    [ Focus on Chemical Machinery and Equipment Network ] The strength of a country is closely related to economic development, but at the same time, national development cannot ignore the protection of the ecological environment.
    The relationship between the ecological environment and economic development is like the relationship between nature and humans .
    As my country continues to attach importance to environmental protection, relevant policies have been continuously introduced.
    Among them, in response to the plastic pollution problem that has been increasing in recent years, my country has stepped forward the implementation of the "plastic ban".
    Now it is difficult to see plastic straws in and out of major restaurants and shopping malls, and even takeaways.
    The packaging bags have also begun to use paper bags or non-woven bags instead.
    However, in response to the still serious "plastic" crisis, is this step enough?

    Plastic is a chemically stable polymer compound.
    It has strong plasticity, corrosion resistance and stability.
    This has become its advantage and its disadvantage.
    From a practical point of view, the characteristics of plastic make it possible to produce a variety of products, and plastic products have good durability; from the perspective of disposal, if the recycling process is improper, once the waste plastic flows into the natural environment It is difficult to degrade naturally in the environment, and will threaten the health of wild animals and destroy the environment and ecology due to biological activities.

    Although today's relevant policies can curb the rate at which we produce plastic, the key to the treatment of white pollution is still plastic degradation.
    To solve the problem of plastic degradation, there are two main entry points.
    One is to accelerate the development of degradable plastic materials.
    In fact, in recent years, there are actually quite a few new material achievements, but they generally have two problems: production cost and difficulty of promotion.  

      At present, most of the new materials that are considered to be expected to replace traditional plastics, most of the production processes are relatively complicated, and the raw materials are not cheap, which also leads to a large amount of production cost input in the process of using these materials, and Indirectly caused the price to rise.
    On the other hand, this kind of material actually has certain limitations in the application field, so it is also very difficult for residents to use and accept this kind of material correctly.
    Of course, objectively speaking, these problems should be gradually solved with the development of technology.  

      In addition to researching and developing new materials, it is also an effective idea to study ways to accelerate the degradation of plastics, and this idea is more conducive to the treatment of existing environmental problems.
    In recent years, many related achievements have been publicized.
    On April 25 this year, the international academic journal "Hazardous Materials" reported a research result of Sun Chaomin's team at the Institute of Oceanology, Chinese Academy of Sciences.
    The report mentioned that the team found that polyethylene terephthalic acid can be effectively degraded.
    The marine microbial flora and enzymes of two plastics, ester (PET) and polyethylene (PE), provide an important theoretical basis for obtaining plastic degrading microorganisms and functional enzymes, and developing biological products that degrade plastic waste, and are expected to solve the problem of polyethylene degradation .  

      It is understood that the research has been carried out since 2016.
    In the process, scientific instruments including infrared spectroscopy, gel permeation chromatography, X-ray diffraction, high performance liquid chromatography and mass spectrometry were used to observe and analyze the process of colony degradation of plastic.
    Screen out enzymes that can obviously degrade PE plastic.  

      Editor's comment: People are eager to solve the problem of white pollution because we are aware of the threat of white pollution to us, and it also involves the topic of responsibility.
    Nowadays, technology continues to develop.
    Perhaps, from the perspective of the development of the times, it is only a matter of time to solve white pollution.
    But from my personal point of view, compared with the development of technology, if we want to fundamentally end environmental problems, strengthening the awareness of residents may be the real key.
