Grouse Fibres is an advanced materials company converting dairy side-streams into high-performance protein fibres and circular bioproducts.
Using protein science and wet-spinning technology, we transform non-food milk proteins into biodegradable fibre formats with tunable properties that value the functionality of the protein backbone. This creates a versatile materials platform for agriculture, horticulture, controlled-release systems, biodegradable fibre structures, specialist textiles and advanced bio-based products.
Our first commercial applications include functional additives for peat-free growing media, where growers need reliable materials that support yield, plug strength and crop consistency. The wider opportunity is to turn low-value dairy residues into scalable, functional materials for markets where performance, circularity and sustainability are increasingly important.
