Substitute building materials

IBAA (Incinerator Bottom Ash Aggregate) is made by processing incinerator bottom ash (IBA), which is generated in thermal treatment plants during the incineration of municipal waste (household and similar commercial waste).  
Municipal waste is incinerated at temperatures between 900 °C and 1.300 °C. According to the current state of the art, around 280 kg of bottom ash is produced in the incineration chamber per tonne of municipal waste. The bottom ash is produced from the incinerated bottom ash cooled with water through targeted processing and storage. The IBA is processed in such a way that it has consistent properties. Batches of IBA with an increased proportion of unburnt material and insufficient burnout are generally excluded from processing. Depending on the area of application, IBA can be processed into different delivery grain sizes.
