PetroSun Announces Formation of PetroSun BioFuels Mexico

PetroSun, Incorporated (PINKSHEETS: PSUD) announced today that the Company has formed PetroSun BioFuels Mexico to establish its algae-to-biofuel operations in the State of Sonora, Mexico. PetroSun BioFuels Mexico will enter into joint venture agreements to develop algae cultivation farms and extraction plants in Sonora and southern Arizona that will produce algal oil, algae biomass products and excess electricity for the Mexican and U.S. markets.

PetroSun BioFuels, the alternative fuels division of PetroSun, has embarked on its three year plan to establish one thousand algae cultivation pods to produce algal oil as feedstock for biofuel refineries. A cultivation pod is a proprietary closed system contained within 640 acres. Based on lower case production projections of 4,000 gallons per acre per year, a single cultivation pod would produce 2,560,000 gallons of algal oil per year. Upon the completion of the one thousand pods, the projected annual lower case production would be 2.56 billion gallons of algal oil per year, which approximates the stated capacity of the existing and planned biodiesel refineries in the United States. Most of the current biodiesel refineries use soy oil as their principal feedstock.
