Why is plastic considered white pollution?

White pollution is a visual term for the phenomenon of refractory plastic waste (mostly referring to plastic bags) polluting the environment. It refers to the use of polystyrene.

Polypropylene, polyvinyl chloride and other polymer compounds.

All kinds of domestic plastic products are discarded as solid waste after use, and it is difficult to degrade and dispose of them due to random littering, resulting in damage to the environment and serious pollution. The refractory nature of plastic is considered white pollution.

White Pollution**.

White pollution is a unique environmental pollution in China's cities, a large number of discarded plastic products can be seen everywhere in various public places, they come from industry, made by human beings, and finally attributed to nature but are not easy to be absorbed by nature, thus affecting the ecological environment of nature.

After waste plastic packaging enters the environment, it is difficult to degrade, causing long-term and deep-seated ecological and environmental problems. First of all, waste plastic packaging is mixed in the soil, which affects the absorption of nutrients and water by crops, which will lead to a reduction in crop yield. second, waste plastic packaging discarded on land or in water bodies is swallowed by animals as food, resulting in animal death (which is not uncommon in zoos, pastoral areas and oceans); Third, mix in household garbage.

Waste plastic packaging is difficult to dispose of: landfill disposal will occupy land for a long time, and household waste mixed with plastic is not suitable for composting.

The waste plastic processed and sorted out is also difficult to use because the quality cannot be guaranteed.

From the point of view of resource conservationSince plastic products are mainly facing depletion of petroleum resources, they should be as much as possible, but due to the production cost at this stage.

much higher than the direct cost of production in the current market economy.

conditions are difficult to do.

Facing the growing problem of white pollutionPeople hope to find a plastic alternative that can replace the current plastic properties without causing white pollution, and degradable plastics.

This new functional plastic is characterized by degradation due to obvious changes in its chemical structure due to obvious changes in its chemical structure under specific environmental conditions, which is harmful to the natural environment.

Harmless or less harmful. For example, starch-filled plastics contain amylase enzymes that are secreted by microorganisms in the soil in a short period of time.

Rapid decomposition leads to the formation of voids, resulting in the mechanical properties of the film.

At the same time, the self-oxidizing agent added to the formula reacts with the metal salts in the soil to form peroxides.

Make polyethylene. The chain is broken and degraded into small fragments that are easily swallowed by microorganisms, which are absorbed by the natural environment and play a role in improving the soil.

Because plastic does not decompose easily and is very harmful to the soil and the environment, it is considered white pollution.

Because plastic bags are a very decomposed garbage, collectively referred to as white garbage.

Because the plastic usually ends up as white garbage and takes a long time to digest.

Because plastic bags are not easy to be decomposed by the environment, soil water is not allowed.

If it is plastic, he is actually not very simple, so it is white garbage.

White garbage is just a general term, and there is also because many plastic bags are white and transparent.

Because although these plastics are very versatile, they are too polluting.

Because plastic is difficult to degrade, it will cause pollution to the environment.

The reason for this is that it is related to his internal composition.

I think it's because the rain pollution of plastic is very difficult to resolve, so I call it white pollution.

Plastic products have brought a lot of convenience to people's lives, but plastic waste has also brought a lot of trouble to people, and is even called white pollution by people. Due to excessive use and inadequate treatment, it has also caused serious waste of energy and resources and environmental pollution. As we all know, coupled with the large volume of waste styrofoam, the garbage classification channel has not been smooth, etc., the pollution problem caused by it should not be underestimated.

The so-called "white pollution" refers to the pollution of the environment by non-degradable plastic waste that can be seen at any time in urban and rural garbage or scattered everywhere. It mainly includes plastic bags, plastic packaging, disposable polypropylene fast food boxes, plastic tableware cups and plates, as well as electrical filling foam stuffing, plastic beverage bottles, yogurt cups, ice cream crusters, etc.

A brief introduction to other cases of white pollution.

The main white pollution is food packaging, styrofoam filled packaging, fast food boxes, agricultural mulch films, etc. White pollution is unique to China's urban environmental pollution, a large number of discarded plastic products can be seen everywhere in various public places, they come from nature, made by humans, and finally attributed to nature but are not easily absorbed by nature, thus affecting the ecological environment of nature.

From the perspective of resource conservation, because plastic products are mainly facing depleted petroleum resources, they should be as much as possible, but because the production cost of re-production at this stage is much higher than the direct production cost, it is difficult to do so under the current market economy conditions.

Plastic products are now more and more serious, although it brings convenience to people's lives, but also brings harm to people.

Summary. Although we know that plastic pollution exists, we still struggle to get rid of it. Of all the obstacles, a major problem is that plastic is cheap.

They are inexpensive to manufacture, and reused plastic is more expensive than the original counterpart, so many companies believe that it is more economical to make new plastic than to separate and recycle it. Secondly, there are many types of plastics on the market, although the appearance is similar, but the chemical cost may be different, which brings a big problem to the **, if the use of manual ** classification, the cost is higher. The point is, so far, there has not been a material that has been able to completely replace plastic.

Hello dear, I haven't found an item that can completely replace him.

However, now degradable materials are slowly becoming popular.

Plastic waste is white pollution. White pollution is a figurative term for the phenomenon of waste plastic polluting the environment. It refers to the packaging bags, agricultural mulch films, disposable tableware, plastic bottles and other plastic products made of polystyrene, polypropylene, polyvinyl chloride and other polymer compounds that are discarded as solid waste after use, and are difficult to degrade and dispose of due to random littering, causing pollution to the ecological environment and landscape.

As a new type of material, plastic products have the advantages of light weight, waterproof, durable, mature production technology and low cost, and are widely used all over the world and are increasing year by year. The growth rate of plastic packaging materials in the world market is higher than that of other packaging materials, and the average annual growth rate of plastic packaging materials from 1990 to 1995 was .

China is one of the top 10 producers and consumers of plastic products in the world. In 1995, China's plastic output was 5.19 million tons, nearly 6 million tons of imported plastics, and the total plastic consumption in the country that year was about 11 million tons, of which 2.11 million tons of plastic were used for packaging. Most of the plastic used in packaging is discarded in the environment in the form of waste film, plastic bags and styrofoam cutlery.

These waste plastic packaging materials are scattered in urban areas, scenic tourist areas, water bodies, and both sides of roads, which not only affect the landscape and cause visual pollution, but also cause potential harm to the ecological environment because it is difficult to degrade.

1. Use less disposable plastic bags, carry the bag every time you go out, and try to use less disposable plastic bags;

2. Reduce the use of takeaways, takeaway packaging boxes are an important part of white garbage, and reducing the use of disposable lunch boxes can prevent and control white pollution;

3. Carry out publicity activities such as drawing boards and netting to slow down the network, and call on people from all walks of life to contribute to the prevention and control of white pollution, and try to use less or no envy of white polluted items;

4. Strengthen the management of disturbing liquid in industries that produce a large number of waste plastic packaging, and change the phenomenon of no one being responsible, disorderly stacking, and random abandonment;

5. Strengthen the publicity of the harmfulness of white pollution, and guide and educate citizens to consciously prevent and control white pollution.
