“…[ 29c ] Chen et al use a biphasic solvent system (choline chloride/methyl isobutyl ketone (ChCl/MIBK)) to selectively convert lignocellulose into furfural and coproducts through a one‐pot reaction. [ 56 ] The research integrates the biomass pretreatment, conversion, and separation processes together. High yield of furfural (84.04%), 93.1% purity of lignin, and cellulose‐rich material (73.1%) can be obtained by using the biphasic solvent system (0.6 wt% H 2 SO 4 , 10.7 wt% solid loading) at 170 °C for 60 min.…”

“…[ 44 ] Under the optimized conditions (170 °C, 60 min), the biphasic solvent can dissolve 96% xylan from raw switchgrass, which is simultaneously converted to furfural with a yield of 84.04%. [ 56 ] The biphasic solvent is also able to selectively extract lignin with a high purity (93.1%) at the same time. The dissolved pulp is cellulose (73.3%) rich materials, which can be completely hydrolyzed into glucose within 48 h via enzymatic hydrolysis.…”

“…[ 44 ] The aqueous ChCl/MIBK biphasic system is an effective solvent system for co‐production of furfural, high quality technical lignin, and digestible cellulose for further upgrading. [ 56 ] Gao et al investigated the utilization of inorganic salt solutions as adjuvants with ILs for rice straw pretreatment. After the pretreatment with the mixture of 40% 1‐ethyl‐3‐methylimidazolium chloride, 53% water, and 7% K 2 CO 3 at 110 °C for 1 h, the residues are highly susceptible to enzymatic hydrolysis, achieving 92.07% sugar yield and 93.70% of lignin removed.…”

cellulose (30-50 wt%), hemicellulose (20-35 wt%), and lignin (15-30 wt%). [3] CO -C bonds are the main connection bond in the components, but between different components hydrogen bond is the main connection. [2b,4] Cellulose is the most abundant component composed by d-glucose units linked to each other via β-1,4-glycosidic bonds, a certain amount of cellulose shows ordered crystal structure. [5] Hemicellulose is composed with various polymerized monosaccharides, mainly are C5 (xylose, arabinose) and C6 sugars (mannose, glucose, and galactose), and others, which acts as a linkage distributing between cellulose and lignin. [6] Lignin is one kind of highly complicated cross-linked 3D amorphous resin, which is composed of three monolignols (p-coumaryl, alcohol, coniferyl alcohol, and sinapyl alcohol) connected by different CO -O bonds. [1a] Lignin mainly lies on the surface of cellulose and hemicellulose that ensures the structural integrity and rigidity of biomass. [3,7] Currently biomass catalytic conversion has achieved great success in breaking CO -C bond, so converting single component to platform chemicals or materials is quite close to industrialization. The key of efficient application of whole biomass becomes the separation of different components with high efficiency. Owing to the complex structure of biomass, biomass fractionation is the key process for the full and efficient utilization of this renewable resource. [8] In the previous reports, various solvent systems, such as strong dilute acid treatment, [9] alkaline treatment, [10] the sulphite pulping process, [11] and organosolv isolation, [12] were used to separate cellulose, hemicelluloses, lignin, and their derivatives. However, most of those traditional methods always cause serious environmental consequences and result in more cost in waste disposal owing to the application of large amounts of acids and bases. [13] By contrast, ionic liquids (ILs) [8a,b,14] and deep eutectic solvents (DESs) [4,15] are widely regarded as a green alternative solvent for their near-zero vapor pressure, high thermal stability, devisable structure, and excellent solvent power for biomass. [4b,8b,16] Not like acid or base pretreatment methods that need destruction and then fractionation of biomass components, ILs and DESs methods can achieve highly selective fractionation of biomass by controlling the functional structure of ILs or composition of DESs. [4b,8a,14b,16] According to the existing reports, many ILs and

Presently, researchers are focusing on environmentally friendly and economical chemicals to pretreat the LF with the goal of lignin and impurities free fiber [17,18]. Choline chloride (ChCl) is emerging as a new solvent for lignocellulose processing that ultimately stimulates the concept of the green environment.…”

In this work, the effects of chemical pretreatment and different fiber loadings on mechanical properties of the composites at the sub-micron scale were studied through nanoindentation. The composites were prepared by incorporating choline chloride (ChCl) pretreated rice husk waste (RHW) in low-density polyethylene (LDPE) using melt processing, followed by a thermal press technique. Nanoindentation experiments with quasi continuous stiffness mode (QCSM) were performed on the surface of produced composites with varying content of pretreated RHW (i.e., 10, 15, and 20 wt.%). Elastic modulus, hardness, and creep properties of fabricated composites were measured as a function of contact depth. The results confirmed the appreciable changes in hardness, elastic modulus, and creep rate of the composites. Compliance curves indicated that the composite having 20 wt.% of pretreated RHW loading was harder compared to that of the pure LDPE and other composite samples. The values of elastic modulus and hardness of the composite containing 20 wt.% pretreated RHW were increased by 4.1% and 24% as compared to that of the pure LDPE, respectively. The creep rate of 42.65 nm/s and change in depth of 650.42 nm were also noted for the composite with RHW loading of 20 wt.%, which showed the substantial effect of holding time at an applied peak load of 100 mN. We believe that the developed composite could be a promising biodegradable packaging material due to its good tribo-mechanical performance.

The growing worldwide concern over the environmental impact of our heavy dependence on fossil fuels has provided impetus for biomass utilisation to produce fuels and chemicals. A cost-effective conversion technology stands as a challenge for biobased fuels and chemicals to be competitive with petroleum-derived products. This review provides an overview of the recent advances in the conversion technologies of biomass, which includes thermochemical and biochemical processes. With a plethora of conversion technologies available, the choice of suitable conversion technology depends on the biomass feedstock availability and the desired end-product. It is observed that present research is focused on the development of catalysts and optimisation of process parameters to improve the economics of conversion technologies. Efforts are also on towards utilisation of cheaper substrate, lignocellulosic biomass and CO 2 -sequestering algae. Though few technologies have reached the commercial stage, conversion technologies for lignocellulosic and marine biomass are still evolving. Further, much impetus is being given to process optimisation for deriving platform chemicals from biomass for value addition and sustainability of the biorefinery concept. Some key developments in these areas are presented in this review.
