About us 2018-07-09T14:41:30+00:00
With over 10 years of hands-on experience with Nannochloropsis Gaditana, and many other species, we offer a solid basis of experience

Freeze-dried algae powder from our R&D facility has been sold all over the world as a food supplement. We now leave the algae production to our GemTube customers.

Our own production allowed us to validate and further improve our technology. These valuable years of practical experience resulted in the development of the unique and patented Wavywind™ and Bubblebrush™, two-phase tubular photobioreactor.

As basis of the foodchain microalgae are of great impact on

  • Food
  • Feed

  • Ingredients

  • Pigments & Anti-oxidants

That’s why we call them gems.

We’ve experienced most things that others are exploring now

A few years later we started a R&D collaboration with Georg Fischer, a global leader in industrial piping systems, to further improve and commercialise the technology.

The combination of our unique process and Georg Fischer’s innovative materials resulted in the market introduction of the GemTube™ photobioreactor. Top quality made affordable without compromises. GemTube™ PBRs are available from 20 to 18.000 liters.

We believe that algae have a bright future. To meet the demand there’s need for affordable, easy to use, stable and robust cultivation systems. That’s what we do and why we do it.

At our company and greenhouse facilities in The Hague we designed, developed and tested our innovations. Now at our current location in Rotterdam the development and design continues. We install GemTubes™ all over the world. Our continuous technological progress and worldwide field experience enables maximal support of your production process.

We still cultivate microalgae for test purposes.

We can test if your algae thrive in our system.
Because it is important to know what a GemTube can do for you!
