Aqualia's All-gas project researchers Miled Morad (L), 33, and Ignacio de Godos, 30, check the tanks at a waste-water treatment plant in Chiclana de la Frontera, near Cadiz, southern Spain June 6, 2013. The Spanish resort town with sprawling golf courses and tree-lined beaches has added another green site to its attractions: the world's first plant to convert sewage into clean energy. The facility in Chiclana de la Frontera on the southwest tip of Spain uses wastewater and sunlight to produce algae-based biofuel as part of a 12 million euro project to pursue alternative energies and reduce reliance on foreign oil. While industries such as breweries or paper mills have produced biogas from wastewater for their own energy needs, All-gas is the first to grow algae from sewage in a systematic way to produce a net export of bioenergy, including vehicle biofuel.
