plastic bag.

“white pollution” mainly refers to the two negative effects of “visual pollution” and “potential harm” to the environment
visual pollution refers to the damage of plastic waste scattered in the environment to the city appearance and landscape, such as polystyrene foamed plastic tableware scattered in the natural environment, on both sides of railways, rivers and lakes, or ultra-thin plastic bags flying all over the sky or hanging branches. These bring adverse stimulation to people’s vision, which is called “visual pollution”. The people reacted strongly to this
potential hazards refer to the long-term deep-seated environmental problems caused by the difficult degradation of plastic waste after entering the natural environment. Its harm includes the following aspects
⑴ plastic film waste accumulates in a large area of soil for a long time, resulting in soil hardening, affecting the absorption of nutrients and water by crops, resulting in crop yield reduction
⑵ plastic wastes discarded on land or in water are swallowed by animals as food, resulting in death
⑶ plastic waste entering domestic waste is light in weight and large in volume, which is difficult to deal with. If it is buried, it will occupy a lot of land and is not easy to degrade for a long time. Domestic waste mixed with plastics is also not suitable for composting. At present, the strongest reflection in society is “visual pollution”, and most people still lack enough understanding of the “potential harm” of plastic waste to the environment.

white pollution data

publicity: because most urban waste treatment in China is not sanitary landfill or incineration to recover heat energy, but waste is moved and transported from the city to the suburbs for open stacking or shallow burial. In case of strong wind, plastic waste with light weight and large volume, especially ultra-thin plastic bags, flows everywhere with the wind, Flying all over the sky (jokingly known as “film fluttering”) or hanging tree branches or electric corridors), as well as plastic residue films and films spreading in rivers, lakes, drainage and irrigation ditches, It is figuratively likened to the “white pollution” line pole (nicknamed “the national flag”) plus the polystyrene foam utensils discarded on both sides of the railway (known as “white” and the social condemnation.

definition: “white pollution” mainly refers to the “visual pollution” and “potential harm”) caused by the environment. Two negative effects
visual pollution refers to the damage of plastic waste scattered in the environment to the city appearance and landscape, such as polystyrene foamed plastic tableware scattered in the natural environment, on both sides of railways, rivers and lakes, or ultra-thin plastic bags flying all over the sky or hanging branches.

data: according to the statistics of relevant departments, there were nearly 4 million tons of domestic packaging plastics (including self-supporting ones) in 1998, of which 30% of the disposable packaging materials that are difficult to recycle will produce about 1.2 million tons of plastic packaging waste every year; The output of plastic mulching film is more than 400000 tons. Because its waste is mixed with a large amount of sand and soil, it is difficult to recycle. Usually, farmers fish them to the ground and burn them, and the recycling amount is very small; Disposable plastic daily necessities and medical and health supplies are about 400000 tons. Combined with the above, the annual output of plastic waste is more than 2 million tons
in recent ten years, with the rapid development of commodity economy, transportation and tourism, the increase of the number and scale of cities, the generation of urban domestic waste has increased significantly. Plastic waste in the composition of municipal solid waste is also increasing rapidly. About 3-10% by weight and 20-30% by volume
, by 2000, the pollution caused by waste plastics will be about 500
10000 tons. In the next 10 years, the cumulative pollution will reach 35 million ~ 40
million tons, which is an amazing figure
in recent years, China’s economic losses caused by environmental pollution and ecological damage have reached 200 billion yuan per year, including 100 billion yuan of ecological damage ‘
. According to the sampling survey of Beijing, Tianjin and Shanghai, there are 1.8 ~ 2.5 billion plastic
bags, one per capita per day; Annual disposable fast
lunch box 1 5~ 2. 200 million, about 500000 ~ 600000 per day; Agricultural film
about 6.75 million square meters and hundreds of millions of beverage bottles every year. Although the total weight of these products is 50000 ~ 60000 tons throughout the year, which is 7% ~ 10% of the total weight of municipal solid waste (garbage)

⑴ legislation on packaging waste
in 1996, the state promulgated the solid waste treatment law of the people’s Republic of China, which clearly stipulates that disposable plastic packaging materials and products, plastic mulch and other products should be recycled, easy to dispose of or easily dissipated in the natural environment. At present, the State Environmental Protection Administration is drafting the regulations on the implementation of the law on the prevention and control of environmental pollution by solid waste to further refine the principles and provisions related to packaging waste in the solid law. Opinions have been solicited nationwide
Law: it is reported that many cities in China have banned the use of such products. In Beijing, the production and use of plastic bags less than 0.015 mm has been prohibited since January 1, 1998. Xi’an, November 1, 1999. It is strictly prohibited to produce,
sell and use disposable ultra-thin plastic bags with a thickness of less than 0.02 mm in the urban area. Tianjin, since October 1, 2000
the production and use of plastic bags less than 0.025mm are prohibited. Datong has banned the production and use of plastic bags less than 0.025mm since May 1, 2001. At present, there is no relevant ban in Harbin

treatment methods: the treatment of “white pollution” is a social system project. Positive countermeasures should be taken and comprehensive treatment by administrative, scientific, technological and economic means. At present, on the premise of strengthening management, formulating relevant policies and regulations, supporting the development of enterprises and institutions conducive to environmental protection, improving people’s awareness of environmental protection and grasping the correct guidance of public opinion, we should learn from foreign 3r1d, that is, the treatment countermeasures of reduction, recycling, recycling and degradation, and implement multiple methods such as provincial recycling (volume reduction, reduction), re recycling (recycling) and harmless (degradable) Countermeasures and measures for the
combination of prevention and control

saving resources, i.e. volume reduction and reduction, is to reduce or inhibit the production of plastic waste, including less use, can be used, and can be used as little as possible or as little as possible; Or by filling natural organic materials or inorganic materials to reduce the amount of plastic, which can not only save limited resources, but also reduce pollution; Or reduce the consumption of disposable plastic packaging by improving product quality and increasing functions, prolonging service life and multi-purpose; Thinning, that is, on the premise of ensuring the application performance, the product can be lightweight and thin-walled by changing the formula of raw materials and the design of product structure; Volume reduction is to reduce the volume of plastic waste through compaction, dissolution, defoaming and other methods, and develop appropriate packaging to curb excess packaging. In fact, “white pollution” is not the sorrow of plastics, but people’s own sorrow. In fact, the source of “white pollution” is not the material or articles themselves, but people’s behavior and habits

If paper-based disposable lunch boxes are advocated, a large amount of forest resources will be consumed. Moreover, no matter what raw materials are used for papermaking, a large amount of clean water, caustic soda and other chemical raw materials will be consumed, and a large amount of waste liquid will be produced at the same time

before going through rigorous experiments and practical demonstration, it is possible to divert attention from the treatment of “white pollution” and even bring new “variegated pollution”
Others: in recent years, many substitutes have been developed, such as paper, pulp molding, plant fiber, whole starch and other tableware. Although they use natural materials as raw materials and are relatively perishable and degradable, the addition of waterproof and oil repellent increases the decay reduction, and it is difficult to reduce the decomposition, quickly solve and recycle, Practice has proved that they still need a certain period to return to nature after use, which is slow and largely depends on environmental conditions

harm: it leads to acid rain, destroys the ozone layer, intensifies the greenhouse effect, and provides a breeding place for mice, mosquitoes, flies and bacteria
most plastic products contain harmful substances such as PVC and acrylonitrile. When they burn, they will produce HCl, which is one of the important reasons for acid rain leads to excessive ultraviolet radiation, exacerbating the greenhouse effect and destroying the ecological balance of the atmosphere. Br>
Plastic waste also releases a variety of toxic chemical gases, such as dioxins

especially dioxin can make people lose weight, liver function disorder, nerve injury and induce cancer
because the residues on waste plastic packaging, such as food residues in fast food boxes and sugar in beverage bottles, will provide a hotbed for mosquitoes, flies and bacteria to survive and reproduce, especially in spring and summer, some common micro organisms such as bacillus, Achromobacter, octococcus and old ball
bacteria can reproduce and grow quickly on plastic packaging stacked or scattered in cities, At the same time, it can also cause a large number of mosquitoes and flies to breed, endanger the health of urban
public and affect environmental sanitation. According to the monitoring around the stacking of solid wastes such as waste plastics
, the total
number of bacteria in air borne microorganisms can reach 8542cfu /m2, and mosquitoes and flies breed in large numbers. Therefore, white pollution should be eliminated for our living environment
spring is a windy season in Tianjin. Plastic bags flying with the wind
can be wound on overhead power supply lines, resulting in short circuit accidents. According to the statistics of the power industry department, in 1996, the power supply network in Tianjin had power outages for more than ten times, causing no less than
due losses to industrial and agricultural production and people’s life.
