Suzanne Lee wants to live in a sustainable material world. Built with biology. Not oil.
Ruben Baart, Editor-in-Chief at Next Nature Network.
Biotechnology is nearly as old as humanity itself. The food you eat and the pets you love? You can thank our ancestors for kickstarting the agricultural revolution, using artificial selection for crops, livestock, and other domesticated animals. And our modern civilization would hardly be imaginable without the fermentation processes that gave us beer, wine, and cheese.
Biotechnology is spreading into every aspect of our lives—from our everyday products to our materials. In fact, Biotechnology already plays an important role in the textile industry. Enzymes are used routinely to wash and bleach textiles, to give jeans a denim look or to prevent wool from shrinking. Now, a new wave of biotechnology could take this a step further.
In a not-so-distant future, our clothes will be made and dyed by ‘living factories’ (such as mycelium, bacteria, yeast and algae), ditching many of the chemical processes that make the textile industry one of the most polluting industries in the world.
Many players around the world are already disrupting the textile industry with biofabrication. On the forefront of this material revolution is fashion designer turned biofabrication pioneer Suzanne Lee, who is nurturing a global community of innovators growing materials at Biofabricate.
Lee coined the term ‘biocouture’ in 2004 to describe her pioneering research growing clothing using living organisms. In 2007 Lee published the groundbreaking book, ‘Fashioning The Future: Tomorrow’s Wardrobe’, where, for the first time, new technologies for fashion and textiles were captured and mapped out. It remains a key text for designers, scientists and engineers wanting to glimpse the future of wearable technology.
In 2014 she became chief creative officer at Modern Meadow, a New York-based biotech startup growing collagen to manufacture animal-free bioleather materials. In that same year Lee launched the Biofabricate Summit in New York (and as of 2019 in London), bringing together artists, scientists, and designers to share projects and discuss the growing concept of biology-as-technology.
Today, as the founder and CEO of Biofabricate, Lee has established a platform for collaboration in design and biology to grow the future of sustainable materials for consumer products.
We caught up with innovator-in-chief Suzanne Lee and discussed evolving world’s first biocreative consultancy, what it means to bring new biomaterials, biodesign and biofabrication to fashion, beauty, sport and luxury, and how to take biomaterials from the lab to the market. So buckle up, and enjoy the ride.
Biomimicry, Biobased, Biomaterials, Biofabrication; many of these terms are now finding their way into mainstream communication (which I guess is a good thing) yet, it simultaneously creates a set of buzz-word terminology, which may undermine or, even pass by, the urgency of developing such innovative methods and materials today. How do you relate to this?
The increasing use of the prefix ‘bio’ we find is actually creating confusion in many sectors both on the industry side and on the consumer side. These words are not widely understood and, worse, frequently incorrectly applied.
It’s a daily challenge in our consulting work at Biofabricate. We find it concerning because decision-makers are taking action based upon these misunderstandings. This is especially true where people are looking to biology for sustainable solutions or alternatives to petrochemical ingredients and materials.
Not all ‘bio’ is the same! Biomimcry for example, simply means inspired by nature – the actual execution of a biomimetic principle is often achieved using non-renewable, man-made polymers.
At Biofabricate we urge people to question exactly what someone means when they use a particular ‘bio’ term and also what assumptions they are making based on their understanding. Some widely promoted biobased solutions can be environmentally worse than the plastics they aim to replace.
Not all biomaterials are biofabricated, and not all biofabricated materials are made in the same way etc. To fully understand the pro’s and con’s, we need to first understand what someone means by ‘bio-x’, along with its associated production system and life cycle, before we can make any judgement about whether it is beneficial or not.
We are currently working with some industry partners to create guidelines that, for biofabricated materials at least, will provide clear definitions and set out acceptable targets that benefit both customers and the planet.
Many people do not yet understand the breadth in scope of the field of biodesign, its complexities and time to market – instead they just want to know when it might become a reality, when can they buy it?
Since we’ve been discussing terms let’s consider the term biodesign for a minute. Arguably humans have been designing biology for millenia via selective breeding. The recent widespread adoption of the term biodesign means different things according to whom you speak.
Biomedical researchers would say they coined the term to describe health technologies for the human body, synthetic biologists are biodesigners harnessing gene-editing tools such as CRISPR for industrial biotech purposes, and in the creative arena we have artists and designers applying the term to experiments with living organisms for example growing dyes and materials from bacteria, yeast, algae and fungi cultures.
The innovations possible when we design and manufacture with biology are incredible. Early innovation stories are quickly picked up by the media with the effect that suddenly everyone thinks the world is about to be transformed overnight - that we’ll all be living in houses or clothes that we’ve grown! If only it were that simple. What this does is set false expectations about where technologies are today and which can truly scale for impact. The reality is that the field of consumer biotech, products that we can all go into our local stores to purchase, is still nascent.
We’re at the dawn of a new age where we can biodesign and biofabricate. But we all need to be patient.
Yes, if you live in Japan and have $1300 to spend on a ski jacket you might be lucky enough to get your hands on one of the first biofabricated ‘Brewed ProteinTM’, jackets from biotech firm Spiber and their brand partner Goldwin. Or if you’re an Omega luxury customer you could purchase a spider-silk NATO watch strap made by the German biotech AmSILK.
These biodesigned fibers are the first of their kind but they are not yet accessible to most of us. As with many new technology innovations, they often start out very expensive in highly limited supply and, as the technology scales over a period of time, costs come down and availability increases. So while we’re starting to see a few products in the hands of consumers, we’re really at the start of a long journey into biofabrication that will be measured in decades, not months.
What is the biggest barrier at the moment in making biofabrication more ‘mainstream’? Is mainstream even a goal? And if so, how to deal with potential consumers bias in relation to working with living materials as a raw material?
Again, there are multiple technologies making up the field of biofabrication, so there’s no single answer to that question. In general, biofabricated products require many years of R&D, followed by pilots and finally commercial scale-up which can take tens, if not hundreds of millions of dollars. So more investment coming into the field is one requirement. As early investors start to see returns from successfully launched consumer products, many more will want in and so the market for these new technologies will grow.
All the entrepreneurs in our network are seeking to ultimately achieve scale on an order that can service the needs of mass markets. That’s the way to have true impact on a planetary level and for your shareholders.
As for there being any reticence on the part of consumers for biofabricated products, that will come down to manufacturers and brands being 100% transparent about every aspect of their technology. From the feedstock origin used to supply an organism with nutrients, to a product’s end of life.
There is still much consumer ignorance around how our existing products are made. Industrial biotech has been biodesigning living organisms for many decades to manufacture everything from the enzymes in our washing powder to the flavorings in our food. We need to provide people with all the facts so they can make smart decisions. The GMO debate becomes more nuanced when you weigh the pro’s and con’s of animal-derived or oil-derived with biotech-derived.
When introducing innovation, we at Next Nature often think about the story of the 'horseless carriage'. A concept that originates from the first cars; they looked like horse carriages but without the horses. It illustrates how every innovation must pass through a first stage in which the new effect is secured by the old, making the ‘new' accessible through the known. In your previous TED talk ‘Grow your own clothes’ (2011) you mention how garments were decomposing while wearing them. Now, nine years later, we wonder. How does one maintain a biofabricated jacket? Can it feed from the wearer’s skin? Are these garments wearable mini-labs? Do such garments come with ‘best before’ dates; how to educate future generations?
I’m glad you asked me that, I wish I had a dollar for every time I’m asked it. But it’s the wrong question. That TED moment has haunted me for the last decade!
The decomposing comment was a light-hearted remark made after my talk. We actually already had multiple ways of waterproofing it back then. The real challenge for the Biocouture project, wasn’t one of fixing biodegradability, it was one of economics.

Cellulose, being the most abundant natural polymer on the planet, is incredibly cheap to come by. In the world of textiles, cellulose fibres like cotton are not just priced at the commodity level but in some cases receive government subsidies.
To make a convincing case for fermentation of cellulose you either need to find some spectacular functional benefits or significant environmental efficiencies. If I can give one piece of advice to all the budding biodesigners/biofabricators out there it would be this: do the maths first.
Innovation is all about timing. The BiocoutureTM project which started in 2003 and ended in 2013 was far too early.
Fifteen years later, multiple startups around the world are trying to do the exact same thing and are finding it much easier to raise money, find partners, etc.
The fashion world has come a long way in just the last couple of years. Sustainability is now an imperative and some of the world’s premier luxury and sport brands are now the early investors in biofabrication startups which is fantastic for the next generation of entrepreneurs.
As for fabrics feeding a wearer’s skin, I do believe we will eventually get to this point but we’re a long way from that reality. If you speak to the founders of any biofabricated material startup they will tell you just how hard it is to compete with the already demanding expectations of brands who have become accustomed to the very cheap, hi-performance benefits of synthetic fibers or the amazing properties of animal-derived materials like leather and silk. Delivering function, aesthetics AND price at volume is enough of a challenge for most.
The biofabricated jackets you can buy today require the same kind of care as the garments you already wear and love. There’s nothing freakish about them.
Garments that have a symbiotic relationship with the wearer are, for now at least, likely to remain in the realm of art projects. Before we fixate on the implications of living textiles, I believe we’ll first experience many more products in the personal care space that work in harmony with our skin microbiome.
The success of companies like Mother Dirt is testament to that. Look at what’s happening in the probiotic food and beauty space and you’ll see that eventually living textiles will be a natural progression with easier acceptance than you might expect.
Lycra is a nice example of a novel material from the 1950s that took a decade of R&D and marketing before it could go into (mass)production. What can we learn from this and how can we apply this knowledge to biofabrication?
I use the Lycra example all the time. It was actually ten years of R&D, a further 3 years and millions of dollars to get it to market, and then a further 60 year innovation journey. Remember too that Lycra was created by DuPont with all the resources they have.
I often find there are ridiculous expectations placed on startups that are really just a bunch of passionate grad students with some exciting research. Investors and brands want unrealistic outcomes in laughable timelines. Having a compelling prototype in the lab is the easy bit. Repeating it, improving it, scaling it, that’s where the hard work lies.
The wonder of nature is just how easy it looks. Behind the elegance of natural systems is unimaginable complexity.
Take the spider, it’s one thing to produce a silk protein in a microbial cell (no mean feat) but the spider’s real magic is its spinning mechanism. Being able to effortlessly spin multiple protein types achieving variable functionality in real-time by modifying a living spinneret – THAT is miraculous, and the best human minds are still scratching their heads at how to accurately replicate such a device.
Creating performance fibres from synthetic polymers requires amazing chemistry and materials science. Creating performance fibers from synthesized natural polymers adds biology to the mix. We need to be kind to our innovators – give them time! We still have a long way to go on this exciting biofabrication journey.
You speak of “using microbes to grow a similar cellulose material in a lab in a few days in contrast to growing a plant, like cotton, in a field over several months.” Can you share your thoughts on speeding up fabrication processes in relation to the current trend of ‘slow fashion’?
What I was trying to illustrate is the speed and efficiencies of fermentation compared with traditional crops or animal agriculture. The most compelling reason for designing organisms to produce some of our most valuable ingredients and materials is environmental. We cannot continue to put the burden on our planet.
We need to radically rethink production systems to more efficiently use our land, water, energy and chemistries. This is about driving towards a lighter carbon footprint or, ideally, towards regenerative practices.
But let’s be under no illusion. We can totally change the way we manufacture materials but the elephant in the room remains the same: human consumption is beyond that which the planet can sustain.
No matter which production system we adopt we also need to address how much we buy. I’d like to think that the recent pandemic will give people pause to reconsider what is important in life and perhaps change where they place value. Having lived without fast fashion for x months, do they still need it to feel fulfilled? That’s about changing psychology, which is its own unique challenge.
