During the XX century the great increase of the energy uses, nearly all from fossil sources, have brought on more and more significant growth of the CO2 rate in the atmosphere.

Abstract
During the XX century the great increase of the energy uses, nearly all from fossil sources, have brought on more and more significant growth of the CO2 rate in the atmosphere. As we know, this has produced important environmental effects, which are getting worse during the time. Certainly, the importance of this problem forces to research various solutions which can reduce or limit the CO2 emissions in atmosphere. At present, world policies about the reduction of fossil fuel uses, have failed. Consequently the aim could be to develop production cycles which convert the greenhouse CO2, recovered from power plant or human activities, into resource. In fact there are a lot of different cycles that use CO2 such as physical states: gaseous, liquid, solid and supercritical. In this paper the actual and perspective situation is analysed. To this aim, after a short examination of different uses of CO2, the best innovative and environmental among these are studied. A particular CO2 use (biomass production) has been examined.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
