Emissions performance of the Dublin Waste to Energy Ltd. facility is measured and recorded by a continuous emissions monitoring system (CEMS). Emissions data is also collected during source (stack) tests.
Continuous emissions data on this web page is collected by the facility’s Distributed Control System (DCS) and automatically posted as close to real time as possible for information purposes. Data has not undergone final verification or complete quality control and quality assurance procedure; therefore, this data should not be used in published documents. Final verification and quality control procedures are undertaken on a regular basis and are stored on the DCS master log for regulatory purposes.
The tabular representation below shows the 1/2hourly averages from the continuous monitoring for total dust, gaseous and vaporous organic substances expressed as Total Organic Carbon, Hydrogen Chloride, Carbon Monoxide, Sulphur Dioxide and Oxides of Nitrogen emitted from each stack A2-1 and A2-2.. The measured values and emission limit values are described in mg/Nm3. These values have been standardized to the following conditions in accordance with the license: temperature of 273 K, pressure of 101.3 kPa, dry gas and 11% oxygen.
Note: Waste is not combusted at temperatures below 850°C. Once the furnace reaches 850°C using auxiliary fuel, it is only then that waste is introduced for combustion.

The tabular representation below shows the daily averages from the continuous monitoring for total dust, gaseous and vaporous organic substances expressed as Total Organic Carbon, Hydrogen Chloride, Carbon Monoxide, Sulphur Dioxide and Oxides of Nitrogen emitted from each stack A2-1 and A2-2 and is displayed one week behind. The measured values and emission limit values will be described in mg/Nm3. These values have been standardized to the following conditions in accordance with the license: temperature of 273 K, pressure of 101.3 kPa, dry gas and 11% oxygen.

An independent third party testing company performs periodic stack emissions testing for both combustion lines at the Dublin Waste to Energy facility. The purpose of the testing is to evaluate if emissions comply with the emission limit values (ELV) as set out in the facility’s licence that was granted by the Environmental Protection Agency under the Industrial Emissions Directive (IED). Results from the testing demonstrate that the emissions are significantly below the limits required. A summary table of the results is outlined below.
