Calcining will release CO2 from the lime plus CO2 from the fuel to heat it. Only the former will be reabsorbed over time.
And if the timescales are long enough the absorbtion still wouldn't bring you to net-zero because during the time the CO2 in the atmosphere it participated in positive feedback loops.
