The need for increased energy security as well as the concern over greenhouse gas emissions and depletion of fossil fuels requires sustainable alternatives to conventional sources. Biomass is a promising renewable alternative to fossil fuels. It is the world’s fourth largest source of energy, following oil, coal and natural gas, and the raw material for biofuels. Bioethanol as a transportation fuel is attractive as it is more energy efficient than gasoline and produces less emissions. This paper presents an experiment undertaken to obtain bioethanol from sunflower seed shells. Sunflower seed husks represent a waste resulting from the extraction of cooking oil. Such waste has had limited and unimportant use. A rigorous technology for producing bioethanol from such a cheap resource could lead to valuable economic results and would help reduce pollution.
Key words: Bioethanol, sunflower seed shells, sustainability
