Subsequently, a series of scientific research results followed. Most of them are creating "biodegradable plastics", and many are advertised as achievements that "can completely solve white pollution".

White pollution refers to all kinds of household plastic products made of polymer compounds such as polystyrene, polypropylene, and polyvinyl chloride, which are discarded as solid waste after use. White pollution" is usually divided into disposable plastic bags, disposable lunch boxes and disposable plastic films, etc.

In order to solve the white pollution, relevant enterprises and scientific researchers have spared no effort.

Recently, there are reports that there is a disruptive technology that can "completely" solve the problem of white pollution. It is understood that this is a new biodegradable new material polylactic acid production technology, which perfectly solves the industrial chain construction of producing lactic acid from corn, synthesizing polylactic acid from lactic acid, and then producing fully biodegradable products from polylactic acid. It can completely solve the "white pollution" problem that plagues countries all over the world, and has an important role in promoting environmental protection and social development. The rise of a series of independent industries.

In fact, there are countless new technologies that can solve white pollution. For the related technologies before 2017, let’s not mention it, there are countless series of reports in 2017 alone.

For example, "Aspergillus tabin", this is a major breakthrough made by scientists of the Chinese Academy of Sciences in the field of plastic biodegradation. The researchers discovered for the first time a new strain of Aspergillus tabin that can efficiently degrade polyurethane plastics, and said that the fungus is expected to become a "sharp weapon" for white pollution control in the future. The study pointed out that under the action of Aspergillus tabin, the biodegradation process of plastics that were originally difficult to degrade in the natural environment could be clearly seen in two weeks, and the plastic polymers on the culture medium basically disappeared after two months. Of course, its degradation efficiency is also affected by a number of environmental factors, including pH, temperature, and the type of medium used.

For another example, the foundation stone laying ceremony was held for the "300,000 tons/year carbon dioxide-based biodegradable plastics" and "300,000 tons/year nanoscale highly active silica" projects in Jilin Province. The third-generation synthesis technology of ester (PPC) biodegradable plastics, the industrialization of the project not only finds a practical solution for solving the "white pollution" world problem, but also finds the best way and method for the effective use of carbon dioxide.

Yang Jun, a professor at the School of Chemistry at Beihang University, has made a breakthrough in ten years, revealing the mystery of how bugs eat plastic and opening up an effective way to degrade plastic.

In addition, through the research of leaves, carbon dioxide, corn starch, etc., a solution to white pollution has been developed.

In foreign countries, such as the United States, some scientists have also found that high molecular weight PE-b-iPP diblock copolymers and multiblock copolymers can be synthesized by using pyridylamino hafnium compounds as olefin polymerization initiators, and the length of the blocks can be precisely controlled. , the discovery is said to also help tackle the global white pollution problem.

……

In short, there are really many technologies that can solve white pollution, but to this day, white pollution still plagues the public, and its harm has not been alleviated, so I can't help but wonder if these technologies are effective, or whether these technologies are effective. How long is the road from its inception to "completely solving white pollution"? The editor is not blaspheming science, but I just don’t want the advent of every scientific research result to bring hope to everyone, so that everyone will be silent after seeing the dawn, so don’t say that your results “probably solve white pollution” or “will solve the problem”. "White pollution", we don't want to listen to these vain reports, please speak with the results, this is the best gift for the cause of environmental protection.
