Dr. Oh and Dr. Kitagaki’s bottle method to evaluate CO2 uptake without chemical analysis equipments has been published in “Energy Reports”. It is often pointed out that the amount of CO2 fixed in concrete is invisible to those who are in charge of construction and waste management projects, so it is difficult for them to get a real feel for the amount of CO2 uptakes. Therefore, our group has devised a method that does not require chemical analyzers and can be qualitatively determined with simple equipment as well as “Visualization of CO2 absorption”. This method was originally proposed by Prof. Kenji Kawai of Hiroshima University and others in a committee of the Japan Society of Civil Engineers, and is based on “Sampling bag method” proposed by Prof. Kawai. We believe that it is possible to create a device with the minimum combination of techniques that a field engineer can use, up to a reasonably qualitative level.
Masuo Recycle Co. Ltd., Shimizu Corporation, and Japan Federation of Industrial Waste Management and Recycling Associations cooperated with us in the development of this evaluation device. Thank you very much for your support.
