2 advocate the garbage classification of people around you
Give advice and suggestions to relevant departments, encourage them to attach importance to garbage sorting and adopt a reward and punishment system.
Study hard and develop a machine that can automatically sort garbage when you grow up ... (no, it's up to you ~)
There will be no standard answer to this question. You should think about it yourself. I'm just giving you some advice. I hope you can adopt them.
Question 2: How do you think garbage should be sorted? 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 and so on. Australia, generally divided into
Garbage, recyclable garbage, 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 and landfill.
.
1. Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth. 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 materials, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, etc. Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on. Metal objects: mainly include cans, cans, toothpaste skins, 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%.
2. Kitchen waste includes food waste such as leftovers, bones, roots and leaves, which are treated locally by biotechnology.
, can produce 0.3 tons of organic fertilizer per ton.
3. Hazardous wastes include waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.
4. Other wastes include bricks and tiles, waste residue, toilet waste paper and other wastes that are difficult to recycle. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
Question 3: What can I do after garbage sorting? The general methods of garbage disposal can be summarized into three methods: material utilization, energy utilization and landfill disposal.
Material utilization, also known as material recycling, refers to physical transformation, chemical transformation (including chemical modification and thermal transformation such as pyrolysis and gasification) and biological transformation (including microbial transformation, insect transformation and animal transformation). ) Reuse, recycle and recycle the material properties of garbage, including the recycling of traditional material resources and the transformation of perishable organic garbage into high-quality material resources.
Energy utilization, also known as energy recovery, refers to converting the internal energy of garbage into heat energy and electric energy, including incineration power generation, heating and cogeneration.
Landfill treatment refers to landfill treatment of useless garbage that cannot be recycled (including material utilization and energy utilization).
From the whole life cycle of garbage, garbage disposal should also include source reduction and emission control. Strictly speaking, reduction refers to source reduction. By changing product design habits, changing raw material purchasing habits, changing consumers' purchasing and consumption habits, and changing business models, we can reduce resource waste and waste generation in the process of production and life. Generally speaking,
Garbage disposal should adhere to the concept of classified and step-by-step utilization of emission reduction at the source, then material utilization, then energy utilization and finally landfill disposal, develop all aspects of garbage disposal in a balanced way, and give full play to the role of various garbage disposal methods, especially to strengthen the material utilization of classified garbage, reduce the amount of garbage generated and reduce the amount of garbage discharged after each level of treatment.
Question 4: What are the benefits of garbage sorting? Save resources; Do not waste; Make the city more beautiful 1 and reduce land occupation: some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 50%.
?
2. Reduce environmental pollution: waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body; Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can reduce the harm. ?
3. Turning waste into treasure: China uses 4 billion plastic snack boxes and 500-700 million instant noodle bowls every year, and waste plastic accounts for 4-7% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. A ton of cans can be melted to form a ton of good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30%-40% of the production waste can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.
Question 5: What are the benefits of garbage sorting? Sorting and collecting garbage 5 points can reduce the amount and equipment of garbage treatment, reduce the treatment cost and reduce the consumption of land resources, which has social, economic and ecological benefits. The advantages of garbage sorting treatment are as follows:
Reduce land occupation
Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.
Reduce environmental pollution
Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body. Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can reduce the harm. ?
turn waste into treasure
China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls and billions of disposable chopsticks every year, accounting for 8- 15% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. A ton of cans can be melted to form a ton of good aluminum blocks, and 20 tons of aluminum ore can be mined less. 30%-40% of the production waste can be recycled, so we should cherish this small-scale and large-scale resource. You can also use cans as pencil boxes, which is environmentally friendly and saves resources.
Question 6: What's the use of garbage sorting? 1 contributes to the recycling of recyclable garbage; 2. It can better treat highly polluted garbage without pollution or reduce pollution; 3. It has a certain effect on environmental protection; 4. Enhance people's awareness of environmental protection
Question 7: What are the benefits of domestic waste sorting? Garbage sorting can turn more garbage into resources and make full use of it, which is very helpful to the environment.
1. Save resources; Do not waste; Make the city more beautiful 1 and reduce land occupation: some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage classification, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 50%.

Question 8: Are there any innovative and feasible methods for garbage sorting? The emergency rate 100 minute rapid microbial fermentation equipment disposal mode, jointly developed by Tonglu and Chinese Academy of Sciences, is novel in technology, good in fertilizer efficiency and fast in fertilizer production, and is suitable for villages with convenient transportation and large population. The common solar composting method is simple in process and low in operation cost, but slow in fertilizer production, which is suitable for mountainous rural areas with inconvenient transportation.
Organic fertilizer made of organic waste can be directly used in farmland, and ordinary people can see the waste turning into treasure at home, which also greatly improves the enthusiasm of classification. Other garbage that can't be composted is also transported to the garbage transfer station in the previous way, and then transported to the county garbage harmless treatment project for high-temperature incineration, which greatly reduces the transportation cost and harmless treatment cost.
Innovate the incentive mechanism and solve how to persist in long-term effect
Let the people know how to divide it, and there are specific facilities to deal with it separately after dividing it, but how to make the people insist on dividing it for a long time requires innovative mechanisms and more ways. In order to let farmers have an accurate understanding of "garbage is a misplaced resource", organize villagers to visit garbage recycling stations regularly, so that villagers can intuitively feel the results of turning sorted garbage into organic fertilizer, and then pass it on from mouth to mouth, which is more conducive to work advancement. Training courses are also held at different levels to provide targeted training to different groups such as villagers, managers and village cadres. The village also combines its own characteristics to innovate its work ideas, and combines garbage sorting behavior with achievement sharing to improve the enthusiasm of the masses.
For example, Fan Village, yangshan, Hengcun Town, Tonglu County is a new countryside characterized by peach planting, and there are a lot of organic wastes such as discarded fruits. Once the peach season comes, these wastes will become a big burden for the village cleaners. At the same time, there is a great demand for organic fertilizer in the village. In order to sell peaches at a good price, a large amount of organic fertilizer needs to be purchased every year. In 20 12, the village began to implement garbage sorting and resource utilization projects. Each household has two buckets, and the management personnel regularly collect them at home. The garbage classification adopts the integral system, and the organic fertilizer produced is used by the peach cooperative, which is helpful to buy daily necessities. Farmers who get a good share can accumulate points for daily necessities.
"I know all the people in the village. I collect it once a day, and I write down the scores of good people. The method of garbage classification and integral system is very popular in our village. Many people in the village can change several barrels of detergent a year, and everyone is very enthusiastic. " Master Teng, the administrator of Yangshan Village Garbage Resource Utilization Station, said.
There are more than 600 acres of cherries in Shuangxi Village, which is separated from Fancun Village in yangshan by a mountain. Almost every household in the small village grows cherries, and Shuangxi Village also adopts the classification and integral system, but it is not a commodity, but an organic fertilizer that can be used by every household. This way not only improves the enthusiasm of the masses, but also provides a nearby organic fertilizer supply point.
There is also a 3A-level scenic spot, Huanxi Village. The characteristics of garbage sorting in this village are the cadre responsibility system and regular publicity and guidance from door to door. Zhou Zhonglian, director of the village, also compiled a jingle of garbage classification ―― Yellow bucket and blue bucket are clearly marked, party member cadres take the lead, children and women go ahead, and organic fertilizer can be returned to the fields, which is convenient for people to remember and provides a good carrier for publicizing and mobilizing farmers' garbage classification. Huanxi Village also combines garbage classification with the selection of "cleanest households" and the red and black list of courtyard renovation. Next, we plan to post a list of farmers with good garbage classification and implement honor incentives.
Innovating management mode to solve how to turn ecology into actual effect
"In the past, I always felt that doing public welfare undertakings such as environmental protection must cost money. I didn't expect that the work of garbage sorting not only didn't cost money, but also produced many economic benefits. " Bao, secretary of Yangshan Village, Hengcun Town, said.
Yangshan Fancun is the first experimental village to implement garbage sorting and resource utilization. Since the implementation of this work, the outbound garbage has been reduced by about 75 tons every year, the transportation cost of garbage in the village has been greatly reduced, and the workload of cleaning staff in the village has also been reduced.
Yangshan Fancun also linked the long-term operation and management of garbage disposal with the peach cooperative in the village, and implemented an innovative management model. Making about 22 tons of organic fertilizer every year can save the cooperative more than 20 thousand yuan in fertilizer cost, and applying organic fertilizer is also very helpful to peach fruit. At the best price, a peach is not enough to sell 10 yuan. With economic benefits, cooperatives have the ability and motivation to pay the salaries, equipment and electricity bills of managers and reward the necessities of life.
It is understood that in Tonglu County 183 administrative villages, 77 villages have fully carried out this work, and the construction of garbage collection and treatment stations in other administrative villages has also been completed about 90%, and the goal of full coverage will be achieved by the end of this year. According to the rural residents in the county, there are about 1 10000 households with * * * 323,000 people ... >>
Question 9: What is garbage sorting? Hello, I'm glad to answer your questions.
Garbage classification is to classify garbage into different categories at the source according to its different recycling value and pollution degree to the environment, which is beneficial to the recycling and treatment of garbage, and make it become a resource again through classification, removal and recycling.
Garbage is generally divided into three categories, namely, harmful waste, non-recyclable garbage and recyclable garbage. Hazardous wastes include: waste batteries, waste fluorescent tubes, mercury thermometers, waste paints, expired drugs, etc. Non-recyclable garbage refers to garbage that is easily decomposed under natural conditions, including peels, vegetable peels and leftovers. Recyclable garbage includes waste paper, waste plastic, waste metal, waste glass, waste fabric, etc. Among them, waste paper includes newspapers, all kinds of wrapping paper, office paper, advertising paper, large and small cartons and so on. Waste plastics include: all kinds of plastic bags, plastic bottles, plastic packaging, foamed plastics, disposable plastic lunch boxes and tableware, hard plastics, etc. Scrap metal includes: cans, tin cans, lead toothpaste skin, etc. And these different kinds of garbage can't be thrown casually, they all have a fixed "home", harmful waste: red bucket; Non-recyclable garbage yellow bucket; Recyclable garbage: blue bucket.
Garbage sorting can turn more garbage into resources and make full use of it, which is of great help to the environment.
I hope my answer can help you, thank you.
