Are clothes made from recycled materials really more sustainable? | Environment

Woven into your clothes is a fabric that takes on many disguises. It might have the feel of wool, the lightness of linen or the sleekness of silk. It’s in two-thirds of our clothes – and but most of us don’t even know that it’s there. It’s plastic, and it’s a giant downside.

At this time, about 69% of clothes are made up of artificial fibres, together with elastane, nylon and acrylic. Polyester is the commonest, making up 52% of all fiber manufacturing. Plastic’s distinctive sturdiness and flexibility have made it indispensable to the style {industry}.

“It’s within the waistband of your denims, your sneakers, in virtually every part you put on, as a result of plastic is that this miracle materials,” mentioned George Harding-Rolls, campaigns adviser on the Altering Markets Basis, a company that investigates company practices.

However there’s a local weather value: the uncooked materials for these fibers is fossil fuels. Textile manufacturing consumes 1.35% of global oil production, more oil than Spain makes use of in a 12 months, and considerably contributes to the style {industry}’s large local weather footprint. Synthetics additionally proceed to have an effect lengthy after manufacturing, shedding plastic microfibers into the surroundings when clothes are washed.

In response, a rising variety of manufacturers are switching to recycled variations of artificial fibers like polyester, usually promoting these clothes because the “more sustainable” or “conscious” alternative.

This looks as if an environmental win. However as manufacturers weave more of those recycled yarns into their clothes, some consultants query whether or not they’re simply patching over trend’s environmental harms. “We’ve been led to consider that recycled and sustainable are synonymous, when they’re something however,” mentioned Maxine Bédat, govt director of the New Commonplace Institute, a non-profit pushing for a sustainable trend {industry}.

The frequent recycled substitute for virgin synthetics are polyethylene terephthalate (PET) bottles, the commonest kind of plastic bottles, that are produced within the billions annually. A survey of almost 50 trend manufacturers by the Altering Markets Basis revealed that 85% of them aimed to supply recycled polyester from plastic bottles. Estimates present that recycled polyester might scale back emissions by up to 32% in comparison with virgin polyester.

The demand for recycled synthetics from industries together with trend is expected to accelerate. Nike makes use of “some recycled materials” in 60% of its merchandise, mentioned Seana Hannah, Nike’s vice-president of sustainable innovation. Recycled polyester is a main focus: “Nike is the best {industry} consumer of recycled poly and we divert more than 1bn plastic bottles on common a 12 months from landfills,” Hannah mentioned.

Many huge manufacturers are setting targets. H&M, Madewell, J Crew and Hole Inc are amongst more than 70 brands which have dedicated to extend the share of recycled polyester to 45% by 2025 as a part of a recycled polyester challenge set by the Textile Change, a non-profit working to extend uptake of lower-impact fibers throughout the textile {industry}.

Synthetics make up the second-largest share of fibers after cotton for Hole Inc, mentioned Alice Hartley, director of product sustainability and circularity on the firm. All 4 of its manufacturers – Banana Republic, Previous Navy, Athleta and Hole – have dedicated to the 2025 problem, with Previous Navy opting to extend its recycled polyester to 60%.

The corporate says that recycled synthetics usually are not a magic bullet. “We really attempt to keep away from the time period ‘sustainable garment’, as a result of that means that we’ve reached the vacation spot. We really haven’t, it’s a steady journey,” Hartley mentioned.

But this nuanced message might not be filtering via to customers, particularly as many different manufacturers do describe recycled materials as sustainable. Specialists fear that folks might consider their purchases are impact-free – when that’s far from true.

“If you’re recycling synthetics, that doesn’t eliminate the microplastics downside,” mentioned Harding-Rolls. Fibers proceed shedding from recycled plastic yarns simply as a lot as from virgin yarns, he mentioned.

PET bottles are additionally a part of a well-established, closed-loop recycling system, the place they are often effectively recycled at least 10 times. The attire {industry} is “taking from this closed-loop, and transferring it into this linear system” as a result of most of these clothes gained’t be recycled, mentioned Bédat. Changing plastic from bottles into clothes may very well speed up its path to the landfill, particularly for low-quality, fast-fashion clothes which are sometimes discarded after only a few uses.

“One of many hallmarks of greenwashing is taking one piece of the puzzle and extrapolating broad advantages from that,” mentioned Ashley Gill, senior director of requirements and stakeholder engagement Textile Change. “Sustainability within the attire {industry} is a really advanced concern.”

There are strikes to make use of recycled textiles as feedstock for brand spanking new clothes – lower than 1% of clothes are at the moment recycled into new fibers – particularly as projections from some markets recommend that cross-industry demand for recycled bottles will soon outstrip supply. However most clothes are made from a medley of fibers, and commercial-scale know-how doesn’t but exist to disentangle these. “A complete provide chain must be constructed as much as really get to the industrial volumes that we’d like, to see more recycled fiber-to-fiber textiles,” Hartley mentioned.

Hyping the decrease emissions impression of recycled yarns, mentioned Bédat, distracts from trend’s bigger emissions supply: textile mills, which course of fibers into yarn to make cloth in addition to dyeing and ending, an energy-guzzling course of that accounts for about 76% of a garment’s lifecycle emissions. “Manufacturers are specializing in what magical materials they’ll create, quite than doing the much less attractive work of enhancing vitality effectivity in textile mills,” mentioned Bédat. “I don’t need to pooh-pooh progress, however we really do have to begin prioritizing the place we’re going to have the ability to transfer the needle probably the most.”

Some innovators suppose the answer lies find viable options to fossil fuel-derived synthetics which have the identical efficiency traits. Materials science firm Kintra Fibers has developed bio-based fibers made from corn and wheat designed to compost absolutely in nature. “That addresses the microfiber concern, and gives one other pathway for textile circularity as nicely,” mentioned Alissa Baier-Lentz, the corporate’s co-founder.

The fiber can be returned to its base parts via chemical recycling and used as a feedstock for round yarn manufacturing, Baier-Lentz mentioned. “It’s simply on us to get the [recycling] system in place, and work with {industry} companions to make it occur,” she mentioned. In 2020 Kintra partnered with clothing brand Pangaia to scale up manufacturing of the compostable yarn; the corporate will launch the primary clothes made with Kintra fibers in 2022.

However nobody innovation goes to resolve the style {industry}’s advanced plastics downside. Some suppose the actual reply is transferring the {industry} away from a mannequin of extreme manufacturing and consumption. Manufacturers churn out dozens of clothing collections a 12 months and, in 2014, individuals purchased 60% more clothing than in 2000 however stored it for half as lengthy. Textile Change will focus a few of its future {industry} challenges on “slowing down the expansion price” of clothes manufacturing, mentioned Gill.

Laws will probably be wanted to drive actual, systemic change, mentioned Harding-Rolls: “[The apparel industry] is without doubt one of the most calmly regulated industries on the planet. What we’d like now are obligatory measures. We see it working within the plastics house, and it’s time for the style sector to comply with.”

There’s a task for us, too, mentioned Bédat, and that includes individuals seeing themselves as residents who could make moral and political selections. “We’ve been educated to see ourselves primarily as customers … that the best way we remedy these issues is by shopping for, which is the antithesis to the actual answer.”
