Abstract
Member companies of the Japan Environmental Facilities Manufacturers Association is working on CCUS at waste incineration facilities in order to move toward achieving carbon neutrality by 2050. In order to understand the carbon dioxide recovery process for flue gas, this study first presents examples of the chemical absorption method, some commercial facilities in operation, and application of the carbon dioxide-capture process at waste incineration facilities. Secondly, the paper looks at the equipment at a facility of the Saga City Waste Disposal Center that has been operating since 2016 and is the world’s first attempt at capturing and utilizing carbon dioxide from flue gas. Clean Plaza Fujimi, a center which has been able to verify the carbon dioxide-capture process test, is also introduced. Finally, the paper introduces a methanation demonstration plant that produces methane by carbon dioxide in flue gas and hydrogen on a commercial scale.
