Plant-Based Color Advancements
Sparxell Scales Sustainable Technologies for Textiles
Debra John — February 4, 2026
Plant-based color innovations are at the center of Sparxell’s efforts to reduce the environmental impact of conventional textile colorants. The University of Cambridge spin-out has secured €4.2 million in pre-Series A funding to support the commercial scaling of biodegradable, plant-derived color solutions that eliminate synthetic dyes, petroleum-based chemicals, and toxic heavy metals.
Sparxell’s patented technology uses cellulose sourced from wood pulp to generate color through light-reflecting physical structures rather than chemical pigments. This process significantly reduces chemical pollution while lowering water and energy consumption compared to traditional dyeing methods. By avoiding plastics and microplastic-forming materials, the technology also contributes to cleaner waterways and healthier ecosystems.
Designed for use across textiles and related industries, Sparxell’s color solutions aim to match the performance of conventional alternatives while improving sustainability across the supply chain.
