走进广西贺州市平桂区碳酸钙产业一线，便能看到上述景象。"十四五"以来，依托"中国重钙之都"的资 源优势，该区推动碳酸钙这一传统产业向绿色化、智能化转型升级，通过技术革新、装备升级与产业链 延伸，激发新质生产力，走出了一条生态与经济双赢的高质量发展之路。 中新网广西贺州1月26日电(麦炜 张然然 姚启雯 张广权)机器轰鸣的生产车间内，几乎不见粉尘飘散，只 有密封管道内物料流动的细微声响；曾经裸露的矿山开采区，如今已是阶梯覆绿，草木葱茏，与周边青 山融为一体。 图为广西 贺州市宝利丰矿业有限公司的生产车间。姚启雯 摄 图为广西 长鸿生物材料有限公司全生物可降解热塑性塑料产业园。广西长鸿生物材料有限公司供图 这种"生态+产业"的融合发展模式，是平桂区"十四五"期间着力延链、补链、强链的生动实践。目前， 平桂区已初步形成从矿山开采、板材加工，到废料回收制备超细粉、合成人造岗石，再到高端新材料产 品的闭环式全产业链，真正做到了"一石多吃、吃干用尽"的资源循环最大化。 2025年，平桂区规模以上碳酸钙企业实现产值123.1亿元，占全区规上工业总产值的42.3%；全年新增规 上工业企业30家，总数达241家，并形成了碳酸钙 ...

Group 1 - The core theme of the discussion is to enhance the high-quality development of the calcium carbonate industry in Yulin City, focusing on attracting environmentally friendly leading enterprises to drive the entire industry chain upgrade [1][2] - The region has the largest high-quality limestone mine in South China, with proven reserves exceeding 20 billion tons, but faces challenges such as a high proportion of primary products and weak deep processing capabilities [2][3] - The local government aims to implement a comprehensive planning strategy that includes collaboration with logistics and port facilities to promote the calcium carbonate industry, emphasizing the introduction of high-value-added enterprises [2][4] Group 2 - Companies are encouraged to establish research and development centers and collaborate with universities to tackle key technologies in the calcium carbonate sector, promoting ecological development [3][4] - The introduction of intelligent equipment and AI algorithms is suggested to optimize production processes and enhance energy efficiency, with some companies already investing significantly in advanced dust removal and wastewater treatment technologies [3][4] - The establishment of a strong brand for "Xingyi Calcium" is deemed essential, with plans to create quality standards and participate in national trade fairs to increase market visibility [4][5] Group 3 - The local government is enhancing financial support for the calcium carbonate industry, having coordinated loans of 1.4 billion yuan for over 20 enterprises this year [6] - Investments exceeding 300 million yuan are being made in the construction of standardized factories and the development of AI-enabled smart parks, aiming to create a demonstration base for intelligent manufacturing [6][5] - The goal is to achieve a calcium carbonate output value of 2.5 billion yuan by 2024, with products targeting markets in the Guangdong-Hong Kong-Macao Greater Bay Area and Southeast Asia [4][6]

Core Viewpoint - The transformation of Yongfeng County's limestone mining industry from low-value raw material extraction to high-end manufacturing of nano-calcium carbonate has created a billion-dollar industry, showcasing significant advancements in technology and sustainability [1][2][3]. Group 1: Industry Transformation - Yongfeng County has a limestone reserve of 11 billion tons, ranking third in the country for calcium carbonate content, with a high whiteness and low iron content [2]. - Before 2008, the county's mining operations were characterized by disorganized small-scale enterprises with a resource utilization rate of less than 50% [2]. - The introduction of policies in 2008 led to the closure of over 50 illegal mines and the elimination of more than 100 outdated production facilities, increasing resource utilization to 90% [2][3]. Group 2: Technological Advancements - The establishment of a carbon calcium industry research institute in 2024 has fostered collaboration between enterprises and over 20 research institutions, enhancing innovation [3]. - Companies like Jiangxi Guangyuan Chemical have developed intelligent production lines that reduce dust emissions by 60% compared to traditional methods [3]. - The county has seen 127 patents granted and a technology investment ratio exceeding 8%, significantly higher than traditional manufacturing [3]. Group 3: Supply Chain Development - The establishment of a complete industrial chain in Yongfeng allows for local procurement of 90% of raw materials, reducing costs by over 20% [4][5]. - Jiangxi Guangyuan Chemical, as a leading enterprise, has attracted over 50 supporting companies to the region, enhancing the local economy [5]. Group 4: Environmental Sustainability - The implementation of a wastewater recycling system has achieved a 95% reuse rate, and dust collection efficiency has improved by 40% [6]. - The county has adopted a "smart mining" system for real-time monitoring of extraction and environmental indicators, contributing to its recognition as a national base for comprehensive solid waste utilization [6].
