the Council for Textile Recycling, charities overall sell only 20 percentof the clothing donated to them at their retail outlets. All the big charities I contacted asserted that they sell more than that—30 percent at Goodwill, 45 to 75 percent at the Salvation Army and 40 percent at Housing Works, to give a few examples. This disparity is probably because, unlike small charity shops, these larger organizations have well-developed systems for processing clothing. If items don’t sell in the main retail store, they can send them to their outlets, where customers can walk out with a bag full of clothing for just a few dollars. But even at that laughably cheap price, they can’t sell everything.
“When it doesn’t sell in the store, or online, or outlets, we have to do something with it,” says Michael Meyer, vice president of donated goods retail and marketing for Goodwill Industries International. So Goodwill—and others—“bale up” the remaining unwanted clothing into shrink-wrapped cubes taller than a person and sell them to textile recyclers.
This outrages people who believe the role of thrift shop charities is to transfer clothes to the needy. “What Really Happens to Your Clothing Donations?” read a Fashionista headline earlier this year. The story hinted, “Let’s just say they’re not all going towards a good cause.”
“People like to feel like they are doing something good, and the problem they run into in a country such as the U.S. is that we don’t have people who need [clothes] on the scale at which we are producing,“ says Pietra Rivoli, a professor of economics at Georgetown University. The nonprofit N Street Village in Washington, D.C., which provides services to homeless and low-income women, says in its wish list that “due to overwhelming support,” it can’t accept any clothing, with the exception of a few particularly useful and hard-to-come-by items like bras and rain ponchos.
Fast fashion is forcing charities to process larger amounts of garments in less time to get the same amount of revenue—like an even more down-market fast-fashion retailer. “We need to go through more and more donations to find those great pieces, which can make it more costly to find those pieces and get them to customers,” says David Raper, senior vice president of business enterprises at Housing Works. Goodwill’s strategy is much the same, says Meyer: “If I can get more fresh product more quickly on the floor, I can extract more value.”
This strategy—advertising new product on a weekly basis—is remarkably similar to that of Spanish fast-fashion retailer Zara, which upended the entire fashion gameby restocking new designs twice a week instead of once or twice a season. And so clothing moves through the system faster and faster, seeking somebody, anybody, who will pay a few cents for it.
International companies like Adidas, Levi’s, Nike and H&M don’t want you to stop buying their products, but they also don’t want to give up on their fast-fashion business models. “The holy grail for sustainability in fashion is closed-loop sourcing,” Marie-Claire Daveu of the global luxury holding company Kering toldVogue. (Kering owns companies like Gucci, Alexander McQueen, Saint Laurent and Stella McCartney, among many others.) “Reuse old materials. Make new materials out of old materials. Recapture the fibers.”
Closed-loop technology, where a product is recycled back into almost the same product, is a tantalizing prospect for sustainability advocates, because it essentially mimics the natural process of life. A plant grows out of dirt, dies, is incorporated back into dirt, and then another plant grows from that dirt. Rain falls, moves through the forest and into a river, flows to the sea, evaporates into the sky and falls again. There’s no waste. If closed-loop technology could be achieved for fashion, nothing would ever go the landfill—it would just be endlessly looped through textile factories, garment factories, stores, your closet, secondhand retailers, textile recyclers and back to textile factories again. Polyester thread would be created, woven into a textile, made into a garment, broken down into pure polyester and woven into a textile again. Same for natural fibers.
But commercially scalable, closed-loop textile recycling technology is still five to 10 years away, at best. According to a 2014 report commissioned by the Sustainable Apparel Coalition, there is closed-loop technology for pure cotton that could take a garment, break it down and reweave—but once cotton is dyed, treated or blended with other materials, the process no longer works. Treated cotton, linen, silk and wool can be mechanically chopped up for recycling, but they yield a low-quality, short fiber that must be mixed with virgin fiber for clothing. At 20 percent reused cotton, H&M’s recycled denim line released last summer pushed the limits of what’s possible today—a higher percentage of recycled cotton results in a lower-quality textile that tears too easily to be wearable.
A hopeful note appeared in May when Levi’s debuted a prototype of jeans in partnership with the textile technology startup Evrnu, made with a mix of virgin and chemically recycled cotton from old T-shirts. Evrnu says its technology isn’t sensitive to certain dyes, and it hopes to eventually make jeans from 100 percent post-consumer cotton waste. But they never tested the jeans, so don’t know what percent of the denim was the recycled cotton. Plus, there’s no timeline available yet for when these jeans will become available.
Closed-loop recycling of synthetic textiles like elastane-nylon blends is even further away from commercial feasibility. The technology exists to chemically process polyester into its core components and spin it back into polyester thread, and Patagonia is already using it to recycle its clothing. But Patagonia is doing it out of principle, not for profit; the process is prohibitively expensive and finicky, requiring high-quality polyester textile (Patagonia’s own fleeces) as an input, instead of the cheap polyester textiles typically used by fast-fashion retailers.
