Symbiotic EnviroTek Inc. (Symbiotic)(SETI) is a private, for-profit Calgary, Alberta, based firm, focused on commercializing proprietary photobioreactor (PBR) technology to produce biofuel feedstock from microalgae. Symbiotic's modular algae growth technology boasts the adaptability to grow algae in moderate or extreme heat/cold climate condition, and is capable of growing algae phototrophically, heterotrophically, or mixatrophically.

Advanced innovation and a solid understanding of process engineering is what sets Symbiotic apart and provides the company with some outright competitive advantages. For instance, Symbiotic's modular PBR quadruples the yield of all first generation PBR designs over a substantially smaller eco-footprint. Modules are insulated, portable and scalable, capable of being erected anywhere quickly and easily without need for costly enclosures. The modules are easily coupled together to form as large a biofield as needed.

Distinguishing features such as isolatable modules, make general problem solving and routine maintenance like cleaning, easy and quick without need to shut down the entire grow operation. The dual enclosed design reduces water loss due to evaporation and creates a double barrier to reduced chances of cross contamination from within or external invasive predators or competitive strains; it provides a controlled growth environment suitable for growing algae for stringently regulated purposes. An average size biofield has approximately 7M litres of growth media capacity and occupies less than a two acre footprint. Cogeneration capability reduces energy input requirements making energy and carbon balances economically achievable and the rugged steel construction provides long service life expectancy.
