The energy demand is increasing dramatically during last years. Due to this, biomass has been considered as an interesting alternative for renewable energy production. The objective of this work was to evaluate the production of bioethanol, biogas and electricity for using plantain pseudostem and rice husk produced as agricultural wastes in Colombia through a biorefinery scheme. The chemical characterization of these residues was carried out to get the input data for the conceptual design of fermentation, anaerobic digestion and combustion processes. Finally a techno-economic evaluation was developed to compare the potential of each process. The rice husk biorefinery showed higher yields of biogas and electricity compared to the plantain pseudostem case. In general terms, it was observed that production costs of bioethanol (0.48 USD/kg against 0.82 USD/kg), biogas (0.27 USD/m 3 against 0.56 USD/m 3 ) and electricity (0.02 USD/kW against 0.03 USD/kW) were kept lower under a biorefinery approach compared to the stand-alone processes for the rice husk case. For plantain case all the results were negative both for stand alone and biorefinery cases. This work concluded that it is possible to take advantage of some agricultural wastes generated in Colombia under biorefinery scheme to produce bioethanol, biogas and electricity as source of energy to supply a fraction of the energetic demand in this country.

Fossil fuels, which are recognized as unsustainable sources of energy, are continuously consumed and decreased with increasing fuel demands. Microalgae have great potential as renewable fuel sources because they possess rapid growth rate and the ability to store high-quality lipids and carbohydrates inside their cells for biofuel production. Microalgae can be cultivated on opened or closed systems and require nutrients and CO 2 that may be supplied from wastewater and fossil fuel combustion. In addition, CO 2 capture via photosynthesis to directly fix carbon into microalgae has also attracted the attention of researchers. The conversion of CO 2 into chemical and fuel (energy) products without pollution via this approach is a promising way to not only reduce CO 2 emissions but also generate more economic value. The harvested microalgal biomass can be converted into biofuel products, such as biohydrogen, biodiesel, biomethanol, bioethanol, biobutanol and biohydrocarbons. Thus, microalgal cultivation can contribute to CO 2 fixation and can be a source of biofuels. This article reviews the literature on microalgae that were cultivated using captured CO 2 , technologies related to the production of biofuels from microalgae and the possible commercialization of microalgae-based biofuels to demonstrate the potential of microalgae. In this respect, a number of relevant topics are addressed: the nature of microalgae (e.g., species and composition); CO 2 capture via microalgae; the techniques for microalgal cultivation, harvesting and pretreatment; and the techniques for lipid extraction and biofuel production. The strategies for biofuel commercialization are proposed as well.
