On the morning of December 14, Lianyun District held a signing ceremony for the “1+4” billion-yuan industrial projects; 5 major industrial projects with a total investment of 12 billion yuan were officially established in Lianyun, providing strong impetus for the region’s industries to achieve higher levels of development and undergo transformation and upgrading. The 220,000-ton per year spandex fiber production project: The 220,000-ton per year spandex fiber production project in the Green, Low-Carbon, High-End Materials Demonstration Park operated by Lianyungang Industrial Investment Group Co., Ltd. was funded by this company; the total investment amount is 6.46 billion yuan, with a total land area of 590 mu. Once established, this project will help the park develop into a leading hub for two new material industries: carbon fiber and spandex fibers. The project is constructed in three phases; phase one uses Fengyi Oil’s sebacic acid as a raw material to produce 60,000 tons per year of bio-based spandex fiber products ； Phase 2: an annual production capacity of 60,000 tons of recycled spandex fibers ； Phase 3 will have an annual production capacity of 100,000 tons of petrochemical-based spandex fibers. Once the project is fully built and put into operation, it is expected to generate an annual output value of 10 billion yuan and pay 170 million yuan in taxes annually. The project for the annual production of 60,000 tons of hydroquinone and its downstream products is funded and constructed by Jiangsu Sanjili Chemical Co., Ltd., with a total investment of 2 billion yuan. This project aims to promote the high-value utilization of hydroquinone in the industrial park as well as to extend the value chain associated with this substance; it covers an area of 439 mu. The project will be constructed in two phases. Phase 1 has an annual production capacity of 60,000 tons of hydroquinone, 60,000 tons of phenolic phosphorus-based flame retardants, 60,000 tons of rubber additives, and other products ； In the second phase, the production capacity will be 10,000 tons per year of chain-extending agents, 7,000 tons per year of high-intensity vanillin, and 10,000 tons per year of resorcinol and other products. Once the project is fully built and put into operation, it is expected to generate an annual output value of 5.15 billion yuan, with annual tax payments amounting to 720 million yuan. The 100,000-ton/year recycling project for battery-grade new energy materials is funded and constructed by Yantai Kaishi Industrial Co., Ltd., with a total investment of 1.18 billion yuan; it covers an area of 150 mu (aiming to revitalize underperforming enterprises in the industrial park). This project is interconnected with the park’s 168,000-ton project for key battery materials and the 200,000 tons per year battery recycling project, forming a complete closed loop for the production, recycling, disassembly, and reuse of new energy batteries. The project processes 100,000 tons of used power batteries and similar materials per year. It produces 18,301.5 tons of ternary black powder per year, 5,589 tons of lithium iron phosphate black powder per year, 24,000 tons of ternary batteries suitable for reuse per year, and 9,000 tons of lithium iron phosphate batteries suitable for reuse per year ； By-product copper granules: 4,645.2 tons per year; aluminum granules: 2,499 tons per year; steel shells (magnetic metals): 3,425 tons per year, etc. Once the project is completed and put into operation, it is expected to generate an annual output value of 1.8 billion yuan, with annual tax payments of 25 million yuan. The 2,000-ton per year SPU production project in the Green and Low-Carbon High-End Materials Demonstration Park of Gongtou Group is funded and constructed by Shandong Zhenxixin New Materials Technology Co., Ltd. in collaboration with Lianyungang Duzhong Xino Aminlon Co., Ltd. The total investment amounts to 1.1 billion yuan, and the project covers an area of about 100 mu. The project mainly involves the construction of factory buildings and storage facilities covering an area of about 70,000 square meters, as well as the acquisition of high-efficiency polymerization reactors, spinning, and component molding equipment, to achieve a production capacity of 2,000 tons of SPU. SPU is currently the most resilient synthetic material, primarily used in fields such as aerospace and military industry, transportation, mechanical components, and sports shoes and apparel. Once the project is completed and put into operation, it is expected to generate an annual output value of 1 billion yuan, with annual tax payments amounting to 93 million yuan.
