount of farmland. Now the average annual production of garbage per person in Beijing is 440 kilograms, and the city's annual production is about 4 million tons, which is equivalent to two and a half Jingshan. There are more than 4,500 garbage dumps in Beijing, covering more than 10,000 acres of land. Garbage stays in nature for a long time: cigarette butts and wool fabrics for 1-5 years; 2 years; painted wooden boards for 13 years; nylon fabrics for 30-40 years; leather for 50 years; 80-100 years; plastics for 100-200 years; glass for 1,000 Years. For this reason, we should not only create less garbage, but also pay attention to the classification of garbage and recycling. Less , , and other products, more reusable products, reduce the consumption of valuable; less plastic bags, instead of shopping bags, reduce the city "" harm; buy , air conditioning and other environmentally friendly electrical appliances, to protect the atmosphere; less high concentration, the use of, reduce . Second, pollution of air . Garbage is a complex mixture of ingredients. In the transportation and open storage process, the decomposition of malodor, and to the atmosphere to release a large amount of ammonia, etc., which contains organic volatile gases up to more than 100 kinds of these releases contain many carcinogenic, . Plastic film, paper and dust are formed " ". Third, pollution of water bodies. Harmful components in the garbage rainwater into the ground water bodies, in the garbage dumping or pit filling process will also produce a large number of acidic and alkaline, and at the same time will be in the garbage Dissolve out. The waste from these sources can enter groundwater bodies through soil infiltration, and more serious pollution can occur if the waste is disposed of directly into rivers, lakes, or oceans. You see:, the Beihai water floating and, the forest road scattered and tree branches hanging on the plastic bags, bread paper, etc., some tourists just want their own convenience, resulting in . If the animals accidentally eat the white trash will not only hurt the health, and even lead to death. Fourth, the soil Chemical. Garbage directly applied to agricultural land, or only after simple treatment for agricultural land will destroy the soil's granular structure, physical and chemical properties and water retention, fertilizer capacity. Especially plastic bags, if buried in the farmland, the roots of crops can not grow, the farmland will reduce yields, the food available for people to eat will be reduced. Fifth, fire hazards. Garbage contains a large number of combustible materials, in the natural stacking process will produce methane and other combustible gases, or easy to cause fire. Along with the increase in the content of and from the open scattered piles into centralized storage, and in the long-term storage of only a simple cover resulting in the hazards of garbage is increasingly prominent, garbage explosions continue to occur, resulting in significant losses. Sixth, the. Garbage not only contains, but also provides food, shelter and breeding places for rats, birds and other species, and is also a source of infectious diseases. To summarize, the seriousness and urgency of the problem is obvious. In order to get rid of this garbage, it is necessary to recycle and utilize the garbage properly. Did you know that 1 ton of recycled waste can produce 800 tons of good paper? Recycling 1 ton can produce 800 kilograms of good paper, can cut 17 trees, can save more than half of the paper energy, reduce 35%; 1 ton at least 600 kilograms of gasoline and diesel back to the refining; with the waste glass glass, not only can save , and other raw materials, but also save electricity; with the waste metal can save a lot of energy consumption can be reduced; and some of the, eggshells, leaves, leftovers and other kitchen waste, can be fermented and processed into green fertilizer. The kitchen waste such as egg shells, vegetable leaves and leftovers can be fermented and turned into green fertilizers. Therefore, we should vigorously publicize and educate on the source of garbage through TV, radio, newspapers and other mass media; formulate laws and regulations on disposal that suit the national conditions and strictly enforce them; consider carrying out in-depth pilot work on the source of garbage in some units; and further discuss and improve the management methods, so that the source of garbage will be universally carried out as soon as possible. Let's work together to promote, remove, and save resources with our hands. So that Beijing can be a new look to win the right to host the 2008, but also to provide ourselves with a beautiful and healthy living space. I'm looking for something useful, it's a bit long.
