Alginor ASA

What Alginor ASA does

Alginor ASA is a Norwegian marine biotech company founded in 2014 in Haugesund, Norway, that develops a vertically integrated value chain for the commercial harvesting and biorefining of Laminaria hyperborea (brown kelp) sourced from Norwegian waters. The company's proprietary platform consists of two components: Hypomar, an upstream harvesting and separation technology that eliminates formaldehyde by separating kelp into leaf and stipe fractions immediately after harvest; and AORTA, a downstream biorefining platform using parallel and consecutive fractionation, extraction, and purification processes that achieves approximately 100% biomass utilization versus the industry standard of 15-20%. This produces six product categories from a single raw material: alginates, fucoidans, cellulose, seaweed extracts, kelp fibers, and kelp powders.

The company serves B2B customers across pharmaceutical (cGMP-grade APIs and medical devices), nutraceutical and food, personal care, animal feed, and industrial applications. Operations are conducted through wholly-owned subsidiaries: Hypomar AS (harvesting via the Hypomar Ocean 1 vessel delivered in May 2024), Alginor Biorefinery AS (biorefining), and Oewa AS (R&D at the Deep Tech Centre in Haugesund). The flagship F3 commercial biorefinery at Avaldsnes is under construction with total CapEx estimated at NOK 820-870 million and targeted to produce 5,000+ tonnes of high-value ingredients annually.

The company is pre-revenue, with commercial sales pending biorefinery commissioning. It has raised over NOK 1 billion since inception through a combination of EU and Norwegian public grants (Horizon 2020, EIC, Research Council of Norway, Innovation Norway) and private equity rounds led by strategic investor Borregaard AS (approximately 41% ownership), Must Invest AS (approximately 21%), and Hatteland Group (approximately 12%). The company had over 50 employees and 616 shareholders as of 2026, and is preparing for a future public listing based on its Oslo office establishment.

Core offering

Alginor ASA harvests and biorefines Laminaria hyperborea (brown kelp) from Norwegian waters to produce high-purity kelp-based ingredients, including alginates, fucoidans, cellulose, seaweed extracts, kelp fibers, and kelp powders. Using proprietary zero-formaldehyde separation and biorefining technology, the company supplies pharmaceutical-grade (cGMP) and food-grade ingredients to pharmaceutical, medical device, nutraceutical, personal care, food, and animal feed companies globally. The business operates as a vertically integrated value chain covering harvesting through wholly-owned subsidiary Hypomar AS, processing through Alginor Biorefinery AS, and R&D through Oewa AS.

Product overview

Alginor ASA is a Norwegian marine biotech company developing a fully integrated value chain for commercial harvesting and biorefining of Laminaria hyperborea (brown kelp) for production of kelp-based ingredients. The company operates through wholly-owned subsidiaries: Hypomar AS (harvesting vessel operations), Alginor Biorefinery AS (biorefinery), and Oewa AS (laboratory/R&D). The product portfolio consists of six categories derived from a single raw material source: alginates, fucoidans, cellulose, seaweed extracts, kelp fibres, and kelp powders. These ingredients serve three market segments: medical (pharmaceutical ingredients and medical devices produced under cGMP), personal care, and health & nutrition (food-grade). The AORTA biorefining platform and Hypomar upstream technology enable total utilisation of the biomass (100%) without toxic chemicals like formaldehyde.
