The [[High Temperature and Clinical Waste Incineration|incinerator]] has a design capacity of 650kg/h with a typical operating capacity of ~510kg/h. The [[High Temperature and Clinical Waste Incineration|incinerator]] is fitted with air pollution control comprising of lime injection (to control emissions of [[Wikipedia:Sulfur dioxide|sulphur dioxide]] and [[Wikipedia:Hydrogen chloride|hydrogen chloride]]) and [[Wikipedia:Activated carbon|activated carbon]] (to control emissions of [[Wikipedia:Heavy metals|heavy metals]] and [[Wikipedia:Dioxins and dioxin-like compounds|dioxins]]). There is also a high efficiency bag filtration system for the removal of [[Wikipedia:Particulates|particulate matter]]. There is a secondary [[Combustion|combustion]] chamber that provides the required residence time of more than 2 seconds at a temperature of at least 850°C and 1000°C for cytotoxic wastes. Natural gas is used to support the [[Combustion|combustion]] and to maintain the secondary temperatures. | The [[High Temperature and Clinical Waste Incineration|incinerator]] has a design capacity of 650kg/h with a typical operating capacity of ~510kg/h.

Emissions to air are discharged via a 70-metre stack. There is an energy recovery system, and the [[high Temperature and Clinical Waste Incineration|incinerator]] supplies hot water to the adjacent hospital. Solid wastes produced are primary bottom ash and residues from the air pollution control system. | Emissions to air are discharged via a 70-metre [[wikipedia:Chimney|stack]].
