­­­­­­­­­­­­­­­­­­­­­­Alginor ASA seeks towards a sustainable and resource efficient future based on seaweed treasures from beyond the Arctic Circle. We focus on total utilization of seaweeds for production of unique, pure and formulated products in a multifunctional biorefinery. Through safe, eco-friendly and efficient operations, Alginor sets the standard for tomorrow’s innovative solutions and technologies.


Alginor ASA was established 24th March 2014 to commercialize knowhow and technology through the construction of an integrated Biorefinery for seaweeds.

Seaweeds are among the world’s largest untapped resource. Norway’s seaweed forest constitutes 80 % of the coastal biomass with a standing stock estimated to 50 million tons. However, in order to utilize seaweeds effectively it is necessary to use a technology which exploits the entire biomass – a biorefinery.

Alginor plans to start up the first biorefinery in Norway focusing on total (i.e. 100 %) utilization and resource efficient processing of seaweeds to pure and formula-specific products for use in food, feed, pharma, agri, chemicals and materials. The biorefinery will be in the form of a Demonstration unit with a tentative production capacity of 5,000 tons of seaweed per year. Further, Alginor plans a new expansion to a full-scale industrial Biorefinery with an annual production capacity of 50,000 tons of seaweed per year.

AORTA technology

Alginor’s Ocean Refining Total utilizing Application (AORTA) technology is paving the way for an incredibly clean, cost effective and resource efficient method of biomarine processing, that will transform the existing value chain and spur Blue Growth globally. AORTA is the key to a future circular bio-economy based on total utilization of seaweeds with zero emissions to water, air and sea.

AORTA’s advantages compared to state-of-the-art alginate-processes are:

  1. Maximum exploitation of seaweeds
  2. Broad product portfolio
  3. Unique products
  4. Eliminating the use of preservatives and organic solvents
  5. Zero pollution
  6. Reduced production costs
  7. Low volume/high price products

AORTA can offer long-term supply of highly requested products from sustainable seaweeds. The AORTA technology provides customers with large volumes of each product and helps cover high market demands from industrial customers.

Product portfolio

AORTA will facilitate a novel and unique Product Portfolio from seaweeds. The products of the Portfolio will be in powder form in order to meet the highest quality and market requirements of industrial customers and market participants.

All the components from seaweed will be converted into ultra-pure and formula specific end-products of highest quality, produced in a multifunctional processing unit with reuse of energy and zero emission to air, sea and environment. The supply of ultra-pure and fine-powdered products will enable new value chains of end-products to consumers on a global basis.
