Abstract: The disclosure provides a method and a system for processing concrete granulate for subsequent recycling of the concrete granulate. In the method, a container of the system is filled with concrete granulate, said container being gas-tight at least in some regions. Subsequently, gas comprising CO2 is fed, continuously or noncontinously, according to a level of CO2 absorption by the concrete granulate in the container, said level being determined by means of at least one sensor. After a predefined CO2 saturation of the concrete granulate has been detected, the concrete granulate, which have been enriched with CO2, are removed.
