This paper projects a positive outcome for large­scale algal bioenergy production when wastewater treatment is the primary goal. Such a view arises partly from a recent change in emphasis in wastewater treatment technology from simply oxidizing the organic matter in the waste (i.e. removing the biological oxygen demand) to removing the nutrients, specifically nitrogen and phosphorus, which are the root cause of eutrophication of inland waterways and coastal zones. A growing need for nutrient removal...
