News from our newspaper In the context of "Carbon Peak, Carbon Neutral " , in order to fully fulfill corporate social responsibility and promote the green development of the cement industry. In view of the current situation that the emission of CO2 in the production process is difficult to be utilized, the bulk waste residue is difficult to be eliminated, and the added value of traditional utilization methods is low, Daye Jianfeng Cement Company actively carries out school-enterprise cooperation and cooperates with Southeast University to explore new carbon capture, storage and utilization technologies to promote the resource utilization of CO2 and industrial waste residue.
This project is jointly carried out by Daye Peak and Professor Qian Chunxiang's team from Southeast University. The aim is to fix CO2 in kiln tail flue gas by using microorganisms to cooperate with industrial waste residue, and to prepare high-quality new auxiliary cementitious materials in batches to realize efficient utilization of CO2 at normal temperature and pressure. As the first demonstration application project in China to prepare carbon-fixing auxiliary gelding materials using cement kiln tail flue gas CO2 , the research and development results can provide a new way for carbon capture and utilization in the cement industry, which is original. In order to ensure the smooth progress of the experimental project, daye peak and Southeast University team have completed the whole process design, equipment construction and installation of cement kiln tail flue gas capture, maintenance and monitoring. 10 January 28 , with the first batch of steel slag powder into the experimental device, marking the official start of the experimental project.
