Decentralization of waste classification

2.

1. Recyclable

mainly includes waste paper, plastic, glass, metal and cloth

2. Non recyclable

kitchen waste

includes food waste such as leftovers, bones, roots and leaves, fruit peel, etc

0.6 ~ 0.7 tons of organic fertilizer can be proced per ton by in-situ treatment and composting with biotechnology

other wastes

include hard to recycle wastes such as brick and tile ceramics, dregs, toilet waste paper, paper towel, fruit shell and st. Sanitary landfill can effectively rece the pollution of groundwater, surface water, soil and air

in fact, big bone is listed as "other garbage" because it is "hard to corrode". Corn kernel, nut shell, nut and chicken bone are food waste

toilet paper

toilet paper and toilet paper dissolve in water, not recyclable "paper", similar to pottery and cigarette case

food waste bagging

common plastic bags, even biodegradable, are far more difficult to corrode than food waste. In addition, plastic bags themselves are recyclable waste. The correct way is to put the food waste into the garbage can and the plastic bag into the "recyclable garbage" can

shell

in waste classification, the mark of "shell and melon skin" is peanut shell, which really belongs to kitchen waste. The waste cooking oil used at home is also classified as "kitchen garbage"

st

in garbage classification, st belongs to "other garbage", but litter belongs to "kitchen garbage", including flowers in the home

toxic and hazardous waste

contains heavy metals, toxic substances that are harmful to human health, or wastes that cause real or potential harm to the environment. Including batteries, fluorescent tubes, bulbs, mercury thermometers, paint barrels, some home appliances, expired drugs, expired cosmetics, etc. These wastes are generally recycled or landfilled separately

extended data

garbage classification refers to a series of activities of garbage classified storage, classified delivery and classified handling according to certain regulations or standards, so as to transform 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

in the stage of classified storage, garbage belongs to the private goods of the public. After classified by the public, garbage becomes the regional quasi public resources of the community where the public is located. After classified and transported to the garbage concentration point or transfer station, garbage becomes the public resources without exclusion. From the domestic and foreign cities of domestic waste classification methods, generally according to the composition of waste, proction, combined with local waste resource utilization and treatment methods to classify

3.

1. Hazardous waste: mainly including waste batteries (nickel cadmium batteries, mercury oxide batteries, lead-acid batteries, etc.), waste fluorescent tubes (fluorescent tubes, energy-saving lamps, etc.), waste thermometers, waste sphygmomanometers, waste drugs and their packaging materials, waste paint, solvents and their packaging materials, waste pesticides, disinfectants and their packaging materials, waste film and waste photo paper, etc

2. Perishable waste: it mainly includes kitchen waste proced by canteens, hotels and restaurants of relevant units, kitchen waste proced by residents' daily life, vegetable, melon and fruit waste proced by farmers' markets and wholesale markets of agricultural procts, carrion, meat and bone, eggshell, viscera of livestock and poultry procts, etc

Recyclables: mainly include waste paper, waste plastic, waste metal, waste packaging, waste textiles, waste electrical and electronic procts, waste glass, waste paper plastic aluminum composite packaging, etc

4. Other garbage: point out other domestic garbage except for the above categories

5. Kitchen waste (called wet waste in Shanghai) includes food waste such as leftovers, bones, vegetable roots and leaves, peel and so on. 0.6 ~ 0.7 tons of organic fertilizer can be proced per ton by on-site treatment and composting with biotechnology

Recently, the regulations of Shanghai Municipality on the management of domestic waste, which will be implemented on July 1, 2019, has aroused extensive discussion. Some netizens jokingly said that the difficulty of garbage classification is too high. At the thought of a fine of 50-200 yuan, they dare not drink milk tea casually, and they dare not eat takeout casually

when it comes to waste classification, we have to mention neighboring Japan. Japan is a country with strict and relatively mature garbage classification in the world. No matter in public places or in companies and families, garbage classification is needed. How does Japan, which makes waste classification to the extreme, do it

5. With the development of economy and the improvement of people's living standard, the problem of garbage has become increasingly prominent. Two thirds of China's 668 cities are surrounded by garbage. These wastes are too much to be buried and burned, causing a series of serious hazards
garbage is garbage only when it is mixed together. Once it is sorted and recycled, it is a treasure. The so-called "garbage classification" is to classify garbage according to the classification of recyclable and non recyclable. Human beings proce a lot of garbage every day. A lot of garbage will cause environmental pollution if it is not recycled and discarded arbitrarily
as early as 2000, Hangzhou started the first garbage classification. According to the two classification standards of recyclable garbage and non recyclable garbage, the implementation effect is not significant. At present, the classification labels of recyclable garbage and non recyclable garbage can still be seen in the garbage houses of residential areas and the garbage cans on both sides of the street, but few people throw garbage according to this standard
in that garbage sorting, the garbage was sorted and collected, and then mixed together for treatment, which was a failure. In the process of garbage classification, collection, cleaning and transportation, we need to build a complete policy to ensure the operation of garbage classification on the right track
"to learn from the experience of the last time, we hope that this time we can start from the most practical aspects in terms of the hardware of garbage sorting and collection, and in terms of the habits of the citizens." Zhang shukong, director of Hangzhou City Management Office solid waste supervision center, said. The preliminary plan of Hangzhou Urban Management Office also started in March this year. First, eight pilot districts, including zhebao apartment and Jiannan District in Hangzhou, will try out waste classification, and then promote it to 37 pilot districts determined this year; By the end of the year, we will strive to promote waste classification in 40% of the residential areas; Next, it will be spread all over the city
in order to actively cooperate with the recently issued policy of waste classification project, we went deep into some communities in Hangzhou to investigate the current situation of waste classification activities according to the objective phenomenon and reality, and carried out a questionnaire survey on the community people. At the same time, with publicity activities, we encouraged everyone to participate in waste classification activities and deeply realized the significance of waste classification, Build our bright future with our hands. In this survey, we will focus on the situation of waste classification in Xiasha District of Hangzhou. We will design a more detailed questionnaire to investigate the social people such as college students, workers, residents, enterprises and government workers, and make statistics on their understanding of waste classification, whether they support waste classification, and whether they will influence the people around them to actively respond to the call of waste classification, Through the statistics and analysis of these questionnaires, as well as from the relevant government departments to understand the implementation of waste classification system in Hangzhou and the concept of Hangzhou citizens. In addition, we will use our relatives and friends to help us carry out questionnaire survey and local people's garbage sorting habits in different types of cities and regions, and analyze the impact of environment on garbage sorting from different regions and groups. At last, we will make an eye-catching achievement book to show the conclusions we have reached and the scenes we have contacted in the investigation, and put forward our own reasonable suggestions on waste classification.

6. The benefits of waste sorting are obvious. After sorting, the waste is sent to factories instead of landfills, which not only saves land, but also avoids the pollution caused by landfill or incineration, and can turn waste into treasure
the classification of recyclable waste is no stranger to the Chinese who have always been diligent and frugal. You may remember the scenes of recycling waste procts in the 1950s and 1960s: toothpaste skins were collected for recycling, orange peels were used for pharmaceuticals, biological waste was used for composting, waste cloth heads, ink bottles and so on could be reused. The classified garbage not only avoids the pollution of garbage, but also provides raw materials for Instry and agriculture
Coke bottles, plastic bags called white garbage and disposable plastic lunch boxes discarded by us every day belong to polymer organic matter. If they are buried in the ground, they will not rot in 100 or 200 years. They will harden the soil, rece soil fertility, and even make the soil lose the ability to cultivate. In our life, we often throw away all kinds of waste plastics. The waste plastics can also be made into buttons, pen containers and other articles after treatment. Waste plastics are also good raw materials for oil refining. Some people have compared them to & quot; Secondary oil field & quot;. One ton of waste plastics can recycle at least 600 kg of gasoline and diesel
do you know what biological waste is? Biological waste is kitchen waste such as leftovers, lettuce, eggshells, peels, and vegetable leaves. What can these seemingly innocuous wastes do? It turns out that they can be used to make good organic fertilizer. For example, the danamong biological waste processor in huaishu district can dry and crush the biological waste to proce efficient organic fertilizer. Residents can use it to grow flowers and grass

compared with fertilizer food, the vegetables planted by them are safe and healthy, and they are very popular in supermarkets. Biological waste usually accounts for 40% of the total waste. If they can be turned into organic fertilizer, it will not only save land for landfills, but also save vehicles and energy for transporting them, and prevent them from breeding mosquitoes, flies and bacteria. Relevant experts suggested that the government should install biological waste treatment units in all residential areas and build working rooms for biological waste treatment in new residential areas
waste classification is an important part of waste pre-treatment
useful materials, such as paper, plastic, rubber, glass, bottles and cans, metal and waste household appliances, can be separated from the garbage through classified delivery and collection, and recycled and reused to turn waste into treasure. It can not only improve the utilization level of waste resources, but also rece the amount of waste disposal. It is an important way and means to realize waste rection and resource utilization

after the garbage is collected by classification, it is convenient to classify and dispose different types of garbage. For example, compost and ferment organic waste, make organic waste into fertilizer for farmland and greening, landfill inorganic waste without recycling value, and incinerate combustible waste with high calorific value

(1) wet waste (organic waste) is processed into organic fertilizer or organic compound fertilizer in organic waste processing plant for greening or agricultural fertilization

(2) dry waste (inorganic waste) is further classified into recyclable components such as waste paper, waste plastic, waste glass and waste metal in the domestic waste sorting center, and then recycled by the corresponding recycling plant

(3) hazardous waste is sorted at hazardous waste sorting and disposal station, recyclable materials are sent for recycling, and resies are incinerated or safely landfilled.

the songs of garbage sorting are as follows:

1

the big blue bucket can be recycled to turn waste into treasure

the green buckets were used to fill the leftovers and turn them into fertilizer for irrigation

Red trash is the most harmful, and the battery lamp is him

Orange buckets are used for other things, and diapers are used for settling down

5, you take one, I take one, don't litter

you take two, I take two, try to use less plastic bags

No smoking in public places

You take four, I take four, don't write everywhere

you shoot five, I shoot five, a variety of plants to protect water and soil

you shoot six, I shoot six, waste batteries need to be recycled

if you shoot seven, I'll shoot it. Energy conservation should be kept in mind

you shoot eight, I shoot eight, garbage classification depends on everyone

if you take nine, I'll take nine, the flowers will look good

you shoot ten, I shoot ten, environmental protection action should be insisted on

After Shanghai issued laws and regulations to enforce waste classification, Beijing will also promote waste classification legislation. Sun Xinjun, director of the Beijing Municipal Urban Management Commission, said that the revision of the Beijing municipal domestic waste management regulations has been included in the 2018-2020 legislative plan. The newly revised regulations will clarify the responsibility of waste classification not only for units but also for indivials. When will waste classification be implemented in Beijing? How to classify? Let's answer them one by one

when will waste classification be implemented in Beijing

in 2009, Beijing Municipal Party committee and government began to promote waste classification. Sun Xinjun said that at present, Beijing has taken the lead in carrying out waste classification in party and government organs, and has created 100 waste classification demonstration areas in 30% of the streets and towns in the city. In 2019, the coverage rate of the demonstration area will reach 60%, covering more than 200 township streets

in terms of implementation scope, more than 2300 public institutions in the city joined the ranks of compulsory waste classification last year, including schools, hospitals, supermarkets and tourist attractions, which basically covered the areas with concentrated crowd and large amount of waste. This year, we will also improve the routine law enforcement inspection and graally cover the residential areas. If the person in charge of waste classification management does not organize the classification or refuses to rectify the unit whose classification does not meet the requirements, it shall be handed over to the law enforcement department for punishment, and graally establish the "no classification, no collection and transportation" backward force mechanism

how to classify the garbage in Beijing

the current garbage classification method adopted in Beijing is "quartering method", which divides garbage into harmful garbage, recyclable materials, kitchen waste and other garbage. This is not only in line with national requirements, but also the simplest classification method at present

Recyclable materials (blue bucket): recyclable, such as newspapers, mirrors, beverage bottles, cans, used clothes, electronic waste, etc., are recycled by renewable resources enterprises, commonly known as "junk collection"

2. Kitchen waste (green bucket): kitchen waste, such as vegetables, leftovers, plants, etc

3. Other garbage (gray bin): including plastic film, plastic bag, paper towel, big bone, corn kernel, etc

Hazardous waste (red bucket): those harmful to health and environment, such as waste lamps, mercury thermometers, expired drugs, paints, cosmetics, etc., should be treated safely by special methods

Where did the garbage go after sorting

different types of garbage have different treatment methods

at present, in Beijing, after garbage is classified, recyclables are recycled by renewable resources enterprises, plastic bags, paper towels and other garbage are sent to incineration plants for power generation or landfill, while hazardous garbage will be treated safely by special methods

in 2019, Beijing will speed up the commissioning of Asuwei, Miyun and Shunyi phase II waste incineration plants, simultaneously promote the construction of Fangshan comprehensive treatment plant and Haidian construction waste recycling project, and strive to complete the main project by the end of the year. For renewable resources, the planning and layout of sorting facilities will be promoted, and the construction of sorting center will be accelerated

However, garbage classification has been only in the form, most residents do not care about it. Shanghai and other big cities also have people living on garbage sorting, but the residents' habit of sorting and recycling is not deep-rooted. If it were not for the strict supervision and fines, plus the power of science and technology, residents would not abide by the classification regulations. Garbage sorting not only depends on policy constraints, but also needs to start from ecation and habit cultivation. Just as Japan has implemented garbage sorting and recycling since 1980, it has become the best country in the world. The Japanese will consciously classify the garbage, which has become a part of life. Therefore, in the implementation of garbage classification in China, we should carry out more garbage knowledge ecation covering all sectors of society, so that garbage classification and treatment methods become an important part of national quality ecation

it is gratifying that Shanghai is at the forefront of the country and has made a good start in protecting the environment and using resources. However, it is necessary to clarify the context, establish a more perfect system and let people take the initiative to implement it voluntarily

garbage classification has to be improved step by step and needs to be further refined, but it is certainly right to take this first step. Everything is difficult at the beginning, once the garbage classification is done well, it can be said that there are many benefits. Garbage sorting starts with you and me

as an innovative proct with revolutionary significance in the waste classification instry, Mr. cat first proposed the concept of guiding the public to do a good job in waste classification from the source. According to the scale of the community and buildings, we set up and put in a corresponding number of recycling points and intelligent garbage collection stations. The operation mode is very simple, With the help of environmental protection card or mobile phone verification code, citizens can open the entrance of the garbage station and put the garbage into metal, glass, plastic, fabric and other different kinds of boxes. After the introction of Mr. cat intelligent garbage collection station, the participation of residents in the community is very high, and the introction and operation of intelligent devices realize 24-hour unattended intelligent delivery, It not only improves the efficiency of classification and saves the labor cost of classification, but also promotes the citizens to develop good classification habits. It is not only the offline intelligent garbage collection station that protects the living environment of citizens. Mr. cat has also devoted countless efforts to software development

in order to create a better user experience, we have independently developed a full set of software procts for different users and operational needs: users can locate the nearest intelligent recycle bin by using Mr. cat app, and can intelligently identify garbage categories through AR technology; Cat operation and maintenance app can monitor whether the equipment is full, remind and reasonably plan the cleaning and transportation route, rece the cost, improve the collection and transportation efficiency, and realize the interconnection and cooperation of people, vehicles and things; Government departments can also control the operation data of garbage classification in real time through the cat data management center, which is convenient for the whole process supervision and management
