Canadian Cement Plant Becomes First to Capture CO2 in Algae

A Canadian company called Pond Biofuels is capturing CO2 emissions from a cement plant in algae — algae the company ultimately plans on using to make biofuel.


It’s no secret that the process of manufacturing cement is both energy intensive and dirty. Global cement production alone emits roughly five percent of greenhouse gas emissions annually, both as a byproduct of limestone decarbonation (60%) and from the burning of fossil fuels in the cement kilns (40%). And as the demand for concrete-intensive infrastructure soars in developing countries like China and India, global emissions from cement plants—and other industrial sources—will continue to rise.

The algae will be grown at a facility adjacent to the stacks, harvested, dried using industrial waste heat, from the cement plant and then used along with the fossil fuels that are currently used in its cement kilns. The company says they hope to demonstrate the scalability of the industrial pilot project and to show that it can be employed on virtually any industrial stack.

"To resolve the problem you have to have an industrial solution, not a laboratory solution," Terry Graham, chairman of Toronto start-up Pond Biofuels told the Toronto Star. "In a laboratory you can control everything. But you can’t do that in the field," added Graham.

good for Canada

another country does it first. playing catch up is hard.
