Understanding emissions

The incineration process that takes place at an energy from waste facility produces gas emissions and solid residues.

Emissions are subject to a strict cleaning process to ensure environmental standards set out in the Waste Licence are achieved.

More information about these emissions, including how they are formed and how they are controlled can be found in the pages in this section.

The latest emission values, can be found on the emissions monitoring page.

What about dioxins?

Dioxin is a generic term used to describe over 100 compounds. Almost all of these are harmless to humans. Dioxins are produced by combustion when carbon particles are in the 300 - 450°C temperature reaction zone, such as in garden bonfires.

The formation of dioxins is limited by minimizing the residence time of any carbon particles in the critical formation temperature zone. The facility has been designed to operate in a way that stops the formation of these substances. At over 850°C no dioxins can be formed. The facility keeps the gas stream above 850°C for over 2 seconds.

The Isle of Man facility has a specialised continually sampling meter for dioxin, which extracts any dioxins in a specially prepared cartridge. This cartridge is then sent away monthly to an UKAS accredited laboratory for analysis.
