My rice worms are amazing! It can corrode plastic bags, so can white pollution be cured?

The reason rice worms are able to corrode plastic bags is because they secrete an enzyme that breaks down plastic. This enzyme breaks down plastic into small molecules that can be digested by rice worms. However, this enzyme does not solve the problem of white pollution.

White pollution refers to the excessive use of plastic products by human beings, resulting in a large amount of plastic waste entering the environment, causing serious pollution to the environment. Solving the problem of white pollution requires a variety of measures, including reducing the use of plastics, promoting degradable plastics, and strengthening waste sorting and disposal.

Among them, the promotion of degradable plastics is an effective solution. Degradable plastics can be decomposed into water and carbon dioxide by microorganisms in the natural environment, and will not cause long-term pollution to the environment. At present, scientists are developing a variety of degradable plastics, which have the advantages of environmental protection and sustainability, and can replace traditional plastic products.

In addition, strengthening the classification and treatment of garbage is also the key to solving the problem of white pollution. Through garbage classification, plastic products can be reused to reduce the generation of plastic waste. At the same time, strengthening garbage disposal can avoid plastic waste from flowing into natural environments such as rivers and oceans, and reduce environmental pollution.

In short, solving the problem of white pollution requires the joint efforts of the whole society, including enterprises, scientific research institutions and the public. Only through the comprehensive application of multiple measures can we effectively reduce the amount of plastic waste and protect our environment.

What should we do in the face of the ubiquitous "white pollution"?

1. Strengthen management - prohibit the use of disposable plastic packaging that is difficult to degrade. The harm of "white pollution" can be mitigated to a certain extent within a certain range.

2. Compulsory utilization - clean waste plastic packaging can be reused, or reused for granulation, oil refining, painting, building materials, etc.

3. Replace plastic with paper - the composition of paper is easy to be decomposed by microorganisms in the soil after discarding, and it is much less harmful than plastic bags.

4. The use of degradable plastics - add a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegradants, etc.) in the production process of plastic packaging products, so that the stability of plastic packaging is reduced, and it is easier to degrade in the natural environment.

5. Formulate legal standards - the rational development and utilization of plastic products should start from a long-term perspective and comprehensive factors to formulate practical application standards for plastic products.

1. Classify and dispose of garbage and advocate the best utilization. In this way, the land for landfilling can be reduced, and the reusable paper and metal can be used for the first time.

2. Specific policies should be introduced to support manufacturers of environmentally friendly tableware.

3. Establish a perfect utilization system. Waste disposal systems, such as closed melting furnaces, can be introduced to allow solid waste to be treated, as far as the economy allows.

Prevention and control of white pollution.

1. We should minimize the use of disposable plastic tableware and paper tableware. Any disposable tableware is not only not good for environmental protection, but also the biggest waste of resources. In our daily lives, we should not rely too much on plastic bags.

In the store, it is completely possible to use one or two plastic bags to classify the goods, and the weight of the goods is completely within the tolerance range of the bag, but some customers insist on taking one or two more bags. Most consumers take supermarket plastic bags home as garbage bags, causing secondary pollution to the environment after discarding. Therefore, we should refuse to use plastic bags to buy groceries or hold food, and use vegetable baskets or cloth bags to avoid disposable use and reduce environmental pollution.

You can use your own stainless steel or plastic lunch box to hold food, which is hygienic and environmentally friendly, and will not cause harm to the body.

2. Waste plastics and recycling them is the fundamental way to solve white pollution. In fact, compared with other materials, plastic has a significant advantage: plastic can be easily used repeatedly.

After waste plastics**, after processing, they can be re-turned into products, and gasoline and diesel can also be produced.

In recent years, in Germany, Japan, the United States and other countries, due to the importance of the best treatment of packaging materials, a virtuous cycle of plastic production, use, and reuse has been realized, and white pollution has been fundamentally eliminated. In our country, the work of waste plastics has started. We should cooperate with the relevant departments to classify the waste, so that the work can be carried out smoothly.

3. Strengthening environmental protection publicity, improving citizens' awareness of environmental protection, and forming a good environmental protection atmosphere in the society are the prerequisites for solving white pollution and other forms of pollution. For example, if you want to waste plastics, you must implement a garbage packaging system, and put different types of garbage in different garbage cans, which requires us to have a high degree of environmental awareness.

1 Start by yourself, don't use or try not to use plastic bags.

2 Tell your acquaintances or acquaintances to use as few plastic bags as possible.

4. Plastic bags are used as garbage bags as a last resort to reduce white pollution as much as possible.

5 Use less or no disposable items, bring your own chopsticks and spoons, and use handkerchiefs to reduce paper waste.

What should we do in the face of the ubiquitous "white pollution"?

The so-called "white pollution" is a figurative term for the phenomenon of waste plastics polluting the environment. In nature, there are almost no microorganisms that can use plastic as nutrients. Plastic waste stays in nature for a long time, even up to 500 years.

Now all walks of life are away from the bridge can not be separated from the plastic, and the cost of substitutes is too high, the cost is also high bending, so it is difficult to ban the burial of branches, the country is advocating degradable plastics, has progressed.

If waste plastics are directly incinerated, it will cause serious secondary pollution to the environment. When plastic is incinerate, it produces not only large amounts of black smoke, but also dioxins, by far the most toxic of all. Dioxins enter the soil and take at least 15 months to gradually decompose, which can harm plants and crops. Dioxins have a serious damaging effect on the liver and brain of animals.

The pollution of the environment by dioxins emitted from incineration garbage has become an extremely sensitive issue of concern to the whole world.

In addition, due to the difficulty of degrading disposable plastic tableware, many cities are now promoting the use of green tableware - paper tableware, the principle is that the composition of paper products, cellulose, can be degraded by microorganisms. However, it is also unwise to replace styrofoam cutlery with paper cutlery. First of all, paper cutlery can also bring visual pollution.

They do not degrade quickly, often not completely within tens of days or even months. Secondly, when making paper and tableware, in addition to the use of straw pulp, rice pulp, but also to add about 1 3 wood pulp, if the full promotion, will inevitably cause a large amount of wood consumption, leading to the aggravation of deforestation. However, China's forest coverage rate is only equivalent to the per capita level of the world's per capita forest area.

Third, pulp making has always been a large consumer of water, energy and pollution. The pulping process requires a lot of water, and China is a country with a shortage of water resources. If the sewage is discharged directly into the river without treatment, it will cause water pollution; Paper cutlery needs to be dried immediately after molding, which requires a lot of energy.

China's energy structure is dominated by coal, which will increase the content of SO2 in the air and cause acid rain.

In fact, it is precisely because plastic bags are difficult to dispose of that they are called white pollution.

Many plastic bags are made of polyvinyl chloride, and if incinerated the gas from incineration can pollute the atmosphere, potentially forming more toxic pollutants such as dioxins due to chlorine content. If it is landfilled, it is difficult to degrade because the composition of the plastic bag is stable, and mixing it in the soil will have a long-term impact on the soil.

I think the fundamental way to reduce white pollution is to reduce the use of plastic bags, carry out advanced utilization, and explore degradable materials with low production costs.

To put it simply, plastic bags are mostly white, which is difficult to be degraded naturally and exists for a long time. Isn't it white if there is more, so it is commonly known as white pollution.

First of all, plastic bags are generally white...

Secondly, plastic bags are difficult to degrade under natural conditions...

Finally it will have an impact on the environment. Soil. Plants and animals are harmful, sometimes fatal.

for when it reaches the ground it decays.
