| Abstract: | Purpose Though the development of biofuel has attracted numerous studies for quantifying potential water demand applying life cycle
thinking, the impacts of biofuel water consumption still remain unknown. In this study, we aimed to quantify ecological impact
associated with corn-based bioethanol water consumption in Minnesota in responding to different refinery expansion scenarios
by applying a life cycle impact assessment method. |
