Recently, the Nantong Data Bureau released the acceptance announcement of the environmental impact report for the project by Kersen (Nantong) New Materials Co., Ltd. to produce 1 million tons of bottle-grade polyester chips (800,000 tons of PET and 200,000 tons of RPET) annually, along with 2,178 tons of acetaldehyde as a by-product, which has attracted widespread attention within the industry.

The project is grand in scale, constructed in two phases in an orderly manner.

The project construction site is located on the south side of Latitude Road 2 and the west side of Longitude Road 2 in the Yangkou Port LinGang Industrial Zone, Rudong County, Nantong City, Jiangsu Province, with an area of 138062.66m². The total investment of the project is 234023 million yuan, of which about 11250 million yuan is invested in environmental protection, accounting for 4.8% of the total investment.

The proposed project aims to have a total annual production capacity of 1,000,000 tons of bottle-grade polyester chips (800,000 tons of PET and 200,000 tons of RPET) and 2,178 tons of acetaldehyde as a by-product, constructed in two phases. The first phase has a total investment of 102,676 million yuan, which will include the construction of 2 PET production lines with an annual capacity of 200,000 tons each (including esterification units and polymerization units), 1 set of acetaldehyde recovery unit (with an annual capacity of 908.3 tons for the first phase), and corresponding utility and auxiliary facilities. The second phase, with a total investment of 131,347 million yuan, will add another 2 PET production lines with an annual capacity of 200,000 tons each, along with 1 new RPET production line with an annual capacity of 200,000 tons (including bottle flake recycling units and polymerization units), and supporting utility and auxiliary facilities. After the completion of the second phase, the total annual production of acetaldehyde across the entire plant will reach 2,178 tons.

Advanced technology empowerment, leading industry development

On the technical level, this project is full of highlights. The PET production facility adopts proprietary technology from Oerlikon Barmag Huitong (Yangzhou) Engineering Co., Ltd. (referred to as: OBHE), providing a solid guarantee for product quality. The de-aldehyding equipment accompanying the PET production uses patented technology from the construction unit, KOKSAN Group, replacing conventional nitrogen with compressed air for de-aldehyding of high-viscosity chips during the polymerization stage, significantly reducing operating costs and energy consumption, with evident technological advancement.

And the RPET synthesis process also adopts the patented technology of KOKSAN Group, chemically glycolyzing the purchased fragmented bottle chips, and then repolymerizing to produce high viscosity chips (IV=0.820), which are ultimately fed into the unique de-aldehyding device of KOKSAN Group for de-aldehyding treatment, achieving the regeneration of fragmented bottle chips, which is a first in the country. This innovative technology not only helps in the recycling of resources but also aligns with the current green and environmentally friendly development concept.

Kersen Group is well-funded, creating a "super matrix"

Kesen (Nantong) New Materials Co., Ltd. was established on September 2, 2024, as a subsidiary of the Turkish Kesen Group invested in China. As a leading enterprise in the green packaging industry chain in Central and Western Asia, the Turkish Kesen Group mainly serves more than 100 countries in North Africa, the Middle East, Western Asia, and Europe, supplying food-grade polyester packaging products. Its cooperative clients include globally renowned beverage and oil producers such as Coca-Cola, Pepsi, and Nestle.

In November 2024, the Kersen Group invested $710 million, planning to build a 2.2 million ton "green polyester new material" project in five phases. Among them, the first phase's two production lines with an annual capacity of 200,000 tons of bottle-grade polyester chips have attracted much attention. This is also the first production line in the country to use the liquid-phase viscosity-increasing one-step process route for producing bottle-grade polyester chips. After production starts, about 1,000 tons of PTA raw materials will be needed every day.

According to the project schedule, the first phase is expected to complete the foundation excavation in April, start the main construction at the end of the month, top out the polyester building in August, and deliver for installation by the end of September. The entire project is scheduled to be completed and put into operation by June next year. After reaching full production, the project can achieve an annual output value of 2.8 billion yuan. The completion of this project will not only further improve the industrial chain layout of Kersen Group but also inject new vitality into the economic development of Nantong area.
