Polyethylene terephthalate recycling is one of the most important activities to reduce environmental pollution. Because this material has various applications in the plastics industry, recycling it can be one of the best ways to reduce pollution. But wait! Perhaps some modifications can be made to the structure of this polymer. In the continuation of this PETROPROVIDERS article, join us to introduce you to polyethylene terephthalate recycling.

Why is Polyethylene terephthalate recycling important?

One of the most important threats to the environment is plastic pollution around the world. We know that polyethylene terephthalate or PET is one of the most important plastics used worldwide. This material is used to produce all kinds of plastic bottles. Given that PET bottles are produced in millions a day, the entry of all of these into the environment will cause a lot of pollution!

That is why if the PET enters the environment too much, it will be a major concern for the health of the planet. To manage contamination of polyethylene terephthalate, in addition to polyethylene terephthalate recycling, changes can be made in the polymer structure of this material; For example, changes can be made in the mechanical, thermal, chemical, and structural properties of polyethylene terephthalate.

These changes make the decomposition of this substance in the environment faster and faster. It is important to note that these methods are expensive and can be used to recycle or alter the properties of PET, usually causing secondary contamination.

So we see that we have to find simpler and cheaper ways to reduce PET pollution. In this regard, Polyethylene terephthalate recycling using enzymatic methods can be one of the best methods. According to the above, various types of PET hydrolase enzymes can be used in this method.

These enzymes enable the decomposition of PET into monomer units faster; So the molecular weight of this substance will decrease rapidly. It should be noted that in the process of polyethylene terephthalate recycling

  Enzymatically, different conditions must also be examined. These conditions include:

  • Crystal state of matter
  • environment temperature
  • pH environment
  • A variety of enzymatic methods

For example, high ambient temperatures can be used to speed up PET hydrolysis. Of course, this temperature should not be higher than the standard value; Because it may damage enzymes.

Factors affecting the efficiency of polyethylene terephthalate recycling by the enzymatic method

Using enzyme engineering technologies and glycolysis, the thermal stability of enzymes can be increased. Other materials can also be used to increase the efficiency of PET enzymatic hydrolysis reactions. These materials include:

  1. Surfactant
  2. Magnesium ion
  3. Calcium ion
  4. Hydrophobics
  5. Etc…

In the following, we want to do a complete review of polyethylene terephthalate recycling by enzymatic method. Given that there are different ways to do this recycling, we also examined these methods! Of course not in an article; If it sounds good, stay tuned.

Investigate various contaminants of plastics such as PET

We know that there are two very important factors in increasing the pollution of plastic waste around the world; The first factor is the overuse of plastics. The second factor is poor control management to eliminate and eliminate these contaminants.

In recent years, the use of plastics has been increasing day by day. Because various industries use this material in the production of their products, plastic has become an integral part of consumer products. This material has different properties; Some of the most important properties of plastics are:

  • Thermal resistance
  • Hardship
  • Transparency
  • High strength
  • Good moldability
  • lightweight
  • Low production cost

These features made the use of plastic very popular all over the world. So we see that if this material is used well, it will increase the production of higher quality products.

Different applications of plastics increase the use of this material and thus increase various environmental pollutants. Because environmental pollution is seen in different ecosystems, plastics can be found in forests and rivers, and open spaces as well as seas. Plastics are very durable and take almost a thousand years to decompose naturally in the environment; That is why we see that the population of plastics is increasing day by day.

This increase in plastics will pose various dangers to living organisms. Over the past decade, plastic production has grown exponentially. For example, the market for Dioctyl Adipate and the market for polyethylene terephthalate are some of the most important markets we have examined in Petroproviders articles.

Why the need for polyethylene terephthalate recycling using enzymatic methods?

The use of plastic and polymer products has proven to be increasing day by day; In the last twenty years, the production of plastics has increased more than before, and for this reason, the production of plastic waste has almost tripled! As most plastics make their way to the oceans, there have been about 8,300 million plastic wastes in the deep oceans since 1950. By 2050, deep-sea plastic waste is projected to exceed 10 million.

Because plastics are highly resistant to organic solvents, ionizing radiation, and oxidation reactions, they are used in many applications. In general, about 33% of plastics are used for various packaging. Due to the properties and applications of PET, this material has a very high thermal resistance. In addition, the structural stability of PET has made it more popular.

For this reason, this material is used in the packaging industry. This material is transparent, it is a kind of polymer resin, PET can be used in the production of plastic bottles, resins, and films, as well as electrical parts. This is why polyethylene terephthalate recycling is so important.

Polyethylene terephthalate is a semi-aromatic polyester and is produced by polymer reactions. The monomers of this material are joined together by ester bonds. PET is a chemically neutral substance that has a kind of hydrophobic property. This material is resistant to moisture and has a very high melting temperature.

In addition, this material offers excellent hydrolytic stability! For these reasons, the use of PET is very popular in the plastics industry. In addition to this material, a variety of polystyrenes can be used to produce durable plastics.

For example, GPPS polystyrene grade, as well as HIPS, can be used to produce a variety of disposable containers, heat-resistant plastics, transparent and opaque. Given that these materials also need to be recycled, so it is better to consider one of the recycling methods for one of the materials in full. This review should also lead to a conclusion; The result is new and effective methods for polyethylene terephthalate recycling.

Let’s get acquainted with the news of Iran polyethylene terephthalate production and use!

In 2015, high demand for the use of PET plastics, especially in the packaging industry, produced more than 18.8 million tons of plastics worldwide. This is a total of 269 million tons of plastic worldwide. In general, polyethylene terephthalate recycling results in the reuse of 28% PET. These materials are used in the production of bottles and sheets and fibers.

72% of polyethylene terephthalate is released into the environment and this will cause various problems in the lives of animals and humans. Like other plastics, PETs have very little decomposition and it can be said that this material does not decompose naturally in the environment. As a result, many PET plastics are incinerated or disposed of in landfills.

Due to the high cost of polyethylene terephthalate recycling, very little PET is recycled in the industry. Of course, major recyclers of this material can be found to reduce recycling costs.

Increasing environmental pollution has many pollutants for humans. In addition to humans, animals are also threatened by environmental pollution. For example, if plastics remain floating on water, they will be swallowed by animals. It then enters the gastrointestinal tract, closing the airways and even killing certain animals.

In addition, we eat these animals and these contaminants enter the human body. Animals may also eat plastic materials in dry environments; Then we will kill these animals and use their meat and it will make us sick!

Because pets are water-repellent, they can be a source of accumulation of organic pollutants as well as heavy metals. In addition, a variety of toxins can stick to PET plastics and further pollute the environment. These toxins are transported through food chains and threaten the health of the entire planet.
