Life Cycle Assessment of Biodiesel Production from Microalgae in Thailand: Energy Efficiency and Global Warming Impact Reduction

Life Cycle Assessment of Biodiesel Production from Microalgae in Thailand: Energy Efficiency and Global Warming Impact Reduction

In this study, a life cycle assessment (LCA) technique based on ISO 14040 series was performed to evaluate biodiesel production from freshwater microalgae Scenedesmus armatus in terms of energy efficiency (Net Energy Ratio or NER) and environmental impact (Global Warming Potential or GWP). The syste...
