Pure Algae Denmark (also just known as Pure Algae) is a Danish technology company founded in 2018 and based in Grenaa, Denmark. The company develops modular land-based systems for the cultivation of seaweed, designed for stand-alone operations or integration with RAS (aquaculture and recirculating aquaculture systems). Pure Algae’s technology has been noted for converting nutrients and CO₂ from aquaculture effluents into seaweed biomass, contributing to emission recapture, nutrient recycling and localized production. The company has been highlighted in the European Union Innovation and Maritime programs for its role in supporting circular bioeconomy initiatives and addressing Europe’s reliance on imported seaweed.[1]
History
[edit]Pure Algae was founded in 2018 following scientific research on the cultivation potential of Ulva for environmental and food applications. The company participated in the EIT Food “Seedbed” startup programme at Aarhus University in 2020.[2] By 2025, the company employed around 12 people (7 FTE) and operated multiple cultivation units in Denmark.[3]
Products and technology
[edit]Pure Algae develops modular photobioreactor-based systems for land-based seaweed cultivation. The main platform, VALUEFARM, is designed to capture nitrogen, phosphorus, and CO₂ from aquaculture effluents and convert them into seaweed biomass.[4]
Environmental and operational benefits
[edit]The systems are intended to recycle dissolved nutrients and CO₂, reduce nutrient discharges, and enable stable production independent of season or weather. The approach focuses on specific environmental benefits such as emission utilization, resource efficiency, and eutrophication mitigation.
Recognition and support
[edit]Pure Algae has received recognition through participation in European Union-supported innovation programs. In 2025, the company was profiled by Europe Direct Syddanmark for its EMFF-supported cultivation system using nutrients and CO₂ from fish farms.[5] The company also took part in the EIT Food Seedbed programme at Aarhus University in 2020.[6] In 2020, Pure Algae received the BlueInvest Award from the European Commission’s BlueInvest initiative, which supports innovative start-ups and SMEs in the blue economy sector.[7]
