Deep eutectic solvents for improved biomass pretreatment: Current status and future prospective towards sustainable processes

Integrated techno-economic and environmental assessment of biorefineries: review and future research directions

“…Many studies relied on literature data and manual calculations (almost 50% of the studies in Table 1). In particular, the database from the National Renewable Energy Laboratory (NREL) 8,38 appears valuable for research on sustainable bioreneries, as it provides information on biomass feedstock, conversion processes, and product yields and tools for simulation and economic and environmental analyses. Concerning the indicators to evaluate economic viability, Capital and Operating costs (CAPEX and OPEX), internal rate of return (IRR), net present value (NPV), discounted payback period (DPP) and return on investment (ROI) are the most commonly used parameters.…”

“…37 Moreover, extraction methods can also be applied to recover extractable compounds of interest before further pre-treatment or conversion of the biomass to avoid their loss or degradation. 38…”

The dawn of aqueous deep eutectic solvents for lignin extraction

“…134 Conducting comprehensive assessments such as life cycle assessment (LCA) and techno-economic assessment (TEA) is essential to determine the sustainability of ADES in the lignin extraction. 135 Therefore, this section discusses the environmental friendliness and economic sustainability of ADESs in the field of biorefining.…”

Natural Deep Eutectic Solvents in the Synthesis of Inorganic Nanoparticles

“…Observing the potential for DESs, research was started to find combinations of components that would enable the production of more environmentally friendly solvents that would continue to offer the advantages of DESs. As a result of this research, a group of NDES comprising substances found in nature, specifically in primary metabolites, was identified in 2011 [ 8 ]. In the following years, new types of DESs were also developed, i.e., supramolecular deep eutectic solvents (SUPRADES) with cyclic oligosaccharides as acceptors of hydrogen bonds (HBAs) or hydrophobic deep eutectic solvents (HDESs) composed of hydrophobic compounds, such as tetrabutylammonium bromide, menthol, thymol and fatty acids as HBAs, along with long-chain alcohols and carboxylic acids as donors of hydrogen bonds (HBDs) [ 9 ].…”
