The optimal process conditions for enhanced aging are: a temperature of 60°C, a moisture content of 15-20%, gas composition of 4-8% CO 2 and 18-20% O 2, a gas flow rate of 0.5 m 3 /tonne/hour, and a maximum residence time of 4 weeks. The required residence time depends on the initial quality of the bottom ash.
