[WORLDKINGS - Ideastime] Daily Highlights 16 June, 2022 – H&M-backed project pilots CO2-capturing apron at Stockholm restaurant

(WorldKings.org) In a pilot of a technique developed by H&M-backed researchers, the crew of a Stockholm restaurant wear cotton aprons that capture greenhouse gases from the air, as the fashion industry tries to reduce its climate impact.

The textile industry has a large carbon footprint, something the fashion giant is under increasing pressure to address as shoppers become more aware of the environmental impact of clothing and as global temperatures rise.

The Hong Kong Research Institute of Textiles and Apparel (HKRITA) has developed an amine-containing solution with which to treat cotton – fiber, yarn or fabric – that causes the cotton to attract and hold carbon dioxide gas, followed by Stabilizes and stores it. on the surface of the cloth.

 

 

HKRITA CEO Edwin Keh said in an interview that his team is inspired by techniques used in the chimneys of coal-fired power plants to limit emissions.

“Many power plants have to clear as much carbon dioxide from the air as they can before the exhaust is released,” Keh told Reuters. “We thought ‘why don’t we try to replicate that chemical process on cotton fiber’.

Keh said that a T-shirt is capable of absorbing about a third of what is absorbed by a tree per day. “The (capturing) potential isn’t huge, but it’s cheap enough and easy enough to produce, and we think there’s a lot of potential applications.”

Keh said the apron in the pilot was manufactured at an H&M supplier in Indonesia, using existing equipment from the factory. “It’s a fairly simple chemical process.”

In pilot the aprons are used after heating to 30–40 °C, the temperature at which they release CO2 – the gas in a greenhouse where plants take in.

 

 

The H&M Foundation said the innovation could potentially be a game changer in the reduction of global CO2 emissions.

Although projects to develop CO2 absorbing fabrics are in the early stages, their potential contribution to reducing the environmental impact of the textile industry remains to be seen.

Keh said the institute will now further develop its technology, and seek to find other uses for it, as well as other ways to use or dispose of the captured CO2.

HKRITA, which is partly financed by the philanthropic arm of Swedish fashion retailer H&M, has developed a number of innovations aimed at making fashion more sustainable. One that has reached industrial-scale use is a technique for separating cotton and polyester fibers into blend-fabrics.
