Cat’s-eye-style pollution filter under development
A new system to filter toxic pollutants from air on the roads as close to the source of traffic fumes as possible is under development in Hertfordshire.
Air pollution is a major public health hazard, with one study by the Royal Colleges of Physicians and of Paediatrics and Child Health linking it to 40,000 premature deaths per year in the UK alone along with serious ailments such as heart disease, diabetes and cancer. Approximately 5% of all worldwide deaths are caused by air pollution.
However, Hertfordshire-based Pollution Solution is developing a system that sucks polluted air from the roads before it can spread any further using cat’s-eye-style points including fans and sending it to filtration units at the side of the road to be rendered safe. The system would be powered primarily with solar power.
The company’s website states that “The air that leaves the roadside unit is cleaned to a rate of 99%, removing particulate matter (PM1-PM10) along with a range of harmful gases including nitrogen oxide (NOx), carbon monoxide (CO), hydrocarbons (HC) and ozone (O3).”
Testing on private land has already been carried out to explore real-world feasibility and Pollution Solution has confirmed that the system “is ready to be subjected to final approval testing prior to installation in the public domain”. Places such as junctions, crossings and school drop-off points where high-pollution engine idling is most common have been suggested as potential test sites.
