Techno-economic analysis of bioethanol preparation process via deep eutectic solvent pretreatment

Advances in green solvents for production of polysaccharide‐based packaging films: Insights of ionic liquids and deep eutectic solvents

“…The synthesis of ILs consisting of biocompatible/natural compounds, such as choline, amino acids, and carboxylic acids, significantly increased (Foulet et al., 2016). Choline has been especially used in bio‐ILs as the cation, owing to its low price (200 USD/ton for choline chloride) (Peng et al., 2021) and high biocompatibility and low toxicity (Gadilohar & Shankarling, 2017). Bio‐ILs were also illustrated as effective and environmentally friendly ionic plasticizers for polysaccharide biopolymers, due to their capacity to form strong hydrogen bonds with polysaccharides (Figure 3) (Colomines et al., 2016; Decaen et al., 2017).…”

History repeats itself again: Will the mistakes of the past for ILs be repeated for DESs? From being considered ionic liquids to becoming their alternative: the unbalanced turn of deep eutectic solvents

“…Of the few papers dealing with techno-economic evaluations of processes involving DESs, three are related to the subject of this analysis. [353][354][355] Specifically, these reports describe the treatment of rice straw and switchgrass either with ChCl : LA or ChCl : EG with 1 wt% of H 2 SO 4 for the production of low molecular weight products. Two major conclusions can be drawn from these studies: (a) the development of multi-product biorefineries should be targeted in view of profitable and sustainable processes instead of a single, high- volume-low-value compound, and (b) the biomass/DES ratio should be as high as possible to reduce the costs of solvents required for the recovery of the biomass fractions from the DES system and for the overall DES recycling.…”

A guide to lignin valorization in biorefineries: traditional, recent, and forthcoming approaches to convert raw lignocellulose into valuable materials and chemicals

“…243 In addition, DESs recycling is challenging and the lack of effective methods represents a prominent limitation to the technoeconomic viability of DESs for biorenery applications. 247,248,253,254 Nevertheless, these green solvents are considered promising candidates for the pretreatment of lignocellulose and for the subsequent valorization of the isolated lignin. 246,247,255,256…”
