In recent years, Xishuangbanna has closely adhered to the goal of "carbon peak and carbon neutralization", promoted green development by manufacturing first, vigorously promoted the adjustment of energy consumption structure, and strived to form a high-quality, sustainable and dynamic green low-carbon development pattern in the industrial field.
Under the background of the global positive response to the "double carbon" goal, the green low-carbon industry has ushered in unprecedented opportunities for development. Huaxin Hongta Cement (Jinghong) Co., Ltd. has a new production line of 2000 tons of cement clinker decomposed outside the kiln by dry process, with an annual output of 1 million tons of cement.
With the increasing global attention to carbon emission reduction, the cement industry has become the focus of both challenges and opportunities. The problem of carbon emissions in the cement production process has always been an important problem restricting the sustainable development of the industry, how to constantly break their own record of energy efficiency? The magic weapon of energy saving and emission reduction of Huaxin Cement is "saving as much as possible". Lu Qicai, director of the Environmental Protection Technology Department
of Huaxin Hongta Cement (Jinghong) Co., Ltd., said: The sawdust we use now is mainly the floating materials of the power station and the leftover materials of the timber factory, including straw, green jujube branches and other combustible wastes. By using these things, we can replace 15% to 25% of coal . In terms of energy consumption, we can reduce the level of 11% to 12%. Our comprehensive energy consumption can reach the national secondary standard. It can reduce carbon emissions by 50000 tons a year. "
Since 2000, Huaxin Hongta Cement (Jinghong) Co., Ltd. has closely combined with the green and low-carbon development path of cement industry, continuously promoted cleaner production, adopted the best pollution prevention and control technology, and continuously optimized and improved the level of pollutant control.". Through the low-carbon development strategy of combining green cement manufacturing with co-disposal of alternative raw materials and fuels, the technology of co-disposal of alternative raw materials and fuels in cement kilns was vigorously promoted, low-carbon cement products were explored and developed, and the proportion of alternative fuel energy increased from 6% to 25%. According to Lu Qicai, the second phase of the company's project is still undergoing transformation, all using alternative fuels for cement calcination, which will reduce the carbon emissions of cement enterprises by about 40%, and their goal is to achieve 100% coal-free plants.
As one of the old cement plants in China, Huaxin Hongta Cement (Jinghong) Co., Ltd. is well aware of the importance of green development to raw material mines. As early as 2011, before the exploitation of raw material mines, the company compiled the Implementation Plan of Green Mine Construction. On the premise of running mines according to law, the company started from further standardizing management, improving the level of resource utilization and strengthening technological innovation to do a good job in land reclamation and mine geological environment protection. Lu Qicai said that the company will strictly adopt the principle of "reclamation while mining", that is, to open a section, reclaim a section, and carry out scientific greening through the use of multi-species optimization, the use of local species and other measures. At present, mango trees, litchi trees, phoenix flowers, grass seeds and other species have been planted. The mining area of the mine is 268 mu, and the reclamation area is 154 mu, with a reclamation rate of 57.46%. By building an ecological green mine, the sustainable utilization of the mine can be realized. The demonstration example
of Huaxin Hongta Cement (Jinghong) Co., Ltd. to green low-carbon sustainable development is also a vivid portrayal of Xishuangbanna's promotion of green manufacturing system construction. In recent years, Xishuangbanna has closely adhered to the goal of "carbon peak, carbon neutralization", driving green development by manufacturing first, and gradually building a green low-carbon industrial system. Ma Ning, Chief of Energy Conservation and Resources Comprehensive Utilization Section
of Xishuangbanna Bureau of Industry and Information Technology, said: "Our prefecture actively practices the new development concept, establishes a" double carbon "work development mechanism with the government as the leading factor, enterprises as the main body, projects as the carrier and parks as the platform, and promotes the transformation and upgrading of industrial structure from high carbon to low carbon and from low end to high end."
