How a Student-Built Electric Car Cleans Air Pollution as It Drives

TU Eindhoven students built VENTRA, an electric car using electrostatics to capture tire and brake dust, remarkably recycling the collected pollution into the vehicle’s interior dashboard coating.

Rethinking the Environmental Cost of Electric Mobility

The student team TU/ecomotive from Eindhoven University of Technology (TU Eindhoven) in the Netherlands has officially unveiled VENTRA, a novel concept car designed to address the growing issue of non-exhaust vehicle emissions [1][5]. Developed over the course of a single year by a multidisciplinary cohort of 40 students representing 23 nationalities and eight academic fields [3][4], the electric vehicle was showcased to the public at the Zandvoort circuit over the weekend of September 26–27, 2026 [6]. While battery electric vehicles eliminate tailpipe carbon emissions, they continue to generate substantial particulate matter (PM) through tire, brake, and road wear—a problem often intensified by the heavy weight and rapid torque of electric drivetrains [1][2].

Electrostatic Capture and Circular Materials

To mitigate these emissions and the associated health risks—which include cardiovascular disease, strokes, chronic obstructive pulmonary disease (COPD), and lung cancer [1]—VENTRA is designed around its proprietary “TRACE” system [8]. Rather than using physical filters that require replacement, the car utilizes an electrostatic capture system that applies an electrical charge to attract airborne dust directly at the tires, pulling the particles onto a grounded collection surface [1][2]. Simulations of the technology indicate a particulate capture efficiency of 42% at lower urban speeds and 24% when driving between 50 and 80 km/h [1]. Team manager Tim Spencer emphasized the importance of this approach, noting that “no exhaust emissions does not necessarily mean no emissions” [1].

Modular Design and Weight Reduction

In a unique circular design loop, the captured particulate matter is safely recycled into enamel coatings, which the student team used to coat VENTRA’s interior dashboard [3]. The vehicle’s body, designed by team members Yves Oude Elberink and Teo Zink, was built modularly around the TRACE system, leaving ample physical clearance in the fenders, bumpers, and side panels for continued system optimization [8]. To reduce the physical forces that cause tire wear in the first place, the car features a lightweight chassis composed of carbon-fiber-reinforced thermoplastic sandwich panels, saving nearly 100 kg in overall vehicle mass [1][2]. The team also collaborated with Van Wees to manufacture lightweight seats using the same sandwich panels, with each seat weighing just 4.6 kg [7]. For a two-seat configuration, this limits the total seating weight to a mere 9.2 kg [7].

Regulatory Alignment and the Path Forward

VENTRA’s debut arrives at a critical regulatory juncture, as the European Euro 7 emissions regulations are scheduled to take effect in November 2026 [1]. These updated standards will introduce the first-ever legal limits on non-exhaust emissions stemming from brake and tire wear [1][2]. To help drivers actively minimize wear, VENTRA includes a “Clean Drive” system that monitors acceleration and braking in real time, offering dashboard feedback to encourage smoother driving habits [1][2]. Built with the support of partners like Delta-Q Technologies, which supplied its XV3300 charger [4], the prototype demonstrates that full-vehicle sustainability can be achieved through cost-effective engineering choices, such as 3D-printed components, flat side windows, and recycled monomaterial offcuts [7][8].
