“…In fact, both ILs and DESs have been shown to be excellent solvents for dissolving and further processing of biomass and cellulose in particular. [11][12][13][14][15][16] However, again, ILs are expensive and difficult to synthesize on a large scale, making their practical use on an industrial scale difficult at the moment. In contrast, DESs are usually less expensive than ILs and have also been tested as an alternative solvent for the extraction of cellulose from biomass and for further processing to generate fuels or plastic substitutes.…”

“…It has been suggested that ILs and/or DESs may revolutionize various industrial processes in the future, and much research has been carried out with regard to certain applications. Examples include CO 2 capture and separation, [4][5][6] lubrication and tribology, [7][8][9] biomass dissolution [10][11][12][13][14][15][16] and absorption heat transformers. 17,18 Herein, we briefly introduce some of these applications.…”

“…7 Among various methods used for pretreatment, deep eutectic solvent (DES) pretreatment has received considerable interest due to high pretreatment performance and selective removal of non-cellulosic components. [8][9][10] Prior studies on DES pretreatment showed that more than 90% glucose yield can be achieved by using choline chloride (ChCl)-based DESs as pretreatment solvents. 11 Ultrafast DES pretreatment was also realized within 45 s when assisted with microwave.…”

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

“…Through this quest, bioethanol produced from renewable resources has been justified to be a reassuring alternative method to overcome the energy crisis. 3 In most cases, bioethanol is preferably utilized in the form of petrol additive or direct usage for the engine of neat alcohol. Bioethanol is commonly blended with petrol in a ratio of 15% gasoline to 85% bioethanol.…”

Recently, the production of bioethanol is shifted to secondary bioethanol which is produced from nonedible lignocellulosic feedstock to avoid the food versus fuel issue. Mango leaves, a kind of nonedible lignocellulosic material (LCM) that possess a relatively 80.7% of holocellulose (inclusive of cellulose and hemicellulose), appear to be potential candidate to serve as cheap substrate source for bioethanol production. Hence, the objective of this article is to present the current scenario and the potential of mango leaves as a substrate source for bioethanol production. This article also provides an overview on various process parameters such as temperature, pH, substrate concentration, and incubation time that required to be optimized for an efficient fermentation process in the bioethanol production from LCM. Apart from that, several integrated fermentation technologies in bioethanol production which include separate hydrolysis and fermentation, simultaneous saccharification and fermentation, simultaneous saccharification and co‐fermentation, and consolidated bioprocessing will also be discussed in this article. Based on the findings, it is clear that mango leaves have the potential to serve as feedstock for bioethanol production.
