On November 17, the Nantong Data Bureau issued a decision regarding the re-approval of the environmental impact assessment report for the high-end polyolefin new materials project of Lanhai New Materials (Tongzhou Bay) Co., Ltd. The approval decision issued (Tongshu Data Approval [2025] No. 342) (see attachment) is hereby announced. The project is located in the Green Chemicals Development Zone (main port) of the Tongzhou Bay River-Sea Integrated Development Demonstration Area in Jiangsu Province. The original project received the environmental impact assessment approval from the Nantong Data Bureau on August 30, 2024 (Document No. Tong Data Approval [2024] 40). Following the approval of the environmental impact assessment, the production process for the styrene-butadiene rubber facility was changed from Italian IPT technology to CNPC’s own technology. The land reserved for the innovation center was moved from the northeast corner of the plant site to the southern side. The number of recirculation water systems increased from one to two (with the designed recirculation water supply capacity remaining at 40,000 cubic meters per hour). The capacity of the propylene storage tanks was increased from 1,000 cubic meters to 3,000 cubic meters. In the wastewater treatment area, the incineration equipment used was changed from RTO units to TO units; the recycled waste gas from various facilities within the plant is now sent to TO units for incineration. This change constitutes a major alteration, requiring the environmental impact assessment documents to be resubmitted in accordance with the law. After the changes, the project scope includes: the construction of 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.
