1. What are the tips for garbage sorting?

Benefits of garbage sorting

The benefits of garbage sorting are obvious. After sorting, the garbage is sent to the factory instead of landfill, which not only saves land, but also avoids the pollution caused by landfill or incineration, and can also turn waste into treasure. For example, waste batteries called "mini killers" all contain heavy metals such as mercury or cadmium. If these heavy metals are left underground, they can easily leach into groundwater through rainwater, causing serious persecution to water resources and land. The waste battery contains a variety of useful metal minerals, and its recycling value is very high. It is precisely because of the serious harm and special recycling value of waste batteries that many countries prohibit them from being mixed with garbage. Japanese communities have this kind of yellow bucket, which separates button cell from others. Another example is biological waste such as leftover lettuce and eggshell skin, and kitchen waste such as picked Chinese cabbage leaves, but they can all be used as good organic fertilizers. Like this big nano-dream biological waste processor in Huaibai community, biological waste can be dried and crushed to make efficient organic fertilizer. Residents can use it to grow flowers and grass. Compared with fertilizer food, vegetables grown with them are safe and healthy, and are quite popular in supermarkets. Biological waste usually accounts for 40% of the total waste. If all of them can be turned into organic fertilizers, it can not only save land for landfill, but also save vehicles and energy for transporting them and prevent them from breeding mosquitoes, flies and bacteria.

So garbage sorting has many advantages.

Introduce the environmental protection classified trash can.

Generally speaking, the common environmentally-friendly classified trash cans are divided into green, yellow and red.

Green is used to put recyclable garbage, recyclable garbage: paper, plastic, rubber, metal, glass and so on.

Yellow is non-recyclable garbage, non-recyclable garbage: mainly kitchen garbage, including peels and vegetables.

Skin, leftovers, etc.

Red toxic and hazardous wastes: batteries, fluorescent tubes, mercury thermometers,

Paint bucket, medicine, cosmetics, etc.

Slogans about garbage sorting

1. Garbage sorting has many benefits, and environmental protection depends on you and me. Please find a suitable home for garbage.

3. To turn waste into treasure, classified recycling is indispensable. If everyone has a classified heart, garbage can also be turned into gold. 5. Garbage sorting is easy.

6. If the garbage is divided, the environment will be beautiful.

7. Simple and sustainable sources of resources.

8. Throw away the "white pollution" and turn it into a "white resource". Cultivate civilized dining habits and reduce kitchen waste 10. Garbage children should be separated and live and work in peace.

2. Common sense of garbage classification

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, etc. Australia is generally divided into compostable garbage, recyclable garbage and 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 for power generation, composting and resource reuse.

Recyclable waste

It mainly includes waste paper, plastic, glass, metal, cloth and so on.

kitchen waste

Include food waste such as leftovers, bones, roots, leaves and peels.

hazardous waste

Including waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.

other waste

Including bricks and tiles, waste residue, toilet waste paper, paper towels and other wastes that are difficult to recycle, sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

3. Relevant data of primary school waste classification in Guangzhou.

By the end of 20 12, all primary and secondary schools (kindergartens) in Guangzhou should be included in the implementation area of domestic waste classification. Guangzhou Education System Waste Sorting and Disposal Mobilization Conference was held in Guangzhou No.6 Middle School.

Qu Sentinel, director of the Municipal Education Bureau, said, "Garbage sorting is a protracted war. Schools should give full play to their innovative ability and carry out their own creative waste sorting activities to achieve popularization and penetration. " By the end of 20 12, all primary and secondary schools (kindergartens) in Guangzhou will be included in the implementation area of domestic waste classification, and the domestic waste classification will be fully implemented. The awareness rate of middle school students' domestic waste classification reached 100%, the participation rate reached 100%, and the throwing accuracy was not less than 95%. The awareness rate of students' domestic waste classification is 100%, the participation rate is 95%, and the accuracy of delivery is not less than 90%, so as to strive to radiate the community rate of 80%.

2012165438+1On the morning of October 20th, Guangzhou Mayor Chen Jianhua, Guangzhou Municipal People's Congress Deputy Secretary-General Gu Shiyang, Guangzhou TV Station Director Guan Zhijian and other leaders went to Guangzhou primary school to investigate the school waste sorting activities.

4. Garbage classification information

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 very high, and the cost of treating one ton of garbage is about RMB from 200 yuan to 300 yuan. People consume a lot of resources, mass production and consumption, resulting in a lot of waste.

Don't we have anything to do with 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.

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, etc. Australia is generally divided into compostable garbage, recyclable garbage and 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 composting.

[Edit this paragraph] Main classification 1. Recyclable garbage mainly includes five categories: 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, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste skins, etc. Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles and so on.

Metal objects: mainly including cans, cans, 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% cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.

2. Kitchen waste, including food waste such as leftovers, bones, roots, leaves and peels, can be composted in situ by biotechnology, and 0.3 tons of organic fertilizer can be produced 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, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air. [Edit this paragraph] Classification reasons Most of the garbage disposal methods still stay in the traditional stacking and landfill mode, covering an area of tens of thousands of acres; Moreover, insects and flies fly around, sewage overflows and stinks, which seriously pollutes the environment.

Therefore, classified collection of garbage can reduce the quantity and equipment of garbage disposal, reduce the disposal cost and reduce the consumption of land resources, which has social, economic and ecological benefits. The advantages of garbage sorting treatment are as follows: 1, reducing 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. [Edit this paragraph] Some countries' garbage classification Japan's garbage classification Foreigners who have just arrived in Japan will be deeply impressed by its amazing garbage classification.

At first glance, Japan's garbage classification has the following characteristics. First, fine classification and timely recovery.

The largest category is combustible, nonflammable, resource, coarse and harmful, and it is subdivided into several subprojects, each of which can be subdivided into grandson projects, and so on. Combustible: in short, combustible-but not including plastic, rubber fragments, general leftovers, and some combustible domestic garbage.

Resources: newspapers, books, plastic beverage bottles, glass beverage bottles, nonflammable: discarded small household appliances (electric kettles, tape recorders), clothes, toys, ceramic products and iron containers. Coarse categories: large furniture, large electrical appliances (TV sets, air conditioners), bicycles.

A few years ago, Yokohama further subdivided the garbage classification from the original five categories into ten categories, and distributed a 27-page manual to every citizen, with a total of 5 18 items. Try a few examples: lipstick is flammable, but the lipstick tube used is small metal; The kettle belongs to metal, but 12 inch belongs to small metal, and more than 12 inch belongs to big waste; Socks, if one is combustible, if two are "not worn out, and the left and right feet are matched", are old materials; Ties are also old materials, but only if they are "washed and dried".

However, this is a drop in the bucket compared with Shangsheng Town in Tokushima Prefecture. The town divides the garbage into 44 categories and plans to achieve the goal of "zero garbage" by 2020.

In terms of recycling, some communities have a row of classified garbage bins, while others have no garbage bins. Instead, it is stipulated that specific garbage bags should be placed in specific places at specific times of the week and taken away by special personnel in time. For example, in the port area of Tokyo, combustible garbage is collected every Wednesday and Saturday morning, non-combustible garbage is collected on Monday morning, and resource garbage is collected on Tuesday morning.

Many communities stipulate that garbage should be thrown before 8 am, and some are relaxed until noon, but they are all taken away on the same day to avoid polluting the environment or attracting pests.

This also let us know the harm caused by garbage, let us always remember this sentence "garbage disposal is urgent!" " "The school also invited experts to give lectures, what is the role of garbage recycling and what can be done after recycling.

After this activity, our school immediately implemented garbage sorting. The school distributed several trash cans to each class, including non-recyclable and paper trash cans, and also on the stairs.

After the activity, the students knew the benefits of garbage sorting, so everyone actively participated. This activity really benefited us a lot.
