M5 East: a review of emission treatment technologies, systems and applications

Summary

The RTA commissioned Child & Associates in 2004 to undertake a review of international developments in emission treatment systems in road tunnel applications.
This report is the fifth review of international developments in the technology as required under the conditions of approval for the M5 East.
The report concludes that:
  • Progress has been made in the field of emission treatment technology and that viable technologies are now available to remove ‘suspended particles, nitrogen dioxide, some portion of other oxides of nitrogen and hydrocarbon vapours’ from road tunnel exhaust air.
  • A potential basis for the cost-effective use of emission treatment technology in road tunnels has been identified.
  • The use of emission treatment technology in road tunnels would require detailed consideration of ventilation and air quality issues specific to each individual tunnel.
