Cellexcel

Enabling the adoption of biomaterials in demanding environments and applications to reduce embedded carbon emissions.

About Us

Cellexcel’s Cellexcellent™ technology works at a molecular level, going far beyond simple surface treatments or sealants. By delivering, and attaching, unique compounds to the cellulose molecule itself, essential performance properties, such as water resistance, can be measurably enhanced.

This ensures that, when biomaterials are employed in reinforcing a composite component, the part can be formed, by machining and drilling, without the fear of moisture ingress at the machined edges while abating moisture ingress in areas susceptible to surface damage.

Through its patented environmentally friendly treatment, which is free from petrochemicals or forever chemicals. Our Cellexcellent™ technology aims to replace conventional methods such as coatings that exhibit edge defects once cut. It is compatible with all cellulosic fibres.

Our mission is to enable biomaterials to be employed across a wide range of industries, so they can meet embedded sustainability goals, benefiting us all. Cellexcellent™, a unique, patented technology has been developed to bring about the molecular modification of biomaterials, to enable the enhancement of essential performance properties, starting with water resistance. Through this molecular modification, biomaterials become highly suitable for a vast array of new applications with low or zero embedded emissions.

Since successfully closing our initial funding round, we are working with industry partners from multiple sectors to commercialise and develop Cellexcellent™. This will enable us to target the global multi-billion dollar biocomposite market, licensing our technology to relevant partners across the value chain.
