Could this be the leather of the future?
CNN, May 2024
Start-up Modern Synthesis is creating new materials by working with living organisms – bacteria. The aim is to create low-carbon alternatives to traditional fabrics, curbing emissions and plastic pollution. “For the first time, we’re able to offer the aesthetic and performance of the materials that we use everyday but without the plastic and without the animal. I can’t stress how hard that is.”
Technology
Reinventing materials
The result: a revolutionary class of nonwoven materials which can be tuned to displace a spectrum of textiles, from plastic films to leathers.
Microcraft
Redefining textile craft, from the nanoscale. Inspiring the senses with the exceptional strength, refined beauty and tactility of nanocellulose, this new class of materials unlocks new design possibilities, bringing life to a new era of luxury.
Natural technicals
The next generation of performance, by nature – plastic-free technical textiles are here, offering a sleek, highly adaptable alternative to synthetic coated materials with the intrinsic circularity of cellulosics.
Impact
Reimagining systems
Our evolving biotechnology process addresses 5 related challenges: GHG emissions, waste, land use, plastic pollution and animal welfare.
Our technology drives systems changes across
Animal welfare
Unlike leathers and exotic skins, our materials don’t necessitate animal slaughter, and unlike ‘vegan leathers,’ they don’t rely on harmful additives
Greenhouse gas emissions
Research suggests that our GHG emissions could be significantly lower than leather and petrochemical-based textiles
Food waste
Since our microbes can digest any kind of agricultural sugar feedstocks, we minimise waste and enable a decentralised closed loop system
Land use
Bioreactors take up much less space than farms or chemical plants, radically reducing the amount of land needed to produce a meter of material
Plastic pollution
Unlike synthetic textiles, our 100% plastic-free materials can be designed to safely biodegrade, reducing ecosystem degradation and microplastic shedding

Team
Reinventing collaboration
As a team of biologists, chemists, designers, engineers, storytellers, robots and microbes, our team knows that magic happens when disparate disciplines, perspectives and ideas collide.
Founders
Our Founders: Dr. Ben Reeve (CTO) and Jen Keane (CEO)
The first seeds of Modern Synthesis’ future were planted during our Co-founder Jen’s Central Saint Martins MA project, This is Grown. Jen’s Previous work at adidas and Nike inspired her to re-envision the product design process by growing the upper of an athletic shoe with only bacterial nanocellulose and one continuous yarn. While working on This Is Grown, she collaborated closely with scientists from Imperial College London, including our Co-founder Ben, who discovered and sequenced the strain of bacteria that we employ to produce our novel biomaterials today.
With a PhD in bioengineering and previous experiences as the founding CTO of Puraffinity, Ben’s technology vision proved to be the perfect complement to Jen’s design ambitions. Their collaboration was both a response to our ongoing plastic crisis and an attempt to prove the profound design and performance possibilities of new biomaterial technologies. Now at the helm of Modern Synthesis, they remain united by the idea that sustainability, technology, creativity, and beauty can – and should – go hand in hand.

Growing a biomaterial future with Jen Keane
WGSN, April 2023
Jen Keane joins WGSN on their Create Tomorrow podcast to discuss what’s next for biomaterials and what brands can do to work collaboratively with startups in this field. “It’s a replacement for leather, but it doesn’t feel exactly like leather and it doesn’t behave exactly like leather. These materials are really new and can help us design products differently and we need to approach them that way.”
These textiles were grown by bacteria
Fast Company, April 2023
Modern Synthesis has developed a novel way to create textiles from a microbe, and the resulting material could be sold to brands as a replacement for synthetic fabrics. “It’s naturally transparent, and it almost looks like a nylon or technical synthetic fabric,” Jen Keane says. “But the feel is much more natural. And it’s adaptable in terms of its hand feel.” It can be more flexible, for example, or thicker…
