Urban Rooftop Farms Produce Edible, Nutritious Algae [Pics]

Unused space on a Bangkok skyscraper is transformed into a production site for this super food.

Urban farming and algae are both initiatives that have huge promise for making the most of land and sea where there is very little left to spare. Instead of trying to use one approach over another, sustainable food production company Energaia decided to combine them both on the rooftop of a Bangkok skyscraper.

The roof of a skyscraper serves as an excellent venue for harvesting the edible algae spirulina because of the high temperatures and constant sunlight, both of which help to optimize growing time.

Spirulina is a blue-green plant that offers a complete composition of vitamins and minerals essential for healthy living. Its high protein content can act as a meat substitute, and its additive properties allow it to be used as the main ingredient of pastas and smoothies.


The company is already partnering with hotels, businesses and building owners in Bangkok, to make use of previously unusable rooftop space, and produce huge quantities of the super food. They hope to counter environmental problems that plague the cities and residents of this planet.
