The local everywhere solution.


Many of today’s complex challenges demand a new way of doing things, a sustainable way of working with nature
instead of against it to achieve economic and social progress. At SabrTech, we realize that if a solution
is going to make a difference at a global scale, it must be revolutionary.

Our RiverBoxTM is just such a solution.

By addressing the exploding demand for algal biomass in markets like aquaculture, fuel, neturaceutical, chemical and personal care, our innovative technology will revolutionize algae production.

It is a local everywhere revolution.

The RiverBoxTM is deployable for on-site algae production anywhere in the world as a modular unit,
in a greenhouse, outdoors exposed to the sun, or in a brick-and-mortar facility.

The RiverBoxTM, a world's first


Global challenges. Sustainable growth.


Traditional methods to supply algal biomass for industries such as aquaculture and fuel face common challenges:

High costs due to low production yield, significant CapEx, high energy consumption, and large footprint

Species limitations due to geographic locations where algae is produced

Price volatility due to competition with human food chain supply

Supply restrictions due to long distance transportation

Significant environmental impacts due to open systems

Lack of scalability

Our target markets



Faced with rapid feed stock decline and structural environmental issues, the aquaculture industry has a significant and fast growing requirement for waste remediation and sustainable feed alternatives. Algal biomass represents a key opportunity as a replacement or additive for aquaculture feed.



Algae are capable of producing a wide range of beneficial compounds and nutrients ideal for the nutraceutical industry. With a rapidly growing global population and significant challenges to food production due to climate change and pollution, producers are challenged to find truly sustainable sources of nutraceutical ingredients.




Algae requires a smaller footprint, utilizes waste CO2 as a feedstock and does not compete with the food industry. It is an ideal feedstock for the global biofuel market. With SabrTech's flexible, low-cost and rapidly deployable platform, this sector represents a significant long term opportunity.

Personal care


Natural beauty and well-being ought to come from natural sources. To that end, our algal biomass production systems can produce a wide variety of natural oils for personal care products from skin care to vitamins and antioxidants - all with the health (and beauty) of the flora and fauna at heart.

Passionate and experienced

SabrTech’s team is comprised of 13 experienced and committed individuals with a wide variety of expertise covering engineering, finance, marketing, biology, genetics, and ecology.

With collaborations and partnerships across Canada, the USA, Europe and Asia (including DHI-Aquaculture, APAC region), we are bringing together a solid group of industry experts and state-of-the-art technology to make SabrTech's vision come true.

“With the right partners, SabrTech will become the global leader in local everywhere algal biomass production.”
