Since the “white pollution” on the “blacklist” of environmental protection, researchers, plastic companies, environmentalists are studying the “white pollution” solution.
Subsequently, an item of scientific research came one after another. Most are building “biodegradable plastic”, there are many are advertised “can completely solve the white pollution” results.
White pollution, refers to the use of polystyrene, polypropylene, polyvinyl chloride and other polymer compounds made of various types of life plastic products, after use was discarded as solid waste, mostly plastic packaging materials for the white, so called ” White pollution “, usually divided into disposable plastic bags, disposable lunch boxes and disposable plastic film and so on.
In order to solve the white pollution, all relevant enterprises and researchers can spare no effort.
How many technologies come out, are advertised to “thoroughly” solve the “white pollution”!
Recently, it has been reported that there is a disruptive technology that can solve the problem of white pollution “thoroughly”. It is understood that this is a bio-based biodegradable new material polylactic acid production of new technologies, it is a perfect solution to the production of lactic acid from corn, from lactic acid synthesis of polylactic acid, then polylactic acid production can be completely biodegradable products industry chain construction, It can completely solve the problem of “white pollution” that plagues all countries in the world and plays an important role in promoting environmental protection and social development. Meanwhile, it can also promote the rapid development of industries such as agriculture, industry, food, medicine and new materials, or cause a The rise of series of independent industries.
In fact, there are countless new technologies that can solve the problem of white pollution. For the first time in 2017, the related technologies will not be mentioned yet, and there will be countless series of reports in 2017 alone.
For example, “Aspergillus tubingensis” is a major breakthrough made by scientists from the Chinese Academy of Sciences in the field of plastic biodegradation. For the first time, the researchers found a new strain of Aspergillus tubinosum, a new strain of polyurethane plastics that can be efficiently degraded, and said the fungus is expected to be the “weapon” for treating white pollution in the future. The research indicates that under the action of “Aspergillus tubinosus”, the biodegradation process of plastic, which was originally difficult to degrade in the natural environment, can be clearly seen in two weeks. After two months, the plastic polymer on the medium basically disappeared. 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, Jilin Province “300000 tons / year of carbon dioxide-based biodegradable plastics” and “300000 tons / year of nano-high activity of silica” project held a groundbreaking ceremony, the project allegedly used in Changchun should be poly propylene carbonate Ester (PPC) biodegradable plastics third-generation synthesis technology, the project’s industrialization not only to solve the “white pollution” of the world to find a practical solution, but also for the effective use of carbon dioxide to find the best ways and means.
Beijing University of Aeronautics and Astronautics Professor Yang Jun is a decade sword, revealing the mystery of insects eat plastic, opened up an effective way of plastic degradation.
There is also through the study of leaves, carbon dioxide, corn starch, developed a solution to white pollution.
In foreign countries, such as the United States, some scientists also found that the pyridylammonium hafnium compounds as olefin polymerization initiator can be synthesized high molecular weight PE-b-iPP diblock copolymer and multiblock copolymer, and precisely control the length of the block The discovery is also said to help solve the global white pollution problem.
…
In short, the technology that can solve the white pollution really is not a minority, but up to now, white pollution is still plaguing the public, and its harm has not been alleviated, then Xiaobian can not help but wonder whether these technologies have any effect, or that these technologies From the advent of the “thorough resolution of white pollution,” this road, how long? Xiaobian is not profane science, just do not want every advent of scientific research to bring hope to everyone, let everyone see the dawn of the silent, so do not say your results “is expected to solve the white pollution” or “will be resolved White pollution “, we do not want to hear the report of these empty-headed brain, please take the result to speak, this is the best gift for the cause of environmental protection.
