Life Cycle Assessment of Bioethanol from Microalgae

M. Kohl, D. Iribarren, F. Petrakopoulou & J. Dufour
Liquid biofuels, such as biodiesel and bioethanol, are expected to play a leading role in achieving a more secure, reliable and sustainable energy sector. Microalgae are seen as a possible feedstock for future bioenergy systems, due to their high productivity and potentially high oil or carbohydrate content. In the present study, the life-cycle environmental performance of a hypothetical “microalgae-to-ethanol” system was evaluated. The system includes cultivation of the carbohydrate-rich microalgal strain Chlorella vulgaris in open...
