Welcome to the World of PROTEUS
Join us as we revolutionise sustainability with the world’s first industrial-scale biorefinery, transforming Europe’s brown macroalgae into eco-friendly solutions and building a circular bioeconomy for a greener future.
The PROTEUS project, supported by the Circular Bio-based Joint Undertaking and its members, aims to build the world’s first fully integrated industrial scale biorefinery dedicated to unlocking the full potential of Europe’s brown macroalgae. By developing chemical-free harvesting and extraction techniques, PROTEUS seeks to transform 100% of this renewable resource into products for food, animal feed, personal care, and industrial applications. Bringing together eleven leading European organisations, the project leverages advanced processes and technologies to support the transition to a circular bioeconomy, creating new opportunities within the bio-based industry.

The latest field evidence from Norway’s Institute of Marine Research shows that although kelp biomass in southern Nordland generally returns to previous levels five years after harvest, the epiphyte-rich community and associated biodiversity takes closer to eight years to recover, contrasting with current practices across most of Norway. The 2025 publication adds important field-scale stock and extraction estimates, clarifies how kelp respond in the first year after harvest, and outlines method
Project partner Essity has published a feature on its contribution to PROTEUS. In the press release, the company presents its work on bio-based super absorbents derived from sustainably harvested brown macroalgae. The feature explains how Essity is assessing raw materials from Laminaria hyperborea for products such as baby diapers, feminine care and incontinence products. It also
PROTEUS partners met in Haugesund in December 2025 for two focused days for their first project review and fourth meeting that combined technical review with field visits. The programme included an inspection of the Hypomar harvesting vessel and a walkthrough of Alginor’s biorefinery facilities. The meetings aligned achievements, clarified next
In the face of growing climate change related challenges and resource scarcity, the European Union has placed the bioeconomy at the heart of its transition toward a sustainable, circular future. Central to this vision is the valorisation of marine biomass as a renewable, low-impact resource. The PROTEUS project is one
Alginor is a fully integrated B2B biomarine ingredients company developing sustainable, high-value ingredients from brown macroalgae for uses in the medical, personal care, food, feed and agricultural industries. The company is developing an integrated value chain consisting of two primary businesses, including offshore harvesting of wild-caught raw materials through its own operated vessels, and valorisation of ingredients through biorefining. Alginor’s vision is to expand the availability and use of sustainably sourced ingredients based on Laminaria hyperborea – a self-renewable resource growing in abundance in Norway and Europe – through utilisation of all components in the biomass without using any harmful chemicals.
Alginor plays a key role in the PROTEUS project as the project coordinator, overseeing the flagship biorefinery development from 2024 to 2028. Alginor is responsible for key aspects, including the sustainable harvesting of Laminaria hyperborea, biorefinery process innovations, and the commercialization of kelp-based product ingredients. Their focus is on converting bio-based side streams into valuable products, with the goal of minimizing waste and enhancing resource utilization. Through their leadership in various work packages, Alginor ensures the project’s alignment with industrial, environmental, and regulatory standards.
Borregaard operates one of the world’s most advanced and sustainable biorefineries. By using natural, renewable raw materials, we produce advanced and environmentally friendly biochemicals that can replace oil-based products.
Utilising the different components of wood, we produce biopolymers, speciality cellulose, biovanillin, cellulose fibrils and bioethanol for a variety of applications in sectors such as agriculture and aquaculture, construction, pharmaceuticals and cosmetics, foodstuffs, batteries and biofuels. We employ 1100 man-years in plants and sales offices in 13 countries throughout Europe, Asia and the Americas.
Strong innovation efforts is one of Borregaard’s strategic priorities. Long-standing research and development have resulted in solutions that respond to important long-term global challenges. Our sustainable products and solutions can play an important role in addressing some of the world’s greatest challenges: Population growth and climate change.
Borregaard will investigate fibrillation of cellulose derived from L.hyperborea to make microfibrillated cellulose (MFC) for use as a replacement for synthetic additives e.g., coatings, adhesives, surfactants and detergents.
Objective: To achieve a TRL of 7-8 in kelp-based ingredients into bio-based materials for industry applications.
Key performance targets include achieving an energy-efficient fibrillation process, maintaining or improving MFC quality compared to wood-based MFC, ensuring microbiological stability, increasing dry matter content, introducing unique MFC properties, and exceeding application performance achieved with wood-based MFC in selected applications.
