Every year 12.7 million tonnes of plastic seeps its way into the oceans, with some of it even getting trapped in the Arctic ice, lodged in the bellies of marine life and caught around turtle’s necks. As a result, many fashion brands are taking this as an opportunity to incorporate regenerated yarns into their collections. But is this a sustainable future for fashion and our planet?

Technology and fashion have merged to produce Bionic and Econyl yarns, which are being made from discarded plastic in the oceans. From water bottles to takeaway containers and even old fishing nets, it seems fashion has repurposed plastic firmly on its agenda. This plastic is being recycled into usable yarns for the creation of garments like trainers, sportswear, lingerie and even dresses.

These yarns are increasingly being used by local and global brands to create all types of textile products. Not only is this integration removing plastic from the oceans and reusing it, it’s also helping to improve local communities. Two years ago twelve tonnes of abandoned fishing nets were collected from the Basque region and turned into Econyl yarn; this is still being utilised today, forming part of clothing brand Ternua’s autumn winter 2018 collection.

But there are problems with repurposing plastic into garments. When any synthetic clothing is washed, tiny plastic fibres can be released from the fabrics and these microplastics can make their way into water systems. According to Mark Anthony Browne in Environmental Science & Technology, one single synthetic garment can produce nearly 2,000 microfibers per wash. As of July 2018, these microplastics—which are comparable to cosmetic beads—are going to be banned from sale in the U.K. because of the threat they pose to marine life as they find their way into food chains and cause serious harm to aquatic life. At the same time, the microscopic dimensions of these plastics means they cannot always be filtered by sewage systems, proving a real concern to the environment.

At the moment, fashion made from synthetic material is inevitable, it is and will be used to make throwaway fashion for the foreseeable future. The most common synthetic textile is polyethylene terephthalate (polyester), a plastic produced from crude oil and also used to create many other household items, from hosepipes to ketchup bottles. It is predicted that more than 98 percent of fiber production in the future will be synthetics, and of this, 95 percent will be polyester. Sure, repurposing old plastic is better than producing more. Yet a more long term solution would be to encourage the fashion industry to further push towards making garments from sustainable sources that will not prolong harmful effects on the environment.

Two fashion students in Delaware have created biodegradable shoes using a part of a mushroom called the mycelium, chicken feathers and textile waste. It is local innovation like this that will lead the fashion industry. Jillian Silverman, co-maker of these shoes said to Screen Shot, “Mycelium has been used in hard structures like packaging and insulation, and our proximity to the mushroom farms in Kennett Square, Pennsylvania, provided us with a great local material input.”

Aside from fabrics, there are other factors to making fashion entirely sustainable, especially for larger brands. Silverman continued, “The textile industry needs more sustainable production methods, materials, and end of life considerations; mycelium shoe sole can be produced with minimal energy, is nontoxic and safe to work with and wear, and can safely break down when it is no longer useful. Plenty of other bio-based materials offer similar benefits, and this sort of innovation is crucial to improving the apparel and footwear industries.”

The concept of producing clothing from yarns made from regenerated ocean plastic, in theory is a revolutionary idea, but the repercussions that result from washing synthetic fabrics does not actually improve the environmental problem of microplastics. Plastic conscious clothing is appealing to customers who are becoming more aware of environmental impacts but this cannot be seen as the final goal of the sustainable fashion trend. If synthetic clothing is an essential part of the fashion industry (and it shouldn’t be), then using old plastic that is polluting the sea is certainly better than creating more. Yet ideally fashion would look to use only sustainable and biodegradable fabrics to create garments like Silverman’s project and only when this happen—and other impacts like waste reduction, manufacturing practises and human impacts are improved—can fashion be praised for a lesser impact on the environment.

In 2015, designer and creative director Matthew Williams decided to channel his vision towards the creation of his own fashion brand 1017 Alyx 9SM. Following an already praised career during which he worked as a creative director with celebrities like Kanye West and other top fashion designers, since the founding of Alyx, Williams has added outstanding collaborations with brands like Moncler, Nike, and Dior Men to his impressive catalogue. Constantly pushing the boundaries of design, technology, and sustainability, Williams announced recently that Alyx was going to be the first brand to introduce blockchain technology to unveil the garment production in a way that is 100 percent accurate.

Sustainability has been part of the brand’s agenda from its start. Alyx uses recycled materials, as well as a leather dyeing process that consumes CO2, and has always been transparent about who—and under what working conditions—the collections have been produced by. Working closely with the worldwide leader in adhesive technologies Avery Dennison and the Internet of Things (IoT) software company Evrythng, Alyx has now implemented supply chain transparency into the brand by launching a blockchain-powered pilot programme on nine of its garments. Taking the brand’s history into consideration, it feels like a natural yet visionary step forward to add blockchain ledgers to its supply chain, making it visible and understandable to clients.

The nine products’ tags now feature a scannable QR code that reveals the entire supply chain history of the garment. According to Vogue Business, the data—which can be accessed by phone—include information about where the materials were sourced, where the product was manufactured, and its shipping movements. With 80 percent of its garments produced in Italy, the process of uploading and tracking the data of the garments is easily doable for Williams. In this transparency procedure, each supplier is in charge of entering the data into the chain.

Not only is this change innovative, but it could also prove the implementation of this feature to be a crucial addition to the brand’s history, and, if it works, to other fashion brands. “That’s what we want to continue to communicate, and that’s what brings value to our pieces,” Williams said. “It becomes a really great storytelling element”. Alyx belongs to that category of brands which promote durability rather than fast-fashion consumerism. In this regard, Williams and Dominique Guinard, founder and chief technology officer at Evrythng, believe that by knowing the digital identity of one garment, or its ‘journey’, customers might get more attached to the product. In an industry where overproduction and exploitation are toxic constants, sustainability and transparency are increasingly demanded by consumers. Alyx’s experimentation with blockchain technology stands as one of the finest examples of fashion innovation. By exposing its own brand’s data, Williams seeks to inspire a new approach in fashion, calling for other designers to follow suit.

The sustainable production process behind Alyx’s collections, which is now traceable thanks to the new technology, makes sure that its aesthetic is coherent with the message. The use of innovative technologies and the emphasis on transparency never overshadow the technical and aesthetic research that makes the brand’s design so on point. Some say that Alyx anticipates design trends, I’d argue that Alyx is doing way more than that. It is paving a path for a new way of thinking about fashion, technology, and most importantly, an industry future that is sustainable.
