Gilbert wastewater plant grows algae for biodiesel experiment
The Arizona Republic reports that Gilbert, Arizona’s wastewater treatment plant has begun growing algae on purpose as part of a biodiesel experiment with PetroSun. The experiment will run for the next three months or so and will include evaluating its growth rate, species, and oil content. Also under study is the cost of growing and harvesting the algae as well as the cost of extracting the oil. If the experiment succeeds, Gilbert will get all the biodiesel produced from the pilot program at cost for use in town vehicles.
