LONDON • The newest wearable technology favoured by former Apple design chief Jony Ive is a mask for cows that captures planet-warming methane gas.
The bovine mask designer, Zelp, is one of four winners of the Terra Carta Design Lab award announced on Tuesday.
Mr Ive and Prince Charles served on the grand jury for the inaugural contest, which is associated with the Royal College of Art in Britain and is part of the Prince of Wales' Sustainable Markets Initiative.
The award was created to showcase innovative solutions to the climate crisis.
Each winner receives £50,000 (S$87,000) and mentoring from Mr Ive, who serves as the chancellor of the Royal College of Art, and other members of the Sustainable Markets Initiative.
Cow burps are a significant source of methane, which is a far more powerful greenhouse gas than carbon dioxide (CO2).
Most solutions have focused on developing feed additives to cut emissions.
The mask developed by Zelp, which stands for Zero Emissions Livestock Project, captures methane with each burp.
A catalyst oxidises the gas and releases it into the atmosphere as CO2 and water vapour.
The company estimates the device can reduce methane emissions from cow belches by more than 50 per cent.
"We think it can play a huge role," said Mr Francisco Norris, Zelp's co-founder and chief executive. "The additional upside for the farmer working with us is that they can tap into the data that we collect on the animals' health."
Agriculture giant Cargill has tested the masks and Mr Norris said he expects a commercial launch of the product next year after the design is finalised.
The British start-up plans to offer the mask initially in Europe as a service where subscribers pay an annual fee per cow.
Another Terra Carta award winner has designed technology to capture microplastics generated by vehicle tyres.
A 2019 study found tyres to be the biggest source of microplastic pollution in California's coastal waters.
The device created by The Tyre Collective sits behind a vehicle's wheels and contains electrostatic plates that collect charged microplastic particles shed by the tyres. It absorbed 60 per cent of particles in laboratory tests.
Mr Hanson Cheng, a co-founder of The Tyre Collective, said the British company attached the device to a sport utility vehicle and has completed a seven-week, 3,000km road test in London.
"On the road, we're not at 60 per cent just yet," said Mr Cheng, but he noted that the tests showed the device also collected particles from other vehicles' tyres and what appeared to be microplastics from brake pads.
"When we talk about vehicle emissions it's just focused on the exhaust, but tyres are the second-largest source of microplastic pollution and are a source of air pollution-particulate matter that has an impact on human health," said Mr Cheng.
He said the company, which is looking for partners in the United States, is also exploring how to recycle the collected microplastics into new products and will initially target urban delivery fleets.
Another Terra Carta winner is Aerseeds, which has developed a seed pod made from food waste that is designed to be dispersed by the wind for reforestation and other ecological restoration efforts.
The fourth winner is Amphitex, which has created a chemical-free, 100 per cent-recyclable textile for waterproof outdoor apparel.
