High-Performance Sustainable Materials. Naturally.

Across industries, brands are focusing on replacing materials with high embedded CO2 emissions with sustainable, cost-effective alternatives.

Across industries, brands are focusing on replacing materials with high embedded CO2 emissions with sustainable, cost-effective alternatives.

Cellexcel’s molecular level technology accelerates this shift, enhancing cellulose performance to increase the range of viable applications, match real-world needs, reduce CO2 emissions, ensure regulatory compliance and negate forever chemicals and non-recyclable plastics – all in a value enhancing and cost effective manner.

Our patent pending, licensable, and cost-effective technology, Cellexcellent™, integrates directly into existing manufacturing processes, helping you achieve your sustainability goals.

Application

Increasing sustainable solutions for your application

Initially working with the food service industry, we have delivered water/liquid resistance in packaging materials such as fibre-based coffee cups, without any coating or chemicals that prevent repulpability. Cellexcellent™’s strengths can be easily applied across a range of applications and sectors, from automotive and aerospace to construction and logistics.

The technology

How it works

Cellexcellent™ is not a surface coating. Instead, it modifies cellulose at the molecular level through a chemical reaction to enhance its performance characteristics, such as water resistance, fire retardance, and anti-fungal properties. All while retaining recyclability/repulpability and without use of forever chemicals such as PFAS and AKD.

FAQs

Questions, answered.

Everything teams ask before they bring Cellexcel into a material.

What problem does Cellexcel’s technology solve?2026-09-10T05:42:21+00:00

Companies across the globe are seeking to move away from using materials with high levels of CO2 embedded across their lifecycles, or that contain plastics or chemicals, such as PFAS, that present end of life challenges. Industries such as packaging and construction are replacing these materials with more sustainable alternatives, such as those based on cellulose. This enables them to meet their sustainability goals, increase efficiency and comply with circular economy legislation.

Cellexcel’s molecular level technology platform can accelerate this shift, enhancing cellulose performance to increase the range of viable applications, match real-world needs, reduce CO2, and replace toxic chemicals and plastics.

How does the technology work?2026-09-10T05:42:45+00:00

Cellexcel’s patent pending Cellexcellent™ technology works with the cellulose substrate to introduce its property enhancing compound, binding directly to the cellulose molecule. This improves performance characteristics, notably water/liquid resistance, but also may include fire retardance and fungal prevention. As Cellexcellent™ is not a surface coating or spray, existing properties, such as recyclability, strength, and sustainability are not impacted.

Why does water resistance matter for biomaterials such as cellulose?2026-09-10T05:43:09+00:00

Natural, cellulose-based materials are renewable and recyclable, but absorb water easily. This limits the range of applications where they can be used to replace plastic unless they are then coated, often with chemicals that then prevent recycling. Building in durable water resistance without impacting other properties enables cellulose based materials to be used extensively across sectors and applications, replacing embedded materials with high levels of CO2.

How does Cellexcel work with customers and partners?2026-09-10T05:43:33+00:00

Cellexcel licenses its technology platform to partners and customers and has designed Cellexcellent™ to be easily incorporated into customer supply chains. Cellexcel partners with global specialty chemical manufacturers to produce at scale within tightly controlled quality control systems. This enables customer applications and use cases to be rapidly developed and put into global production. Cellexcellent™ is designed to work with existing manufacturing processes, wherever feasible, minimising capital expenditure and operational adjustments.

Is Cellexcellent™ environmentally friendly?2026-09-10T05:43:53+00:00

Cellexcellent™ can be manufactured predominantly from natural, plant based material. It does not require the addition of plastic films, laminates or chemicals in application. This means products remain sustainable, recyclable and compostable.
