Frequently Asked Questions

What does SUN ALGAE Technology do?

SAT designs, engineers and builds commercial scale algae production plants for industrial clients worldwide

How is SUN ALGAE Technology different from all of the other companies that say they are doing the same thing?

The SAT algae plants are using proprietary, highly-advanced  process technologies which are the base for algae productivity rates far above those of competing companies

Where are the Company’s operations located?

Our headquarters for EU and US operations as well as our R&D center (including a demoplant) are located close to Vienna, Austria. Our headquarters for Asian operations is located in Hong Kong.

Where does SAT make all of its algae?

The SAT algae strains are produced in our R&D center in Austria and supplied to our algae plant clients. SAT itself does not operate algae plants of its own.

Who uses SAT’s products? Who are the products aimed at?

Algae based products are algae protein meal (used as animal or fish feed), algae oils for conversion into biodiesel and algae based Omega-3 and Omega-6 oils.

What is algae?

Algae is an informal term for a large, diverse group of eukaryotic organisms that are not necessarily closely related and are thus polyphyletic. Included organisms range from unicellular genera, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga that may grow up to 50 meters in length. Most are aquatic and autotrophic. The largest and most complex marine algae are called seaweeds.

Why algae?

Algae have the highest reproduction rate of any organism on earth. They consume carbon dioxide (CO2) for their growth and can therefore contribute to CO2 mitigation efforts connected to Climate Change. Algae convert CO2 to high value end-products and are therefore one of the few means to achieve CO2 mitigation AND earn a profit

How long does it take to produce algae?

After inoculation an algae culture takes approximately 10 to 14 days until it reproduces stably. After that algae can be harvested on a daily basis

If it’s so valuable, why aren’t individuals scooping algae out of ponds to sell it?

Most of us by talking about algae mean the macroalgae which grow for example in the sea or in ponds and swimming pools. There are macroalgae which are extremely valuable because of their chemical properties. SAT however is specializing in microalgae, an algae form which is totally different from macroalgae.

What can you make with algae?

Algae based products are algae protein meal (used as animal or fish feed), algae oils for conversion into biodiesel and algae based Omega-3 and Omega-6 oils

What are biofuels?

Generally speaking biofuels are fuels which – as opposed to fossil fuels – are made from renewable sources like farm crops, grass, wood and also algae

How does SAT’s algae produce biofuels?

Algae among other substances produced oils which can be converted by different industrial processes into either biodiesel or biokerosene

How are biofuels better than fossil fuels?

Biofuels are made from renewable raw materials which in general have consumed CO2 during their growth. Therefore the use of biofuels does not release additional CO2 into the atmosphere thereby reducing overall CO2 emissions and enable CO2 mitigation.

But I heard that alternative biofuels cost $26 per gallon. Why are they so expensive?

Most of the figures published are speculative. Costs of biofuels are driven by productivity of the relevant process and the investment costs for a production plant. Published figures so far only use low-productivity/ high-investment cost systems since in most cases no precise data are available publicly

What is Omega 3?

Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs). The three types of omega-3 fatty acids involved in human physiology are α-linolenic acid (ALA) (found in plant oils), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Marine algae and phytoplankton are primary sources of omega-3 fatty acids. Omega-3 fatty acids are important for human metabolism. Mammals are unable to synthesize omega-3 fatty acids

What does DHA & EPA mean?

EPA means Eicosapentaenoic acid, DHA means Docosahexaenoic acid. Both fatty acids are part of the Omega-3 family

What is the benefit of consuming Omega-3?

Omega-3 fatty acids, such as DHA, have been shown to promote good health. Research suggests that DHA may:

  • Support a healthy pregnancy
  • Support length of gestation
  • Support visual development and function
  • Support cognitive development and function
  • Support cardiovascular health
  • Support memory

Why would a farmer feed algae-meal to livestock?

The use of algae in the diet for cattle and chicken has shown positive effects for both the animal’s health and the quality of the meat produced by the animals. The reason is that algae are much closer to the metabolism of those animals than other feedstock diets like soybean meal

Why is algae-meal healthier for fish?

Ocean fish consume algae as part of their natural diet, feeding algae to aquaculture fish therefore only mirrors the natural living conditions of fish than any other aquaculture feedstock

What is algae – biomass?

Algae biomass is the name for the algae produced either in the oceans or in dedicated algae production plants. Algae biomass contains both proteins and fatty acids which are made accessible through algae oil extraction processes. After oil extraction has taken place the algae biomass is separated into algae meal (the protein component) and the algae oils
