As the annual production of carbon Dioxide (CO2) reaches 30 billion tones, the growing issue of the greenhouse effect has triggered the development of technologies for CO2 sequestration, storage and use as a reactant. Collecting together the reports of the Congress at University of Rome (Campus Bio-medico) held 16th April 2012, CO2: A Valuable Source of Carbon presents and discusses promising technologies for the industrial exploitation of CO2.  Divided into two parts, the current technology is evaluated and summarized before European and national projects are presented. The focus on CO2 recovery, particularly in value-added production, proposes applicable methods to develop sustainable practices  and even to mitigate greenhouse gas emission from large-scale fossil fuels usage.  Including current data and real-world examples, CO2: A valuable source of carbon  provides students, engineers, researchers and industry professional with up-to-date material and potential areas for development and research.
