“…Monte Carlo simulation was conducted for the uncertainty analysis. This is a statistical method widely used to establish the odds for bio‐based chemical or electricity production systems . This analysis includes all the key impact factors discussed in the preceding section, which considers the variation of the price of furfural, lignin, acetone, and MIBK; the recycle ratio of MIBK and acetone; glucose and 2,3‐BDO yields; and discount rate, loan rate, and financing equity.…”

This study analyzed the techno‐economic feasibility of a biomass conversion process enabled by high‐solid loading deep eutectic solvent (DES) pretreatment for the co‐production of 2,3‐butanediol (BDO), furfural, and technical lignin. Aspen plus was used for process simulation; economic analysis models were developed to evaluate commercial potential; sensitivity analysis was carried out to evaluate the effects of key parameters on the production cost of 2,3‐BDO; and Monte‐Carlo simulation was used for uncertainty analysis. Two cases of high‐solid loading pretreatment (20% versus 27%) for DES pretreatment were compared. The process simulation results indicate that 78–79% of cellulose, 63–70% of xylan, and 40–44% of lignin in raw switchgrass are converted into 2,3‐BDO, furfural, and technical lignin, respectively. The minimum 2,3‐BDO selling price (MBSP) of these two cases is estimated to be 1703–1736 $ ton−1, which is about half of the current 2,3‐BDO market price. Sensitivity analyses show that the prices and recycle ratios of acetone and methyl isobutyl ketone (MIBK) have larger impacts on the MBSP, which indicates that further technical improvement should focus on reducing their consumption. The uncertainty analysis indicates that 20 and 27% solid loading systems have similar confident intervals, with 90% confidence interval of MBSP ranging from 1450–1990 $ ton−1. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The cost of production for the oil and biodiesel from microalgae is estimated to be USD 3.46 / L and USD 3.69 / L respectively. [22]. By contrast, biodiesel obtained from other crops is less expensive such as soybean biodiesel (USD 0.57 / L -USD 0.67 / L), Fischer-Tropsch biofuels from corn fiber (USD 1.13 / L -USD 1.28 / L) and rapid pyrolysis biodiesel from wood chips (USD 0.58 / L) [22,23].…”

Microalgae transform CO2 into a broad portfolio of biomolecules, and thus should be considered as a valuable biotechnological platform. Despite several research programs and global efforts to establish a sustainable microalgae-based industry, most applications have not transcended academic boundaries. This limitation raises from the high transformation costs when target products are biofuels or fertilizers. Microalgae biorefinery emerges as an alternative to improve economic competitiveness, as Under such a model scope, the process inputs come from industrial waste, while biomass exploitation prioritizes the highest value molecules followed by extraction of less valuable compounds. This review describes a wide range of microalgae exploitation schemes focused on new uses of its constituents, while discussing emerging technologies designed to improve production and efficiencies as well.Keywords: microalgae; biorefinery; biofuels; fertilizers; active biomolecules. Biorefinerías de microalgas: aplicaciones actuales y nuevas tecnologías en desarrolloResumen Las microalgas transforman el CO2 en un amplio portafolio de biomoléculas, por lo cual, son consideradas una valiosa plataforma biotecnológica. A pesar de múltiples programas de investigación y esfuerzos globales para establecer una industria sostenible basada en microalgas, la mayoría de las aplicaciones potenciales no han trascendido las fronteras académicas. Esta limitación se debe a los altos costos en la transformación del producto principalmente cuando se obtiene compuestos económicos como biocombustibles y fertilizantes. La biorefinería de microalgas surge como alternativa para incrementar la competitividad económica. En este modelo, los insumos del proceso provienen de residuos industriales, mientras que la explotación de la biomasa inicia con las moléculas de alto valor y finaliza con los compuestos menos valiosos. En esta revisión se describe un amplio abanico de esquemas de explotación de microalgas enfocado en nuevos usos de sus constituyentes. Además, se exploran las tecnologías emergentes destinadas a aprovechar esta biomasa de una manera más versátil y eficiente.

“…Current cultivation systems, at least at present, still suffer from too high expenditures when compared to other sources of biomass to render algae‐based biofuels profitable and competitive on the market. Several studies dealt with the analysis of production costs of biodiesel from microalgae, which came to different conclusions depending on the specifics of the production plants , . However, in all cases, the resulting price was at least six‐fold increased compared to biodiesel from conventional sources such as palm oil, wood, or soy plants.…”

Microalgae are often heralded as a miracle cure to solve future questions concerning energy and food supply of the world's population. This is due to their vastly superior area productivity compared to terrestrial plants and the feasibility of cultivating them independently of arable land and fresh water. Algal biomass can be used as food and feed as well as a source for a plethora of biofuels and high value products such as nutraceuticals and pharmaceuticals. This review article seeks to shed light on recent advances in microalgal technology and their potential for the production of biofuels.
