summer, when you walk into Jiangxi Taihe Southern Cement Co., Ltd., you will see clean and tidy roads, tree-lined factories, birds chirping and insects chirping, accompanied by the sound of machines, playing a unique factory symphony. In recent years, Taihe Nanfang has actively implemented the "double carbon" strategy, unswervingly taken the road of ecological priority and green development, made great efforts in carbon reduction, pollution reduction and green expansion, and made new progress in promoting green and low-carbon development. On the basis of provincial water-saving enterprises, provincial green factories and provincial green mines, it has added the honor of "waste-free enterprises" in Ji'an City. Make good use of
"intellectual materials": the main type of rock in the zero waste
cement mine is limestone, while the aggregate mine can use a variety of ores. From the product point of view, cement production requires high chemical composition of limestone, and aggregate production requires certain compressive strength of ore, which determines that aggregate and cement can complement each other to utilize mineral resources. Faced with the complex and changeable rock composition and geological structure of the mine, in order to improve the comprehensive utilization rate of mineral resources, Taihe Nanfang has worked in a multi-pronged manner to make a good overall plan for mining, make the best use of everything, and realize the utilization of resources without waste. With the implementation of mine source control and production scheduling, the comprehensive utilization rate of mine stripping has maintained "zero" discharge of waste rock for three years, and the comprehensive utilization rate of waste rock has reached 100%. The use of each ore has been brought into full play, and the "waste-free mine" has been truly achieved. Taihe Nanfang practices the concept of "green water and green hills are Jinshan and Yinshan", implements "mining and stripping simultaneously, while mining and greening", and continuously promotes the construction of green mines step by step and in stages, so as to achieve "protection in development and development in protection". In September 2024, Huanggang Limestone Mine was successfully selected into the list of green mines in Jiangxi Province.
Change "waste" into "treasure": The production of zero discharge
of waste residue commercial mixing and aggregate enterprises will produce waste residue and other by-products in the production process, how to effectively use these by-products is the difficulty for commercial mixing and aggregate enterprises to tackle key problems. Taihe South strengthens fine management, optimizes production process, reduces the amount of waste residue produced in the production process, and achieves self-absorption of production waste residue. Give full play to the advantages of integrated management, so as to achieve "three lines in one, waste does not go out of the factory". Through formula optimization, cement, aggregate, commercial mix production cycle linkage, realize the recycling of waste, change waste into treasure, achieve no waste of resources, zero emission of waste residue, win-win economic and environmental benefits. It is a vivid practice of comprehensive utilization of resources to turn by-products and wastes of one production process into raw materials of another process, from a one-way street relying on resources to a multi-chain realizing the primary utilization of resources, to eat up and squeeze out raw materials and form an internal cycle of enterprises.
Comprehensive utilization: The enterprise with zero waste
of industrial waste residue, guided by innovation, has increased investment in technology research and development, and the self-developed "a concrete preparation device for limestone powder instead of fly ash" and other utility model patents have been popularized and applied. While optimizing the production process and reducing the generation of waste in the production process, we should aim at the consumption of industrial solid waste and mine tailings, take the co-disposal of multi-source waste in cement kilns as the core, promote the use of alternative raw materials and alternative fuels, and promote the application of technology transformation. Taihe South has passed the national low-carbon product certification and product carbon footprint evaluation certification successively, making the "grey" industry become "green" products.
Reduce waste and increase gold, reduce carbon and increase green. Taihe South will continue to adhere to the concept of green development and guide the whole staff to actively participate in the construction of ecological civilization and green development.
