Tire Pollution Will Get Worse With New Evs The Tire Collective

Electric cars may have zero emissions, but they still emit harmful waste through their tires. Actually, all cars shed bits of spent rubber when they drive on the roads, as the rubber and other toxic compounds in the tires are ground down. Since EVs are heavier and accelerate faster than ICE-powered cars, they chew up tires faster and expel more of these dirty particles or tire emissions. But a London start-up called Tire Collective is trying to clean up rubber-burning EVs — and ICE-powered cars, too — with a device called a “box” that bolts behind the wheel. It’s basically a tire emissions cover. The tailpipes have catalytic converters that collect the waste, and now the tires have this new (unnamed) device, according to Bloomberg. The box captures tire particles using electrostatic plates. As the car tire rolls, the ejected particles are “charged by friction on the road” and the Tire Collective box pulls them in. Photo: The Tire Collective The device can capture up to 60 percent of tire emissions in the lab, but only about 20 percent in real-world conditions. The startup is currently testing prototypes on a few delivery vans in London to increase the particle collection rate. G/O Media may receive a commission Now that EVs are hitting the market, Tire Collective thinks it’s the best time to perfect their design. Because of their larger size, higher weight and greater torque, EVs produce 20 percent more tire emissions than comparable ICE-powered cars. A gas-burning car emits 73 milligrams per kilometer from all four tires. a comparable EV emits around 88 milligrams per kilometer. Damn you, metric system! Photo: The Tire Collective In any case, we’re talking particulate matter per mile, but when you consider how many vehicles are on the road and the distance each one will travel, tire emissions add up. Research shows that tires are the second leading source of microplastics in the ocean. And because scientists are just beginning to study and record tire emissions, we don’t fully know how harmful these pollutants are. You can read about the dangers of petrochemicals in tires at Bloomberg, but a study cited in the report found a new byproduct of tire emissions called 6PPD-quinone, which has been mass killing salmon in Washington state. When exposed to the sun and air, 6PPD turns into a chemical called 6PPD-quinone, which proves highly toxic to coho salmon – causing them to circle, gasp at the surface, and then die within hours . Dealerships in the US are trying to add tires containing the chemical preservative 6PPD to their list of hazardous products to encourage tire manufacturers to find safe substitutes. But the study of tire emissions is relatively new. The whole thing has been overshadowed — understandably — by exhaust emissions and CO2 pollution. Tire Collective plans to install its particulate collection device in commercial and municipal fleets. The startup hopes it can convince EV manufacturers to equip new cars with similar devices at the factory. The devices would then be emptied at service intervals and the particles could be used to make new tires or other rubber products. This is much better than ending up in the ocean.
