Hi, a new paper has been published in the Journal of Cleaner Production. Using statistical data since Japan began producing cement in the modern era, the study estimates the lifespans of various types of structures and quantifies the total CO2 fixed within these concrete structures. The model incorporates not only the impact of lifespan but also data on the surface area-to-volume ratios of structures, which were aggregated based on architectural drawings, taking into account the effects of Japan’s seismic design regulations and changes in legislation.

Additionally, the model integrates the influence of local environments, finishing materials, and post-demolition scenarios. By using this model, we aim to further evaluate the potential impact on the industry by incorporating future trends in the cement industry and material development.

While this paper takes a slightly different approach from previous materials research in our lab, we plan to continue working on studies that link material flow and CO2 assessments with material development to provide a comprehensive overview of the situation in Japan.

The paper is open-access and freely available for you to read.
