Future design: What 'living' clothes can do to absorb carbon emissions -

Written by Matthew Ponsford, CNN

Canadian-Iranian designer Roya Aghighi desires you to think about that your shirt is alive.

Far from dreaming up a horror film script, Aghighi hopes we can develop a extra intimate relationship with vogue — by treating clothes as dwelling beings that want our assist to survive.

“You’re not going to throw your clothes in the corner of your closet or into the washing machine,” she stated over the telephone from Vancouver. “It’s immediately going to shift the way you think about your clothing.”

Aghighi’s thought experiment is not as far-fetched because it may appear.

Working with a bunch of scientists on the University of British Columbia (UBC), she has invented a dwelling, biodegradable cloth named Biogarmentry. Made from algae, the biofabricated textile photosynthesizes, which purifies the air round it.

UBC claims it is the primary dwelling and photosynthesizing textile, and has long-established the fabric right into a sheer, cloak-like garment. While prototypes like these are nonetheless within the early levels of analysis and design, and much from mass manufacturing, they problem the style business to reimagine methods it can cut back its colossal carbon footprint by various materials.

Fashion fail

Fashion is without doubt one of the world’s most polluting industries. It’s accountable for extra carbon emissions than worldwide flights and delivery mixed, amounting to 10% of all greenhouse gasses emitted globally, in accordance to figures from the United Nations Environment Programme (UNEP).

US shoppers are shopping for extra clothes than ever, carrying every merchandise fewer instances and sending nearly 70% of the clothes and footwear produced annually to landfill, in accordance to the US Environmental Protection Agency.

Changing our relationship with clothes, from one in every of neglectful fast-fashion consumption to an empathetic connection, is one in every of Aghighi’s most important drivers.

While her progressive garment is now solely on the proof-of-concept stage, patrons might in the future be instructed to stretch the material out in entrance of a window earlier than placing it on. With daylight and a twig of water, its single-cell chlamydomonas reinhardtii algae come to life.

Aghighi predicts consumption habits will take a very long time to change. “It is going to be a slow shift,” she stated. “But I hope that it’s gonna be a long-lasting one.”

Carbon-negative vogue

The crops historically used to make clothes, from cotton to hemp, absorb carbon as they develop. So, too, do a rising variety of manufactured supplies derived from crops, like Rayon, which is produced from wooden pulp that’s chemically transformed into purified cellulose.

But end-to-end, most pure supplies are nonetheless carbon emitters, says New York-based designer Charlotte McCurdy, a fellow at Rhode Island School of Design.

Take a single T-shirt manufactured from cotton, the world’s mostly used pure fiber, for example.

The estimated footprint of a cotton shirt over its lifetime is 15 kilograms (33 kilos) of carbon dioxide, with most of that emitted in the course of the energy-intensive manufacturing and dyeing processes.

In current years, environmental startups have proposed plenty of various pure fibers, from beechwood made into cashmere-like beachwear to cactus leather-based. Many of those have the potential to sequester carbon however none have been proven to obtain net-zero emissions over the lifecycle of a garment, particularly when washing and drying clothes considerably add to their general footprint. Instead, so-called “carbon-negative” manufacturers resort to carbon offsetting — planting bushes — to deliver their internet emissions down.

In her analysis, McCurdy has, like Aghighi, seemed to potentialities of algae, and its capability to lure carbon. She has created a carbon-negative raincoat produced from a plastic-like materials manufactured from marine algae and different biodegradable elements.

Like cotton or hemp, algae sequesters carbon because it grows, photosynthesizing to seize carbon dioxide from the air. Microalgae can seize ten instances as a lot daylight as terrestrial crops, and it grows quick — with some species ready to double their biomass inside a number of hours. It can be transformed into powder, earlier than being spun right into a fiber.

“The point is not to make a plastic out of algae,” McCurdy stated at a speak organized by New York City’s New Museum. “The point is to sequester carbon, and it matters how we do that and how those systems scale.”

The message

Sustainably scaling up algae-based cloth manufacturing will probably be important if these clothes are to develop into the idea for carbon-negative vogue.

Algal biotechnology is an enormous enterprise. Beyond the world of vogue, it is seen instead for polyurethane plastics — the world’s commonest plastic, which is utilized in all the things from luggage to outside furnishings — in addition to in materials.

Stephen Mayfield, a organic sciences professor at UC San Diego who has made a biodegradable flip flop, says algae-based supplies are, at the moment, the place electrical automobile applied sciences had been a decade in the past.

“It was clear they were the future of transportation and it was just a matter of time. Algae is poised in the same way,” he stated. “The technology is now ready for prime time.”

Biotech start-ups from the US to China are racing to scale up these materials, from ideas to mass-production processes that can compete with cotton or artificial supplies on worth. McCurdy sees this as a promising route ahead and desires to present that algae-based clothes can be not solely environmentally sound however aesthetically daring and futuristic.

The raincoat produced by McCurdy’s “After Ancient Sunlight” challenge was featured in “Nature,” the Cooper Hewitt museum’s 2019 Design Triennial, final yr. She was inquisitive about the truth that daylight is accountable for each the photosynthetic vitality produced by algae and the fossil gas vitality, like oil or coal, that traces its origins to prehistoric crops and algae.

“Part of what this project is speaking to, is that we used to be in a society that fulfilled all of its needs through the energy of the sun,” she stated. “And then we got dependent on this stored, ancient super-energy-dense sunlight.” (The majority of plastics are produced from fossil fuels, or shops of carbon created by “ancient sunlight,” because the Cooper Hewitt’s exhibition famous.)

“And we can get back to building our society from sunlight. So there’s some sort of poetic tension between rain and sunlight.”

In the lab, Aghighi’s cloth develops totally different patterns — natural shapes, spots and bands — because the algae develop, the designer stated. When the ensuing clothes are commercially accessible, she imagines folks tending to their very own natural cloak, spraying their organism as they commute to work and inspiring their algae to purify the air and develop distinctive, particular person motifs.

“I’m not saying that your clothes should be your pets,” she stated. “I mean, to be honest, secretly, I do say that.”
