Micro Algae

Micro algae are one of the most important bio-resources of the future and use sunlight for energy. Micro algae are found everywhere in nature, can have enormous growth rates and can be a renewable source of valuable biomass.

This algal biomass is not only a renewable source of fertilizer and bio-energy, but also of many different compounds for high value bio-products, for use in; food, health products, cosmetics, feed for livestock and fish as well as ingredients for medicine and industrial application, thereby contributing to the tendency towards natural solutions. Last but not least, micro algae can be used to reclaim lost nutrients from e.g. process water, water from flue gas scrubbing, bilge water from livestock ventilation, drainage and waste water and can in this way contribute to optimizing resources and reducing emissions in a production.

Over the last many years, we have built up laboratories and knowledge regarding testing, characterisation, upscaling and optimisation of growth conditions for microalgae. Our upscaling facilities cover microalgae production from single cell to continual production in 750L photo bio-reactors, permitting us to advise and help you with moving microalgae from the research scale to pilot production and harvest.

If your company is looking at the possibilities involved in establishing a micro algae production, DTI can help you! You can consult us regarding commercial algae production and bio-remediation and we have a variety of facilities available.

How can Danish Technological Institute help you?

Analysis and test of a specific algae cultivation and remediation potential

  • Characterization of optimal growth conditions for microalgae
  • Demonstration of algae production upscaling to pilot size in 750 L photo-bioreactor and open algae pond /raceway cultivation
  • Microalgae propagation for commercial production
  • Advice on commercial algae production, hereunder:
    Design of cultivation systems
    Nutrition levels, pH, CO2, O2, temperature, light requirements
    Start-up and propagation for own operation
    Harvest and stable production management
    Hygiene, contamination and disinfection
    Screening of side-streams for nutrient content
    Analysis and test of algal cultivation and remediation potentials
    Microalgae cultivation system design
    Start up and scale up for actual operation
    Harvest and management to stable production

 We have hands-on experience with microalgal remediation of:

  • Degasified pig slurry and raw slurry
  • Bilge water from biological and acid-based air purification
  • Urban waste water
