Why Algae?

We grow algae in photo bioreactors (PBR) rather than in open ponds, because they provide a clean controlled environment. These are large clear tubes linked together that contain water and a specific strain of algae. A CO2 delivery system is attached to the tubes. Once the algae is seeded, it is fed CO2 from the cement plant, which in combination with sunlight causes algae to grow. Our high efficiency photo bioreactors accelerate algae growth, increasing the rate of CO2 absorption.

Creating Biomass:
From the PBRs, algae is centrifuged to remove most of the water. Ultrasound is used to separate the oils from the solid. This process yields (i) “green crude” which will be further refined to make biodiesel, and (ii) “biomass” which our customers can burn as a low carbon fuel, substantially reducing their coal intake.

Producing Biodiesel:
The conversion of “green crude” into biodiesel is called transesterification. Our refineries employ a new biodiesel catalytic reactor which uses methanol, pressure, heat and a tri-metal catalyst to convert green crude into raw biodiesel. The methanol is removed from the raw biodiesel and is final filtered to produce pure raw B100 biodiesel.

This fuel is superior to its petroleum counterpart because it is biodegradable, performs better in diesel engines, ignites more easily, helps promote longer engine life because it has better lubrication qualities, produces 40% less pollution when burned, and is actually cheaper than petroleum diesel. Our customers can use this biodiesel to completely offset their fuel requirement for their trucking and heavy equipment fleets. We can help them sell the surplus on the open market.
