AlgenAir Inc. has partnered with Pittsburgh International Airport’s (PIT) innovation hub, xBridge to evaluate its aerium Living Technology system, which uses algae to improve indoor air quality.
The system has been installed in PIT’s Baggage Claim Arrivals area and is the first commercial-size model of AlgenAir’s aerium Living Technology.
This use of algae aims to improve health and environmental issues in public facilities.
It works by pumping air through the tubes, where the algae filter carbon dioxide and impurities out while producing oxygen that is released back into the indoor atmosphere to improve the air quality.
“The aerium Living Technology will enable building owners to improve indoor air quality without sacrificing energy efficiency.”
The 10 vertical tubes in the aerium are 8 feet tall and hold more than 100 gallons of the algae spirulina, which has the photosynthetic capacity of more than 5,000 plants.
Fresh spirulina is green but will eventually turn blue as it absorbs more and more carbon dioxide. Once it has reached maximum capacity, fresh algae will be added and the spent biomass will be used as fertiliser around the airport campus.
After a three-month pilot period, PIT and xBridge will evaluate the results and determine if the aerium should be used permanently at the airport.
“The xBridge is representative of Pittsburgh’s thriving tech economy. We’re excited to partner with AlgenAir on the proof-of-concept for aerium Living Technology as we work to increase clean energy and decarbonisation options.”
