推动化工行业减污降碳协同创新——南通经济技术开发区打出绿色“组合拳”

Core Viewpoint - The Nantong Economic and Technological Development Zone is committed to green development, focusing on pollution reduction and carbon emission control, while enhancing the ecological environment and promoting the green transformation of the chemical industry [2][3]. Group 1: Green Transformation Initiatives - The development zone has implemented a comprehensive plan with 45 enhancement projects targeting the chemical industry, focusing on raw material substitution, process improvement, and clean production [4]. - Notable projects include the IDA glyphosate clean production transformation, which recycles 640,000 tons of glyphosate mother liquor, recovers 12,500 tons of phosphorus products, and reduces carbon emissions by 32,000 tons annually [4]. - By 2024, the development zone has completed 34 projects, optimizing product structures and eliminating approximately 37,000 tons of high-pollution chemical capacity, resulting in a reduction of wastewater discharge by 1.4 million tons and hazardous waste by 2,000 tons [5]. Group 2: Regulatory and Management Enhancements - The development zone has established a collaborative mechanism among multiple departments to enhance pollution reduction and carbon emission management, ensuring a systematic and refined approach [3]. - New chemical enterprises must meet international advanced standards in process, equipment, energy efficiency, and pollution prevention, with over 40% of new projects achieving benchmark energy efficiency levels [5]. Group 3: Spatial Optimization and Resource Circulation - The development zone is optimizing its spatial layout by relocating chemical enterprises to reduce land use by 3.7 square kilometers, which is expected to achieve an annual carbon reduction of 220,000 tons [7][8]. - The establishment of a green raw material supply network and the construction of a compressed air pipeline are projected to reduce carbon emissions by 10,000 tons annually [9]. - The development zone aims to create a "zero-waste park" by promoting the deep processing and efficient utilization of by-products, with companies achieving significant reductions in hazardous waste generation and carbon emissions [10][11].
