US-based start-up @AirBuildinc has developed an algae-based system that can filter out pollutants and contaminants from wastewater, at the same time as absorbing excess carbon. Once the algae has done its work, AirBuild turns it into biochar, a soil-improving agent that locks absorbed carbon into the ground for centuries. Here, AirBuild’s CEO David Gory explains how the process works. AirBuild is a winner of UpLink’s Yes San Francisco Urban Sustainability Challenge.
