I
n Bangladesh, the demand of fossil fuel has been consistently increasing with the development of its industrial and agriculture
sectors. The annual demand of petroleum products in Bangladesh is met primarily by refining imported crude oils from overseas.
To meet the future energy demand and to save foreign exchange, it is essential to look for domestically produced renewable fuel
sources. Bioethanol from biomass and biodiesel frommicroalgae could be potential alternate fuels for Bangladesh. Bioethanol, which
is generally obtained from the conversion of carbon-based feedstock, is a quasi-renewable energy source. Although Bangladesh
does not commercially produce bioethanol till date, there are few initiatives at the private sector in this regard, and therefore, it
is important to understand the fuel properties of bioethanol. This study analyzes different fuel properties, namely, specific gravity
& API gravity, viscosity, Reid vapor pressure, calorific value, ASTM color, ASTM distillation, copper strip corrosion and water
sedimentation, of bioethanol and 5 and 10 percent bioethanol blended with petrol and octane. To make biofuel production from
microalgae economically viable and sustainable, it is important to identify microalgae strains with high lipid content and to find
an optimized mass culture technique for local condition. This study presents the growth kinetics of microalga
Chlorella vulgaris
grown in Bangladesh, in the parameters of cell count, optical density and dry cell weight cultured in 4 different media, namely
CH, BB (Bold’s Basal), MLA and CHU (modified). The growth curves obtained from algal growth in all the media were compared
with lipid productivity. The extracted lipid was trans-esterified to produce biodiesel and the algal biomass left after lipid extraction
was analyzed to quantify protein and other nutrients. This study will be highly useful, providing the baseline properties of locally
produced bioethanol and biodiesel as potential alternate fuels for Bangladesh.
Biography
