“…Besides the lack of rigorous economic studies for large scale microalgae and cyanobacteria biomass production Molina Grima et al, 2003), it is significant to note that several of the technical and economic evaluations, even if based on estimations, are performed for continuous Cheng-Wu et al, 2001;Harun et al, 2011;Jaramillo et al, 2012;Marzocchella et al, 2010;Molina Grima et al, 2003;Powell and Hill, 2009) or semi-continuous (J.

The possibility of using photosynthetic microorganisms, such as cyanobacteria and microalgae, for converting light and carbon dioxide into valuable biochemical products has raised the need for new cost-efficient processes ensuring a constant product quality. Food, feed, biofuels, cosmetics and pharmaceutics are among the sectors that can profit from the application of photosynthetic microorganisms. Biomass growth in a photobioreactor is a complex process influenced by multiple parameters, such as photosynthetic light capture and attenuation, nutrient uptake, photobioreactor hydrodynamics and gas-liquid mass transfer. In order to optimize productivity while keeping a standard product quality, a permanent control of the main cultivation parameters is necessary, where the continuous cultivation has shown to be the best option. However it is of utmost importance to recognize the singularity of continuous cultivation of cyanobacteria and microalgae due to their dependence on light availability and intensity. In this sense, this review provides comprehensive information on recent breakthroughs and possible future trends regarding technological and process improvements in continuous cultivation systems of microalgae and cyanobacteria, that will directly affect cost-effectiveness and product quality standardization. An overview of the various applications, techniques and equipment (with special emphasis on photobioreactors) in continuous cultivation of microalgae and cyanobacteria are presented. Additionally, mathematical modeling, feasibility, economics as well as the applicability of continuous cultivation into large-scale operation, are discussed.

“…In this regard, oil extraction based on Chlorella vulgaris topology was analyzed using techno-economic assessment and environmental analysis. Four routes for producing methanol from shale gas were simulated and analyzed through economic and environmental assessments . Techno-economic analysis served to compare two methanol-propylene processes, indicating that evaluated topologies remain feasible if methanol price stays below 600 $USD/t .…”

These days, developing sustainable chemical facilities to generate biofuels, energy, bioproducts, and value-added chemicals has attracted attention. The above involves changing the traditional conception of transformation processes into more sustainable production based on the green chemistry principles, renewable energies, and the triple dimensions of sustainable development. Consequently, the addition of sustainability issues in process synthesis, analysis, and optimization of bioprocesses has become increasingly noteworthy. This study reports a literature review concerning the sustainable chemical process design framework based on process synthesis, analysis, and optimization methodologies. Studies on biorefinery/process synthesis approaches are analyzed and compared, offering a detailed overview of selected literature. These included hierarchical, mathematical, and mixed approaches. This review also outlined indexes and indicators for measuring sustainability in process design considering exergetic/energetic, environmental, economic, and safety aspects. It is worth mentioning the role that exergetic metrics are expected to play in measuring global process sustainability. Finally, the current research gap of process integration is analyzed, considering pinch analysis techniques, simultaneous heat and mass integration, and hybrid intensification−integration approaches.

“…For the RH case the proposed energy producing biorefinery is really an interesting alternative to other uses such as substrate for microalgae growth [49] and fermentative processes to produce lactic acid among other compounds [50], given the possible profits and massive utilization of all the residues in one facility with practically no limits in the market (given the existing high demand in Colombia for these energy products). Other uses of RH in the market as conglomerates, filling structures or substrates for fungi are very low added value alternatives.…”

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.
