The project, developed by the University of Calabria, proposes the reuse of CO2 to enter it in photobioreactors in which algae with a high content oleic are grown. The algae metabolize CO2 to synthesize the molecules of which they are made.
Photobioreactors are cheap, have an important productivity per hectare, much more than allocate soil to specific oleic crops. Algae do not need nutrients but only of CO2 recovered from upgrading and sunlight.
From algae vegetable oils can be extracted that can be turned into bio-diesel by transesterification, or by entering them in the digesters, are derived considerable amount of biogas to be allocated to the production of biomethane. This will close the cycle of matter and energy.
