Now in the promotion of a low-carbon economy in the design industry has also appeared a new term: low carbon designIt's low-carbon design.
Low-carbon design is sustainable design that reduces the number of C-rankings in human life. In other words, environmental protection. China only introduced the "plastic ban" on June 1 this year.
It takes quite a while for one thing to replace another, and now in the popular eco-bag, recyclable eco-bag. It has become a trend, a fashion, a trend, and the design of environmentally friendly bags is a public competition that everyone can participate in, whether it is a designer or an ordinary person. ,,Some louder companies have played the slogan of environmental protection, and it is one of the means of publicity in the form of environmental protection bags, which are also very popular,。。
Alas, pure boredom, just passing by

Plastic in the packaging industry is now irreplaceable, just like the status of oil in energy, it is best to develop degradable plastic bags, and now there are many companies that have begun to produce already, need the guidance and incentives of the first, as well as the support of policies.
Toll bags in supermarkets are just a measure to properly degrade unnecessary usage. If you really scrap the plastic bag industry, it is impossible, and many products will lose a lot during transportation. How many products around us will disappear is a step backwards in the economy, and people who say such things should really look into how many of them have to be packaged in plastic bags.
-
Your opinion is very good, and you need good economic policy. Thin plastic bags are not allowed to be used now.
The state should reward the researchers of degradation, which is to sparse rather than block.
-
It is enough to abolish them directly, the key is a matter of strength, not a problem of system.
-
Another way is to produce less and only give it to the food industry.

The plastic bags commonly used in our lives are called white pollution, how many years does it take for plastic bags to degrade naturally?
White garbage is generally called white pollution, which is the name of the image of waste plastic polluting the environment. Polystyrene, polypropylene, polyvinyl chloride and other polymer compounds made of packaging bags, agricultural mulch films, disposable tableware, plastic bottles and other plastic products are discarded into solid waste, discarded at will, difficult to decompose and process, ecological environment and landscape natural decomposition is the process of decomposing complex organic substances such as wood, paper, animal carcasses into simple small molecule organic compounds. Usually, after organic matter is buried in the soil, it can be broken down by microorganisms such as bacteria, fungi, etc. in the soil.
The decomposed organic matter can be used for the recycling of microorganisms and plants, providing food for plants**, enriching soil nutrients, and indirectly feeding other organisms.
The problem with plastics, gloves, masks that don't break down naturally quickly and naturally is that their ingredients are not organic. For example, most of the plastics currently in use are made from polyethylene terephthalate, which most bacteria can't decompose, so it's almost impossible for microorganisms to break down. Ultraviolet rays from sunlight destroy the structure of plastic and promote decomposition, but this process is slow and takes a long time.
Currently, new biodegradable plastics are being developed. For example, plant starch is used as a raw material and processed into biodegradable plastics through chemical modification. It is hoped that one day, biodegradable plastics can fully replace refractory plastic products.
Of course, there are also many ways to reduce the use of plastic, such as using reusable bags when shopping or refusing to use plastic bags.
Most of the white garbage is combustible, and methane and other gases are produced in the process of stacking natural substances, and fire accidents such as fires and spontaneous combustion occur constantly, often causing heavy losses. Increases the risk of infection with the disease. White trash can become a nest for pests, providing food, habitat and breeding for rats, birds, mosquitoes, and its residue is often the source of infectious diseases.
Not easy to decompose. After the waste plastic packaging enters the environment, it is difficult to decompose, causing long-term and profound 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, resulting in reduced crop yields. Secondly, livestock eating plastic film can cause digestive diseases and even death in livestock.
-
If plastic bags are completely degraded naturally, it will take decades or even hundreds of years, so we must use less plastic bags in our lives to reduce white pollution.
-
It takes 200 years for plastic bags to degrade naturally, and some even take more than 1,000 years to degrade.
-
It will take at least 50 years. This kind of pollution is simply too bad, and plastic bags are very difficult to degrade. It puts a lot of pressure on the environment.

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.

White pollution is an image of the phenomenon of waste plastic polluting the environment, which refers to the use of polystyrene, polypropylene, polyvinyl chloride and other polymer compounds made of packaging bags, agricultural mulch film, disposable tableware, plastic bottles and other plastic products are discarded as solid waste after use, due to random littering, difficult to degrade and treat, causing hail pollution to the ecological environment and landscape.
First of all, it will pollute the environment, and environmental pollution is pollution to our human beings, which will cause some diseases. Secondly, the pollution of life will be harmful to our survival and the lives of those who have risen to the top.

Packaging bags, agricultural mulch films, disposable tableware, plastic bottles and other plastic products are discarded as solid waste after the use of state talks, due to random littering, it is difficult to degrade and treat, and the pollution caused to the ecological environment and landscape。Introduction to white pollution and hazards in the book: The state implements the "plastic restriction order" to limit and reduce the use of plastic bags and curb "white pollution".

Pollution Status:
According to the survey,3% of Beijing's domestic waste is waste plastic packaging, with a total of about 140,000 tons per year7% of Shanghai's domestic waste is waste plastic packaging, with a total annual volume of about 190,000 tonsTianjin also has more than 100,000 tons of waste plastic packaging every year. Every year, Beijing discards about 2.3 billion plastic bags, about 100 million disposable plastic tableware, and about 6.75 million square meters of waste agricultural film in the environment. >>>More
