Airbuild

Airbuild has devised a system to filter polluted water using microalgae pods that strip out pollutants like PFAS, E. coli. and also capture carbon. The company is constructing a demonstration facility in Green River, Utah, and cofounders David Gory and John Bucur expect each pod to remove 500 tons of CO₂ and filter 2 million gallons of water annually. The duo has raised $1 million to date.
