Our national household garbage is divided into four categories, recyclable garbage, food waste, hazardous waste, and other garbage.
Recyclable garbage:
]According to the industry standard of "Classification of Municipal Domestic Waste and its Evaluation Standards", recyclables are waste that is suitable for recovery and recycling and resource utilization. It mainly includes:
1. Paper: paper for writing, packaging paper and other paper products that have not been seriously tarnished. Such as used newspapers, periodicals, books, a variety of wrapping paper, office paper, advertising paper, paper boxes and so on. But note that paper towels and toilet paper are not recyclable because they are too water-soluble.
2. Plastic: waste containers plastic, packaging plastic and other plastic products. For example, a variety of plastic bags, plastic bottles, Styrofoam, disposable plastic lunch boxes tableware, hard plastic, and even buttons.
3. Metal: various categories of waste metal items. Such as cans, tin can boxes, lead skin toothpaste skins, waste batteries and so on.
4. Glass: colored and colorless waste glass products, mainly including a variety of glass bottles, broken glass pieces, mirrors, light bulbs, thermos flasks and so on.
5. Fabrics: old textile clothing and textile products, mainly including waste clothes, tablecloths, washcloths, school bags, shoes, etc.
Kitchen waste:
In a narrow sense, kitchen waste is a kind of organic waste, which refers to the source of raw materials and finished products (cooked food) or residues that are needed for family life and diet. But the broader sense of food waste also includes used chopsticks, food packaging materials, etc.
Food Waste is a kind of organic waste.
1. Dietary leftovers, bones, vegetable roots and leaves, expired food and other food waste.
2. Wastes such as fruit peels, egg shells, shells and so on generated during food processing.
3. Bottles and bags used to contain food should be categorized according to the category.
4. Flowers and plants on the balcony, weeds in the garden, etc.
Hazardous waste:
Toxic and hazardous waste refers to the presence of heavy metals, toxic substances that are harmful to human health, or waste that poses a real hazard or potential hazard to the environment. Generally, hazardous, infectious, flammable and explosive are classified as hazardous waste.
1. Used batteries, fluorescent tubes, light bulbs, mercury thermometers and other items containing heavy metals.
2. Paint buckets, mousse bottles, perfume bottles and other combustible items.
3. Televisions, computers, air conditioners, fans, vacuum cleaners, rice cookers and other home appliances; cell phones, telephones, calculators and other small appliances can be recycled or hazardous waste due to the presence of plastics and heavy metals. This type is also called e-waste.
4. Medical waste such as expired medicines and medical items.
5. Expired or unused cosmetics.
Other garbage:
Including masonry 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.
1. Waste generated from site construction and house renovation.
2. Ceramic pieces, dust, slag and so on.
3. Bathroom waste paper, female physiological products and so on.
4. Corn kernels, nut shells, kernels, etc.
Classification of all garbage
Garbage includes two parts: industrial waste residue and domestic garbage. Industrial waste residue refers to the waste generated during industrial production and processing, mainly including coal research stone, fly ash, steel slag, blast furnace slag, red mud, plastic and petroleum waste. Domestic waste is mainly kitchen waste, waste plastics, waste paper, broken glass, metal products and so on. In the city, due to the increasing population, domestic waste is increasing by 10% per year, constituting a major public nuisance.
Domestic and foreign cities on the classification of domestic garbage: according to the composition of the composition of the garbage, the amount of production, combined with the local garbage resource utilization and treatment methods to be classified. Germany, generally divided into paper, glass, metal, plastic, etc.; Australia, generally divided into compostable garbage, recyclable garbage, non-recyclable garbage; Japan, generally divided into combustible garbage, non-combustible garbage, and so on.
China's domestic waste can generally be divided into four categories: recyclable waste, food waste, hazardous waste and other waste. At present, the commonly used methods of garbage disposal mainly include comprehensive utilization, sanitary landfill, incineration and composting.
1, recyclable waste, including paper, metal, plastic, glass, etc., through comprehensive treatment and recycling, 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 be 0.7 tons of secondary raw materials; each recycled 1 ton of scrap iron and steel can be refined 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.
2, kitchen waste including leftovers, bones, vegetable roots and leaves and other food waste, composted by biotechnology in situ treatment, each ton can produce 0.3 tons of organic fertilizer.
3. Hazardous waste includes waste batteries, waste fluorescent tubes, waste silver thermometers, expired medicines, etc., which require special safety treatment.
4, other garbage including in addition to the above categories of garbage, brick ceramics, slag, bathroom waste paper and other difficult to recycle waste, to take sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
How to classify garbage
1, make full use of media resources to join the popularization of garbage classification and recyclable scientific knowledge of publicity and education. The media has a social responsibility, as the *** also has the ability to use all kinds of media resources, including television, radio, newspapers and magazines, and so on, to effectively carry out a wide range of publicity and popularization of the knowledge of the reuse of garbage resources, how to carry out the classification of garbage categorization knowledge of publicity and education. Many people still can't define the classification of combustible garbage, non-combustible garbage, food waste, and so on.
2, the streets and communities as a unit, the training of publicity personnel, the popularization of scientific knowledge of garbage classification education. Community neighborhoods are the most important gathering place for all types of household residual household waste, including food waste, electronic waste, waste paper, batteries, plastics, etc., and the classification of waste is also the most complicated. For the majority of residents, especially those who are older and live in dispersed communities, the lack of knowledge and improper classification are most concentrated. Some residents have a preference for some news media and TV channels, and media newspapers etc. cannot be fully covered, thus starting from the streets and communities is an important place to address the issue of popularizing the knowledge of garbage sorting, which must be strengthened. It is also possible to learn from the experience of Yokohama, Japan, where it is said that in order to improve the effectiveness of garbage disposal, the classification reaches as many as 10 categories, and in order to help people adapt to the new method of garbage classification, a 27-page explanatory booklet has been issued to the public. It may not be a bad idea for us to take the same approach of distributing a booklet on categorization.
3. In primary and secondary education, increase the content of special knowledge on garbage classification, resource utilization and environmental protection. Garbage classification should start from the children, which is one of the successful experiences of foreign countries, especially Japan. The knowledge of garbage classification, resource utilization and environmental protection in primary and secondary education is the fundamental link to solve the problem of garbage classification and resource utilization. It is understood that environmental education in Japanese elementary school starts with garbage classification. These students back home and in the community is also a very good popularization of the propagandist and supervisor, will be the family and around the people of the knowledge of garbage classification and recycling education, so that the whole community gradually formed a good habit of garbage classification.
What are the categories of garbage classification? Examples
Garbage is divided into two categories: "recyclable" and "non-recyclable".
"Recyclables" are mainly paper, plastic, glass, metal and fabric.
1, waste paper: including newspapers, periodicals, books, all kinds of packaging paper, office paper, advertising paper, packaging cartons, etc., but paper towels and toilet paper due to water solubility is too strong not to be recycled.
2, plastic: including a variety of plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles and so on.
3, glass: including a variety of glass bottles, broken glass pieces, mirrors, light bulbs, thermos gallons and so on.
4, metal objects: mainly including cans, can boxes, toothpaste skins, various types of metal parts.
5, fabrics: including discarded clothes, tablecloths, washcloths, cloth schoolbags, cloth shoes and so on.
Non-recyclables" (both waste) include: cigarette butts, chicken feathers, cinders, paints, pigments, waste batteries, food residues, construction debris and so on.
Expanded Information:
From the domestic and foreign cities on the classification of domestic waste methods, roughly based on the composition of the components of the waste, the amount of waste generated, combined with the local waste of resource utilization and treatment methods to carry out classification.
Such as Germany is generally divided into paper, glass, metal and plastic, etc.; Australia is generally divided into compostable garbage, recyclable garbage, non-recyclable garbage; Japan is generally divided into plastic bottles, recyclable plastics, other plastics, resource garbage, large garbage, combustible garbage, non-combustible garbage, hazardous garbage and so on.
China's garbage disposal mostly adopts sanitary landfill or even simple landfill, occupying tens of thousands of acres of land; and insects and flies fly, sewage overflows, the stench of the sky, seriously polluting the environment.
The waste plastics in the soil will lead to crop yield reduction; abandoned waste plastics are eaten by animals, resulting in animal deaths from time to time. Therefore recycling can also reduce the harm.
The benefits of waste separation are obvious. Garbage is sorted and sent to factories instead of landfills, which saves land, avoids pollution from landfills or incineration, and turns waste into treasure. In this battle between people and garbage, people have turned garbage from an enemy to a friend.
Therefore, the classification and collection of garbage can reduce the amount of garbage disposal and treatment equipment, reduce the cost of treatment, reduce the consumption of land resources, with social, economic and ecological benefits.
Sogou Wikipedia - garbage classification
Classification of garbage?
Garbage classification refers to the general term for a series of activities of classifying garbage for storage, placement and transportation according to certain regulations or standards, so that it can be transformed into public **** resources. The purpose of classification is to improve the resource value and economic value of garbage, and strive to make the best use of it.
Recyclable
The five main categories include paper, plastic, glass, metal and fabric.
Trash classification symbols
Waste paper: mainly includes newspapers, periodicals, books, and all kinds of wrapping paper. However, note that paper towels and toilet paper are not recyclable because they are too water-soluble.
Plastic: all kinds of plastic bags, plastic foam, plastic packaging, disposable plastic lunch boxes tableware, hard plastic, plastic toothbrushes, plastic cups, mineral water bottles and so on.
Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, thermos flasks and so on.
Metallics: mainly include cans, can boxes, etc.
Fabrics: mainly include discarded clothes, tablecloths, washcloths, schoolbags, shoes and so on.
These wastes can reduce pollution and save resources through comprehensive treatment and recycling. 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 be obtained from 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.
Non-recyclable
Kitchen waste
Including leftovers, bones, vegetable roots and leaves, peels and other food waste.
Waste classification catalogue
Composted by biotechnology in-situ treatment, each ton can produce 0.6-0.7 tons of organic fertilizer.
Other garbage
Including masonry ceramics, slag, toilet paper, paper towels and other hard-to-recycle waste and shells, dust and soil in addition to the above categories of garbage. Adopting sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
In fact, the big stick bone because "difficult to corrode" is included in the "other garbage". Corn kernels, nut shells, fruit kernels and chicken bones are kitchen waste.
Toilet paper
Toilet paper and toilet paper dissolve when exposed to water and are not considered recyclable "paper", similar to pottery and cigarette boxes.
Kitchen waste bagging
Commonly used plastic bags, even if they are biodegradable, are far more difficult to corrode than kitchen waste. In addition, plastic bags themselves are recyclable waste. The correct way to do this is to empty the kitchen waste into the trash can, and throw the plastic bag into the "recyclable trash" bin.
Fruit shells
In the classification of garbage, "fruit shells and melon skin" is identified as peanut shells, which is indeed a food waste. Waste cooking oil used at home is also categorized as "kitchen waste".
Dust
Dust is categorized as "other garbage" in the garbage classification, but leaf litter is categorized as "kitchen garbage", which includes flowers in the house.
Toxic and Hazardous Waste
Waste that contains heavy metals or toxic substances that are harmful to human health, or that cause actual or potential harm to the environment. It includes batteries, fluorescent tubes, light bulbs, mercury thermometers, paint buckets, some home appliances, expired medicines, expired cosmetics, and so on. These wastes are generally disposed of using separate recycling or landfills.
Classification of garbage
Workshop garbage is more special, the fourth should be able to write the life of the garbage, such as personal discarded Kleenex, cigarette butts and so on, smokeless workshop except ha, huh!
The method of classification of household waste should be able to four categories can be three categories, this needs to be combined with the local situation.
For example, recyclable, non-recyclable, dangerous goods. It's not easy to distinguish between them.
Should be divided into more detailed: materials (recyclable, such as plastic, glass, metal, etc.), kitchen waste (can be used, landfill or composting), non-recyclable (dirt, etc.), dangerous goods (batteries, medicines, etc.) and so on.
The four classifications should make more sense and are more commonly used.
For the sake of the environment in order to survive, garbage should be taken as early as possible to classify the treatment, and from the source. The level of garbage disposal is also a reflection of the level of development of a country.
The family should try to reduce the production of garbage, discarded scientifically and reasonably classified, classified transportation, classified treatment, and ultimately realize the comprehensive utilization of garbage, to achieve the reduction of capacity, harmless treatment.
All of this, should be carried out for the general mobilization of the whole population, and from elementary school to start the publicity and education.
Otherwise, sooner or later we will be eaten by garbage!
