First, it is necessary to correctly understand the degradation of plastic 1. Degradable plastic is a promising environmental protection product
In the past 100 years, the plastics industry has grown from small to large and has reached an annual output of more than 150 million tons. It has become an indispensable application in all fields of industry, agriculture, national defense, scientific research, and people’s daily life. s material. Due to the large number of applications of plastics, waste plastic products are also increasing day by day. Most plastics are stable in performance, and they are not easily degraded by various environmental factors in the natural world. In addition, people are not aware of the harmful effects of waste plastics on the environment and are not disposed of effectively. As for the serious harm caused to the environment by waste plastics, so-called white pollution has emerged. In recent years, accumulating successful experience at home and abroad, people have taken active measures to control waste plastics, such as the reduction of plastic packaging materials, repeated use, recycling, and so on. However, the use of degradable plastics is more advantageous for those products that are not easy to recycle or have little recycling value and are economically difficult to recycle. Such as shopping bags and disposable tableware. Others, such as agricultural mulch, nursery cups, women's sanitary napkins, medical plastic products, etc., are also huge potential markets for degradable plastics. The industrialized degradable plastic products are still a very small part of the potential market for degradable plastics. It can be expected that the prospect of degrading plastics is very bright.

2. Degradable plastics are a specific type of plastic. Plastics have become a large class of new materials and are widely used. The reason why it is so widely used is that, besides convenient molding and low cost, its variety, performance, and ability to adapt to a wide variety of specific needs is a very important factor. For example, in general-purpose plastics, polyethylene has poor heat resistance, but it is chemically stable, resistant to acids, alkalis, salts, and various chemical substances, and it has excellent low-temperature resistance and can be used normally at -50 °C. Polypropylene's resistance Low temperature performance, but good strength and rigidity, and good heat resistance, can be used at high temperatures of 120 °C and so on. Stabilized plastics have excellent resistance to aging and can be used for long periods of time. For example, the estimated value of the service life of plastic water pipes and sewer pipes is more than 50 years, which is in line with the requirements for high service life of fixed buildings. The best field of application for degradable plastics is the use of products with short cycle times and difficult disposal of waste after use. We should see that the field of application of degradable plastics is not unlimited, it is now, in the future can only be a specific part of the plastic. Exaggeration of the use of degradable plastics is unobjective and extremely harmful, and the positioning of degradable plastics is too high, which is not conducive to the development of degradable plastics.

3. The degradable plastics industry is fraught with difficulties and challenges The degradable plastics industry is an environmental protection industry and is therefore a respected and tempting industry. However, degradable plastic is a fairly young member of the entire plastics family and is still in a stage of growth and improvement. Although the products have been industrialized, they are still immature. In the continuous improvement of performance-cost ratio, improvement of performance (including forming performance, useability, and controllable degradation performance), reduction of costs, and widening of the market, many specific and comparative problems will be encountered. Tough questions. It is necessary to solve the high stability of degradable plastic products during molding, storage and use, and also to rapidly degrade after being discarded. This is a major feature of degradable plastics that is different from conventional ordinary plastics, and is also a research and development of degradable plastics. Difficulties.

Second, do a good job in both the scientific and technological development and market development as a new industry, there is no good business team, there is no strong market development capabilities, to its products to the market, occupy a huge market share is not possible. However, the history of the development of degradable plastics in China in the past two decades tells us that we only attach importance to business management, do not pay attention to scientific and technological work, do not pay attention to technological innovation, or have a strong scientific and technological power and lack market development capabilities. Good development.

Third, the industry must support each other and jointly explore the market of degradable plastics There is a large potential market for degradable plastics. Now the market occupied by degradable plastics is only a tiny fraction of its potential market. Broadening the market for degradable plastics requires a lot of tangible work for each company. Only through the efforts of individual companies is not enough, but also the collective efforts of the group. Under the conditions of a market economy, we will help each other, support each other, and benefit from each other through various mutually beneficial forms of cooperation. In this regard, some companies in Shanghai have taken a welcome step and have conducted fruitful cooperation on the premise of complementary advantages. While satisfying the needs of users and promoting products for the fraternal units, they have also obtained corresponding economic benefits and enhanced the links and solidarity among the companies in the industry. All kinds of cooperation methods that can achieve complementary advantages and achieve “double profit” can all be explored, such as technology participation, asset reorganization, and so on.

Fourth, strict management of the production of degradable plastics, pay attention to product quality first Quality is the life of the enterprise, but also the life of the degradable plastics industry, which must be highly valued. The organic combination of corporate interests and social responsibilities must not produce or sell inferior products that do not meet the national standards, let alone allow fraudulent reputations and falsifications. It is said that some companies add yellow pigments to calcium carbonate masterbatch and pretend to be filled with starch-filled biodegradable masterbatch; some companies do not produce according to the inspection standards after they receive the environmental label, and the actual products do not meet the national standards for degradable plastics. . For such cases, they must be exposed and exposed in a timely manner and reported to relevant departments for serious treatment. For those enterprises that have poor production equipment or technical conditions, or have low product quality or are not stable enough, they should organize their efforts in the premise of double profit. Next, help them continuously improve the quality of their products and produce quality products that meet national standards, making degradable plastics a truly environmentally friendly product.

V. One-industry-based, diversified operations In view of the lack of production tasks for most of the degradable plastics units in China, some are even in a semi-discontinued state and are struggling. At this crucial stage, we must strengthen our belief in science and technology, increase investment in science and technology, and improve our production equipment, processes, and formulas. We must focus on improving product quality and reducing production costs. We must strive to expand the market as soon as possible and overcome difficulties. At the same time, according to market needs, the use of existing equipment and related technologies to produce some non-degradable plastic products. For example, blended degradable plastic production units develop filled, reinforced modified plastics, plastic alloys, and various functional masterbatches. Engaging in the development of these products does not require any additional equipment investment. After these products are put on the market, they can meet social needs and gain economic benefits, which is of great benefit to the current enterprises.
