ABSTRACT

 

The utilization of non-renewable fossil fuels as the main source of energy has raised many environmental concerns such as seawater pollution from oil spills. Biofuel has become popular as countries strive to reduce environmental impacts of carbon emissions generated from petroleum diesel burning. Even though the combustion emission from biofuel has been proven to be more environmental friendly compared with fossil fuel, the result may be different based on the whole biofuel life cycle. This paper discusses two types of biofuel that are widely used globally, which are bioethanol and biodiesel. The sustainability of biofuels is discussed based on their advantages and disadvantages of the production and utilization of biofuels on Life Cycle Assessment perspective.
