Cement is the ballast stone of our business. We have put into operation 374 new dry process cement production lines, with a cement capacity of 520 million tons and a commercial concrete capacity of 450 million tons, both of which rank first in the world. Our business covers 25 provinces, cities and autonomous regions across the country. With our listed company Xinjiang Tianshan Cement Co., Ltd. (stock code: 000877) as the main body, we have created a listed cement company with the largest business scale in the world and a market value of over 100 billion yuan through business integration.
In the development process of the cement industry, we have actively taken the lead in the supply-side structural reform of the industry, explored an innovative development pathway through merger and reorganization, revitalizing existing assets and reducing the burden on ensuring sustainable development, built a "high-end, intelligent and green" world-leading industrial system, and strived to build an environment-friendly industry and deliver a modern city standard through the implementation of the "cement +" development strategy.
We deeply understand the relationship between enterprises and nature, and society, and are committed to safeguarding the green home, urban ecosystem, lucid waters and lush mountains, and people’s health. We have implemented a large number of successful green practices both at home and abroad, and built a number of factories in gardens, in forests and on grasslands. We have achieved a technological breakthrough in co-processing municipal waste and hazardous waste in cement kilns. As of the end of 2021, we have put into operation 44 production lines to co-process wastes using cement kilns, with an annual processing capacity of 4.22 million tons, theoretically reducing landfill land by 1,055 mu, and solving the big and difficult problem of urban ecological governance. Focusing on the carbon peaking and carbon neutrality goals, we vigorously develop power generation utilizing waste heat from cement kilns, use alternative raw materials, and try out technologies such as carbon capture, utilization and storage to create new values with huge application scenarios.
We are persistent in the pursuit of intelligent and high-end development. Guided by intelligent manufacturing, we continue to promote industrial digitization. Currently, we have developed a number of information technologies with independent intellectual property rights, and have built 11 intelligent cement production lines to drive energy consumption and environmental protection indicators, and intelligent management to reach the world’s advanced level. We are committed to providing high-end products and personalized services for major projects. Our annual sales volume of special cement reach x tons. We have served many key national projects such as Wudongde Hydropower Station, Baihetan Hydropower Station, Three Gorges Dam, Gezhouba Hydropower Station, Sichuan-Shaanxi Highway and Chengdu-Chongqing Railway. Our low-heat cement has been used for the first time throughout the whole dam body in key national projects such as Wudongde and Baihetan hydropower projects, and our cement for nuclear power engineering has been widely used in Ling Ao, Daya Bay, Yangjiang and many other nuclear power plant projects.
We continue to improve our business model. The "cement +" model has shown strong vitality, generated revenues of nearly 60 billion yuan from aggregates, commercial concrete, etc., and brought huge economic and social benefits through co-processing of solid waste, hazardous waste and domestic waste.
