把有价值材料“吃干榨尽”让固废“物尽其用” 多视角解码传统产业绿色升级新成效

Core Viewpoint - During the "14th Five-Year Plan" period, China's industrial green and low-carbon development has made significant progress, with continuous improvement in legal policy systems and resource utilization levels [1][4]. Group 1: Energy Consumption and Resource Utilization - The energy consumption per unit of industrial added value is expected to decrease by over 13.5%, while the water consumption per ten thousand yuan of industrial added value is projected to decline by 25% [4]. - The comprehensive utilization rate of major industrial solid waste has reached 57%, and the output value of national green factories has increased from 9% to over 22% of total manufacturing output [4]. - Over 8,000 green factories and more than 600 green industrial parks have been cultivated, indicating a continuous improvement in the green manufacturing system [4]. Group 2: Green Manufacturing Practices - The green manufacturing level is continuously improving, with an expanding scale of green low-carbon technologies, products, and equipment supply [6]. - Traditional industries are undergoing green upgrades, with innovative management systems transforming waste from steel production into reusable resources [7]. - The company has developed a multi-energy complementary energy matrix, utilizing recovered gas to generate electricity and integrating solar power [8]. Group 3: Waste Management and Recycling - The company has achieved zero wastewater discharge through advanced treatment processes, effectively recycling over 40,000 tons of wastewater daily [9]. - Solid waste is repurposed into materials for 3D printing, contributing to the construction of eco-friendly infrastructure [9]. - The company has implemented over 200 energy-saving and emission-reduction projects, resulting in a nearly 60% reduction in sulfur dioxide and nitrogen oxide emissions [12]. Group 4: Battery Recycling Innovations - The company has developed a discharge-free dismantling process for used power batteries, significantly reducing pollution and enhancing material recovery rates to over 95% [15][17]. - The recycling process allows for the extraction of valuable materials such as lithium and iron, with carbon emissions from lithium production being reduced by 67% compared to traditional methods [17]. - By 2025, the comprehensive utilization of used power batteries is expected to exceed 400,000 tons, marking a 32.9% year-on-year growth [19]. Group 5: Green Treatment of Living Pollutants - A power plant in Anhui has successfully transformed problematic sewage sludge into usable fuel resources, integrating it into the fuel management system [21][22]. - The new treatment process eliminates solid waste discharge and secondary pollution, achieving significant reductions in carbon dioxide emissions [24]. - The plant has processed approximately 185,000 tons of sludge, generating around 43 million kilowatt-hours of electricity and achieving a revenue of 60 million yuan from co-firing [24].
