About Cellexcel™

Cellexcel is a leading technology company dedicated to cost-effectively enhancing the performance of sustainable materials.

Our vision is to support increased global sustainability by enabling the greater use of cellulose materials across applications that were previously locked into the use of plastics and forever chemicals, building circular economies while reducing costs.

Our molecular-level, patent-pending Cellexcellent™ technology enables brands to replace toxic chemicals and high embedded CO2 materials with sustainable alternatives in a wider range of applications, from packaging to automotive and aerospace. This empowers companies to meet their sustainability goals while lowering costs and achieving regulatory compliance, including around the removal of Alkyl Ketene Dimer (AKD) and Per- and polyfluoroalkyl substances (PFAS).

Recognised for innovation and market opportunity

Cellexcel is backed by significant, supportive investors and has been recognised through multiple awards:

HCR Hewitsons Impact55 2025 Winner
Cambridge Tech Week Innovation Alley Award 2024 Winner
Regional winner in 2024 KPMG Tech Innovator Awards
Composites UK Industry Awards 2024 Shortlist
JEC Booster Startup Awards 2024 Finalist

Initial target market – packaging

Our first focus is on enhancing the performance of cellulose-based materials in the packaging sector, by significantly improving properties such as water resistance. This removes the need for AKD and expensive secondary coatings, while ensuring 100% recyclability and repulpability.

A partnership model that scales

We license Cellexcellent™ to partners and customers, with the technology designed to drop-into existing industrial processes and supply chains. Through partnerships with global speciality chemical manufacturers, we deliver Cellexcellent™ at scale, meeting the strictest quality standards.
