India, being a highly fossil fuel dependent country has to explore the possibility of several renewable sources for the production of biodiesel and its co-products to satisfy its environmental targets. In this connection, a prospective life cycle assessments of two algal systems were studied. The LCA impact results conclude that algal system producing biodiesel, animal feed, and succinic acid could be beneficial to the environment compared to that algae system that produces biodiesel and animal feed. Thus algae system could be a potential alternative or additional renewable system to mitigate environmental impact in South India.
