Sparxell has turned plant cellulose into vivid, biodegradable pigments and foils that rival synthetic dyes in performance. This matters because the £38bn global colourants industry relies on mined metals, petrochemicals, and microplastics. Synthetic dyes emit up to 27 kg CO2e per kilogram, persist for centuries, and cannot be recycled. Many would never pass modern safety standards. Sparxell’s technology, spun out of the University of Cambridge, replaces these with cellulose from renewable feedstocks, cutting carbon footprint by at least 85%. If successful, the project—in partnership with the Manufacturing Technology Centre and Pulpex—will adapt these colourants for paper-based packaging, a £265bn market. Major global brands are already engaged as end-users. The result could be fully sustainable packaging that performs like conventional materials but biodegrades safely, is petrochemical-free, and supports a circular bioeconomy. This would shift a hidden but enormous part of supply chains—the inks, foils, and coatings on nearly every product—away from toxic, non-renewable sources, positioning the UK as a leader in bio-based manufacturing.
View original technical description
**Colourants** make up the dyes, pigments and coatings that are found in almost every part of our homes and daily lives. This massive, £38bn global industry touches on a wide range of products, including cosmetics, textiles, paints, and packaging, but comes at an **extraordinary social and environmental cost**. Produced using a wide range of mined metals, minerals, synthetic microplastics and petrochemical products, colourants are associated with huge greenhouse gas emissions (up to **27 kg CO2e / kg of synthetic dye**), destructive and unethical mining practices, and cause **long-term damage** to the environment, biodiversity and human health. Many colourants are **impossible to recycle**, take hundreds of years to biodegrade, and cannot be sourced renewably. In short, **_many would simply never have been approved for sale if invented today_.** Inspired by the physical principles responsible for some of nature's most vivid colours, and spun out of **world-leading research** at the University of Cambridge, Sparxell has developed the **world's first plant-based, bio-inspired colourants** to rival the performance of today's state-of-the-art. Our **multi-award winning, patent-protected technology** transforms fully renewable natural cellulose feedstocks into a near limitless range of vivid, lustrous and long-lasting pigments and foils. These are **100% safe, biodegradable, petrochemical-free**, and have a carbon footprint at least **85% lower** than synthetic alternatives. The packaging sector's transition to sustainable alternatives offers a massive opportunity for plant-based colourants in a global paper packaging market worth £265bn. In partnership with the UKs **Manufacturing Technology Centre** and **Pulpex** (a world-class innovator in sustainable paper-based packaging), this project will develop new methods for production, and will demonstrate the viable application of fully sustainable, bio-derived Sparxell pigments, foils and inks to a range of sustainable packaging materials. Engagement of major global brands as end-users will accelerate our route-to-market, positioning the UK as a leader in the new circular bioeconomy.
