Tondguyan Petrochemical enters the recycling of PET bottles

In an interview with Shana News Agency, the CEO of Shahid Tondguyan Petrochemical Company claimed that the risk of stopping the production of petrochemical units  because of the manufacture of palladium catalyst has been reduced to zero forever.

The CEO of Shahid Tondguyan Petrochemical Company also mentioned the difference in the exchange rate in the pricing of feed and product, the problem of supplying p-Xylene feed, the impact of oppressive sanctions on the supply of production requirements, the combined import of PET for preform and its combined pricing as the main challenges of the company’s production and trade in Iran.

 Mr. Ghasemi Shahri further explained about the basic repairs of the phase one until the end of the year and investments for the R-pet project . in this projects , according to the CEO, the land has been located and the contractor has been selected. He also called prioritizing the implementation of improvement projects in order to optimize the consumption of energy carriers as one of the future policies and plans of Shahid Tondguyan Petrochemical Company.

R-PET is the granule resulting from the recycling process of PET bottles. PET bottles are gathered from various sources like household recycling collection and from business and manufacturing waste Recycling plants .then it is sorted through the materials – separating the PET plastics from other non-recyclable compounds and removing any contaminants before processing. The purified PET is shredded into grains of plastics that can be left as they are or heated and pressed into pellets for sale to companies looking to use RPET for future packaging.

 Due to the advances in recycling technology, this product provides manufacturers and consumers with preform and bottles with similar performance standards to first-hand bottles and preforms. Converting PET bottles and containers into a valuable resource such as R-PET helps the environment because R-PET has a lower carbon footprint than virgin PET. It also reduces demand for virgin PET, which requires more energy and water to produce.

The latest scientific research found that there was no evidence to suggest that recycled polyester is toxic or causes harm to human health. Under EU rules, from 2021 to 2025, manufacturers of preform and PET bottles are required to use 25% of R-PET in their products.

Shahid Tondguyan Petrochemical Company is the largest producer of important and strategic products of polyethylene terephthalate (PET) and pure terephthalic acid (PTA) in Iran. PET and PTA are used in the textile, preform, pet bottles for medical and pharmaceutical industries. In 2023, The Company produced more than 248,000 tons of bottled grade polyethylene terephthalate (PET-BG) in Iran.

what is a PET preform

A PET Preform is a test tube like piece, with clear and soft surface. It is an intermediate product in Polyethylene Terephthalate (PET) containers production. PET Preforms are shatterproof, Although, quite similar to glass, they are not as fragile . This feature makes them suitable for transportation .

The Preform production is a crucial step in the PET bottle manufacturing process. This intermediate product is low-cost, Eco- friendly, efficient and has production flexibility. The type of Preform used in A PET bottle production is extremely important in determining the durability, appearance and functionality of the final product. The adaptable nature of the PET preform enables the production of high quality, diverse and hygienic designs with glass- like finish. Furthermore, the PET perform does not react with food and beverages, therefore, it is an ideal option for food packaging.

 PET preforms are manufactured through an injection molding process using molds designed based on the general needs of the consumers. Production of the bottles with different shapes and designs is straightforward and accomplished through a stretch blow molding process. It is noticeable that the neck finish of the Preform stays the same during the blow molding process so This part of the Preform is used in the Preform classification.

PET bottles are vastly used in food and cosmetic industries. They are versatile, impact-proof, easy to produce and stock. Their considerable durability, joined with low gas and humidity permeability, makes them an excellent choice in the carbonated drinks packaging.
