Gary Wood’s Phoenix-area shrimp farm was highly profitable in the 90’s, but after an increase of imports from Asia, Wood went looking for something else to fill his ponds. Now that biodiesel is cost-competitive with its petroleum cousin, algae-farms have been popping up around Arizona and other warm areas. But Wood has an advantage: his shrimp already eat algae, so he knows exactly how to grow it.

“We will harvest the algae in a very similar way we took the buildup from the shrimp ponds,” Wood said. “It is just amazing we are in this position right now. Up until a couple of years ago, we didn’t realize we’d done so much of this research.”
