On June 5, a meeting of the vice-chairperson and the expanded expert committee of the Inorganic Silicides Branch of the China Inorganic Salt Industry Association was held in Xuancheng, Anhui. Zhang Fushun, head of the branch’s expert committee, summarized the work for the 2024–2025 period at the meeting and outlined the work plan for the expert committee for the 2025–2026 period. Zhang Fushun noted that during 2024–2025, significant progress was made in the development and application of new green, low-carbon technologies, processes, and equipment in the inorganic silicide industry. Carbonization-based production methods, such as using rice husk ash as a silicon-based material instead of quartz sand to produce silica, as well as using carbon dioxide instead of sulfuric acid or hydrochloric acid for the same purpose, have seen substantial improvements in terms of product quality and processing techniques. Companies such as Silicochemistry, Shandong Lianke Technology, Fujian Nanping Yuanli, and Fujian Sanming Zhengyuan are at the forefront in this field. The industry has achieved significant progress in energy conservation, emission reduction, as well as safety and environmental protection. Members of the expert committee play an important role in their respective companies, and through advanced technologies and equipment, further optimization and upgrading are carried out to achieve \"one increase and one decrease\". The new projects adhere to principles and concepts such as full-life-cycle design for green products, design for recycling and reuse, and designs aimed at reducing raw material and energy consumption. They promote source reduction, optimized integration of production processes, as well as the reuse of waste and its conversion into resources, thereby enhancing the overall level of carbon reduction in the industry. Companies such as Guangdong Huilte, Hubei Jiangs, Lingwei Technology, Fujian Tongsheng, Nanping Yuanhe, Sanming Fengrun, Shandong Xiangli, and Shunding Atek have made sustained efforts over a long period of time, achieving significant results. Companies with advantages in tooling equipment and related resources are actively expanding into the inorganic silicon industry, leveraging their strengths in technology development, industrial applications, and energy resources to make new progress. Speaking about the plans for 2025–2026, Zhang Fushun noted that priority should be given to the inorganic silicide industry, which, under the guidance of the dual-carbon goals, needs to advance in areas such as technological innovation, intelligent manufacturing, and green, low-carbon development. This will help to improve the industry’s structure and level, ensure safety and environmental protection, and foster new forms of productive capacity, thereby lifting it to a new stage of high-quality development in terms of technology, quality, and management. Continue to pay attention to and promote technological advancements in using carbon dioxide as a substitute for sulfuric acid and hydrochloric acid, striving toward a transformation toward green, low-carbon, and sustainable development processes. Pay attention to relevant pollution developments in this industry, as well as the formulation, establishment, and revision of policies, regulations, and standards. Prioritize technical work, and strive to establish reasonable, appropriate, and feasible emission targets to avoid severe constraints on the development of the industry and its products after implementation, which could lead to problematic situations. Secondly, in line with the requirements of the 15th Five-Year Plan and under the guiding principle of \"reducing carbon emissions, cutting pollution, expanding green spaces, and promoting growth,\" it is necessary to balance supply according to market demand, so as to enable leading enterprises to fully utilize their production capacity, while effectively phasing out some excess, inefficient, and outdated production capacities. Strengthen the supporting role of talent, drive innovation, control carbon emissions, and further enhance the industry’s overall technical advantages. Strive to organize 1-2 on-site observation and technical evaluation activities throughout the year. In terms of energy conservation and environmental protection, we will continue to be guided by the dual-carbon goals to develop green production processes. In response to the technical challenges and needs of member enterprises in terms of clean production processes, energy conservation, pollution reduction, and efficient use of resources, the adoption of energy-saving and water-saving equipment is promoted, the reuse rate of water in industrial processes is increased to reduce water consumption, and issues related to wastewater discharge are further addressed. Through new technologies, equipment, and methods, compliance with environmental standards is ensured in an effective manner, and demonstration projects for comprehensive water conservation are promoted. Drive the industry toward a new type of industrialization characterized by high technological content, low resource consumption, low emissions of waste, and good economic benefits. At the same time, it is necessary to carry out fundamental tasks such as industry standardization and technical regulations, and actively organize the development of group standards that meet market demands and development trends. Collaborate with relevant departments to carry out the revision and review of industry standards and **standards. Giving play to the important role of industry associations in the process of transformation and upgrading, and addressing the new problems and contradictions faced by small and medium-sized enterprises in their development, is the direction for progress in the coming period. Specialized studies are carried out actively, organized in groups; through on-site sessions, video conferences, lectures, and field visits, the production processes and current status of various types of inorganic silicides, as well as the development trends of high-end, sophisticated products, are examined as specific topics. At least 2 sessions are planned to be held throughout the year. It is planned to organize 2 thematic research activities and safety-related events.
