Developing innovative synthetic technologies of industria relevance based on carbon dioxide as raw material

The reduction of carbon dioxide emission into the atmosphere requires the implementation of several convergent technologies in different production sectors. The chemical industry can contribute to the issue with innovative synthetic technologies, which implement the principles of atom-economy, dematerialization, energy saving, and raw material diversification with carbon recycling. Such methodologies based on carbon dioxide utilization merge two issues, namely, avoiding the production of CO2 and carbon recycling. In this paper, some options are discussed, such as the synthesis of-carboxylic acids, organic carbonates, and carbamates/isocyanates. Synthetic processes of methanol from either CO2 or CO are compared. The results of application of LCA to selected cases are discussed.
