It presents important advantages over first-generation biofuels: it enables the sustainable production of electric power through fossil fuels capturing CO2 the competition with agri-food productions is drastically reduced compared to other biofuels; and last but not least, the residue of the oil extraction from microalgae can be further exploited as it contains high value-added compounds like vitamins, antioxidants, and anti-microbial substances.<br \/>\nDespite the apparent simplicity of the process, its implementation at the industrial scale is still not widespread since it is characterized by technical and economic constraints that might hinder its full scale-up.<\/p>\n<h4>Overview<\/h4>\n<p>The CRS4 contribution to this subject is the development of mathematical simulation models and complex computer codes that enable the evaluation of the reactor and process configurations, aiming at the optimization and speed up of the algae growth. These models also allow to evaluate the distribution of the photon flux needed to trigger the conversion of CO2 in bioenergetics algal oil. Furthermore, protocols for genetic modification of microalgae are under development to enable an increased growth rate and an improved efficiency in the use of photonic flow. Finally, some innovative experimental protocols of non-polar lipid extraction from process residues are under implementation to achieve high value-added products, such as antioxidants, omega3 and others.<\/p>\n<h4>Innovative features<\/h4>\n<ul>\n<li>optimization of configuration and reactor performance via software without any additional cost due to field tests;<\/li>\n<li>reduction of CO2 produced from thermal power plants;<\/li>\n<li>production of high value-added products from waste and process residues;<\/li>\n<li>production of high value-added products from waste and process residues;<\/li>\n<\/ul>\n<h4>Potential users<\/h4>\n<p>Main beneficiaries include companies emitting CO2 as a result of their production cycle, companies operating in the production, refining and distribution of biofuels as well as the transport sector in general. Further potential users are the companies operating in the field of nutraceuticals (dietary supplements and antioxidants) and the pharmaceutical-biomedical industries (antivirals, phycobiliproteins, etc.)<\/p>\n<h4>Impact sectors<\/h4>\n<p align=\"JUSTIFY\">ompanies generating power from fossil fuels \u2013 Biofuels and chemical industry \u2013 Pharmaceutical industry \u2013 Agri-food industry \u2013 Cosmetic industry.<\/p>\n<h4>Other resources<\/h4>\n<ol>\n<li>Alessandro Concas,\u00a0<a href=\"https:\/\/www.youtube.com\/watch?list=PL8DF3B5DD666628CC&amp;v=WSfQAVwkEGo\">Biofissazione di anidride carbonica con microalghe e produzione di biocarburanti.\u00a0<\/a>Collana Seminari per la valorizzazione dei risultati della ricerca al CRS4, Cagliari, 29 Marzo 2012.<\/li>\n<li>Alessandro Concas, Massimo Pisu and Giacomo Cao.
