Peterborough ERF Emissions Page
The site environmental permit for the Peterborough Energy Recovery Facility sets the limits of a range of substances which have to be measured in the stack emissions. These limits are based upon the Industrial Emissions Directive 2010.
The contents of the stack emissions listed below are measured on a minute by minute basis 24/7 by the Continuous Emissions Monitoring System (CEMS).
Additional monitoring is completed by an independently-certified external test house using an extractive technique where air samples are collected from the stack flow over a period of time and analysed by an Environment Agency approved laboratories.
Daily Average Emissions Limit:
- Dust (Particulates) 10mg/m³
- Total Organic Carbon 10mg/m³
- Hydrogen Chloride 10mg/m³
- Carbon Monoxide 50mg/m³
- Sulphur Dioxide 50mg/m³
- Oxides of Nitrogen 150mg/m³
The daily average emissions limits for Peterborough Energy Recovery Facility are the strictest in the Viridor fleet. The standard industry daily average emissions limit for Oxides of Nitrogen is 200mg/m³.
Particulate Matter is generally categorised on the basis of the size of the particles. It is made up of a wide range of materials and can arise from a variety of sources. Particulate Matter derives from both human-made and natural sources, such as sea spray, Saharan dust and volcanic eruptions. In the UK one of the biggest human-made sources is transport.
Total Organic Carbon
Total Organic Carbon is part of a group of liquids and gases often called volatile organic compounds (VOCs). Many industrial processes emit VOCs including printing, surface coating and painting, however, households and road transport also contribute a substantial fraction.
At room temperature, hydrogen chloride exists as either a colourless or slightly yellow gas. The main source of Hydrogen Chloride is old coal burning power stations.
Carbon Monoxide is formed from incomplete combustion of carbon containing fuels. The largest source is from road transport, older vehicles which do not have catalytic convertors produce significant amounts with newer cars producing very little.
UK emissions are dominated by combustion of fuels containing sulphur, such as coal and heavy oils by power stations and refineries. In some parts of the UK, notably Northern Ireland, coal for domestic use is a significant source.
Oxides of Nitrogen
All combustion processes in air produce oxides of nitrogen (NOx). Nitrogen dioxide (NO2) and nitric oxide (NO) are both oxides of nitrogen and together are referred to as NOx. Road transport is the main source, but this can also be formed in lightning storms and from natural breakdown processes in soil and water.
