[[Healthcare Waste|Healthcare wastes]] are loaded mechanically direct from the wheeled bins used to deliver the [[Clinical Waste|waste]], into the hopper which provides the opportunity to visually inspect the [[Clinical Waste|waste]] before it is tipped into the [[Incineration|incinerator]] charging hopper. Once inspection is complete, the [[clinical Waste|waste]] is charged into the [[Incineration|incinerator]] where the [[combustion|combustion]] process commences. The [[Clinical Waste|waste]] is burnt at a minimum temperature of 850°C,where it burns out to produce an ash. The residues are then dropped into an ash quench pit at the end of the process before being transferred into a skip.

The [[flue gases]] from the [[Incineration]] process then pass through a secondary chamber, or afterburner, where any gaseous products of [[Combustion]] are burned out under oxygen rich conditions. This stage is designed to destroy any [[Wikipedia:Carbon monoxide|Carbon Monoxide]], [[Wikipedia:Volatile organic compound|Volatile Organic Compounds]], and [[Wikipedia:Dioxins and dioxin-like compounds|dioxins]] and [[Wikipedia:Furan|furans]] produced by the [[Combustion]] process.

The [[flue gases]] are then cooled by passing through a waste-heat boiler and economiser, before passing into the final, abatement section of the process. Powdered [[Lime (material)|lime]] (Calcium Hydroxide) and powdered [[wikipedia:Activated carbon|activated carbon]] are added to the flue gases entering the abatement process to remove acid gases, heavy metals and residual [[Wikipedia:Dioxin|dioxins]] and [[Wikipedia:Furan|furans]] before discharge to atmosphere from the stack. The flue gases being discharged from the stack are continuously monitored for [[wikipedia:Hydrogen chloride|Hydrogen Chloride]], [[wikipedia:Sulfur dioxide|Sulphur Dioxide]], [[Wikipedia:Carbon monoxide|Carbon Monoxide]], [[Wikipedia:Nitrogen oxide|Oxides of Nitrogen]], particulate matter (dust), [[Wikipedia:Volatile organic compound|Volatile Organic Compounds]], [[Wikipedia:Oxygen|oxygen]], [[Wikipedia:Ammonia|Ammonia]] and [[Wikipedia:Nitrous oxide|nitrous oxide]].

The [[Incineration|incineration]] process produces two residues; [[bottom ash]] and spent lime.
