The 9th National Nonferrous Metals Ecological Environment Protection Conference was held in Zhengzhou from June 27 to 28, 2025, hosted by the China Nonferrous Metals Industry Association and the China Nonferrous Metals Society. It is reported that the theme of this conference is "Protecting Green Waters and Green Mountains and Forging the Future of Nonferrous Metals", aiming to deeply study and implement the spirit of the 20th National Congress of the Communist Party of China and Xi Jinping's ecological civilization thought, firmly establish and practice the concept that green waters and green mountains are gold and silver mountains, promote the continuous improvement of ecological environment quality, and achieve high-quality development of the nonferrous metal industry.

Li Yingwu, general manager of the product center of Zhengzhou Jingwei Technology Industry Co., Ltd., delivered a keynote speech entitled "Research on the Harmless Treatment and Resource Utilization Technology of Aluminum Electrolytic Carbon slag" at the conference. He gave a detailed introduction to the conference on the company's technical exploration and practice in the treatment of hazardous solid waste in electrolytic aluminum in recent years and successful application cases. As early as 2010, Jingwei Technology began to study and apply the technology of harmless treatment and resource utilization of hazardous solid waste in the electrolytic aluminum industry. It is a leader in hazardous solid waste treatment technology in the domestic electrolytic aluminum industry. It can effectively solve the problem of hazardous solid waste treatment generated in the production process of electrolytic aluminum, turn waste into treasure, and realize the harmless treatment and resource utilization of hazardous solid waste. Since the promotion of this technology, it has been successfully applied by many customers such as Oriental Hope, Inner Mongolia Chuangyuan, Xinjiang Shenhuo, Yunnan Aluminum Haixin, etc.

In addition to this technology, Jingwei Technology has also combined its own customer advantages and technological advantages to form a business development model driven by energy conservation and environmental protection, and intelligent manufacturing. It has launched a number of industry-leading products such as high-temperature backing systems, special welding systems for ultra-large cross-section conductors, fluoride salt feeding vehicles, detection devices, and intelligent complete systems. The main products can cover the entire process of electrolytic aluminum production, including the installation, startup, operation, maintenance, disassembly, and environmental protection treatment of solid waste from electrolytic cells.

This non-ferrous metal ecological environment protection conference not only discussed the technical achievements of the non-ferrous metal industry in ecological environment protection, but also provided an important communication platform and policy guidance for the industry's scientific and technological innovation, green and intelligent development. Through this conference platform, the company not only demonstrated the scientific and technological innovation achievements in the electrolytic aluminum industry over the past two decades, but also strengthened communication and exchanges with other enterprises in the industry, which will surely promote the company's continuous exploration and innovation in the fields of greening and intelligence.
