Carbon Dioxide Sequestration by Microalgae: Biorefinery Approach for Clean Energy and Environment
Environmental implications and climate change due to greenhouse gas emissions have raised concerns about the sequestration of CO2. Photosynthetic microalgae have shown excellent potential as a precursor for renewable biofuels, commercial bioproducts, and animal or aquaculture feed. Utilization of CO2 for cultivation of microalgae is a sustainable and environmentally friendly approach for biological CO2 sequestration. There are engineering constraints and challenges to make the overall process economically feasible which needs to be addressed. Integrating this biological CO2 sequestration approach in a microalgal biorefinery with utilization of wastewater is a green approach for clean energy and environment.
