“Three times a week, Patsakorn Thaveeuchukorn harvests the green algae in the barrels. ‘The algae is growing so fast, normally the doubling time is around 24 hours,’ said Patsakorn, whose employer EnerGaia uses Bangkok’s rooftops to grow spirulina. The empty space on top of Bangkok’s many skyscrapers provide suitable growing conditions for spirulina as the constant high temperatures and sunlight are ideal breeding conditions. The algae also helps combat carbon dioxide levels through photosynthesis, its champions say, and growing it in cities means it can reach consumers the same day it is harvested. The company says it is the only producer of fresh spirulina in the world.”
