What can we do to reduce white pollution

White pollution usually refers to the phenomenon that various domestic plastic products are discarded as solid waste after use, which is difficult to degrade and treat, resulting in serious pollution of the urban environment, which is a term for people to pollute the environment by plastic waste. The most important white pollution is waste plastic packaging bags, disposable plastic fast food boxes, etc.

The following measures should be taken:

1. Reduce pollutant emissions. Reform the energy structure, use more non-polluting energy sources (such as solar energy, wind energy, hydropower) and low-pollution energy (such as natural gas), pretreatment of fuels (such as desulfurization before coal burning), and improve combustion technology can reduce emissions. In addition, before the pollutants enter the atmosphere, the use of dust and smoke removal technology, condensation technology, liquid absorption technology, treatment technology, etc. to eliminate some pollutants in the exhaust gas can reduce the number of pollutants entering the atmosphere.

2. Control emissions and make full use of atmospheric self-purification capacity. Different meteorological conditions will have different capacities for pollutants in the atmosphere, and the same amount of pollutants will be discharged, resulting in different concentrations of pollutants. For areas and time periods with strong winds, good ventilation, turbulence and strong convection, the atmospheric diffusion and dilution capacity is strong, and more factory and mining enterprise activities can be accepted.

In areas and time periods of temperature inversion, the diffusion and dilution ability of the atmosphere is weak, and more pollutants cannot be accepted, otherwise it will cause serious air pollution. Therefore, emissions should be effectively controlled in different regions and at different times.

The selection of plant sites, chimney design, urban and industrial zone planning should be reasonable, and the excessive concentration of large emitters should not be caused, and the occurrence of serious local pollution incidents should not be caused.

1. Production. Reducing or limiting production is the first step. Since 1950, the production of virgin plastic has increased 200-fold and has been growing at a rate of 4% per year since 2000.

2. Use. As plastic is becoming more and more synonymous with dirty, yet its benefits are unmatched by other materials, and this is worth remembering. It is lightweight, easy to plasticize and inexpensive, and can prevent external contamination of internal substances.

Not all plastics are enemies, only single-use ones, such as plastic bags, straws, coffee stirrers, plastic bottles, and most food packaging, are the main culprits in this challenge.

40% of plastics are disposable, have a lifespan of one year, and the number in this area is decreasing, which will really make a difference, and suggest a massive change in its design, prompting the majority to be able to be utilized.

3. Garbage collection.

Low waste collection rates and poor sorting are the main problems, and the differences between countries are very large. Industries and policies can play an important role in this. The report argues that poorly managed waste plastic is a "critical problem" because it is more polluting than those managed through controlled waste treatment facilities.

4. Processing. Plastic is not adequate**, and most of it is disposed of by landfills, incineration, or dumping. In 2016, less than 20% of plastic was discarded, as the process was unprofitable and more expensive than otherwise.

In Asia, incineration will expand at a rate of 7% until 2023.

5. It can be the best market.

Improving the cost, technology and quality of materials will help to solve this problem, and the first step is to increase the cost of discharging waste plastics into nature above the cost of being used in its entirety at each stage. Measures should be taken to ensure that the global** world of plastics reflects the real costs to nature and society over their full life cycle.

1. Replace plastic with paperMinimize the use of plastic bags.

2. Degradable plastics are used, which can reduce the harm caused by plastic bags.

3. Stipulate from the lawIt can prevent and control white pollution more effectively.

4. Strengthen publicity and educationLet everyone be accustomed to reducing white pollution.

5. Improve the people's awareness of environmental protection and enhance the quality of the people, which is beneficial for alleviating white pollution.

6. Unify ideological understanding and strengthen managementLet everyone realize that it is our own responsibility to protect this earth together.

Introduction to White Pollution

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.

To prevent and control "white pollution", we must first solve the problem of "visual pollution", so that the city's appearance and landscape can be significantly improved. This is mainly through publicity and education to guide citizens to form good living habits; At the same time, it is necessary to strengthen management in accordance with the law, and promote enterprises and individuals to properly collect and dispose of the waste plastic packaging produced by themselves.

The above content refers to Encyclopedia - White Pollution.

1: Use a cloth bag instead of a plastic bag.

2: Replace materials that are not easy to be oxidized with new plastic materials that are easy to be oxidized and cracked.

3: When putting garbage, put the plastic bag into the easy trash can, do not litter.

4: Reduce the output of plastic products in plastic chemical plants.

5: Improve the quality of plastic products and reduce the amount of people use.

Replace plastic packaging with paper packaging.

To solve the problem of white pollution, we must start from several aspects: reduce the use of unnecessary plastic products, reuse some plastic products, use new degradable plastics, and waste plastics

Replacing plastic bags with cloth bags is to reduce the use of unnecessary plastic products, so it is correct

Reuse plastic bags, meet the requirements, so correct

The use of biodegradable plastic lunch boxes can make the plastic decompose by microorganisms, which can prevent white pollution, so it is correct

**All kinds of waste plastics, in addition to saving resources, can also reduce the white pollution caused by waste plastics, so correct

Therefore, d ,8, to solve the problem of "white pollution", the measures we can take are ( ).

Answer analysis: "white pollution" is an image of waste agricultural plastic film, plastic packaging, fast food boxes and other waste plastics polluting the environment, called Douye Qin is a spine stove, plastic substitution, degradable plastics and prohibition of disposable plastic products can effectively prevent and control "white pollution".

Which of the following methods do you think can be used to prevent and control "White Songqingsan Pollution" ()aUse paper instead of plastic packaging.

b.Biodegradable plastic is used.

c.Single-use plastic products are prohibited.

d.All of the above.

Correct answer: d

<>1. Start with yourself. Do not use slag or try not to use plastic bags.

2. Tell your acquaintances or acquaintances. Use as few plastic bags as possible.

4. Plastic bags that are really unavoidable. Used to make garbage bags. Reduce white contamination as much as possible.

5. Use less or no disposable items. Bring your own chopsticks and spoon. And use handkerchiefs to reduce paper waste.
