Using Algae to anaerobic digestion

In a session at the 2013 Greenbuild in Philadelphia, Taimur Burki, Global Green Building Program Manager for Intel Corporation, and Joshua Wray, Graduate Research Assistant (PhD) at Arizona State University, discussed the possibility of using algae as an industrial emissions control strategy.

The session picked apart the results of an experiment between ASU and Intel to analyze algae’s impact on the industrial sector. Wray, a self-professed algae farmer, has been involved in many bioremediation projects in the past that involved capturing nutrients from waste streams, but, in this case, the algae was intended to draw carbon and nitrogen from flue gases.

After identifying the many alternate uses of algae—biofuels, pharmaceuticals, even cookies—researchers found that some strains are very adaptable. Picking and choosing the best strains for this was incredibly important. Essentially, only specific strands of algae will feed on carbon dioxide and help reduce emissions.

The desert is used as a perfect test site for many reasons. These dry places offer a lot of sun (which is key to photosynthesis), heat, access to wastewater and non-arable land. Not to mention, many world-renowned algae scientists live there.
