A new study has found that road vent technology is the most effective solution for purifying dirty air in the UK.
Led by Professor Paul Lewis from Swansea University, the study simulated various strategies to reduce toxic nitrogen dioxide and determined that Pollution Solution's Roadvent technology is the best method to lower nitrogen dioxide (NO2) concentrations below UK regulatory standards.
The Roadvent technology works by actively capturing vehicle exhaust emissions as well as ultrafine particles generated from tire and brake wear. It is carefully installed alongside the road to capture, filter, and release clean air directly underneath the traffic. It has been independently and scientifically validated to reduce human exposure to road air pollution by 91%.
The study found that diverting heavy goods vehicles (HGVs) and buses away from the area could reduce emissions to 31 µg/m3 but may lead to increased emissions in other areas. It is anticipated that the "no-idling" initiatives alone may not be sufficient to meet regulatory requirements.
Professor Paul Lewis, the author of the study and honorary professor at Swansea University Medical School, said, "This study will be of great interest to policymakers. The government has been collecting pollution data in many areas across the country, which can inform strategic decisions on where to deploy new solutions like Roadvent. This study provides insights that can be replicated on a broader scale."
Thomas Delgado, CEO of Pollution Solution, stated, "Roadvent represents a paradigm shift in our ability to address air pollution by providing vital infrastructure that protects human life. This study demonstrates the effectiveness of our technology in tackling one of the most pressing challenges of our time, safeguarding our health and economy from the burden of air pollution."
