The first 10,000-ton-scale CO2 mineralization demonstration project in the coal chemical industry began trial operation. Author/Source: Huahua Net Coal Chemicals. Date: 2022-06-03. Clicks: 22. Recently, the Institute of Organic Functional Materials and Application Technologies, in collaboration with Zhongyan Anhui Hongsi Fang Co., Ltd., Tongji University, and Jiangsu Tongcui He Technology Co., Ltd., successfully launched trial operation of China’s first 10,000-ton-scale CO2 mineralization project aimed at producing fully solid-waste-based negative-carbon building materials. This project utilizes bulk solid wastes generated in the coal chemical industry’s production process, such as gasification slag, calcium carbide slag, and fly ash, to undergo a mineralization reaction with the CO2 emissions produced by this industry, without the need for any external heat source or cement. As a result, high-strength building materials with a high carbon sequestration rate and negative carbon emissions are produced, thereby achieving a combination of energy savings, waste utilization, and negative carbon emissions. Achieving \"carbon peak and carbon neutrality\" serves as a powerful driving force and catalyst for industrial structure adjustment. It not only imposes more urgent demands on such adjustment but also offers significant strategic opportunities for the optimization and upgrading of the industrial structure. “The energy resource characteristics of \"abundant coal, limited gas, and scarce oil\" determine that China’s energy structure is dominated by coal. With the goal of \"carbon neutrality\" serving as a strict constraint, efforts are being made to accelerate the low-carbon transformation of traditional industries, to develop a new type of green and low-carbon economy, to promote structural adjustments and upgrades in the industry sector, to reduce energy consumption and carbon emissions in industrial activities, and to gradually achieve decoupling between economic growth and carbon emissions. Industrial carbon emission reduction is of paramount importance in achieving the goals of carbon peak and carbon neutrality. The coal chemical industry is one of the six industries with high energy consumption, and its development faces increasing constraints due to environmental and resource limitations; therefore, it is urgent to seek technological innovations and a low-carbon transformation for this industry. The Institute of Organic Functional Materials and Application Technologies has always focused on technological innovation as its core, striving to become an advocate of low-carbon concepts, a practitioner of low-carbon policies, and a leader in low-carbon development. It implements the \"dual carbon\" strategy in the low-carbon development of enterprises, and actively explores new ideas, technologies, and approaches for the synergistic treatment of large-scale solid waste and carbon dioxide. Following numerous preliminary application studies and thorough preparations, and with the full support of leaders and experts such as Ling Huixun, Chairman and General Manager of Zhongyan Anhui Hong Sifang New Building Materials Technology Co., Ltd., as well as the concerted efforts of all parties involved, the project is now ready for trial production. Cheng Mingzhao, Assistant Director of the Functional Materials Research Institute and Executive Director of the Environmental Protection Center, Dr. Li Chen from the School of Materials Science and Engineering at Tongji University, Ouyang Zhenkui, General Manager of Jiangsu Tongcui He Technology Co., Ltd., along with other relevant officials and professional technicians, were all involved throughout the trial production process of the mineralization line. The trial operation of \"the first domestic coal chemical industry project for the production of full-solid-waste, carbon-negative building materials via CO2 mineralization on a scale of 10,000 tons\" was successfully completed, with excellent results achieved. Verified through pilot-scale production, this project combines advanced technological innovation with engineering feasibility. Industrial solid waste and CO2 gas can undergo mineralization reactions to produce mineralized building materials without the need for any external heat source or cement, and the strength, durability, and other properties of these materials meet current ** and industry standards ； At the same time, it also enables efficient capture and utilization of CO2, with an average carbon sequestration rate of over 15%, truly achieving a combination of energy savings, waste utilization, and carbon reduction. The successful trial operation of this project holds great significance for the low-carbon and sustainable development of the coal chemical industry and other high-carbon-emission industries in China; it not only saves the energy required for the production of products derived from solid waste recycling but also significantly reduces production and operational costs ； It simultaneously achieves low-cost and efficient capture and utilization of CO2 from coal chemical industry flue gases, finds the optimal solution to the equation \"X solid waste + Y carbon dioxide = negative-carbon building materials\", fills a gap in both international and domestic industries, and effectively sets a precedent in this field. The core technology employed in this project originates from the research team led by Professor Jiang Zhengwu at Tongji University. This team has been engaged for a long time in scientific research and technological development related to the use of solid waste for the production of negative-carbon green materials. Their independently developed CO2 mineralization technology uses bulk solid wastes with mineralization capabilities as primary raw materials; through the synergistic activation of various solid wastes, along with efficient transmission and in-depth mineralization of CO2, it is possible to significantly improve the performance of the resulting products as well as their carbon sequestration capacity. This technology enables the effective utilization of carbon dioxide from industrial exhaust gases at various concentrations ； The gelling components of the product are entirely made from industrial solid waste, and no external heat source is required in the production process. By developing such new types of negative-carbon building materials, it is possible to achieve the simultaneous treatment of large amounts of solid waste and CO2 emissions from industries such as chemicals, steel, metallurgy, and power generation. This approach helps to address the challenges related to the harmless disposal and resource utilization of such solid waste, as well as the difficulties in effectively capturing and utilizing CO2 from industrial emissions. Building on this research, the Functional Materials Research Institute has entered into in-depth cooperation with Professor Jiang Zhengwu’s team from Tongji University to carry out the commercialization and pilot-scale testing of the core technologies for solid waste mineralization. As a result, an industrial production process as well as the corresponding set of equipment for using pure solid waste to capture and mineralize carbon dioxide in order to produce negative-carbon building materials have been developed, thus creating a comprehensive solution for the entire process. At present, this solution enables the combined treatment of solid wastes with high mineralization activity (such as calcium carbide slag, steel slag, phosphorus slag, manganese slag, etc.) and those with low mineralization activity (such as fly ash, gasification slag, foundry sand, construction waste, etc.). It allows for the mineralization of CO2 from industrial flue gases under various conditions of temperature, pressure, and concentration, resulting in a range of high-value products such as wall materials, recycled aggregates, materials for municipal roads, and ecological slope protection structures. These products are widely used in sectors such as municipal engineering, construction, and water management, enabling the transformation of inexpensive waste into high-value goods. This approach truly achieves low-carbon emission throughout the entire life cycle of solid waste-based products, from the raw material stage to their application stage. Building on the successful trial operation of this project, the Institute of Functional Materials and Anhui Hongsi Fang New Building Materials Technology Co., Ltd. are also actively planning the renovation and construction of carbon dioxide pipelines, in order to make full preparations for the official commissioning of the project aimed at capturing and utilizing CO2 from large amounts of solid waste. Upon completion of the renovation, this project is expected to be able to handle nearly 1 million tons of various types of bulk solid waste each year. At the same time, it will capture and utilize at least 100,000 tons of CO2, which is equivalent to the carbon sequestration capacity of 100,000 mu of forest area per year, or the same as eliminating the emissions from nearly 60,000 economy cars for one year. Once it is put into formal operation, this project will serve as a model for low-carbon transformation in China’s coal chemical industry, and it will also mark a significant milestone on the path toward low-carbon, green, and circular development for this sector in our country At the same time, the Institute of Functional Materials will continue to work actively with various parties to promote low-carbon and sustainable development paths as well as comprehensive solutions for other high-carbon-emission industries such as the power sector, steel industry, and cement industry, thereby contributing to the early achievement of China’s \"dual carbon\" goals!
