Circular Economy

For a True War on Waste, the Fashion Industry Must Spend More on Research

Posted on Updated on

by Mark Liu

The rise of fast fashion in Australia means 6000 kg of clothing is dumped in landfill every 10 minutes. The ABC’s War On Waste visualised this statistic by piling a giant mound of clothing waste in the middle of the city. So what to do about it?

Sustainable fashion experts advocate abstaining from buying fast fashion, promoting clothing swaps and repairing old clothing. Others suggest buying organic and ethically-sourced clothes or designing clothing using zero waste techniques. The hope is that greater transparency in supply chains will lead to an end to sweatshops and unsustainable fashion practices.

These are admirable initiatives, but they only reduce wastage or delay garments from ending up in landfill. They do not address the fact that the scale of fast fashion is so massive it can easily eclipse other sustainability initiatives. Nor do they address the wastefulness of existing technologies and the urgent need to research new ones.

Even if we could magically stop the global production of all garments, we would still need new, green technology to clean up the waste we have already created. There are long-term strategies for green technologies such as electric cars, but where are the major companies and research institutes developing the next generation of sustainable fashion technologies? The development of new synthetic biology technologies may be the key.

From catwalk to research

I would like to share my journey from zero waste fashion design pioneer to trans-disciplinary fashion researcher to highlight the challenges faced by sustainable fashion and the need for more research.

Ten years ago, I presented my “Zero-Waste” Fashion collection at London Fashion Week. I and other sustainable designers at the time took the waste streams of other industries such as scrap materials and leftover fabric and created our collections from them. I was selected for “Estethica”, a new initiative created by sustainable fashion gurus Orsola De Castro, Filippo Ricci and Anna Orsini from the British Fashion Council. Sustainable fashion was shown on London catwalks next to luxury fashion – a revolutionary step for the time.

I pioneered a way of creating tailored, high fashion garments so that all the pieces of a garment fitted together like a jigsaw puzzle and no waste was created. Conventional pattern cutting creates about 15% wastage of material, even if the pattern has been optimised by a computer. I wanted to systemically change the way clothing was made.

To design a garment with zero waste requires new patternmaking techniques, based on advanced mathematics. Author provided

But the problem with zero-waste design is that it is very difficult to create. It requires a skilled designer to simultaneously imagine the garment as a 3D item and a flat pattern, while trying to fit the pieces together like a jigsaw. It is easy to make an unfitted or baggy garment, but creating something that looks good and fits the body was a real challenge.

Even after all these years, most contemporary zero-waste fashion is still not tailored to the body. I practised this technique for years to master it. It required breaking all the rules of conventional pattern-making and creating new techniques based on advanced mathematics.

These were exciting times. Our fabrics were organic, we made everything locally and ensured everyone was paid an ethical wage. The press loved our story. But problems started to emerge when it came to sales. We had to sell more expensive garments, using a smaller range of fabrics – our materials and labour costs were higher than those of companies that produced overseas. Often fashion buyers would say they loved what we did, but after looking at the price tag would politely take their business elsewhere.

As a sustainable fashion designer, my impact was limited. It was also impossible to teach zero-waste fashion design without explaining how advanced mathematics applied to it. It was time to try a new approach, so I decided to apply science and maths to traditional fashion techniques.

My PhD research explored the underlying geometry of fashion pattern-making. Combining fashion with science allowed the traditional techniques and artistry of making garments to be explained and communicated to scientist and engineers.

In the meantime, fast fashion companies rapidly expanded, with Zara, Topshop and H&M reaching Australia by 2011. They produced massive amounts of cheap products making low margins on each garment. Consumers quickly became addicted to the instant gratification of this retail experience. The size and scale of their production produced hundreds of tonnes of garments every day.

The limits of fashion technology

Fast fashion companies such as H&M have developed recycling initiatives in which consumers can exchange old clothing for discount vouchers. This is supposed to prevent clothing from going to landfill, instead recycling it into new clothing.

However, there are those who are sceptical of H&M’s recycling process. In 2016, investigative journalist Lucy Siegle crunched the numbers and concluded that “it appears it would take 12 years for H&M to use up 1,000 tons of fashion waste”. This, she said, was the amount of clothing they produce in about 48 hours.

A 2016 H&M sustainability report reveals that only 0.7% of their clothes are actually made from recycled or other sustainably-sourced materials. In the report, H&M acknowledges :

Today, this is not possible because the technology for recycling is limited. For this reason, the share of recycled materials in our products is still relatively small.

In fact, their 2016 annual report states that more research is needed:

if a greater proportion of recycled fibres is to be added to the garments without compromising quality, and also to be able to separate fibres contained in mixed materials.

Sustainable technologies strive for a “circular economy”, in which materials can be infinitely recycled. Yet this technology is only in its infancy and needs much more research funding. H&M’s Global Change Award funds five start-up companies with a total of 1 million Euros for new solutions. Contrast this with the millions required by the most basic Silicon Valley start-ups or billions for major green technology companies such as Tesla or SolarCity. There is a dire need for disruptive new fashion technology.

Many of the promising new technologies require getting bacteria or fungi to grow or biodegrade the fabrics for us – this is a shift to researching the fundamental technologies behind fashion items.

For example, it takes 2700L of water and over 120 days to grow enough cotton to make a T-shirt. However, in nature, bacteria such as “acetobacter xylinum” can grow a sheet of cellulose in hours. Clothing grown from bacteria has been pioneered by Dr Suzanne Lee. If a breakthrough can be made so that commercially grown cotton can be grown from bacteria, it may be possible to replace cotton fields with more efficient bacteria vats.

But why just stick with cotton? Fabrics can be generated from milk, seaweed, crab shells, banana waste or coconut waste. Companies such as Ecovate can feed fabric fibres to mushroom spore called mycelium to create bioplastics or biodegradable packaging for companies such as Dell. Adidas has 3D printed a biodegradable shoe from spider silk developed by AM silk.

Although I began my journey as a fashion designer, a new generation of materials and technologies has pulled me from the catwalk into the science lab. To address these complex issues, collaboration between designers, scientist, engineers and business people has become essential.

To clean up the past and address the waste problems of the future, further investment in fashion technology is urgently needed.

Can Rent the Runway Replace Fast Fashion?

Posted on Updated on

With a new same-day delivery service, it’s going to try.

By Eliza Brooke

When Rent the Runway launched in 2009, offering shoppers a relatively inexpensive way to rent out designer clothing for a few days, customers booked their outfits for weddings and special occasions three weeks ahead. Eight years later, that window has narrowed to days and, in many cases, hours.

“Our customers’ entire lives are on-demand,” says CEO Jennifer Hyman. “They’re not planning anything in advance.”

So to meet the wants of those Hotel Tonight-ing, Seamless-ing, Uber-ing shoppers, Rent the Runway is going on-demand, too. Today, it’s launching same-day delivery in New York, promising to deliver orders to shoppers by 5 p.m. if they book by noon.

You could say that Rent the Runway is trying to compete with Net-a-Porter and Barneys, both of which offer same-day delivery in parts of New York, or that it’s trying to get a slice (a sliver, really) of Amazon’s Prime Now action. But Hyman says that it’s mainly looking to cut into fast fashion’s stranglehold on day-of purchases. For women who work and live within subway distance of a Zara, it’s all too easy to put off buying something for a nice event until the very last minute, because you know that when you walk through those doors you’ll be able to find something that’s on-point and inexpensive, fast.

“Today, the only real options from a value perspective and a distribution perspective are H&M, Zara, T.J. Maxx, and Forever 21,” Hyman says. “If I get asked on a date tonight, the probability that I’m going to go all the way to Saks and spend $1,000 on that outfit is zero.”

Rent the Runway offers product from high-end designers like Oscar de la Renta, Giambattista Valli, and Proenza Schouler, but some of its dresses hit as low as $30. That’s the price point that could persuade people to test out its same-day service instead of hitting up a chain store. And for anyone who feels gross about the disposable clothing culture attached to the fast fashion industry, buying into Rent the Runway’s cycle of reuse (which does incur the environmental costs of dry cleaning) may be extra appealing.

In recent years, the startup has been trying to cement itself as a go-to for everyday clothing as well as event dressing, and it’s expanded its assortment accordingly with trousers and tops and rompers. Same-day delivery helps push it toward that goal.

Hyman says Rent the Runway is looking to expand same-day delivery to other major cities by the fall. If all goes well, Chicago, DC, LA, and San Francisco could be up next.

Cradle to Cradle: Fashion’s Grave Reality

Posted on Updated on

circular-vs-linear-fashion-cycle_1024x1024.jpg

The circular economy.

Closing the loop.

Cradle to cradle.

These are all phrases you may well have heard of. If not, best to familiarise yourself with them a.s.a.p. As our increasingly consumerist lifestyles reach tipping point, organisations are desperately trying to gather and reuse our rubbish, because otherwise, we may have nothing left to make anything with.

This year’s Copenhagen Fashion Summit was kicked off by someone I had, until that moment, not heard of: Bill McDonough. If you are as clueless as I was, take the next 14 minutes and 30 seconds to get to know him and his ideas a little better. You won’t regret it.

Interesting, right?

People were still clapping by the time I’d completed my purchase of his book, Cradle to Cradle.

Fashion’s grave reality

McDonough’s work is clearly applicable to the creation of many, if not all, products. But it is particularly relevant to clothing because this industry has arguably one of the most linear and wasteful cycles in modern society. And this cycle’s impact on the environment is exacerbated by its speed and the quantities involved.

take make dispose clothing lifecycle fashion

The fashion cycle: cradle to grave

With 92 million tonnes of textile waste being produced by the global fashion industry in 2015, corresponding to more than 12 kg per person, it’s clear that we are hemorrhaging valuable resources every second of every day.

So What Exactly is Being Wasted?

I recently wrote about the differences between natural and man-made fibres, and the importance, as a consumer, of understanding where these different fibres come from.

In particular, I highlighted popular man-made fibre polyester as the most used in clothing production today.

Polyester is derived from fossil fuels, one of our planet’s none renewable resources. A resource so valuable in fact, that it should be treated as a ‘nest egg’ McDonough suggests.

And yet, not only do we buy cheap, poorly made clothing using this precious resource, but we throw it out in such a way that these valuable materials cannot be retrieved.

Perhaps excavating landfill sites will be a common activity in the future?

How insanely backward would that be?

How Can the Fashion Industry Do It Better?

How can this regressive fashion industry transform itself into a regenerative one?

When it comes to fashion, and the materials we use, we can work to achieve a circular system in two ways:

By creating a “biological” cycle, whereby an item made with 100% natural fibres (wool for example), able to be broken down by bacteria, is reclaimed by nature into its vast ecosystem when we no longer want or require it.

clothing fashion lifecycle cradle to cradle biodegradable

The fashion cycle: cradle to cradle (biological)

Or a “technical” one, whereby the clothing we buy made of man-made fibres is designed in such a way that the fibres can be separated and reused in a never-ending production cycle, whilst not degrading in quality.

 

fashion clothing lifecycle recycle circular cradle to cradle

The fashion cycle: cradle to cradle (technical)

Some organisations are themselves working on large-scale collection schemes in their shops. These schemes provide them with the raw materials to experiment with ways of recycling fibres.TT

Unintelligent and Inelegant Things…

My favourite phrase from ‘Cradle to Cradle’ is: ‘products that are not designed particularly for human and ecological health are unintelligent and inelegant –what we call crude products

Everything we buy, and everything we do, is part of a bigger process.

We can’t know everything. But know this: as a wearer of clothes, what you chose to buy and wear really matters. Because with every purchase, you are telling the world who and what you support.

Choose not to buy cheap clothes from people who cannot tell you how or where their products are made.

Chose not to buy clothing from companies who ignore our collective responsibility to address the issues the fashion industry and, by default, we all face.

A product without background, without craftsmanship, made without thought or purpose or regard for the future is a product without beauty, without meaning and without worth.

It’s a crude purchase. Simple.

How NOT to Make the Fashion Industry More Sustainable

Posted on Updated on

This week, representatives from all the major brands – from fast fashion retailers like H&M, Asos and Zara, through to luxury labels like Burberry and Swarowski – are gathering in Copenhagen to discuss sustainability in the global fashion industry.

The fashion industry is one of the most lucrative and destructive industries on earth. It generates €1.5 trillion every year and produces over a billion clothes every year. With global garment production set to increase by 63% by 2030, this model is reaching its physical limit.

This year’s Copenhagen Fashion Summit is focusing  on “circularity” – an industry buzzword that promises relief to the problem of limited resources within one of the world’s most resource intensive industries. In 2015, the fashion industry consumed nearly 80 billion cubic meters of fresh water, emitted over a million tonnes of CO2 and produced 92 million tonnes of waste. The Summit admits that the industry has a disastrous environmental impact and that we face “increasingly higher risk of destabilising the state of the planet, which would result in sudden and irreversible environmental changes”.

While their focus on circularity sounds promising, it’s simply not enough.

Industry leaders rarely talk about the real solution: reducing the overall volume of production. All their talk about sustainable investing and innovative new materials and technologies comes under the assumption that the industry continues to grow. But unlimited growth is impossible on a planet with finite resources.

The industry wants to place the responsibility on consumers to educate themselves and recycle their own clothes, while continuing to heavily market cheap fast fashion at us.

Real change is not going to happen without investing in designs and strategies to extend the life of clothing and reduce the environmental impact of production at the design stage. Fashion brands need to redefine their marketing strategies and start involving customers in a new narrative where people buy less and clothes are more durable and repairable. We need to slow down.

It’s not enough to sell customers placebo solutions that ultimately leave shopping patterns untouched and guilt free. Even if we encourage people to recycle more, we have to remember that recycling is a resource intensive process relying on chemicals and vast amounts of energy, with many unsolved problems making it far from commercially viable.

We already know that we own more clothes than we can wear. Shopping doesn’t make us happy in the long run. High volumes of fast fashion and rapidly changing trends aren’t catering to our real needs.

If the Fashion industry really wants to be “an engine for a global and sustainable development”, it needs to think about how to shift the business model beyond the current paradigm of continuous economic growth. We hope that the fashion industry doesn’t wait until 2030 to realise that.

What “Going Circular” Means for the Apparel and Textile Industry

Posted on Updated on

The apparel and footwear industry is forecast to generate double-digit growth to 2020 according to business analysts McKinsey & Co. One of the challenges is reconciling this growth with sustainability initiatives. As this report states it, “Sustainability and rapid business growth are not compatible; to pretend otherwise would be disingenuous.”  The solution proposed is an alternative business model that is based on a closed-loop system.

A circular economy

The Ellen MacArthur Foundation describes the circular economy as being “restorative and regenerative by design, and which aims to keep products, components and materials at their highest utility and value at all times, distinguishing between technical and biological cycles.” In striving to achieve greater environmental responsibility, the notion of a circular economy is the latest iteration in creating a blueprint for industry.

In his book, Closing the Loop, Brett Matthews asks whether this laudable aim of infinite recycling is in fact realistic. The report is divided into seven sections and concludes with actionable recommendations and further reading resources. The first section gives an overview of the issue, definitions, and the global and local challenges. The second section considers how these principles are applied largely using interviews with innovative thinkers, manufacturers and brands. The approach provides a clear introduction for readers new to the field, as well as more in-depth information and actionable strategies for those already implementing a sustainable plan.

Textile waste

In the U.S. there are an estimated 25 billion pounds of textile waste generated annually of which just 15 percent is donated or recycled, much of it shipped to African countries. In Uganda, 81 percent of all clothing sold is second hand, according to Dr Andrew Brooks, whose book Clothing Poverty investigates the connection between garment retailers and sub-Saharan poverty.

Recycling alone is clearly not enough. Extended Producer Responsibility (EPR) is one of the initiatives that’s attracting much interest as a way of promoting recycling and end-of-life management. The European Union (EU) has already successfully implemented such schemes for the automotive and packaging industries. Voluntary measures are also not enough, but they do serve an important function with trial initiatives on a small scale, before larger investment is made. Ultimately, legislation is needed at an industry or global level.

Possible processes

Mechanical textile separation has been used with some success for quite a while, but the increase in blends and hybrid textiles, laminates and finishes make this process increasingly difficult. Chemical recycling is now receiving more attention and some funding – in Europe.

dreamstime_xl_50251596-300x200.jpg

Scale is a key issue in the sustained supply of quantity and quality of material ideally achieved locally to prevent increasing the carbon footprint. Solvay’s Move4earth is a European Union funded project that seeks to recycle airbags using a technology that allows them to separate the technical textile from its coating without any significant loss to the material properties.

The VTT Technical Research Centre of Finland have been developing a cellulose dissolution process for recycling cotton that reduces the water footprint by 70 percent and the carbon footprint by up to 50 percent.

In North America, Evrnu use a combination of chemical and mechanical processes to recycle post-consumer cotton garments. The process is designed to prevent off-gassing, reusing solvents and manage the environmental impact in a closed vat system. Importantly for the industry, it works within existing apparel business models.

Recommendations

“Going circular” successfully will require a varied but cohesive approach, and should include these considerations:

  • Whole system solution: The issue has to involve stakeholders at every stage, as textile innovation alone is not enough.
  • Collaboration: This needs to go beyond textile manufacturers and brands to include retailers.
  • Mechanical versus chemical recycling: Partnerships are crucial to achieve scalability and commercial success.
  • Complexity: More research is needed to determine the level of benefit measured against cost of development and implementation.

According to Deloitte’s 2016 Global Manufacturing Competitive Index (GMCI) report the U.S. is set to overtake China as the most competitive manufacturing nation within five years. This brings tremendous opportunity and responsibility for North America to take the lead in developing the principles of a circular economy for the apparel and textile industry. This has to be part of the innovation agenda if it is to be made to work environmentally and economically.

End of Life vs. End of Use: Circular Economy, Getting More From the Clothes That We Wear

Posted on Updated on

by Leslie Johnston

About 13 years ago, I was travelling in a beat-up “bakkie” (or, as we Americans call it, pick-up truck) through a dusty, northern Mozambican town. With a bucket on her head and a face lined from years of hardship, an elderly woman walked slowly down the road, quietly going about her business… while wearing a bright red Ohio State sweatshirt, complete with their mascot, Brutus Buckeye! This sweatshirt, probably discarded at one point in a Salvation Army depot in Ohio, found a new owner in the most unlikely place.

And while one can argue the merits of second-hand clothing imports and their effect on African apparel industry, the following conclusion is clear: When we discard our unwanted clothes, they do not go away.

Rather, the “lucky” ones go on to reuse, after being sorted, categorized, packaged, and shipped, often to faraway lands. This fascinating video shows what happens when these discarded duds arrive in India. “Maybe the water is too expensive to wash them,” says one of the sorters, perplexed by the state of the clothing sent by the West.

But what happens when a piece of clothing is too worn to be, well, worn again? Has it reached its end of life? Judging by the millions of tons of clothing ending up in landfills across the world, one would think so. But it doesn’t have to be.

Clothes that cannot be worn again can be taken apart. The “easy” way is via mechanical fibre recycling, which entails chopping the clothing into small pieces to create new fibre. But this process weakens the fibre, which still needs to be blended with a high proportion of new (or virgin, in industry speak) fibre. And only a small percentage of total clothing actually goes through this process.

But this process doesn’t work if your old t-shirt is made of blended fibres. And we absolutely love those stretchy, fitted t-shirts, which usually have a bit of elastane. In fact, it is estimated that up to 20% of the world’s clothing is made up of a cotton/polyester mix, which means these fibres cannot be “born again” as new fibre for clothing.

But perhaps not for long. Over the past few years, a number of research institutes and innovators (like Worn Again, Evrnu, re:newcell, Saxion University, Mistra Future Fashion, Deakin University, VTT, Aalto University and Tampere University) have been developing chemical recycling processes that can get more life out of those blended t-shirts. I have had the opportunity to speak with some of these guys to learn more about how such technologies can transform the way we use – and reuse – clothes. As Worn Again states, such technologies can create “Abundance for Everyone. Forever.”

In other words, there is no end of life. Only end of use.

But we’re not there yet. The processes for turning blended clothing into new fibre still need perfecting – and scaling – to help the industry eventually eliminate the concept of waste. So, in the meantime, there are some practical things that we – the customers who love stretchy t-shirts – can do.

Love our clothes! We can be inspired by the tips from the Love Your Clothes movement, helping us to think about how we buy, use, and pass on our clothing.
For every new piece of clothing we buy, we can gift or swap an old piece… give it to friend, take it to a charity shop, recycling centre, a “take back” scheme, or take it to swishing party.
Pull a Mark Zuckerberg. We should not be afraid to wear the same thing, every day, to work. Apparently, this also helps us to be more successful in our careers.
Check the labels. Until cotton recycling technologies really take off, a blended t-shirt (e.g. cotton and polyester) is harder to recycle than one that is of a single fibre – whether natural or man-made. Let’s go for that 100%.
Tell our friends…and kids. The clothing we love is taking its toll on our earth. At least 350,000 tons of clothing end up in landfills in the U.K. alone. In the US, just 15% of used clothing and textiles are diverted from landfill and incineration. We all have a role to play. Let’s spread the word and bring back our clothes.

And the more that we do that, the more we can give new life to our old clothes.

Refibra™ – Lenzing’s Initiative to Drive Circular Economy in the Textile World

Posted on Updated on

Lenzing achieved another milestone in its innovation heritage in the textile industry by developing a new fiber based on cotton scraps and wood. Refibra™ is the first cellulose fiber featuring recycled material on a commercial scale and was launched today at Premier Vision textile fair in Paris. The fiber is produced in the TENCEL® production process. TENCEL®, already a market success as an eco-friendly fiber, is now achieving another key milestone by creating from natural resources what is likely the most sustainable fiber. Refibra™ from cotton scraps and wood will further build Lenzing’s reputation as a leader in the field of environmental fiber technology and will push new solutions in the textile industry towards circular economy by recycling production waste.

“For Lenzing, developing circular business models in the fashion industry ensures the decoupling of business growth from pressure on ecological resource consumption. It reduces the need to extract additional virgin resources from nature, and reduces the net impact on ecological resources,” explain Stefan Doboczky, CEO of Lenzing Group, and Robert van de Kerkhof, CCO. Refibra™ – Reborn TENCEL® fiber

The new TENCEL® generation Refibra™ stands for “Reduce, Reuse and Recycle”. “The brand name Refibra™ and the claim ‘Reborn TENCEL® fiber’ illustrate immediately that this new kind of fiber is made of recycled materials promising reduced reliance on natural raw materials. Because Refibra™ is based on the TENCEL® fiber, which has been internationally recognized for its environmentally responsible closed loop production process, Refibra™offers a deep sustainability profile that clearly contributes to circular economy,” van de Kerkhof explains.

Refibra™ with fiber identification Transparency becomes more and more an issue in the textile industry to prove for example material origin. To assure customers that the fiber, made from recycled material, is really in the textiles, Lenzing has developed a new identification system. The system makes it possible to identify the Refibra™ fiber in the finished textile. This guarantees transparency in the overall processing chain.

The Refibra™ fiber itself is part of the global Lenzing Branding Service and the brand is licensed once the textile has undergone a certification process. International partnerships for circular economy “Close cooperation with leading companies who attach particular importance to sustainability is a pre- requisite for a successful market launch,” van de Kerkhof comments. “These pioneering companies offer the possibility of jointly developing concepts that contribute to a more sustainable fashion industry and promote the circular economy in this sector as well.”

For a better planet “TENCEL® itself is an environmentally responsible fiber of botanic origin. With Refibra™, we add to the future of manufacturing and start to reassess waste as resource. The target is to close the loop. We will not stop our innovation before we are there,” van de Kerkhof said. “Lenzing is working for a better planet.”
