Abstract
In order to reduce greenhouse gas emissions, Taiheiyo Cement Corporation implemented the Development of Carbon Circulation Technology for the Cement Industry, a project subsidized by the New Energy and Industrial Technology Development Organization (NEDO), from July 2020 to March 2022. In this project, we have developed a series of technologies for carbon recycling from CO2 capture from cement kiln exhaust gas to effective utilization of the recovered CO2 in recycled construction waste and cement/concrete products. This paper gives an overview of the subsidized project.
