Roadside exhaust vent touted as anti-pollution technology that could avoid motor vehicle ban

Suction technology for roadside pollution could be a “viable alternative to ban” [motor] traffic,” says a public health expert. Frank Kelly, the Battcock Chair in Community Health and Policy at Imperial College London, responded to the (re)launch of Roadvent by British company Pollution Solution.

Eight years in development, the technology has been independently tested to reduce exposure to roadside pollutants pumped out by car traffic by 91%.

The roadside ventilation system could be installed outside schools and along road sections that suffer from the worst pollution from traffic, said innovator Thomas Delgado, founder and CEO of Pollution Solution.

Delgado is a serial entrepreneur. The car enthusiast started the online car sales website We buy cars today in 2010 as twenty years oldleft the company nine years later.

An earlier version of Roadvent was: launched in 2018

Roadvent “allows” [local] authorities to provide clean, safe and legal air quality to the public as they transition to 100 percent electric motorized vehicles, while fossil fuel vehicles remain on the road,” a statement said. Delgado’s LinkedIn profile

Dead

Road pollution is a major cause of death. Last year, an English coroner ruled that nine-year-old asthmatic Ella Adoo-Kissi-Debrah’s death was caused by exposure to traffic pollution.

Public Health England has warned that if action is not taken to control pollution levels, the cost of the NHS and social care could exceed $25 billion by 2035. According to PHE, there could be around 2.5 million new cases of coronary artery disease, stroke, lung cancer, childhood asthma, chronic obstructive pulmonary disease, diabetes, low birth weight and dementia by 2035 if current air pollution levels persist.

Cambustion UK has tested Roadvent at UTAC Millbrook Proving Ground, Bedford, UK demonstrating its effectiveness at capturing polluted air directly from the roadway.

“While progress has been made in reducing vehicle emissions in urban locations, there are still hot spots where traffic is at a standstill or moving slowly,” said Professor Kelly.

“Roadvent offers a promising viable alternative to traffic bans, as the system soaks up road surface pollution before it can spread to nearby places. [footways],” he added.

Smoke and particulate matter from vehicles are drawn into the system and pumped through pipes to a filter unit that captures most of the pollutants.

The system will be offered in 10-metre modules with pricing depending on location and the type of filtration required, a Delgado-appointed PR firm said.

According to this PR firm, early tests of the system showed a significant reduction in nitrogen dioxide (NO2) concentrations, one of the main pollutants emitted by diesel vehicles.

Hirra Khan Adeogun of London-based climate charity Possible, who claimed it is “overdeveloped technology”, said Roadvent “will not solve our toxic air problem.”

She added that “vehicle traffic is a huge source of CO2 emissions in the UK and this technology will do nothing to address the impact of traffic on the climate crisis. We already have the most effective tools to reduce all types of pollution from private cars.”

These tools, she says, include road user charges, pedestrians, bicycle infrastructure, public transportation, and parking and traffic mitigation measures.

“All of these,” she added, “come with the added benefits of safer streets.”
