The ELUCENT project has successfully moved bio-based pigments from laboratory research to industrial readiness, delivering the world’s first plastic-free, toxin-free and fully biodegradable reflective pigment.
Funded by Innovate U.K., the 18-month collaboration brought together three partners: Sparxell, the University of Cambridge spin-out, with a plant-based, bioinspired color technology; PANGAIA, the global materials science company applying innovations to fashion; and the Manufacturing Technology Centre (MTC), U.K.’s independent research and technology organization.
Together, they have demonstrated how science, design and engineering can deliver scalable, sustainable alternatives to conventional pigment systems. By combining Sparxell’s pioneering cellulose-based color platform, PANGAIA’s expertise in design application, and the MTC’s ability to scale processes for industry, the project shows how interdisciplinary collaboration can reduce environmental impact without compromising creativity or performance.
Sparxell led the technology development. The company’s patented process uses cellulose, the world’s most abundant biopolymer, to create vibrant color particles inspired by nature. Unlike conventional pigments, these are free from plastics and toxins and are fully biodegradable.
As design partner, PANGAIA tested the pigments on textiles in collaboration with London-based Orto Print Studio, producing printed fabric prototypes and testing durability. This step bridges lab innovation with real-world applications of these bio-based colorants in fashion and beyond.
The Manufacturing Technology Centre (MTC) ensured the pigments could be scaled beyond the lab, building custom production systems and validating performance at an industrial level.
The completion of this project marks a step change for sustainable color. Sparxell has successfully transitioned from university research to a technically validated platform, demonstrating significant improvements in pigment formulation, liquid dispersion, and film casting performance.
A commercial launch is projected for 2026.
Founded in 2023 by University of Cambridge scientists, Sparxell is a color platform technology company that developed what it says is the first 100 percent plant-based, high-performance pigment technology using cellulose. Sparxell works with partners across industries providing innovative, nature-inspired solutions that support the transition to a circular and environmentally responsible manufacturing ecosystem.
PANGAIA is a materials science and global collective of scientists, technologists, and designers, working together to design an earth positive business model
