Thread Content
On October 23, a public notice was issued regarding the proposed approval of the Environmental Impact Assessment report for Blue Sea New Materials (Tongzhou Bay) Co., Ltd.’s high-end polyolefin new materials project (re-submitted for approval). Construction location: Green Chemicals Expansion Zone, Tongzhou Bay River-Sea Integrated Development Demonstration Area ； Construction unit: Blue Sea New Materials (Tongzhou Bay) Co., Ltd ； EIA preparation unit: Jiangsu Provincial Environmental Engineering Technology Co., Ltd ； Project overview: Based on the conclusions of the project’s environmental impact assessment, and assuming that the enterprise strictly implements all the ecological and environmental protection measures as well as environmental risk prevention measures outlined in the report, and that various pollutants are discharged at levels within acceptable limits without exceeding the set total amounts, then from an environmental protection perspective alone, it is feasible to construct the project at the proposed location. The project is located in the Green Chemicals Expansion Area (Main Port) of the Tongzhou Bay River-Sea Integrated Development Demonstration Zone in Jiangsu Province. The project utilizes the ethylene resources from coastal refining and chemical projects within the China National Petroleum Corporation’s system, and relies primarily on China National Petroleum’s own technologies to produce new material products such as POE, FDPE (solution-process octene copolymer), EPDM, and 1-hexene/1-octene. The project plans to build 1 set of POE production facility with an annual capacity of 100,000 tons, 1 set of 1-hexene/1-octene production facility with an annual capacity of 100,000 tons, 1 set of FDPE production facility (solution-based octene copolymerization) with an annual capacity of 200,000 tons, 2 sets of EPDM production facilities with an annual capacity of 25,000 tons each, 2 sets of hydrogen production facilities using electrolysis of water with a capacity of 1,000 standard cubic meters per hour, along with the necessary utility systems and auxiliary facilities. The total investment for the project is 1,011,146 million yuan, of which 942,000 million yuan is allocated to environmental protection measures ； The total workforce of the plant is 539 people, of whom 509 are operators and 30 are managers ； 4 shifts with a 3-shift operation system, resulting in an annual operating time of 8,000 hours for the equipment. Project construction timeline: On September 26, 2024, the main construction work of the project began in Nantong, Jiangsu, marking the start of the comprehensive construction phase. In January 2025, the environmental impact assessment for the accompanying dock project was made public, while work on the underground structures was carried out to pave the way for the construction of the above-ground structures. In February 2025, the project’s environmental impact assessment was submitted for re-approval and made public, with environmental procedures improved to meet the requirements of technological upgrades. On March 15, 2025, the commissioning ceremony for the core unit was held, marking the entry of the project into its peak phase of construction at the unit level. In April 2025, the construction of the heat exchange station facility and the No. 2 circulating water plant commenced one after another, accelerating the development of the utility systems. On October 10, Blue Sea New Materials announced the results of its \"100-Day Summer Campaign\": the target progress for the high-end polyolefin project was 40.5%, while the actual progress achieved was 45.6%, exceeding the target by 5.1 percentage points.

Latest project progress: According to available information, the high-end polyolefin new materials project of Blue Ocean New Materials (Tongzhou Bay) Co., Ltd. entered the critical stage of public announcement prior to approval for environmental impact assessment on October 23, 2025. This indicates that the project has taken a solid step forward on the path to being built in a legal and compliant manner. What is even more noteworthy is its construction speed. As of October 10, 2025, following the \"Summer 100-Day Campaign,\" the actual completion rate for this project reached 45.6%, which is 5.1 percentage points ahead of the original target. Since the main construction work commenced officially on September 26, 2024, in just over a year the project has moved from completing the underground works to the peak phase of equipment installation; such a pace of progress is quite rare for chemical projects worth tens of billions. Strategic significance of the project: Reducing dependence on imported high-end materials. The polyolefin elastomers (POE) and solution-processable octene copolyethylene (FDPE) produced by this project are key basic materials for the aerospace, medical and health, automotive manufacturing, and photovoltaic industries. For a long time, these high-end materials have relied heavily on imports; the completion of this project will significantly enhance China’s ability to ensure self-sufficiency in these areas. Promoting the high-end transformation of the industry: This project is a strategic step taken by China National Petroleum Corporation to shift from a focus on oil refining to a modern energy, chemical, and materials industry that combines both basic and high-end products. It makes full use of the ethylene resources and proprietary technologies within China’s petroleum industry, enabling a transition from the production of traditional fuels to high-value chemical materials. Building an innovative industrial ecosystem: The ambition of this project goes beyond mere production. By synchronizing the planning of the pilot plant and aiming to raise the proportion of researchers and technical service personnel to around 50%, the goal is to turn Tongzhou Bay into an innovation technology incubation hub for China National Petroleum Corporation, thereby promoting the deep integration of technological innovation and industrial innovation. Driving regional green development: Environmental protection investments amounting to nearly 942 million yuan, along with the design of 19 waste gas treatment systems and stringent wastewater treatment measures, reflect the project’s high standards in terms of giving priority to ecology and promoting green development, setting a new benchmark for the industry. Technical autonomy and industrial collaboration: The core competitiveness of this project lies in its solid technical foundation and clear strategic approach. Technological autonomy: A notable feature of the project is that it relies primarily on China National Petroleum Corporation’s own proprietary technologies. This means that while breaking foreign technological monopolies, the project also pushes China’s independently developed chemical technologies to the forefront of large-scale industrial application. Clear implementation path: The project adopts a pragmatic strategy of \"overall deployment and phased implementation\". In the short term, the market has been entered quickly by purchasing ethylene; in the long term, plans are in place to build ethylene production facilities to ensure a stable supply of raw materials and maintain competitiveness across the entire value chain. Reserving space for development: Proactively, the project includes a 7.74-square-kilometer area designated as a future expansion zone in its planning. This reserves valuable strategic space for taking on more projects related to new chemical materials in the future and for establishing an industrial cluster led by CNPC. The rapid progress of the Blue Sea New Materials project in Tongzhou Bay indicates that a new chapter is being written in China’s field of high-end chemical materials. It is not merely a large-scale industrial facility that requires substantial investment; it is also a technological hub that drives industrial transformation and an innovation engine that fosters regional development. When this project is fully completed and put into operation in the future, it will not only generate hundreds of thousands of tons of high-quality new materials each year, but also provide China’s petrochemical industry with the confidence and strength to stand out in the global industrial chain competition.
