“…The FTIR spectra of the OS also exhibit peaks at 1647 and 1507 cm −1 , which originated from aromatic rings and the C=C bonds. Moreover, the C-H deformation from aromatic skeletal vibrations from lignocellulosic structures was confirmed by bands that appear at 1425, 1321, and 898 cm −1 [21,[23][24][25].…”

“…The wide peak at 3355 cm −1 originated from stretching and flexural vibrations of hydrogen bonds from the O-H group, while the peak that appears at 2918 cm −1 can be ascribed to symmetric C-H valence vibrations from cellulose, hemicellulose, and lignin [21,22]. Furthermore, the peaks at 1600, 1258, 1162, 1110, 1054, and 1035 cm −1 indicate the presence of hydrogen-containing functional groups, such as COO-, C-O, and/or C-O-C, while the peaks at 1458 and 1375 cm −1 implied the presence of C-H bends from lignin, cellulose, and hemicellulose [21,[23][24][25]. The FTIR spectra of the OS also exhibit peaks at 1647 and 1507 cm −1 , which originated from aromatic rings and the C=C bonds.…”

In the proposed study, agro-waste biomass oat straw (OS) was considered a potential adsorbent for Cu(II), Zn(II), and Se(IV) removal from aqueous solutions. In order to obtain material with better adsorption abilities, the OS was modified by a deep eutectic solvent (DES). Structural changes caused by the applied modification route were considered by pHpzc, SEM, FTIR, and DSC/TG analysis. These methods discovered that lignocellulosic biomass degradation and material functionalization were achieved by DES treatment. Preliminary adsorption tests showed an over fourfold increase in capacity upon modification. The kinetic parameters implied that adsorption on modified material followed the pseudo-second-order kinetic model. Different isotherm models were applied to experimental data, while the Sips isotherm model best describes the equilibrium of the adsorption process on the tested modified material. According to this isotherm model, the maximum achieved adsorption capacities of Cu(II), Zn(II), and Se(IV) were 48.21, 55.06, and 87.85 mg/g, respectively. The summarized experimental results revealed that the adsorption process of selected cations on modified OS was predominantly caused by chemisorption, while, in addition to chemisorption, electrostatic forces were also responsible for Se(IV) removal. Desorption test showed that the prepared material could be reused for at least 3 cycles, with minimal efficiency loss. Briefly, this study reinforces that DES-modified agro-waste biomass could be used as a promising adsorbent for cations and oxyanions from wastewater.

“…There has been an attempt to utilise M × g on agricultural marginal soil with the optimisation of the yield and quality of biomass [32]. Significant progress has been recently made regarding M × g biomass processing to derived bioproducts [33] and market share [34,35], as this cellulose-rich material has been processed into energy [28,[36][37][38], insulation materials [39], pulp [23], paper [40], biopolymers [41,42], and cellulose nanocrystals [43].…”

Miscanthus × giganteus (M × g) is a promising energy crop in phytotechnology with biomass production. Despite considerable vegetation and harvest under varying climate conditions and across different soils, field-scale studies on utilising M × g remain scarce. Analysing the literature and our own findings, this study intends to highlight the potential of M × g phytotechnology for revitalising non-agricultural lands (NAL), including brownfields, and illustrate the expediency of applying biochar to enhance biomass yield, energy efficiency, and economic feasibility. To validate the feasibility of M × g production on brownfields, two scenarios within the value chain “biomass–biogas–electricity” for green harvest were examined. The assumptions were as follows: (1) a methane yield of 5134 m3 ha−1 y−1, and (2) substrate-specific methane yields of 247 and 283 mL (g oDM)−1 for the first and subsequent years, respectively. The findings suggest that Scenario 2 is better suited for cultivating M × g on brownfields/NAL, being more sensitive and eliminating inaccuracies and the generalisations of results. From the third year onward, the revenue of M × g production on biochar-amended brownfields showed greater potential for future profitability. Future research should confirm the positive trend in the energy efficiency ratio of M × g phytotechnology on a larger scale, particularly in real brownfield applications.

“…Furthermore, the MNB rupture process can produce a high-speed jet, which can not only remove the residual lignin but also impact the properties of micro/nano fibers (Chen et al, 2020;Babicka et al, 2022;Jacob Rani and Venkatachalam, 2022). In non-wood straw, the cellulose contained natural hierarchical porous, which could facilitate the contact between MNBs and cellulose.…”

Cellulose extraction accounts for 70% of the total production cost required for the preparation of micro/nano cellulose. Conventional pretreatment methods cause equipment corrosion and generate non-recyclable waste liquids. Thus the industrial-scale preparation of micro/nano cellulose is limited. To overcome this limitation, herein, a method is proposed, where in a mild alkaline pretreatment is combined with the micro-nano bubble (MNB) treatment, for the extraction of cellulose from bagasse. A delignification rate of >92% was attained, micro/nano cellulose was exposed on the pulp surface owing to the MNB treatment; the 4-h MNB treatment resulted in the complete exposure of micro/nano fibers. The production cost for this process was only 3.19 USD/kg CNFs, about 70.9 times lower than that for TEMPO oxidation. An appropriate MNB treatment time (1 h, 2 h) allowed the retention of moderate micro-fibers, which enhanced the maximum tensile force and tensile strength of micro/nano cellulose paper by about 50%. The results revealed that the proposed method serves as an efficient, green, and sustainable strategy for the large-scale and low-cost production of micro/nano cellulose.
