Microalgae offer great potential as a third-generation biofuel feedstock, especially when grown on wastewater, as they have the dual application for wastewater treatment and as a biomass feedstock for biofuel production. The potential for growth on wastewater centrate was evaluated for forty microalgae strains from fresh (11), brackish (11), or saltwater (18) genera. Generally, Cited by: 4. 4 Natural Resource Use. Fuel production from fossil and biological feedstocks is resource intensive, and algal biofuels require resource inputs in the form of water, energy, land, and biofuels have been produced at small scale, sufficient to prove that there are a number of possible production pathways.
production • Utilizing a -relatively cheap N source like urea ( gL 1) to supplement post-chlorinated wastewater effluent can certainly improve the techno-economics of large scale microalgal growth for biodiesel production • PAM fluorometry further justified the efficacy and suitability of utilizing. The current obstacle for microalgal biodiesel development lies in its economics, because until now there has been no commercial large scale production. There are two main reasons: microalgal biodiesel production process is chemical and energy intensive; and a high portion of microalgal biomass remains as residuals after biodiesel production.

Department of Energy. Fuels from Biomass Systems Branch.; University of California, Berkeley. Sanitary Engineering Research Laboratory.]. The study considered four algae biofuel production scenarios, viz.
production under nitrogen fertilizer rich and starved conditions and with oil extraction from wet and dry raceway ponds varied from g m-2 d -1 (in the nitrogen starved case) to g m-2 d -1 (in the nitrogen rich case).
Of the four algae biofuel production scenarios. An engineering-economic feasibility analysis indicates that the production of microalgal biomass for chemicals and fuels may be feasible at favorable locations if a simple bioflocculation-settling harvesting process can be developed. A series of experiments was carried out with small-scale (12 sq m) ponds using sewage as the substrate.
Production of microalgal biomass in raceway ponds as a feedstock for biodiesel has been extensively studied during the US Department of Energy's Aquatic Species Program. Although raceways are low-cost algal cultivation systems, they have a low biomass productivity compared with by: Algal-Based Renewable Energy for Nevada.

This work models the production of microalgal biomass using freshwater algae grown using synthetic fertilizers and CO 2 /flue gas from an industrial power plant.
The objective of this work is to compare different technological routes for producing dried algal biomass to be used for as a feedstock for conversion to liquid transportation fuel(s). Currently, biodiesel production from microalgal biomass has drawn an immense importance with the potential to exclude high-quality agricultural land use and food safe-keeping issues.
Moreover, microalgae can grow in seawater or wastewater and microalgal oil can exceed 50–60% (dry cell weight) as compared with some best agricultural oil crops Cited by: This work models the production of microalgal biomass using freshwater algae grown using synthetic fertilizers and CO 2 /flue gas from an industrial power plant.

Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane.
When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil. Several companies and government agencies are funding. Raceway ponds are widely used in commercial production of algal biomass.
They are effective and inexpensive, but suffer from a relatively low productivity and vagaries of weather.

Commercial production of intracellular microalgal metabolites requires the following: (1) large-scale monoseptic production of the appropriate microalgal biomass; (2) recovery of the biomass from a relatively dilute broth; (3) extraction of the metabolite from the biomass; and (4) purification of the crude extract.
