Potential For Biofuel Production From Algae Based Wastewater Treatment In California: Can Algal Biofuels Be Cost-Competitive With Traditional Petroleum Based Diesel?, Amanda Rupiper
Master's Projects and Capstones
Neither the use of algae to clean wastewater, nor the use of photosynthetic organisms to generate biodiesel, are new concepts on their own. By combining these two processes, algal-based wastewater treatment with algal biofuel production, additional benefits can be derived, among which could be a cost-savings. In California the average estimated base production cost per gallon for algal biodiesel is $5.98/gallon. Compared to the adjusted production cost of petroleum-based diesel of $1.53/gallon, biodiesel is not cost-competitive. Coupling wastewater treatment and algal cultivation reduces the net energy use of the two processes separately and, if accounted for, greatly reduces the production …
