Est-Agar, the only factory of its kind in the world, has been located in Saaremaa since 1966. The factory processes hundreds of metric tons of Furcellaria lumbricalis, a red algae that is most abundant in the coastal waters of Saaremaa. Since last fall, a unique experimental farm has been operating in the coastal waters of Saaremaa, trying to cultivate the floating form of the red algae.
