'EnerGaia' is a Thai startup that is growing edible algae on the roof of the Hotel Novotel Bangkok. Urban farming is quickly becoming a popular way for consumers to grow their own produce and now the same techniques are being used to grow spirulina.
EnerGaia's facilities are located on the roof of the Hotel Novotel in downtown Bangkok. The rooftop is outfitted with rows of white barrels that use carbon dioxide as an inorganic carbon source to grow edible algae. After harvesting the spirulina, the algae is sent to a facility that dries and packs it for consumers. Over the course of a year, the rooftop farm can produce between 300-500kg of spirulina for stores and retailers all over Thailand.
With a system that uses minimal space and resources, the innovative urban farm demonstrates that spirulina can be grown virtually anywhere.
