Title of the presentation: Microalgae As Synergistic Feed stock For Environmental Pollution And Third Generation Biofuels

Abstract: 

 

 

Air pollution abatement, economic growth, stability and the ongoing depletion of oil reserves are all major drivers for the development of economically rational and renewable energy technology platforms. Therefore, there are vigorous research initiatives aimed at developing renewable and potentially carbon neutral solid, liquid and gaseous biofuels as alternative energy resources. Based on current knowledge and technology projections, the third generation biofuels specially derived from microalgae are considered as a technically viable alternative energy resource that devoid the major drawbacks associated with the both first and second generation biofuels. Microalgae are simple photosynthetic microorganism with simple growing requirements (light, sugars, CO2, N, P, and K) that can produce lipids, proteins and carbohydrates in large amounts over short periods of time. Among all the biomass feedstocks for the third generation biofuels, microalgae biomass has emerged as the special kind of feedstockdue to its high  lipid  accumulation capacity during the growth (60-80% of biomass), high photosynthetic efficiency to produce biomass and higher growth rates with higher lipid productivity. This study reviewed the technologies underpinning microalgae-to-biodiesel systems, focusing on the biomass production through open system (raceway pond) and closed system (photobioreactor), harvesting, extraction of oil and conversion technologies. Besides this, a synergistic coupling of microalgae propagation with carbon sequestration and wastewater treatment potential for mitigation of environmental impacts associated with energy conversion and utilization. It was found that, whereas there are outstanding issues related to photosynthetic efficiencies and biomass output, microalgae-derived biofuels could progressively substitute a significant proportion of the fossil fuels required to meet the growing energy demand. Thus it is imperative to develop a suitable technology package for the mass cultivation, harvesting and processing of microalgae and examine its techno-economic feasibility for production of bio-diesel and other value added products.
