Latest company news about Why is Recyclability the Best Way for Plastics to Understand the World?

Plastic itself causes very low pollution to the environment. It is people who pollute the environment. People's living habits cause pollution to the environment. It is people's irresponsibility that causes environmental pollution. It is people's opportunism that cause environmental pollution.

 

People are the main body, and plastic is just a back-up. In life, we cannot do without all kinds of plastic bottles. Many plastic bottles will be sent to the recycling bin after a short stay in our hands. Do you know where the empty plastic bottles ended up?

There is no era that pays more attention to recyclability than today
You may not know that whether the problem of plastic pollution can be effectively solved depends largely on whether the design of plastic products is easy to recycle and regenerate. In the domestic plastics industry chain, there is no design standard for recyclability so far. The upstream chaos and irregularities of the industry chain are transmitted to the downstream of the industry chain, causing a lot of problems in the recycling industry.

 

According to international standards, the American Plastics Recycling Association (APR) and the European Plastics Recycling Association (PRE) have respectively developed plastic recycling design guidelines for their respective recycling systems in 2009 and 2017, but China is still in a blank.

 

We hope that brands, manufacturers, and packaging companies in the upper reaches of the plastics industry chain can participate in the project of plastic recyclability design, and jointly promote the introduction of China’s "Global Specification for Plastic Recyclable Design", and let us The plastic industry chain has gradually become one, which is more conducive to the healthy development of domestic enterprises.

 

The truth about plastic recycling
What plastics can be recycled, how many times can be recycled, how many can be recycled twice, and which ones are actually recycled. All the truth about plastic recycling starts with those globally consistent plastic recycling labels.

 

These signs, such as the circular arrow on the bottom of the mineral water bottle and the number inside, are often misunderstood as recycling, but this is not the case. These numbers indicate the type of resin, not the degree of recovery.

Many plastic packaging is a mixture of several plastics, making the difficulty even higher. For example, the viscosity range of PET bottle label paper, bottle cap and bottle body is not uniform and irregular. Most beverage bottle trademarks are made of PVC. In the sorting process, because the density of PVC and PET are the same, this greatly increases the difficulty of sorting and handling.


The plastic sorting system is very complicated, and most plastics are actually incinerated or landfilled. Because the density of different types of plastics is very small, there are many types of plastics that have similar densities, and there are more than 50 types of plastics, which makes sorting and reprocessing plastics the most difficult thing of all materials. .

From the most primitive environmental point of view, all materials are worthy of being recycled, but considering economic factors, the situation becomes complicated. Changes in plastic prices and oil prices are synchronized. When the market is sluggish, after plastic raw materials become very low, recycling plastic becomes unattractive.

 

In addition, many plastic products are degraded every time they are reprocessed, which leads to lower and lower value of recycled plastics.

 

Plastic bags, styrofoam packaging and coffee cups can theoretically be recycled, and the manpower and resources spent on sorting are not proportional to recycling.

The plastic problem has gradually become a global phenomenon, and Frans Timmermans of the European Commission recently declared war on single-use plastics. He said: "Disposable plastic products only need 5 seconds to be produced, 5 minutes of use, but it takes 500 years to degrade."
It is very frustrating to think that the archeological remains of our time are plastic bags, yogurt bottles and disposable cups.

 

How does my country handle so many plastic bottles every year?

 

Environmental problems are not only a problem facing China, but also a common problem faced by the whole world. Therefore, in recent years, all parts of the country have continuously introduced related governance measures to address environmental problems.
We can often see that some scavengers will search for plastic bottles near the trash cans, and then sell them to vendors after they have collected a certain amount, and the recycled vendors then pull these plastic bottles to recycling plants. According to statistics, in my country, as many as 3.6 million plastic bottles are produced every year.

Some people might think that these recycled plastics are directly disposed of like other garbage, such as being buried in the ground or burning. But these two treatment methods are very harmful to the environment, and plastic bottles are non-degradable materials. If buried underground, it will destroy the structure of the land and cause water pollution. Water quality is closely related to each of us. Naturally, we will not take the method of burying, and burning is even more impossible. The burning of plastics will Many toxic chemicals are produced, which seriously pollute the air.

In fact, for these plastic bottles, the state has a more clever way to deal with it, which is to re-use these discarded plastic bottles.

The materials used to make plastic bottles are still useful for human beings, for example, they can be used as materials for our usual clothes. Simply put, after the discarded plastic bottles are processed, they can be remade into our personal clothing.

 

The polyester used in the plastic bottle is the same raw material as the polyester fabric and polyester fabric mentioned in the textile industry. Approximately 80% of the recycled plastic bottles will be used in the textile industry, which is called recycled fiber inside the industry.

 

Turning plastic bottles into recycled fibers is not a simple process. In terms of preparation, there are currently two main processing methods for this green fiber. One is to prepare recycled polyester by crystallization and drying of recycled materials such as screw melt extrusion, two-stage high-precision filtration technology and other technologies.

The other is to completely reduce the recycled waste clothes to monomer molecular level through chemical alcoholysis, filter to remove impurities, and then polymerize into PET chips, and finally spin into fibers. As the world's largest chemical fiber producer, China has already mastered the key technologies and has continued to carry out technological innovation.

 

The trouble should end it. Our generation should take the responsibility of reducing waste and find solutions from the source of recyclability design. The healthy development of the plastics industry is a marathon. No marathon in the world is completed without clear standards.

 

Regardless of the era of commercial civilization, the way to continue to make profits is to build a moat to protect the "dividends" of the era as huge "profits." It now appears that there is no era that emphasizes the importance of plastic recyclability design more than today.
