Call it the H&M effect, or fast fashion. Americans are buying, and discarding, clothes more quickly than ever. On average, each of us throws 54 pounds of clothes and shoes into the trash each year. That adds up to about 9 million tons of shoes, jackets and other wearables that are sent into the waste stream annually, according to the
Traditionally, the options for dealing with that waste have started with an R: Reduce, reuse or recycle. But a clutch of designers, some of them high-end, are pursuing a different tack. They're producing clothing and accessories that are biodegradable — or at the very least, have parts that are capable of decomposing into natural substances. The movement is still in its infancy, but it's an important development in an industry that's increasingly scrutinized for its wastefulness.
"Everyone is beginning to appreciate the need to reduce fashion's impact on the environment," said Alex McIntosh, business and research manager for the Centre for Sustainable Fashion at the London College of Fashion. "Compostability is part of a wider waste management agenda" that is likely to grow in coming years, even if its use is only beginning in the $774-billion global apparel manufacturing business.
Of course, it's unlikely that anyone who invests $500 in a pair of designer shoes or glasses would throw them in the trash and even less likely that such a rarefied buyer would toss a luxury item onto a compost pile. But "it's great that high-end designers are exploring these ideas as their influence has an impact on the collective psyche of the design community," McIntosh said.
That's certainly the case with Stella McCartney, the well-known vegetarian designer whose shunning of leather and fur created more acceptance of synthetic alternatives in high fashion. McCartney is often credited with turning faux furs and leather handbags into a fashion "do" when such materials had long been considered too down-market. Now designers including Calvin Klein and
McCartney's partly biodegradable pumps, which feature 4-inch heels and thick white soles reminiscent of gym sneakers, went on sale in September. Only the soles, made from plant-derived plastic, are biodegradable. But their inclusion reflects McCartney's philosophy that "doing a little something is really a lot better than doing a lot of nothing."
Her new Stella lingerie line incorporates recycled metal hardware and organic cotton gussets. All of her sunglasses are now eco-friendly. They are made with more than 50% organic materials derived from castor oil seeds and sugar.
Gucci began incorporating more castor oil seed plastic into its sunglasses in 2011. This year, the company introduced sunglasses made with biodegradable frames and plant-derived, bio-plastic ballerina flats and sneakers.
Like Stella McCartney's pumps, though, Gucci's Liquid Wood sunglasses and California Green sneakers aren't entirely biodegradable. They're made from a mix of materials. Only the soles of the low- and high-top men's sneakers are made from plant-based plastics that decompose over time without leaving chemicals or other harmful substances behind. The Gucci logo is fashioned from recycled polyester. The uppers are made with vegetable tanned leather.
As for the sunglasses, the frames are made from wood fiber and natural wax. The metal joints are constructed with recycled metal, which points to the difficulties of making items that will entirely decompose: Only 100% natural fashions, such as cotton T-shirts stitched with cotton thread, can easily, and completely, break down in combination with heat, moisture and time. Not everything can be made so simply; indeed, consumers have come to expect certain performance levels from sophisticated fabrics, such as cotton-spandex blends.
"With textiles, you get monstrous hybrids," said Susanna Schick, owner of Sustainable Fashion L.A., an environmental consulting firm. "Having spandex in something makes it much easier to wear, but if you put spandex in cotton, it's a petroleum-based fiber with an organic fiber, so the cotton will decompose but the spandex won't. It's a difficult situation."
And it's one that isn't likely to go away.
"When it comes to fashion, we need to design products that can either go safely back into the biosphere, meaning they would be compostable, or safely become technical nutrients, such as polymers, metals and polyester, that can be recycled into new products," said Lewis Perkins, senior vice president of the Cradle to Cradle Products Innovation Institute in San Francisco. "We need to eliminate the concept of waste from our vocabulary and instead think of every material as a potential nutrient for future products. That will be the direction we need to head as a planet as we support 10 billion-plus people."
While biodegradability is a step in the right direction, Perkins said the more important development in sustainability in fashion is using more technical fibers such as polymers that can be recycled (or continuously used) since fashions made from natural materials are so water- and energy-intensive.
Almost 13 million tons of textile waste are generated annually, according to the EPA. Of that, just 14% of the textiles used in clothing and footwear is recovered for reuse or recycling. Statistics do not exist for how much textile waste is composted, but it's probably minuscule. Still, more designers are seeing its potential — and not only at the high end. Many small start-ups are also experimenting.
The Dutch footwear company Oat has been making entirely biodegradable sneakers since 2011. Dizm Eyewear, in Hermosa Beach, began selling sunglasses with biodegradable frames this spring. Last year, fashion and engineering students at Sheffield Hallam University in England jointly developed a wedding dress knitted from biodegradable polyvinyl alcohol thread that's designed to dissolve into water without releasing harmful chemicals into the environment. Another British designer, Suzanne Lee, has experimented with "growing" fabric. She uses a bacterial cellulose made from kombucha, a fermented tea that Lee grows into sheets that can be molded into a seamless garment and buried in the garden at the end of its useful life.
L.A. designer Linda Loudermilk made a splash in 2010 with a compostable bikini that can completely decompose in 180 days. In addition, for the last four years, Loudermilk and her team have been working with a lab to develop a plant-based fabric that breaks down quickly. In November, Loudermilk will launch a compostable "luxury eco" line of shampoos, conditioners, cosmetics and fragrance, along with cutting capes for hair salons made with the same compostable fabric as the bikini.
Just like fashion, where one size usually does not fit all, different types of clothing require different sustainability strategies. Fashions that readily biodegrade may be better suited for the most disposable, least recyclable items in a wardrobe, such as undergarments, swimsuits or so-called fast fashion, which is, by its very nature, cheap and disposable.
