In 2023, the fast-fashion giant Shein was everywhere. Crisscrossing the globe, airplanes ferried small packages of its ultra-cheap clothing from thousands of suppliers to tens of millions of customer mailboxes in 150 countries. Influencers’ “#sheinhaul” videos advertised the company’s trendy styles on social media, garnering billions of views.

At every step, data was created, collected, and analyzed. To manage all this information, the fast fashion industry has begun embracing emerging AI technologies. Shein uses proprietary machine-learning applications — essentially, pattern-identification algorithms — to measure customer preferences in real time and predict demand, which it then services with an ultra-fast supply chain.

As AI makes the business of churning out affordable, on-trend clothing faster than ever, Shein is among the brands under increasing pressure to become more sustainable, too. The company has pledged to reduce its carbon dioxide emissions by 25 percent by 2030 and achieve net-zero emissions no later than 2050.

But climate advocates and researchers say the company’s lightning-fast manufacturing practices and online-only business model are inherently emissions-heavy — and that the use of AI software to catalyze these operations could be cranking up its emissions. Those concerns were amplified by Shein’s third annual sustainability report, released late last month, which showed the company nearly doubled its carbon dioxide emissions between 2022 and 2023.

“AI enables fast fashion to become the ultra-fast fashion industry, Shein and Temu being the fore-leaders of this,” said Sage Lenier, the executive director of Sustainable and Just Future, a climate nonprofit. “They quite literally could not exist without AI.” (Temu is a rapidly rising ecommerce titan, with a marketplace of goods that rival Shein’s in variety, price, and sales.)

In the 12 years since Shein was founded, it has become known for its uniquely prolific manufacturing, which reportedly generated over $30 billion of revenue for the company in 2023. Although estimates vary, a new Shein design may take as little as 10 days to become a garment, and up to 10,000 items are added to the site each day. The company reportedly offers as many as 600,000 items for sale at any given time with an average price tag of roughly $10. (Shein declined to confirm or deny these reported numbers.) One market analysis found that 44 percent of Gen Zers in the United States buy at least one item from Shein every month.

That scale translates into massive environmental impacts. According to the company’s sustainability report, Shein emitted 16.7 million total metric tons of carbon dioxide in 2023 — more than what four coal power plants spew out in a year. The company has also come under fire for textile waste, high levels of microplastic pollution, and exploitative labor practices. According to the report, polyester — a synthetic textile known for shedding microplastics into the environment — makes up 76 percent of its total fabrics, and only 6 percent of that polyester is recycled.

And a recent investigation found that factory workers at Shein suppliers regularly work 75-hour weeks, over a year after the company pledged to improve working conditions within its supply chain. Although Shein’s sustainability report indicates that labor conditions are improving, it also shows that in third-party audits of over 3,000 suppliers and subcontractors, 71 percent received a score of C or lower on the company’s grade scale of A to E — mediocre at best.

Machine learning plays an important role in Shein’s business model. Although Peter Pernot-Day, Shein’s head of global strategy and corporate affairs, told Business Insider last August that AI was not central to its operations, he indicated otherwise during a presentation at a retail conference at the beginning of this year.

“We are using machine-learning technologies to accurately predict demand in a way that we think is cutting edge,” he said. Pernot-Day told the audience that all of Shein’s 5,400 suppliers have access to an AI software platform that gives them updates on customer preferences, and they change what they’re producing to match it in real time.

“This means we can produce very few copies of each garment,” he said. “It means we waste very little and have very little inventory waste.” On average, the company says it stocks between 100 to 200 copies of each item — a stark contrast with more conventional fast-fashion brands, which typically produce thousands of each item per season, and try to anticipate trends months in advance. Shein calls its model “on-demand,” while a technology analyst who spoke to Vox in 2021 called it “real-time” retail.

At the conference, Pernot-Day also indicated that the technology helps the company pick up on “micro trends” that customers want to wear. “We can detect that, and we can act on that in a way that I think we’ve really pioneered,” he said. A designer who filed a recent class action lawsuit in a New York District Court alleges that the company’s AI market analysis tools are used in an “industrial-scale scheme of systematic, digital copyright infringement of the work of small designers and artists,” that scrapes designs off the internet and sends them directly to factories for production.

In an emailed statement to Grist, a Shein spokesperson reiterated Peter Pernot-Day’s assertion that technology allows the company to reduce waste and increase efficiency and suggested that the company’s increased emissions in 2023 were attributable to booming business. “We do not see growth as antithetical to sustainability,” the spokesperson said.

An analysis of Shein’s sustainability report by the Business of Fashion, a trade publication, found that last year, the company’s emissions rose at almost double the rate of its revenue — making Shein the highest-emitting company in the fashion industry. By comparison, Zara’s emissions rose half as much as its revenue. For other industry titans, such as H&M and Nike, sales grew while emissions fell from the year before.

Shein’s emissions are especially high because of its reliance on air shipping, said Sheng Lu, a professor of fashion and apparel studies at the University of Delaware. “AI has wide applications in the fashion industry. It’s not necessarily that AI is bad,” Lu said. “The problem is the essence of Shein’s particular business model.”

Other major brands ship items overseas in bulk, prefer ocean shipping for its lower cost, and have suppliers and warehouses in a large number of countries, which cuts down on the distances that items need to travel to consumers.

According to the company’s sustainability report, 38 percent of Shein’s climate footprint comes from transportation between its facilities and to customers, and another 61 percent come from other parts of its supply chain. Although the company is based in Singapore and has suppliers in a handful of countries, the majority of its garments are produced in China and are mailed out by air in individually addressed packages to customers. In July, the company sent about 900,000 of these to the US every day.

Shein’s spokesperson told Grist that the company is developing a decarbonization road map to address the footprint of its supply chain. Recently, the company has increased the amount of inventory it stores in US warehouses, allowing it to offer American customers quicker delivery times, and increased its use of cargo ships, which are more carbon-efficient than cargo planes.

“Controlling the carbon emissions in the fashion industry is a really complex process,” Lu said, adding that many brands use AI to make their operations more efficient. “It really depends on how you use AI.”

There is research that indicates using certain AI technologies could help companies become more sustainable. “It’s the missing piece,” said Shahriar Akter, an associate dean of business and law at the University of Wollongong in Australia. In May, Akter and his colleagues published a study finding that when fast-fashion suppliers used AI data management software to comply with big brands’ sustainability goals, those companies were more profitable and emitted less. A key use of this technology, Atker says, is to closely monitor environmental impacts, such as pollution and emissions. “This kind of tracking was not available before AI-based tools,” he said.

Shein told Grist it does not use machine-learning data management software to track emissions, which is one of the uses of AI included in Akter’s study. But the company’s much-touted usage of machine-learning software to predict demand and reduce waste is another of the uses of AI included in the research.

Regardless, the company has a long way to go before meeting its goals. Grist calculated that the emissions Shein reportedly saved in 2023 — with measures such as providing its suppliers with solar panels and opting for ocean shipping — amounted to about 3 percent of the company’s total carbon emissions for the year.

Lenier, from Sustainable and Just Future, believes there is no ethical use of AI in the fast-fashion industry. She said that the largely unregulated technology allows brands to intensify their harmful impacts on workers and the environment. “The folks who work in fast-fashion factories are now under an incredible amount of pressure to turn out even more, even faster,” she said.

Lenier and Lu both believe that the key to a more sustainable fashion industry is convincing customers to buy less. Lu said if companies use AI to boost their sales without changing their unsustainable practices, their climate footprints will also grow accordingly. “It’s the overall effect of being able to offer more market-popular items and encourage consumers to purchase more than in the past,” he said. “Of course, the overall carbon impact will be higher.”

poking around trying to figure out how harmful semisynthetics (rayon/viscose/tencel etc) are to the environment.

https://envirobites.org/2019/07/09/the-fabric-cycle-generating-microplastics-from-our-laundry/

article 1 is a summary of two studies finding that cotton + rayon produce more microfibres than polyester, but that they have significant biodegration (~76 and ~62% respectively) after 243 days in simulated ocean environments while polyester had only biodegraded 5%. it makes sense—rayon is a cellulose fibre (by definition not a plastic), so its microfibres are going to dissolve better.

link 2 is to a study on identification of microfibres in the environment. its introduction cites some studies that found concerning amounts of cellulose microfibres in fish and ocean environments. they investigated the methods by which people were differentiating between naturally occurring and manmade cellulose. it’s more of a jumping-off point, and i’m going to keep reading things.

i started looking into this because i saw a post and a few articles lumping semisynthetic fabrics in with microPLASTICS, which is untrue. they do release microFIBRES, and there are vast amounts of wastewater and harmful substances involved in their production, but they’re not shedding plastics because they don’t contain plastic.

this document from the US govt, for example, has good advice for preventing microfibre shed but calls rayon plastic-based.

here’s how to prevent shed (and incidentally prolong the life of your clothes + get them cleaner for cheap):

wash in COLD WATER on a gentle cycle

use less detergent (you only need 2 tablespoons max)

wash less often (pants etc that aren’t dirty don’t need to be washed)

use laundry bags for delicates/fabrics that are prone to pilling (sign of weaker fibres)

apparently you can install a filter on your own machine to catch microfibres before they enter the water system. haven’t tried this one myself but i’m looking into it.

speaking as a sewist + textile enthusiast, the above tips are what you should be doing anyway for the health of your clothes. and now we know it helps the environment too!

Week 1: Sensory Challenge

Include at least one of the five senses in your microfic: sight, sound, smell, taste, or touch.

Examples

Her lips were softer than she thought they’d be, considering how wild the woman attached to them is. She tasted of cinnamon and something decidedly smokey. Hermione was hooked after the first taste. Bellatrix couldn’t believe the girl would be so brave as to kiss her, although she probably should’ve. The girl was Gryffindor’s Golden Girl after all.

draco was swaddled in silks immediately after birth, even before the vernix was removed. his sheets, night clothes (they were far too fancy to be just pajamas), and favorite ribbon were all of the finest silk. his skin never suffered that abomination of rayon and polyester blend that some of his peers thought silk. and yet nothing — nothing — felt as good on his skin as harry’s tattered def leopard tee, made from the most common cotton.

Using Cartridge Collectors in Steel Industries

1. Working Principle and Characteristics of Cartridge Dust Collectors

1.1 Working Principle

Cartridge dust collectors use cartridges as the filtering element and employ pulse jet technology for dust removal. The working principle involves dusty air being sucked into the housing through the dust hood, ducts, and air inlet. As the air flow suddenly expands and interacts with the air distribution plate, larger dust particles fall directly into the dust hopper due to gravity and inertia. Smaller and lighter particles pass through the cartridge, where they are captured by the filter material through Brownian diffusion and sieving effects. After backflushing, the dust falls into the dust bin for recycling, while clean air is discharged through the exhaust pipe with the help of a fan.

1.2 Advantages

1.High Dust Removal Efficiency: The cartridges use imported polyester fibers as filter media. They feature a layer of ultra-thin sub-micron fibers that effectively block most sub-micron dust particles, achieving a filtration efficiency of up to 99.99%, meeting ultra-low emission standards.

2.Low Operating Resistance: Thanks to the large filtration area and low filtration velocity, the operating resistance typically does not exceed 1000 Pa. This reduces the operational load and costs of the dust collection system.

3.Compact Structure: The design of the cartridges occupies minimal space, making installation and replacement easier. Cartridges are generally shorter than bag filters, simplifying construction and maintenance.

4.Long Service Life: The cartridges use durable polyester fibers, allowing a lifespan of over three years. This reduces the frequency of replacements and maintenance efforts.

5.Reusable: Polyester cartridges and membrane-covered cartridges can usually be washed with water and reused, lowering procurement costs.

1.3 Disadvantages

1.Poor Suitability for Moist, Sticky Waste Gas: In humid environments, cartridges can become blocked, requiring downtime for replacements, which affects production efficiency.

2.Higher Costs: The price of cartridges is over five times that of standard bag filters, leading to higher overall construction costs.

3.High Requirements for Airflow Uniformity: Uneven airflow can cause certain cartridges to experience excessive filtration velocity, which shortens their lifespan.

4.High Manufacturing Quality Requirements: The folded structure and quality of the cartridge seals directly affect operational performance, necessitating strict quality control.

2. Characteristics of Smoke and Dust in Various Steel Production Processes

Steel enterprises produce various types of smoke and dust, which differ significantly across processes:

2.1 Sintering Raw Material Area

Due to transportation issues, both domestic and foreign ores generally have a moisture content above 6%. The use of enclosed storage sheds and spray dust suppression further exacerbates dust emissions.

2.2 Sintered Product and Ore Bin Area

1.Sintered products generate dust particles ranging from 0.8 to 61.0 μm during transport, with moisture content below 1%.

2.Blast furnaces commonly use heated grinding techniques, with particles below 200 mesh comprising 76% to 84%, and moisture content also below 1%.

3.During coke transportation, the moisture content is below 1% for dry quenching processes, while wet quenching processes often exceed 10%.

2.3 Converter Steelmaking Area

1.Fluxes used in converters typically have a moisture content of 1.0% to 1.5%.

2.Dust generated during the steelmaking process has over 98% of particles larger than 5 μm, with low temperatures.

3.The moisture content of dust from converter slag handling often exceeds 10%.

2.4 Rolling Steel Production Area

Wet gas emissions during rolling processes usually exceed 10% humidity, primarily due to water cooling.

2.5 Coking Production Area

1.Coal dust generated during the coking preparation area often has a moisture content above 6%, with over 99% of particles larger than 2 μm.

2.The dust particle size during coal pushing generally ranges from 3.3 to 4.7 μm, with waste gas humidity between 1% and 5%.

2.6 Flux Production Area

During the transport of limestone and finished lime, over 95% of dust particles exceed 10 μm, with moisture content below 1%.

3. Recommendations for Using Cartridge Dust Collectors in Steel Enterprises

1.Avoid Collecting High-Humidity Waste Gas: This includes waste gas from iron ore in the sintering preparation stage and from wet coking processes.

2.Use Caution with Sticky Waste Gas: This applies to dust generated during lime transport and in the coking process.

3.Optimize Inlet Design: Lower the inlet airspeed of the cartridge dust collector and improve internal airflow distribution to ensure uniform flow among cartridges.

4.Ensure Uniform Backflushing Airflow: The length of the backflushing nozzle should be maximized to maintain even airflow distribution.

5.Strictly Control Cartridge Quality: Ensure that the technical parameters of folded cartridges meet relevant standards. Inspect the quality of the membrane and uniformity of folds, and verify the manufacturing process of the cartridge seals.

In conclusion, cartridge dust collectors hold significant promise for use in steel enterprises. However, optimizing design and usage strategies based on specific operating conditions is essential to enhance dust removal efficiency and cost-effectiveness. Choose Darko’s cartridge dust collectors for outstanding performance and reliable solutions.
