It was learned on January 16 that the environmental impact assessment report for Jiangsu Hongjing New Materials Co., Ltd.’s 100,000-ton/year high-end polyolefin monomer production facility and related facilities (Phase 2) has entered the approval process. On December 25, 2024, the official website of Shenghong Petrochemical issued a announcement announcing the second public disclosure regarding the environmental impact assessment for the 100,000-ton/year high-end polyolefin monomer production facility and related infrastructure project (Phase 2) of Jiangsu Hongjing New Materials Co., Ltd. Project Name: 100,000 tons/year High-End Polyolefin Monomer Plant and Supporting Facilities Project (Phase II) ; Nature of construction: New construction. Location of construction: Within the existing factory premises of Jiangsu Hongjing New Materials Co., Ltd. Total investment amount: The total investment amounts to 2,484,720,000 yuan ; The total investment for Phase 1 of the project is 2,015,984,200 yuan, while the total investment for Phase 2 is 4,687,358,000 yuan. The investment in environmental protection measures for Phase 2 amounts to 49,595,000 yuan, accounting for 10.67% of the total investment for Phase 1. Construction scale and content: This project will construct a 50,000-ton/year ethylene oligomerization unit. The project is constructed in phases, and the current construction phase is Phase 2 of the project; the evaluation also covers Phase 2. The proposed 100,000-ton/year high-end polyolefin monomer plant and associated facilities project (Phase II) will use the three-ring tube ethylene oligomerization method to produce 1-octene and 1-hexene. The output of 1-octene will be sufficient to meet the needs of the 100,000-ton POE main plant; some of this product will be exported, thereby enabling partial domestic substitution.
