Qiantang River surges forward, and a new green polyester industrial cluster stands erect on the old mudflat of Keqiao Binhai. In December, on the important milestone of the fifth anniversary of the implementation of the national "dual carbon" target, the first phase of the 50000 ton Jianxin Jiaren New Materials Green Recycling Polyester Project, which was constructed by Jinggong Technology under the EPC general contracting mode, was successfully put into operation!

On the morning of December 6th, the first phase of the 50000 ton green recycled polyester project of Jianxin Jiaren New Materials was successfully put into operation and the commendation ceremony was held grandly. Sun Guojun, Chairman of Jinggong Technology, Guo Yongzhong, Chairman of Jianxin Jiaren, and all members of the project teams from both sides witnessed this milestone moment together. The smooth operation of this project marks a historic breakthrough in the development of China's green, low-carbon, and circular industries by achieving a "zero to one" production line for recycled polyester with a capacity of 10000 tons using chemical methods.

At the ceremony, Chairman Sun Guojun delivered an important speech. He said that after a difficult thousand day battle, we have jointly ushered in the successful operation of the first 50000 tons. The achievement of this answer sheet depends on the hard work and wisdom of the Jiaren team and the technology team for this green cause. Operation signifies a new starting point and a crucial step for Seiko to move from being a "participant" to a "definer". In the future, we will continue to optimize our processes, address industry pain points, lead industry standards, and strive to become the world's top.

Careful layout and efficient promotion

Since taking over the project in December 2023, Jinggong Technology has faced many challenges such as heavy design tasks, tight schedules, multiple cross operations, and wide construction areas. It has established a special division for resource recycling as soon as possible, adhering to the core principles of "technology leadership and efficient implementation", focusing on the three core links of core process optimization, key equipment verification design, and procurement resource cost control, and precisely layout to promote project construction.

In the design phase, the project team repeatedly discusses and carefully optimizes every detail from material balance to process flow, from equipment and instrument selection to pipeline layout; At the same time, an intelligent control system covering the entire process was designed and constructed, achieving intelligent production that integrates the entire chain from feeding, reaction, finished products to packaging.

In the process of promotion, the team always adheres to high standards and strict requirements, strictly controls quality and safety with the "four precision" standards, actively leads the organization of construction technology disclosure, consolidates responsibilities layer by layer, and ensures that every technical point, every process, and every standard is accurately implemented.

Overcoming difficulties and striving for excellence

On the road to victory, there is no 'tomorrow' to wait for; The current construction period is limited to 'today'.

Winter sharpens bones and rises against the cold.At the beginning of the project launch, it was in the midst of extreme cold along the coast, with temperatures of over minus ten degrees Celsius. The frozen soil layer was as hard as iron, and the surface of equipment pipelines froze and frozen. The project team scientifically implements the "staggered operation and coordinated installation" mode, coordinating the pace of equipment entry and foundation construction. Even during the Spring Festival, the team remained steadfast on the front line, laying a solid foundation for the smooth start of the project with their hands red from the cold.

In the scorching summer, we fight fiercely with our backs against the water.In the blink of an eye, the scorching sun has baked the earth, and the project has also reached the most difficult stage. The installation and commissioning of pipelines and the "three checks and four determinations" of equipment need to be carried out simultaneously. In the face of critical moments, all members of the project team gathered together, anchored their goals, and carried out map battles - pipeline installation raced against time, equipment debugging pursued excellence, and completed a carpet like inspection of 95 kilometers of pipelines, more than 1300 devices, more than 3600 instruments, more than 13000 valves, and more than 9000 automated control points. With unwavering determination, they accurately held onto every impossible progress node.

In the end, the project team achieved the "engineering miracle" of completing the installation of mainline equipment in 3 months and meeting the conditions for trial production in 8 months with astonishing perseverance and professional execution, and successfully realized the full chain operation from equipment manufacturing, process connection to stable operation. This tough journey demonstrates the technical expertise and management resilience of Jinggong people in the field of intelligent manufacturing of high-end equipment, setting a high standard, fast-paced, and strong execution project model for the industry.

Technology leads to endless vitality

The smooth operation of the first phase 50000 ton recycled polyester continuous production line provides a replicable engineering example for the industrialization of domestic 10000 ton recycled polyester recycling, and once again establishes Jinggong Technology as the only industry leader in China with the ability to deliver the entire line of recycled polyester continuous production line.

After the project is put into operation, for every 100000 tons of waste polyester recycled, it is depolymerized through the "chemical polyester recycling" process and reduced into DMT products with a purity of 99.99%. Some DMT is then converted into recycled PET chips through ester exchange and condensation, which can reduce carbon emissions by about 220000 tons, effectively reducing dependence on petroleum resources and truly achieving a perfect closed loop from waste textiles to recycled new materials. This is of great significance for promoting the national "dual carbon" goal.

Walk towards the "new" and cultivate deeply towards the "green"; Limited resources, infinite cycles. Looking ahead to the future, Jinggong Technology will continue to deeply cultivate the green and circular industry, constantly update and iterate the complete set of equipment and process technology for recycled polyester, and contribute more Jinggong strength to building China's billion dollar green recycling industry cluster.
