Go to "green" and "carbon" to find a new way! Cement industry starts a new journey of low-carbon transformation

Facing the severe challenge of global climate change, the cement industry is shouldering the heavy responsibility of carbon reduction with high aspirations. The horn of carbon emission reduction has been sounded, and action is imminent. The cement industry must promote the green transformation with great force, cut off the high-carbon shackles with the sword of innovation, and open a new chapter of green development.

On October 24, the "2024 China Cement Double Carbon Conference and the 12th Energy Conservation and Environmental Protection Technology Exchange Conference" was held in Wuhu, Anhui Province. Gao Dengbang, President of

China Cement Association, Zhu Shengli, General Manager of Anhui Conch Group Co., Ltd., Lv Zhijian, President of Xinjiang Building Material Industry Association, Ma Weiping, Chairman of OCC, Jiang Dehong, Vice President and Chief Engineer of Tianshan Material Co., Ltd., Li Jian, Associate Researcher of China Academy of Environmental Sciences, and Fan Yueming, Professor of South China University of Technology. Hubei Century Xinfeng "

China Cement Association, said that in the face of increasingly severe environmental challenges, energy conservation and emission reduction have become our common responsibility. As the basic raw material industry of the construction industry, the green development of the cement industry is not only related to the long-term future of the industry, but also our commitment to environmental protection. In recent years, China's cement industry has made remarkable achievements on the road of high-quality development, achieving a qualitative leap and efficiency improvement. In this new historical period, achieving the goal of "double carbon" has become an unshirkable historical mission for our cement workers. We must continue to stand up to the tide, shoulder heavy responsibilities, unswervingly implement the concept of green and low-carbon development, and make unremitting efforts to achieve the goal of "double carbon" at an early date.

Gao Dengbang called on cement enterprises to actively participate in the cause of double carbon, dare to explore, dare to innovate, and be aggressive. While carrying out the mission of double carbon, it will transform the pressure of environmental protection into green power, and promote enterprises to achieve new breakthroughs in the transformation and development. The industry should closely integrate the development of enterprises with the concept of building a community of human destiny, achieve deeper mutual benefit and win-win situation, and help the cement industry achieve higher quality and sustainable development.

the State Inspection Group, stressed that the cement industry is facing the risk of rising costs under the background of the carbon market. For example, with the advancement of the carbon market, enterprises need to purchase carbon emission rights for the part exceeding their own carbon emission quotas, which will increase the operating costs of enterprises; In order to reduce carbon emissions, enterprises need to upgrade and transform production equipment and processes, such as adopting new energy-saving equipment and improving production processes. These technological upgrades and transformations require a large amount of capital investment, and the return on investment cycle may be longer.

However, even in the face of many difficulties such as the need for capital investment and the long way to go for carbon reduction, there are still many excellent cement enterprises taking the lead in the layout and setting an example.

Conch Focus on Carbon Reduction Action.". After the national "double carbon" goal was put forward, it immediately formulated and implemented the carbon peak, carbon neutral action plan and the "14th Five-Year Plan" energy saving and carbon reduction plan, and defined six specific carbon reduction paths and group carbon neutral road map, including energy saving and consumption reduction, fuel substitution, raw material substitution, carbon capture and utilization, and plant carbon sink. Conch plans to take the lead in achieving carbon neutrality for its subsidiaries in the eastern region by 2050; by 2060, non-fossil energy consumption will reach more than 80%, and the whole group will achieve carbon neutrality.

Conch will focus on tackling key scientific and technological problems of carbon emission reduction. To give full play to the comprehensive advantages of "industry-university-research fund", Anhui Cement Carbon Capture and Conversion Application Innovation Consortium, one technology innovation center and four joint laboratories for energy saving and carbon reduction have been jointly established, and three carbon research institutes and China Carbon Company have been established, thus forming a "double-carbon" R & D and transformation system of "multi-linkage and collaborative innovation".

At present, Conch is relying on the above innovation system to accelerate the research and development of more cutting-edge carbon emission reduction technologies from the aspects of source emission reduction, process emission reduction and end emission reduction, and has also harvested a number of major scientific and technological innovations such as carbon capture, purification and utilization of cement kilns, carbon dioxide energy storage and so on, some of which are the first in China and even in the world.

Facing the heavy task of emission reduction, the cement industry has gathered various forces to promote technological innovation, management optimization and clean energy application, and jointly compose a magnificent chapter of green transformation. Ye Jiayuan, Vice President of New Cement Materials Institute of

China Building Materials Research Institute, pointed out that the future key technologies for carbon reduction in China's cement industry will mainly include: high energy efficiency firing, high efficiency grinding (roller press final grinding) technology and equipment; development, preparation and application technology of low-carbon cement system; Key technologies for pretreatment and calcination of alternative fuels (biomass) in cement kilns, oxy-fuel combustion in cement kilns and CO2 capture and utilization; Hydrogen and other zero-carbon energy burning cement and time are subject to quality, and the transformation is completed with high quality.". Seek truth from facts from top to bottom and strive for "four truths". That is, the leaders really attach importance to it, the capital is really invested, the project is really implemented, and the management level is really improved.

3. Enterprises carry out evaluation and monitoring in strict accordance with the requirements, and enterprises and evaluation institutions form a joint force to achieve "true" standards.

, innovation of production mode, In the future, the cement industry will move towards fully intelligent production, including intelligent logistics management, driverless system, digital mine application and other fields. Through technology integration, the data monitoring and intelligent optimization of the whole production process will be realized, and the overall competitiveness of enterprises will be enhanced.

3. Progress of environmental protection technology. Green low-carbon technologies such as carbon capture technology and new energy-saving technology will be vigorously promoted in the cement industry to reduce carbon emissions and environmental pollution, so that cement enterprises will become purifiers of the urban environment and promote the sustainable development of the whole industry.

In addition, Zhai Guanjie, Professor/Director of Fly Ash Research Institute of Dezhou University, shared the progress of geopolymer cement synthesis and near-zero carbon technology; Li Jin, Vice General Manager of Shanghai Environmental Energy Exchange, described the policy and practice of carbon asset management in cement industry; Lu Shoujiang, Vice General Manager of Shijing Science and Technology, introduced the application of carbon capture technology and shared its advantages; Zhang Lei, senior engineer of Shandong Institute of Engineering and Ceramics, gave a speech on the application of aerogel thermal insulation materials in cement industry.
