However, there are a range of other terms used in the sector to describe different types of incineration and [[Energy from Waste]], the kiln/furnace used, and the [[subsidy]] that may apply to them, and these are captured in the table below: | However, there are a range of other terms used in the sector to describe different types of incineration and [[Energy from Waste]], the kiln/furnace used, and the [[subsidy]] that may apply to them, and these are captured in the table below: | ||

The residual [[Incinerator Bottom Ash]] or [[IBA]] left after the combustion process is generally around 20% of the input tonnage by weight for a [[Residual Waste EFW]] plant, but will vary in quantity and chemical composition depending on the composition of the waste feedstock. This often contains minerals and metals along with non-combustible ash, which is increasingly being recycled into [[Secondary Aggregates]], with some being used for the building of roads once processed (after processing [[IBA]] is termed [[IBBA]])<ref name='ref3'>WRAP, 2019.

This gas cleaning results in a residual [[Flue Ash]] which is around 3% of the overall input to the plant by weight depending on the level of gas cleaning required. [[Fly Ash]] and [[Air Pollution Control]] (APC) residues are often combined. [[APC]] residues contain ash, carbon and lime in varying quantities and is considered a [[Hazardous Waste]] to be disposed of in a [[Hazardous Landfill]], or sometimes to be further processed through washing or stabilisation in order to make it a non-hazardous waste and allow it to be disposed of in a [[Non-hazardous Landfill]]<ref name='ref3' />. | ||

The [[Industrial Emissions Directive]] provides the regulatory framework across the EU and requires such installations to hold a [[Environmental Permit|Permit]] based on the use of [[Best Available Technique]] ([[BAT]]). | ||
On the 3rd December 2019 new EU standards were published for waste incineration <ref name="Inc" /> for new emissions, monitoring and efficiency standards. The new specifications stem from a review of [[Best Available Technique]] ([[BAT]]) Reference Document ([[BAT|BREF]]) for Waste Incineration. | On the 3rd December 2019 new EU standards were published for waste incineration <ref name="Inc" /> for new emissions, monitoring and efficiency standards.
