About

Globally, mussel farming produces hundreds of thousands of tonnes of adhesive protein fibres (byssus) that are currently landfilled or used as biomass. At the same time, the built environment depends on mineral wool, foams and PET felts, while cosmetics rely on microplastics and petrochemical powders, all carbon intensive, poorly recyclable and often toxic. 

Seastex addresses the combined challenge of unmanaged aquaculture waste and the lack of scalable, circular, nature-based materials for acoustic comfort and “clean beauty”.

Seastex has developed the first industrial process capable of cleaning and processing heavily contaminated byssus from long-line and raft-cultured mussels. Over a controlled cycle, our proprietary purification methods and technologies remove shells, grit and organics while transforming the byssus’s natural adhesive plaques into a binder. This creates a pure protein, self-binding, flame-retardant fibre that can be moulded into acoustic panels or converted into cosmetic-grade powders. 

The result: a single circular platform that upgrades an unused marine textile waste stream into zero-VOC, low-carbon, recyclable, biodegradable materials for architecture and cosmetics, directly serving climate, circularity and zero-pollution goals.
