Primafuel produces algae in what Iyer describes as a “low-input” process. Instead of starting with a fat or sugar that takes energy to produce, it grows algae in shallow, open ponds. The algae are “fed” sunlight, carbon dioxide and small amounts of “green” fertilizer (less than is required for growing crops).
According to Iyer, Primafuel’s fertilizers are made from waste biomass, including grass clippings and woody residue. The biomass is converted into nitrogen-bearing ammonia, which is high in nitrogen. Since ammonia is usually produced from natural gas and coal, the process is a big improvement on business as usual. “We think it can help reduce the carbon intensity of all agriculture,” Iyer said.
The fact that algae can make the desert bloom helps explain Primafuel’s partnership with the Jacob Blaustein Institutes for Desert Research at Israel’s Ben-Gurion University. “Algae research was once considered the fringe of the fringe, but finally the world has come to see its incredible potential,” says Professor Sammy Boussiba of the Microalgal Biotechnology Laboratory at the Institutes.
