p>

Municipal domestic waste can be divided into "hazardous waste, recyclables, kitchen waste, and other waste". Rural domestic waste can be divided into "hazardous waste, recyclables, perishable waste, and other waste". Encourage qualified places to carry out regular and fixed-point classification of domestic waste, and determine the location, delivery time and release specifications according to local conditions.

2. Some common sense about garbage classification

Judging from the methods of classifying domestic waste in various cities at home and abroad, they are generally based on the composition and production volume of garbage, combined with local garbage Classify resource utilization and processing methods. For example, in Germany, it is generally divided into paper, glass, metal, plastic, etc.; in Australia, it is generally divided into compostable garbage, recyclable garbage, and non-recyclable garbage; in Japan, it is generally divided into combustible garbage, non-burnable garbage, and so on. Today, domestic waste in China can generally be divided into four major categories: recyclable waste, kitchen waste, hazardous waste and other waste. Currently commonly used garbage disposal methods include: comprehensive utilization, sanitary landfill, incineration for power generation, composting, and resource return.

Recyclable garbage

Mainly includes five categories: waste paper, plastic, glass, metal and cloth.

Kitchen waste

Including leftovers, bones, roots, leaves, peels and other food waste

Hazardous waste

Including waste batteries, waste fluorescent tubes, waste mercury thermometers, expired medicines, etc. These wastes require special safe handling.

Other garbage

In addition to the above categories of garbage, including bricks, ceramics, slag, toilet waste paper, paper towels and other difficult-to-recycle waste, hygienic landfilling can be effective Reduce pollution to groundwater, surface water, soil and air.

3. Basic knowledge of waste classification

Today, domestic waste in our country can generally be divided into four major categories: recyclable waste, kitchen waste, hazardous waste and other waste. Currently commonly used garbage disposal methods include: comprehensive utilization, sanitary landfill, incineration for power generation, composting, and resource return.

Recyclable waste mainly includes five categories: waste paper, plastic, glass, metal and cloth. Waste paper mainly includes newspapers, periodicals, books, various packaging papers, office paper, advertising paper, cartons, etc. However, it should be noted that paper towels and toilet paper cannot be recycled because they are too water-soluble. Plastics mainly include various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste wrappers, etc. Glass mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc. Metal objects mainly include cans, cans, etc. Fabrics mainly include discarded clothes, tablecloths, face towels, school bags, shoes, etc.

Kitchen waste includes food waste such as leftovers, bones, roots and leaves, peels, etc., which can be composted on-site through biotechnology and can produce about 0.3 tons of organic fertilizer per ton.

Hazardous waste includes waste batteries, waste fluorescent tubes, waste mercury thermometers, expired medicines, etc. These wastes require special treatment.

Other waste includes bricks, ceramics, slag, toilet paper, paper towels and other waste that are difficult to recycle in addition to the above categories of waste. Sanitary landfill can effectively reduce the impact on groundwater, surface water, Soil and air pollution.

4. Common sense of garbage classification

Currently, the commonly used garbage disposal methods include comprehensive utilization, sanitary landfill, incineration and composting. Various types of garbage treatment methods 020202

Recyclable garbage treatment methods Among them, the main processing and recycling methods of recyclable garbage are: 021. Garbage Regeneration Method After the garbage is classified, the materials that can be directly used are for reuse. Such as: discarded glass, plastic, metal, paper, books, newspapers, wood, cloth, waste oil, etc. 022. Waste incineration power generation method This method is commonly used in countries around the world. It can not only thoroughly disinfect and remove harmful substances, but also turn waste into energy.

3. The garbage composting method is based on the traditional agricultural fertilizer accumulation principle, using organic garbage and microorganisms in the soil to convert the garbage into organic fertilizer for soil improvement. 024. The garbage biodegradation method uses a variety of bacterial flora with multifunctional and high degradability to accelerate the decomposition of organic and inorganic matter in the garbage, turning waste into treasure and making the best use of it. According to different bacterial species, it is divided into two types: anaerobic degradation and oxidative degradation.

5. Questions and answers about garbage classification

Each of us throws out a lot of garbage every day. Do you know where the garbage goes? In some areas with good waste management, most of the waste will be treated harmlessly such as sanitary landfills, incineration, and composting. However, in more places, waste is often simply piled or landfilled, causing odors to spread and polluting the soil. and underground water bodies. The cost of harmless disposal of garbage is very high. Depending on the treatment method, the cost of processing one ton of garbage ranges from about one hundred to several hundred yuan. People consume a lot of resources, produce on a large scale, consume a lot, and produce a lot of garbage.

How to turn harm into benefit, turn waste into treasure, and save energy? There is a way, and this is garbage classification. Garbage classification means classifying garbage at the source, and turning it into resources again through classified transportation and recycling.

Domestic waste in Guangzhou can generally be divided into four categories: recyclable waste, kitchen waste, hazardous waste and other waste. Currently commonly used garbage disposal methods include: comprehensive utilization, sanitary landfill, incineration for power generation, composting, and resource return.

(1) Recyclable garbage: mainly includes five categories: waste paper, plastic, glass, metal and cloth.

1. Waste paper: mainly includes newspapers, periodicals, books, various packaging papers, office paper, advertising paper, cartons, etc. However, it should be noted that paper towels and toilet paper cannot be recycled due to their strong water solubility. Recycle.

2. Plastic: mainly includes various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste wrappers, etc.

3. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc.

4. Metal objects: mainly including cans, cans, etc.

5. Cloth: mainly includes discarded clothes, tablecloths, face towels, school bags, shoes, etc.

Through comprehensive processing and recycling of recyclable waste, pollution can be reduced and resources saved. For example, every ton of waste paper recycled can make 850 kilograms of good paper, save 300 kilograms of wood, and reduce pollution by 74% compared with the same amount of production; every ton of plastic beverage bottles recycled can obtain 0.7 tons of secondary raw materials; every ton of scrap steel recycled can be smelted 0.9 tons of good steel 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: including food waste such as leftovers, bones, roots and leaves, peels, etc. This type of waste is processed and composted on-site through biotechnology, and each ton can produce 0.3 tons of organic waste. fertilizer.

(3) Hazardous waste: including waste batteries, waste fluorescent tubes, waste mercury thermometers, expired medicines, etc. These wastes require special safe treatment to avoid harm to the environment.

(4) Other garbage: In addition to the above categories of garbage, including bricks, ceramics, slag, toilet waste paper, paper towels and other waste that are difficult to recycle, they are usually incinerated or landfilled according to the characteristics of the garbage. way to deal with it.

Guangzhou City officially implemented the "Guangzhou City Interim Regulations on the Classification and Management of Urban Domestic Waste" (referred to as the "Regulations") in April 2011, and the classification of domestic waste finally has rules to follow. The "Regulations" implement the principle of garbage classification of "first easy, then difficult, step-by-step, step-by-step implementation". Food waste is first classified, and then other waste is gradually further subdivided. The regulations also specify the amount of fines. It is understood that if an individual fails to dispose of municipal solid waste according to regulations and refuses to correct after being ordered to do so, he will be fined 50 yuan each time. If an unit fails to classify municipal solid waste according to regulations, A fine of 500 yuan per cubic meter will be imposed.

Campus garbage classification and recycling can significantly reduce the pollution caused by the increase of garbage, save the cost of harmless disposal of garbage, and facilitate the reuse of resources. Last year, our school also purchased additional trash cans with garbage classification signs and carried out garbage classification and recycling activities on campus. Through this series of activities, we can not only save resources, but also cultivate teachers and students' awareness of environmental protection. Let us act together to popularize and promote the knowledge of garbage classification, handle garbage according to the requirements of garbage classification, and build a harmonious, beautiful and conservation-oriented campus.
