Tyre maker ENSO honoured for tackling electric car pollution
By AFP | 21 September 2023LONDON: A British company selected as a finalist for Prince William's Earthshot Prize now promises more durable tyres that increase vehicle range and decrease the emission of toxic chemicals.
"We have here a very harmful and hidden pollution," Gunnlaugur Erlendsson, founder and CEO of ENSO, which caters specifically to electric vehicles, said. "We're exposed to it whenever we breathe."
Because of decades of regulations that brought about improvements to internal combustion engines, tyre and brake wear are today responsible for significantly more small particle pollution than vehicle exhausts, studies show.
Tyre wear particles are also microplastics, with emerging evidence linking them to a range of impacts on heart and lung health, as well as cancers, in addition to widespread environmental harm.
For example, as much as 28 percent of the microplastics that reach the ocean comes from tyre wear.
Some research suggests that electric cars might be worse offenders than gasoline and diesel powered vehicles on this front.
A study carried out by the research company Emissions Analytics this year found that the Tesla Model Y was responsible for 26 percent more emissions than the similar-sized hybrid Kia Niro. The report's authors said the electric car's heavier weight and harder acceleration was to blame.
Erlendsson disagrees with the idea that electric cars are uniquely problematic — rather, the tyre pollution problem has grown as vehicles become heavier, with the US market in particular trending towards large SUVs.
By using higher-grade raw materials combined with better engineering, ENSO has been able to improve its tyres in a market that hasn't prioritised durability.
During real-world trials organised by Transport for London, the company's tyres were shown to reduce particulate emissions by 35 percent and increase driving range by 10 percent.
"The energy saving we deliver is a direct carbon reduction because we still don't live in a world where electricity comes only from non-carbon sources," said Erlendsson.
By contrast, the wider industry is focused on cost-saving, making tyres that don't last as long and need to be replaced faster, in order to boost sales. Researchers in the field of tyre pollution are demanding stricter regulation, a call Erlendsson agrees with.
All that said, there are limits, he stressed. "We won't make tyres last forever, but we can severely reduce the pollution that comes off them," he said.
"But of course, if people don't want to be generating tire pollution, they shouldn't be driving."
ENSO was among 15 Earthshot Finalists honoured on Tuesday on the sidelines of the United Nations General Assembly in New York.
They are now in the running to receive one of five £1 million prizes (RM5.8mil) awarded at a ceremony in Singapore later this year.
