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 as [[Secondary Aggregate]] into applications such as aggregate replacement for sub-base road construction, bulk fill, concrete block manufacture or concrete grouting<ref name="foo" />. When recycled back to an aggregate it is known as '''[[Incinerator Bottom Ash Aggregate]]''' ([[IBAA]]).The use of [[IBAA]] in construction has specific controls that need to be applied<ref>https://www.gov.uk/government/publications/using-unbound-incinerator-bottom-ash-aggregate-ibaa-in-construction-activities-rps-247</ref>.

The graph below displays the incinerator bottom ash produced as a percentage of the total [[residual waste]] feedstock being processed by UK [[Energy from Waste]] facilities, and how this has changed over recent years.

The graph below displays the incinerator bottom ash produced as a percentage of the total [[residual waste]] feedstock being processed by UK [[Energy from Waste]] facilities, and how this has changed over recent years. Since 2019 the figure has dropped to around 19.2% of input tonnage.
