Carbon dioxide capture potential of industrial by-products for post-carbon society

To contribute to the realisation of carbon neutrality by 2050, the authors have focused on the fact that some of the by-products of social activities have the ability to fix carbon dioxide and have envisioned the creation of a carbon dioxide capture urban environment using these materials. Also, the authors have emphasised carbon dioxide capture capabilities of industrial waste disposal facilities named as ‘Disposal Facility CCS’, since these are where substances containing large amounts of free calcium accumulate. As described herein, the authors have emphasised several kinds of by-product as carbon dioxide capture materials and proposed datasets of these carbon dioxide capture capabilities by measurement using constant flow aeration type carbon dioxide fixation testing, which we developed. Furthermore, using these datasets, the authors estimate the potential carbon dioxide capture capability of a specific industrial waste disposal facility as an example of ‘Disposal Facility CCS’ and demonstrate its relative effectiveness compared with that of forests. Furthermore, the authors estimate the carbon dioxide capture potentials of industrial by-products generated in Japan as some examples. Consequently, this study proposed carbon dioxide capture future society concept using carbon dioxide fixation materials on the basis of the estimation results conducted in this study.
