The Biomimicry Institute has awarded the 2023 Ray of Hope Prize® to Sparxell, a UK-based startup creating the next generation of colors and effects with vibrant, metal-like pigments, all from plant-based cellulose.
By utilizing cellulose in pigment creation, Sparxell is showing how nature can color our world without the harmful environmental and societal effects of mined and synthetic minerals.
Making Biodegradable Pigments from Cellulose Nanocrystals
As the 2023 Ray of Hope Prize recipient, Sparxell will receive $100,000 in recognition of their groundbreaking, nature-inspired work.
Conventional substances used to make our cosmetics, fabrics, paints, and packaging bright and colorful often include metal or oil-derived ingredients. For example, the most common pigment, titanium dioxide, causes a white coloration and is used in products from toothpaste to paper. Titanium dioxide has recently been recognized as a carcinogen and banned from food and pharmaceutical products in the EU. Furthermore, many pigments are mined in areas with high incident rates of human rights abuses, and where water is scarce. There are some bio-derived alternatives, but none have been able to compete at cost, until Sparxell.
Sparxell has developed the first environmentally sustainable, non-toxic pigments, glitters, sequins, and films. Inspired by structural color found in nature, such as that of a butterfly wing or peacock feather, their patented manufacturing technique transforms cellulose nanocrystals (CNCs) into uniformly reflective, highly dispersible particles with state-of-the-art performance. The pigments are a fully biodegradable, easier to source alternative with an unlimited range of vibrant colors. Because they can tune the structural color pigments to reflect specific bands of light, their pigments even enable new types of color. All this is possible while adhering to the recent EU regulations on microplastics like glitter.
“
We are proud to support Sparxell as the 2023 recipient of the Ray of Hope Prize for their work to eliminate toxic chemicals from colorants,” said Dr. Sarah McInerney, Ray of Hope program manager at the Biomimicry Institute. “
The incredible Sparxell team has developed a truly unique performance pigment from plant-based cellulose and in the process has set a new eco standard for a diversity of industries. As a platform technology, the potential environmental and social impact of this solution is huge. We couldn’t be more excited to support them on their journey.”
That journey began at the University of Cambridge’s Bio Inspired Photonics Lab (UK), where Sparxell’s founders replicated the exact nanostructure that gives the fruit of Pollia condensata (marble berry) its vibrant blue color using cellulose and nothing else. Now, their growing team is poised to transform industries as diverse as cosmetics, paints, fabrics, automobile coatings, and packaging, with sustainable vibrant colorants representing a $65B market overall.
Runner-up Recognition Goes for Sustainable Bioelectric Process
This year’s runner-up recognition goes to Canada-based Anodyne Chemistries, which uses nature’s catalysts, enzymes, to solve the chemical industry’s reliance on fossil fuels, replacing high temperature petrochemistry with a sustainable bioelectric process. Currently, the chemical industry is responsible for about 5% of global CO
2 emissions. Transforming this sector is a key to moving away from a fossil-fuel-based economy and to achieving net-zero targets.
Anodyne Chemistries has developed a method of bioelectrical manufacturing that can compete against petrochemical economics, overcome the limitations of biological fermentation, and outperform electrochemistry, which are the main industrial processes and emergent technologies for chemical production, respectively. This technology could decarbonize the chemical industry while applying principles of Green Chemistry to create a new generation of climate positive chemicals.
“
I’m thrilled by the quality of all of the finalists of the Ray of Hope Prize this year, in particular Sparxell and Anodyne Chemistries,” said John Lanier, Executive Director of the Ray C. Anderson Foundation and selection committee member. “
These businesses are in completely different sectors, but each has a solid business plan, a compelling biomimicry story, and most importantly, an authentic social and environmental ethos. Anodyne’s enzymes offer an exciting pathway to low carbon chemicals, while Sparxell has unlocked cellulose as a source of pigments for nearly any color. With nature as their teachers, they are primed to positively disrupt their industries.”
