PetroSun, Incorporated announced last week that the field testing of the cultivation of algae for biodiesel production has now progressed to the final stage prior to the construction of a commercial cultivation facility. This final stage will consist of producing adequate algae paste to test the output and economics of several biodiesel refinery manufacturers now under consideration by Algae Biofuels, a wholly owned subsidiary of PetroSun. The company will own and operate the production and refinery facilities. 

Algae BioFuels is considering sites in Arizona, New Mexico, California, Louisiana and Michigan for its initial commercial cultivation of algae feedstock in the United States. Australia and China are the leading candidates for production and refinery operations in the foreign marketplace.

The company has modified its initial plan to locate its biodiesel refinery in Arizona to include other areas of the United States that prove to be commercially viable in the cultivation process. "Should the cultivation process prove to be successful outside of the U.S. Sunbelt, Algae BioFuels model is to locate production and refinery sites near major cities and truck routes to reduce the cost of biodiesel in those areas," said Gordon LeBlanc, Jr., CEO of PetroSun. "We view this as an opportunity to produce a renewable energy product that will assist in providing a healthier planet for future generations."
