BIODIESEL FROM ALGAE

BIODIESEL FROM ALGAE

Abstract:

    Increased environmental awareness and depletion of resources are driving industry to develop alternative fuels from renewable resources that are environmentally more acceptable. Esters of fatty acids (biodiesel), derived from the transesterification of oils from algae, gives 98% conversion, have properties similar to components of petroleum-based diesel fuel.
    Algae produce 60% of their body weight in the form of triacylglycerols (natural oil). By consuming CO2 algae productivity increases, which has positive, effect on ozone layer, minimizes green house effect and increases the scope of exploration of marine life.
     Biodiesel is biodegradable and non-toxic fluid. Cost of biodiesel has been a major factor for slowing its commercialization. To overcome this high cost, transesterification of fats and oil into biodiesel gives valuable co-products such as glycerol and methanol, which are extensively used, in industry and as consumer products.
