Phycologic harnesses algae to purify indoor air

Sydney start up Phycologic has launched its novel Seatree which harnesses the photosynthetic power of algae to purify indoor air. Founded by engineers and marine scientists Zac Duryea and Jack Vitnell (pictured), the company worked with University of Technology Sydney’s Deep Green Biotech Hub to develop the algae-filled Seatree. Marine algae is responsible for 70 percent of the air we breathe, with it now set to appear in offices to improve the air quality within buildings. Duryea said: “Phycologic is harnessing this incredible photosynthetic power by creating biological air filtration systems to improve the air quality within your buildings. Indoor air is generally 2-5 times more polluted than outdoor air and we’re here to help this issue.”
