A student-built electric concept aims to reduce road pollution by collecting microscopic particles released by tires and brakes.
A team of students from Eindhoven University of Technology in the Netherlands has developed Ventra, a concept electric car designed to tackle a less obvious source of road pollution. Although EVs produce no tailpipe emissions, their tires and braking components still wear down during use, releasing fine particles into the environment. Ventra aims to capture some of that pollution before it spreads.
The system gives airborne particles an electrical charge as the vehicle moves, allowing them to collect in a dedicated container. After a trip, the container can be removed and its contents sent for recycling. According to the student team’s estimates, the system can capture up to 42% of these particles, depending on driving speed.
Ventra also takes a lightweight approach to reducing its environmental impact. A lower vehicle weight puts less pressure on the road surface and can help reduce tire wear. The car’s chassis consists of several panels made from a thermoplastic composite reinforced with carbon fiber for added stiffness.
The result weighs just 1,742 pounds. Ventra has a top speed of around 55 mph and a claimed range of approximately 180 miles on a full charge.
The concept also uses onboard electronics to monitor several driving parameters, including driver behavior. The system can offer suggestions for smoother driving, which may help reduce tire and brake wear and limit the amount of particulate pollution generated on the road.
Ventra remains a concept rather than a production-ready vehicle, but its approach highlights an emerging challenge for electric cars: eliminating tailpipe emissions does not eliminate every source of pollution. By combining particle collection with lightweight construction and driving feedback, the student project explores ways to make future EVs cleaner beyond the exhaust pipe.
