  PetroSun, Inc. (PINKSHEETS: PSUD) announced
today that PetroSun BioFuels and the Town of Gilbert, Arizona have executed
an agreement to commence an algae-to-biofuels wastewater pilot program at

The purpose of the program is to evaluate the feasibility of the utilization of wastewater as a source of nutrients and water for the cultivation of algae and its subsequent processing into feedstock for the production of biodiesel and other products. The Town of Gilbert will be offered all biodiesel produced from this pilot program at the actual cost of production and processing during the term of the program.

"The Town of Gilbert has a stated interest in expanding the sources for renewable and sustainable energy for the benefit of its citizens," stated Gordon LeBlanc, Jr., PetroSun CEO. "This wastewater pilot program is an important step in the commercialization of the algae industry."
