Incinerator Bottom Ash: Difference between revisions

Revision as of 04:47, 8 November 2019

The ash resulting from the controlled combustion of waste, in the UK p[rimarily MSW. Not to be confused with Flue Gas APC Residues cleaning residues or boiler (tube) ash.

IBA generally represents around 20% of the input material by weight.

Following the combustion process non-combustible ash of varying particle size is produced, often containing mineral material and metals. The ash which falls to the bottom of the process is typically dry and dusty and operators will need to ensure that it is appropriately stored in covered containers to prevent emissions to air.

Currently, over half a million tonnes of IBA goes to landfill each year in England and Wales. However, as recovery processes have improved this material can now be processed and recycled back into applications such as aggregate replacement for sub-base road construction, bulk fill, concrete block manufacture or concrete grouting ^[1].
