Recently, General Secretary Xi Jinping pointed out in the 11th collective study of the 20th Political Bureau of the Central Committee that "green development is the background of high-quality development, and new quality productivity itself is green productivity.". We must speed up the green transformation of development mode and help carbon reach the peak of "carbon neutralization". General Secretary
Xi Jinping's important exposition and the deployment requirements of the Third Plenary Session of the CPC Central Committee have profoundly clarified the strategic path of the construction of ecological civilization. Increasing the "green" content, reducing the "carbon" content, and enabling the construction of beautiful China with green and low-carbon development are the proper meaning and important ways to promote Chinese-style modernization. Under the guidance of the
double carbon target, green transformation has become a new trend of the times. In March
this year, Shijing Technology won the title of "Top 100 ESG Listed Companies in China 2024" for its outstanding performance in the field of sustainable development. This award is not only an affirmation of its past efforts, but also an ardent expectation for its future development. As a scientific and technological environmental protection enterprise, Shijing Science and Technology actively responds to national policies, takes scientific and technological innovation as the driving force, practices the concept of green development, and devotes itself to protecting our common beautiful homeland.
Data show that after years of development, Shijing Science and Technology has made remarkable achievements in the field of environmental protection and green low-carbon development, forming unique technological advantages. Its independent innovation and development of "steel slag + carbon dioxide = active cementitious material" is one of the best answers for Shijing Science and Technology to drive green development by technology.
Steel slag is a by-product in the steelmaking process, and its output is about 10-15% of crude steel. As a big iron and steel country, China produces more than 100 million tons of steel slag every year. Taking 2024 as an example, the output of steel slag in China increased from 123 million tons in 2014 to 160 million tons, but the comprehensive utilization rate was less than 30%.
Improving the comprehensive utilization rate of steel slag and turning waste into treasure can not only improve the efficiency of resources, but also play an important role in promoting the green development of social economy.
Shijing Science and Technology has creatively developed the steel slag resource utilization technology of "steel slag + carbon dioxide = active cementitious material", which uses the dry method of steel slag to capture and utilize CO2 in situ, effectively solves the problem of poor stability of steel slag and improves its activity, and prepares the auxiliary cementitious material with high activity and carbon fixation. It has successfully solved the world problem of steel slag resource utilization. The
prepared active cementitious material can replace the application of cement in construction, reduce the consumption of cement, reduce the emission of pollutants and the consumption of resources.
Steel slag carbon capture has been widely used
in cement, steel and other industries as early as November 2022. The world's first steel slag capture cement kiln flue gas CO2 production line for carbon sequestration auxiliary cementitious materials and low-carbon cement, invested by Shijing Science and Technology, has been completed and put into operation.
The project has the production capacity of treating 300,000 tons of steel slag annually to prepare auxiliary cementitious materials for carbon sequestration, which can directly capture and utilize 16,000 tons of CO2 in cement kiln flue gas annually, and reduce about 250,000 tons of carbon in society. The operation of this project provides an important choice for promoting the low-carbon development of cement industry and realizing the unity of economic and environmental benefits.
In addition, the technology of using steel slag to capture CO2 from flue gas has been applied in many projects. In April
2023, the world's first use of steel slag to capture CO2 from lime kiln flue gas was completed and put into operation. Yongfeng Project has the production capacity of treating 300,000 tons of steel slag per year and preparing auxiliary cementitious materials for carbon sequestration, which can directly capture and utilize 16,000 tons of CO2 in lime kiln flue gas per year and 600,000 tons of high-efficiency composite mineral admixtures per year. On May 21,
2024, the formal signing of Baowu E Steel Carbon Capture and Industrial Solid Waste Resource Utilization Project, a landmark event of cooperation between Shijing Science and Technology and Baowu Group, not only indicates that the two sides have taken a solid step in exploring the deep cooperation in the field of industrial carbon reduction and resource recycling, but also marks that China's iron and steel industry is in the field of industrial carbon reduction and resource recycling. It is another milestone in the transformation of efficient emission reduction and sustainable development mode. According to the
data, the project is located in the plant area of Echeng Iron and Steel Co., Ltd. of Baowu Group, Ezhou City, Hubei Province. It is planned to invest 144 million yuan to build a 300000 tons steel slag pre-grinding system, a 300000 tons steel slag carbon capture system and a high-efficiency composite mineral admixture production system with an annual output of 1 million tons. After the project is put into production, the annual output of high-efficiency composite mineral admixture will be 1 million tons, which can directly capture and utilize 20000 tons of carbon dioxide, indirectly reduce the amount of cement clinker in cement and cement in concrete, and comprehensively reduce carbon by 250000 tons.
It is reported that Shijing Science and Technology and Baowu Huanke have reached strategic cooperation. Baowu Huanke is a specialized subsidiary of China Baowu in the environmental protection industry. The company takes the "3 + 3" combination as its main business, namely, three green material development businesses: metallurgical slag building materials, metallurgical dust and mud metallization, and iron oxide powder magnetization business; Three pollution reduction and carbon reduction services: full quantification of solid waste disposal, ecological soil remediation, and recycling of municipal solid waste, to build a third-party professional platform for environmental pollution control. The cooperation between Shijing Science and Technology and Baowu Huanke is bound to inject strong impetus into the future development of both enterprises.
It is worth mentioning that the steel slag carbon capture project of Shijing Science and Technology adopts BOT mode and adheres to the principle of "not selling equipment, sharing benefits", which not only demonstrates absolute confidence in its own technology, but also provides long-term and stable performance support for enterprises. Based on
technology to create the future
, Shijing Science and Technology always adheres to the concept of "people-oriented, customer first", constantly exploring and innovating, pragmatic and efficient.
In terms of helping to achieve the "double carbon target", Shijing Technology has also successfully developed and industrialized the industrial process CCUS technology in recent years, which is mainly aimed at key carbon emission industries such as thermal power, steel and cement, and has achieved effective control of carbon emissions through carbon capture and carbon conversion.
Data show that CCUS technology of Shijing Science and Technology has been applied in a large cement enterprise in China, and has achieved good application results. With the incorporation of cement industry into the national carbon emission trading market, domestic cement enterprises will face increasingly severe pressure to reduce carbon emissions, and CCUS has great potential.
Under the background of double carbon, the market of carbon reduction and carbon sequestration has a broad space in the future. Shijing Technology has obvious technological advantages in the field of carbon reduction and carbon sequestration, which is expected to provide a long-term and strong driving force for the development of enterprises.
In fact, in addition to "carbon", Shijing Technology also has strong strength in many environmental protection branches. Data show that up to now, the company's business scope covers waste gas treatment, wastewater treatment, chemical treatment and other key areas, in the solar photovoltaic industry waste gas treatment, Shijing Technology is the leader, occupying more than 70% of the domestic market share.
As an environment-friendly enterprise driven by technology, Shijing Science and Technology Enterprise has distinct characteristics, benefiting from the promotion of double carbon target and construction of ecological civilization, and is expected to gain a broader development space in the future.
