The environmental impacts caused by greenhouse gas emissions are a global concern, and for this reason, the search for ways to reduce these emissions has become a critical factor in our society. Although carbon capture and storage (CCS) methods have been extensively worked on, they are not economy-heavy, and their long-term environmental safety is a constant concern. Alternatively, carbon dioxide (CO2) biosequestration using photosynthetic microorganisms has emerged as a promising way in biomass application and production process and, consequently, at the same time, reducing carbon dioxide emissions. Although microalgae are a viable source of several valuable compounds, their industrial applications still face many challenges and are unfeasible. Therefore, it is essential to promote the capture of carbon through an integrated process capable of combining several operations and/or processes to add value to CO2 conversion and reduce costs. In that regard, an overview of carbon capture and utilization and the ability of microalgae to assimilate CO2 and synthesize it into a wide range of chemicals is initially addressed. Finally, the main integration processes within a microalgae biorefinery and the potential for using CO2 in integrating these bioprocesses are presented.
