Cellexcel is a materials technology company providing a patented, sustainable molecular modification process that enhances the water resistance of biomaterials, enabling their use in demanding industrial applications to reduce carbon emissions.
Cellexcel Ltd is a UK-based manufacturing company and University of East Anglia spinout that develops patented technology for the chemical modification of biomaterials. Their proprietary Cellexcellent technology works at a molecular level to attach unique compounds directly to cellulose molecules, which enhances essential performance properties such as water resistance. This treatment is environmentally friendly, free from petrochemicals or forever chemicals, and is designed as a sustainable alternative to conventional surface coatings and sealants that often fail when cut or damaged. The process is compatible with all cellulosic fibres and aims to enable the use of natural fibre composites in demanding applications, such as automotive, aerospace, construction, and electronics.
By facilitating the adoption of these modified biomaterials, Cellexcel helps manufacturers reduce their embedded carbon emissions and meet sustainability goals. The company operates as a licensing partner across the materials value chain, working with composite manufacturers, fabric treatment suppliers, and original equipment manufacturers. Through their technology, they provide a path to replace conventional, less sustainable materials like fiberglass, carbon fibre, and plastic in external applications. Supported by various innovation grants and investment funds, Cellexcel is actively commercializing its technology to address global market demand for high-performance, low-carbon bio-composite materials.
