Provided is a carbon dioxide utilizing system in which, while utilizing carbon dioxide in exhaust gas, the amount of waste of fresh concrete sludge typically discarded as a waste can be reduced, and calcium carbonate can be efficiently reutilized. The carbon dioxide utilizing system includes: a flue through which exhaust gas containing carbon dioxide passes; a spray nozzle that supplies fresh concrete sludge water to the flue; and a dust collection device that recovers a reaction product containing calcium carbonate produced by reaction of the carbon dioxide in the exhaust gas and the fresh concrete sludge water.
