The amount of construction and civil engineering concrete structures in Japan has increased rapidly since the 1950s, and the stock amount of concrete structures is currently at its peak. For the future, concrete demolition will increase. Therefore, by positioning the concrete block as an effective CCC raw material, we will build a resource recycling system that does not generate waste and can effectively absorb CO2 in the atmosphere at the stage of disposal. The main issues to be examined are shown below
- Survey of stock volume by structural type and application on buildings in Japan
- Survey of stock amount by application on civil structures in Japan
- Survey of accumulated toral amount of concrete for buildings and civil structures in Japan
- Survey of concrete rubble treatment methods and systems at construction sites, intermediate treatment plants, and final disposal sites in Japan
- Construction of resource recycling scenario based on CCC manufacturing technology and system
