Canadian cement factory producing algae biofuels from carbon emissions

In Canada, St Marys Cement is investing in an algae-based biodiesel system that will be implemented by Pond Biofuels to help reduce the facility’s greenhouse gas emissions. For every kilogram of algae produced, 2kg of CO2 are mitigated. Though the Pond system only uses a small amount of the 540,000 metric tons of CO2 produced every year, the 25,000 liter pilot plant at the facility can grow up to six generations of algae per day thanks to LED technology.
