"Mandatory use of recycled materials" will become a global consensus to combat plastic pollution, but the plastic recycling industry has not yet prepared the basic system, especially the serious lack of key standards. In order to accelerate the construction of basic standards for the use of recycled materials, recently, the Plastic Recycling Branch of China Synthetic Resin Association (CPRRA) launched the "Determination of Intermediate Phthalic Acid Content of Post-Consumer Recycling (PCR) Reused Polyester (PET) (Gas Chromatography Method)", "Determination of Intermediate Phthalic Acid Content of Post-Consumer Recycling (PCR) Reused Polyester (PET) (Nuclear Magnetic Resonance Method)", "Traceability Evaluation Requirements for Post-Consumer Recycled Plastics (PCR)", " There are five basic standards: marine plastic recycling traceability evaluation requirements and "green intelligent waste plastic packaging station construction requirements". Topcentral® participated in the compilation of "Determination of Intermediate Phthalic Acid Content of Post-Consumer Recycling (PCR) Reused Polyester (PET) (Gas Chromatography Method)".

With the improvement of environmental protection awareness and the embodiment of the economic benefits of the waste plastic recycling industry, the recycled PET recycling industry has been greatly developed, and recycled PET is widely used in downstream production, on the one hand, it can reduce the pollution of waste to the environment, on the other hand, it can be recycled and save resources. In order to make transparent PET bottles, crystallization must be avoided, and the addition of isophthalic acid can destroy the regularity of the molecular chain, hinder the movement of the molecular chain, and reduce the crystallization ability of macromolecules. Therefore, detecting isophthalic acid in polyester can determine whether the polyester comes from recycled PET bottles. At present, the detection of whether polyester comes from recycled PET bottles is still in the blank stage, and the current few testing methods are cumbersome and complicated, which is not conducive to routine testing and promotion. In view of the problems described, the development and publication of relevant standards is particularly important. As one of the main participating units, Topcentral® promoted the drafting of relevant standards.

Polyethylene Terephthalate™TC-Rester^®rPET is one of Topcentral^® core products, and the company attaches great importance to the research and development and production of rPET products. At present, the waste PET that is recycled, pretreated and further processed by Topcentral^® has become high-performance, high-functional, and high-value-added Polyethylene Terephthalate™TC-Rester^®rPET particles and their high-end functional modified materials. Polyethylene Terephthalate™TC-ResterrPET from Topcentral^® has obtained carbon neutral product certification, from raw material acquisition, product manufacturing, product transportation, product use to recycling, to achieve full life cycle emission reduction, and won the 2022 BRICS Industrial Innovation Competition Winner Award with high-value application research and efficient industrialization project of low-carbon green recycled polyester (PET), which is expected to recycle more than 30,000 tons of waste plastics in the next five years. The output of green high-quality functional materials is 37,500 tons, and the carbon emission reduction compared with primary materials is 106,000 tons.

Being able to participate in the compilation of national standards and group standards benefits from Topcentral^® strong product strength and good service quality, and has been fully affirmed and praised by peer experts, highlighting Topcentral^® soft power and industry influence in the industry. In addition to the preparation of the standard "Determination of Intermediate Phthalic Acid Content in Post-Consumer Recycling (PCR) Reused Polyester (PET) (Gas Chromatography Method)", Topcentral^® has participated in or is participating in the drafting and compilation of a number of standards, and has released 2 national standards and 1 group standard, compiling the latest production processes and processes into standard achievements, leading the development of industry technology and application ahead of time, mastering the leading position and discourse power in the industry, and becoming an important driving force for service upgrading.

As a member of the recycled materials industry, Topcentral^® has the willingness and ability to guide the healthy development of the industry, and at the same time, it will continue to promote the high-quality development of the industry in an all-round way through technological innovation and service upgrading.
