What is it about?
To meet the CO2 emission reduction targets, carbon dioxide capture and utilization (CCU) comes as an evolve technology. CCU concept is turning into a feedstock and technologies have been developed for transformation of CO2 into useful organic products

Why is it important?
At industrial scale, utilization of CO2 as raw material is not much significant as compare to its abundance. Mechanisms in nature have evolved for carbon concentration, fixation and utilization. Assimilation and subsequent conversion of CO2 into complex molecules are performed by the photosynthetic and chemolithotrophic organisms. In the last three decades, substantial research is carry out to discover chemical and biological conversion of CO2 in various synthetic and biological materials, such as carboxylic acids, esters, lactones, polymer biodiesel, bio-plastics, bio-alcohols, exopolysaccharides
Perspectives
CCU is used as a CO2 sequestration strategy exhibits certain limitations. An alternative approach would be CO2 mitigation and valorisation to convert CO2 into bioenergy, rather than relying on storage based on reliable chemical reactions mechanism of CO2 with catalyst.
