The textile industry has long been plagued by environmental concerns, with the production of dyes and textiles contributing to pollution, water waste, and carbon emissions. However, a local start-up at Norwich Research Park is pioneering a groundbreaking new method for dyeing textiles that could dramatically reduce the industry’s ecological footprint.

The Science Behind Colorifix’s Process

Colorifix’s innovative process involves harnessing the natural colors found in organisms such as plants, insects, and animals. Instead of physically extracting the pigment, the company uses the DNA of the organism to identify the genes that produce the color. This genetic information is then used to build a digital code, which is inserted into microbes such as yeast or bacteria. These microbes are fed sugar and nitrogen in a fermenter, much like brewing beer, and are converted into pigment or dye. This process not only reduces the amount of water consumption and electricity usage required for dyeing but also minimizes pollution and carbon emissions.

Benefits of the Eco-Friendly Process

• Reduced water consumption: By using microbes to produce dye, Colorifix’s process eliminates the need for large amounts of water, which can strain local water resources. • Lower electricity usage: The use of microbes and fermentation reduces the energy required for dyeing, resulting in lower electricity bills for manufacturers. • Minimized pollution: The biologically-based process eliminates the need for toxic chemicals, reducing the amount of pollution released into the environment. • Carbon emissions reduction: The process reduces the amount of carbon dioxide emitted during dye production, contributing to a more sustainable fashion industry.

A Growing Partnership with Fashion Brands

Colorifix has established partnerships with several major fashion brands, including H&M, Vollebak, and Pangaia, to provide them with eco-friendly dye solutions. The company currently produces color for mills in Italy, Portugal, Brazil, and India, who supply the dyed fabric to these brands.

Expansion Plans and Recognition

• Scaling up operations: Colorifix aims to expand its operations globally, developing new markets and increasing its production capacity. • Growing client base: The company plans to continue to grow its client base, working with more fashion brands and manufacturers to provide eco-friendly dye solutions. • Commercially available colors: Colorifix hopes to develop more colors that will be commercially available, expanding its portfolio of eco-friendly dye products.

Awards and Recognition

• Sustainable Textile Innovation Award: Colorifix won the prestigious Sustainable Textile Innovation Award at the Drapers Conscious Fashion Awards 2025, recognizing its innovative approach to sustainable textiles. • Enterprise programme: The company has received support from the Anglia Innovation Partnership, which provides enterprise programmes to help researchers and scientists achieve their goals.

The Importance of Norwich as the R&D Base

• Collaboration and communication: The new premises at Norwich Research Park have facilitated improved communication and collaboration among the team, allowing for faster problem-solving and more efficient work. • Access to talent: The campus provides a vast talent pool, making it an ideal location for a company like Colorifix to grow and develop. • Quality of life: Norwich is a wonderful city that offers a great quality of life, providing a comfortable and supportive environment for the team.

Creating Prime Colors and Unlocking New Pigments

• Solar Glow Yellow: Colorifix developed a new color, Solar Glow Yellow, which took three years to create. This milestone marked the beginning of unlocking new pigments and expanding the company’s palette of eco-friendly colors. • Unlocking new pigments: The development of prime colors has enabled Colorifix scientists to start exploring new pigments, opening up new possibilities for the company.

Growth and Recognition in 2024

• Launch of Solar Glow Yellow: Colorifix launched a new color, Solar Glow Yellow, which was a significant milestone in the company’s growth and development. • Rapid growth: The company experienced rapid growth in 2024, with significant increases in its workforce and production capacity. • Brand new premises: Colorifix moved into new premises on the park campus, providing the company with modern facilities and a collaborative work environment.

Quotes from the Team

• “We find colours in nature from organisms like plants, insects, animals or microbes. Then, instead of physically extracting the pigment, we look at the DNA of that organism and identify the codes for the genes that produce the pigment. We then build that DNA code and insert it into microbes, such as yeast or a bacteria, which are fed sugar and nitrogen in a fermenter with water, in the same way you would brew beer. This converts them into pigment or dye.” – Margie Carvalho, Analytics Lead at Colorifix
• “With conventional dye, you’re taking a host of chemicals and heating them into a toxic soup. A lot of those chemicals are irretrievable, so once they’re in the water system, you can’t get them out. We believe that our process for creating dye will help existing brands and manufacturers to move away from chemistry to biology.” – Margie Carvalho, Analytics Lead at Colorifix
• “Since moving in we have noticed a definite improvement in our communication and collaboration. Because we are now all under one roof, things happen quicker and we get to solutions faster. We have five labs and a number of meeting rooms with ample office space to use which makes our work more enjoyable and productive.” – Margie Carvalho, Analytics Lead at Colorifix
• “It has been so rewarding to see the progress that Colorifix has made over the last few years to a point now where it is at the vanguard of having a massive influence on improving the future of the fashion industry by reducing water usage and pollution, all from harnessing the power of nature.” – Roz Bird, CEO of Anglia Innovation Partnership
• “We have an enterprise programme in place to help them achieve that.” – Roz Bird, CEO of Anglia Innovation Partnership
