Revolutionising Sustainable Materials with Protein-Based Fibres
Creating high-performance, sustainable fibres from waste protein feedstocks to reduce peat dependency and advance eco-friendly growing solutions.
Our Mission
Materials for Life
Grouse Fibre Limited is dedicated to creating a future where sustainable materials drive progress. Our mission is to replace environmentally taxing resources with high-performance fibres made from waste proteins, providing solutions that serve both industry and the planet.
Proteins offer unmatched potential as a sustainable material toolkit due to their unique structural properties, nutrient content, and versatility. Our innovative use of protein fibres creates an eco-friendly alternative to conventional materials, setting a new standard for sustainable development.
Untapping the Potential of Proteins
Why Proteins?
Proteins offer unmatched potential as a sustainable material toolkit due to their unique structural properties, nutrient content, and versatility. Our innovative use of protein fibres creates an eco-friendly alternative to conventional materials, setting a new standard for sustainable development.
Structural Uniqueness: Proteins form resilient, adaptable fibres suitable for high-performance applications.
Nutrient-Rich Composition: Protein-based fibres naturally add nutrients, ideal for supporting plant growth and soil health.
Adaptability: Proteins are highly adaptable for polymerisation, forming robust, flexible materials that can meet various industry needs.
Our innovative use of protein fibres creates an eco-friendly alternative to conventional materials.
The Challenge with Current Peat-Free Solutions
Existing peat-free growing mediums—such as bark and coir—do not fully meet the technical requirements for growers aiming to transition from peat. These cellulose-based materials lack the high nitrogen content, absorption capability, and adaptability essential for robust, sustainable growth.
Introducing Protein-Based Fibres
Grouse Fibre’s protein fibres are engineered to fill this gap, providing a high-nitrogen, highly absorbent alternative made from waste feedstock. Scaled production of our fibres will support the horticulture industry with an efficient, environmentally responsible replacement for peat-based materials.
Our protein-based fibres could save approximately 9.7 million tonnes of CO₂ emissions by replacing peat in horticulture
