One of the most important things to do after using this substance is to recycle it. Recycling of polyethylene terephthalate in different industries is done by different factories. The most important thing about PET recycling is that you need to find the major recyclers of this material to get the best results from recycling.

The main recyclers of this material are in France and Japan. These two countries perform PET recycling with up-to-date and high-efficiency methods to get the best results. This also reduces environmental pollution in these countries.

Why should we use the enzymatic method to recycle polyethylene terephthalate?

There are several methods for recycling polyethylene terephthalate, which can also be disposed of using incineration and burial methods. But the method of incineration produces toxic gases and fumes that are harmful to human and animal health. In addition, burying pet waste will deplete the world’s landfill capacity.

Therefore, using enzymatic methods to recycle polyethylene terephthalate is the best method. In different industries, the use of enzymatic methods for recycling polyethylene terephthalate is done with certain principles. It is a polymer and must be converted to its monomeric components.

To convert a polymer to a monomer in polyethylene terephthalate, we must remove the ester bonds. To do this, we must use the right enzymes under the right conditions to break down the ester bonds and break down the polymer into a monomer.

For this purpose, different conditions about the ambient temperature and the properties of the enzymes should be investigated so that after the use of enzymes, polyethylene terephthalate materials are well recycled. After recycling, the steps of molding polyethylene terephthalate are very simple; Because this material has very good properties such as good moldability.

We know that increasing heat increases the movement of molecules in a substance. This causes the ester molecules in the polyethylene terephthalate compound to separate. As a result, the recycling process is better. However, increasing the temperature will destroy the stability of enzymes in the process of hydrolysis of polyethylene terephthalate.

So we have to consider special conditions to get the best result from the recycling of polyethylene terephthalate. The most important thing in using enzymes to recycle polyethylene terephthalate is to create the right conditions for them. Temperatures of 70 to 80 ° C give the best results for the recycling of polyethylene terephthalate.

Now if we lower this temperature, the recycling of polyethylene terephthalate will be a little difficult. At this high temperature, care must be taken that the hydrolyzing enzymes of polyethylene terephthalate do not lose their properties. So we have to look at methods to increase the thermal stability of PET hydrolase. Here are the most important methods to increase the thermal stability of PET hydrolase:

1. The immobility of enzymes is very important!

We know that immobility increases the stability of enzymes! Suppose we have an enzyme that has little mobility, this enzyme can easily maintain its stability and participate in various reactions. One of the most important ways to increase the stability of enzymes is to immobilize them.

Although this is one of the methods to increase the thermal stability of PET hydrolase increases the stability, but sometimes the result will be the opposite! It may happen that the types of enzymes that we have immobilized enter into a reaction. Then here a certain hardness is observed in the solution.

This prevents any of the enzymes from reaching the level of hydrolysis of polyethylene terephthalate! This prevents the recycling of polyethylene terephthalate. However, the immobilization of enzymes is one of the most important methods to increase the thermal stability of PET hydrolase.

2. Enzyme Glycosylation is one of the methods to increase the thermal stability of PET hydrolase

Glycosylation is the combination of a polysaccharide called glycan with a protein. Our protein is an enzyme. For example, protease enzyme, which is a protein enzyme, can be combined with glycan. This leads to successful Glycosylation.

It has been tested in various experiments that even at temperatures above 70 degrees Celsius, this enzyme can play its role well. In addition to the good effect of this enzyme, this increases the reaction efficiency. In addition, the enzyme will no longer be harmed.

For this reason, this method can be used to increase the recycling reliability of polyethylene terephthalate. This is one of the most important methods to increase the thermal stability of PET hydrolase can be done in different conditions, it is important how you do glycosylation!

3. Screening to produce heat-resistant enzymes

The use of natural thermophiles and the screening of hydrophobic and thermophilic materials from the structure of enzymes increases their stability against heat. In general, thermophilic chromosomes can increase the thermal resistance of polyethylene terephthalates. This means that when the temperature increases to increase the efficiency of the polyethylene terephthalate recycling reaction, we no longer face the problem of losing the properties of enzymes.

This is one of the most important methods to increase the thermal stability of PET hydrolase. By using this solution, the safety of enzymes against heat increase can be guaranteed! This allows the enzymes to easily enter the reactions and play their role.
