Degradable plastic and recycled plastics are the potential two options to solve the problem of white pollution.

 

1. Degradable plastic is suitable for packaging and agricultural membranes

 

Degradable plastic refers to the performance requirements of its products that can meet the performance requirements of the use. The performance is unchanged during the preservation period. After use, it can degrade into plastics that are harmless to the environment under the natural environment conditions. Degradable plastic has its advantages in terms of performance, practicality, degradability, and safety. In terms of performance, degradable plastic can be achieved or surpassed traditional plastic performance in certain specific fields; in terms of practicality, degradable plastic has the application performance and hygiene performance of similar traditional plastics; in terms of degradability, degradable plastic can be degraded plastic After use, the degradation can be completed quickly (specific microorganisms, temperature, and humidity) in the natural environment, and become fragmented or non -toxic gases that are easily used by the environment to reduce the impact on the environment; in terms of safety, degradable plastic degradation can be degraded The process or residual substance is harmless to the environment and will not affect the survival of humans and other creatures. The biggest obstacle to replacing traditional plastics is also the disadvantage of degradable plastic is that its production cost is higher than similar traditional plastics or recycling plastic. Therefore, in applications areas with short use time such as packaging and agricultural membranes, difficulty recycling, difficult to recycle separation, low performance requirements, and high impurity requirements, degradable plastics have a replacement advantage.

 

2. Recycling plastics are suitable for areas with low hygiene requirements

 

Recycling plastic refers to the plastic raw materials that are re -obtained after processing through physical or chemical methods such as pre -processing, melting granules, and modification. The biggest advantage of recycling plastic is that the price is cheaper than the new material and degradable plastic, and can only process some aspects of the plastic according to different performance needs, and create a corresponding product. In the case of not too many cycles, recycling plastic can maintain similar properties as traditional plastics, or maintain stable performance by mixing with regeneration and new materials. However, after many cycles, the performance of the recycling plastic decreases a lot or to the degree of inaccessible. In addition, it is difficult to maintain good hygiene performance under the premise of ensuring economics. Therefore, recycling plastics are suitable for areas where the number of cycles is not large and the hygiene performance is not high.

 

3. White pollution is mainly derived from the packaging field, and the space can be degraded.

 

Through comparison, degradable plastic has a replacement advantage in the fields of applications that are shorter and difficult to recover in packaging, agricultural membranes, etc. due to its more stable performance and lower recycling costs. The cost of production, the application scenarios that have been used for a long time and easy classification and recycling in lifestyle, building materials, electrical appliances, etc., are more advantageous, and the two complement each other. White pollution is mainly derived from the packaging field. It can degrade plastic more space. As the policy is promoted and cost decreases, the future of the plastic market can be degraded.

 

4. In the field of degradable plastic applications, soft packaging and hard packaging account for 53%

 

In the field of packaging, degradable plastic replacement is being realized. The application of plastic applications is very wide, and the requirements for plastic are different in different fields. The requirements for plastic in the fields of automobiles and appliances are durable, easy to separate, and have a large amount of single plastic. Therefore, the status of traditional plastics is relatively stable. For the packaging fields such as plastic bags, lunch boxes, plastic membranes, express delivery, due to the low amount of plastic monomers, it is easy to pollute and difficult to separate, which makes degradable plastic more opportunities to become a substitute for traditional plastics in these fields.

 

This is also verified from the global degradable plastic demand structure in 2019. The demand for degradable plastics is mainly concentrated in the packaging field, and soft packaging and hard packaging account for 53%. Western Europe and North America have developed earlier, and they have begun to take shape, and the application fields are concentrated in the packaging industry. In 2017, among Western Europe's degradable plastic consumption, shopping bags and production bags accounted for the largest share (29%); in 2017, North American degradable plastic consumption in the total food packaging, lunch boxes and tableware accounted for the largest share (53%(53% To.

 

5. Change to the circular economy

Two weeks before the World Recycling Day this year, the United Nations has passed the legal binding agreement to deal with the serious environmental impact and risks caused by plastic. The purpose is to reduce the many risks brought by plastic. The United Nations asserts that the agreement will manage the full life cycle and requires plastic to be designed to be reused and recyclable, which marks the end of disposable plastic products. In short, this UN agreement aims to transform the life cycle management of plastic from a linear mode to a cycle mode.

To end the world's one -time economic model, standards can play a key role. "The ISO standard has a strong driving force, and it can even promote the development of new market markets in the future." Dr. Achim Ilzhöfer, Chairman of the Chairman.

The number of plastics is huge, there are many types, and the production methods and its market demand are very complicated. Standardization can play an important role in this field, and make specific regulations on plastic characteristics and its supply chain to achieve sustainable use. "The ISO standard can stipulate on the international level. While protecting the intellectual property rights, the value chain partner can better exchange information exchange, so that the material uses from a linear model to a circular economy model." He added. This is also applicable to material recycling technology. ISO standards and technical reports help promote the development of specific materials recycling management at the global level and the formulation of the best available technology. "The role of ISO standardization is to stimulate the market and connect the scattered parts, so that the global economy is more effective and sustainable," said Ilziff. As the global manager of the German Koschuang Chemical Company, Ilzov is well versed in the benefits of standardization. "Since the beginning of the scientific work, I have learned how the standard is to improve the supplier, customers and us.

Between relationships. From the perspective of consumers, standards enable consumers to compare products in a standard and credible way, and to identify which products are more sustainable. "He said certain. As practitioners in the field of plastics and international standard makers, Ilzov actively finds solutions to promote the standardization of plastic sustainable production and consumption." ISO standard can provide solutions for major challenges For example, in the field of micro -plastic, the problem of improper treatment of plastic waste and the environmental impact it brings. "Call for a more circulating plastic economy, including proposing proposals to improve the recyclable, recycling material content, biodegradation ability, and reused use of plastic. Continuous ISO standard. "One of the examples is ISO 15270: 2008" Plastic -Plastic Waste Recycling and Reuse Guide ". This standard builds a framework for formulating future plastic waste recycling standards and specifications in a closed loop. "Ilzov and other experts in the ISO working group hopes to formulate more standards to promote the development and use of sustainable plastics." In order to improve the reuse rate, we must improve the method of plastic collection and classification. The task fell on the waste market. "The standards of re -use design, traceability schemes and waste management are the basis for cyclic use in ecology and economic aspects. In addition, Ilzov is convinced that for different reuse technologies, waste -based raw materials standardized work capacity can work capacity. Quickly improve the reuse rate and provide support for the global market development.
