Specialists in the extraction of active substances from microalgae, KeyNatura has a fully integrated value chain. That means everything from the culturing of our microalgae in tank-based photobioreactors, to the extraction process and product formulation is all carefully managed in-house. In this way we minimize potential contamination risks and ensure the delivery of stable, high-active and high-quality astaxanthin with a long shelf life.
Our microalgae are cultured using Iceland’s clean air and water and renewable power to support efficient photosynthesis and growth. The algae feedstock is extracted using cutting-edge technology as part of a controlled, cost-effective and innovative process.
KeyNatura has extensive expertise in aqua and microalgae-culture, food and pharma technologies, and aquatic pathobiology. This knowledge, combined with a determination to unlock the potential of microalgae for food supplements and feeds, is driving the development of technological solutions suited to the challenges of mass production.
In scaling up production of its breakthrough “tank technology”, KeyNatura is helping to solve a number of issues:
The new technology enhances productivity by controlling factors that are important for fast growth and by integrating ‘pest management’, which reduces losses to just 5% (from rates experienced with other technologies of 30-50%).
It delivers a higher return on capital compared with traditional “tubular reactors”.
Installation costs for tanks are much lower and operational costs are significantly reduced (less electricity used due to LED lights and easier handling and cleaning).
It offers more sustainable access to a recognized, sustainable source of unpolluted and nutritious food and feed components.
KeyNatura’s “tank technology” offers cleaner, more efficient production than the alternative open-pond and tubular systems. Inside each meticulously engineered tank is a photo bioreactor (PBR), which secures a harvest of microalgae in any type of climate and ensures stable productivity levels. Suitable for inland-farming, it requires only a fraction of the land space needed by other traditional technologies, and significantly less water and energy for its efficient operation.
