“…This catalytic process also facilitates the solubilization of hemicelluloses derived from wheat straw, resulting in a dextrose yield ranging from 58% to 90% [61]. Additionally, the magnetic nature of the nanocatalyst makes its separation from the reaction mixture easy [93,97,134,135]. The nanocatalyst exhibited enzyme-like properties and removed approximately 44% of lignin from corncob biomass [136].…”

Biofuel, an inexhaustible fuel source, plays a pivotal role in the contemporary era by diminishing the dependence on non-renewable energy sources and facilitating the mitigation of CO2 emissions. Due to the many constraints in existing technology and the resulting increased costs, the production of biofuels on a large scale is a laborious process. Furthermore, the methods used to convert varied feedstock into the intended biofuel may vary based on the specific techniques and materials involved. The demand for bioethanol is increasing worldwide due to the implementation of regulations by world nations that mandates the blending of bioethanol with petrol. In this regard, second-generation bioethanol made from lignocellulosic biomass is emerging at a rapid rate. Pre-treatment, hydrolysis, and fermentation are some of the technical, practical, and economic hurdles that the biochemical conversion method must overcome. Nanoparticles (NPs) provide a very effective approach to address the present obstacles in using biomass, due to their selectivity, energy efficiency, and time management capabilities, while also reducing costs. NPs smaller dimensions allow them to be more effective at interacting with lignocellulosic components at low concentrations to release carbohydrates that can be utilized to produce bioethanol. This article provides a concise overview of various biofuels and the nanotechnological advancements in producing it, with a particular emphasis on ethanol. It provides a detailed discussion on the application of nanotechnology at each stage of ethanol production, with a particular emphasis on understanding the mechanism of how nanoparticles interact with lignocellulose.

“…Nanotechnology is mainly applied to the pretreatment of lignocellulosic biomass by acidfunctionalized magnetic nanoparticles mediated and nanoshear hybrid alkaline (NSHA). It has been reported that the 10.3389/fmicb.2022.933882 pretreatment of 500 mg g −1 of sugarcane bagasse with two types of acid-functionalized magnetic nanoparticles, alkyl sulfonic acid, and butyl hydroxy acid yielded 18.83 and 18.67 g L −1 sugar, respectively (Mahajan et al, 2020). Deng et al utilized the NSHA method for pretreatment of corn stover biomass to improve biofuel production.…”

For decades, lignocellulosic biomass has been introduced to the public as the most important raw material for the environmentally and economically sustainable production of high-valued bioproducts by microorganisms. However, due to the strong recalcitrant structure, the lignocellulosic materials have major limitations to obtain fermentable sugars for transformation into value-added products, e.g., bioethanol, biobutanol, biohydrogen, etc. In this review, we analyzed the recent trends in bioenergy production from pretreated lignocellulose, with special attention to the new strategies for overcoming pretreatment barriers. In addition, persistent challenges in developing for low-cost advanced processing technologies are also pointed out, illustrating new approaches to addressing the global energy crisis and climate change caused by the use of fossil fuels. The insights given in this study will enable a better understanding of current processes and facilitate further development on lignocellulosic bioenergy production.

“…And this is a solution that can bring tangible benefits. The impact of different substrate pre-treatment methods has been described in many publications (Mahajan et al, 2020;Skibko et al, 2021;Bandgar, Jain and Panwar, 2022). It is also worth considering the possibility of using an appropriately sized pre-treatment of the substrate and building smaller fermenters.…”

Anaerobic digestion is a demanding process, due to the large number of process and environmental factors that affect it. Many years of research of the various parameters have made it possible to optimise the process to obtain the maximum amount of biogas and methane contained in it, and this provides energy and environmental benefits. The article deals extensively with the operation of agricultural biogas plants, using the example of a plant that faces numerous operational problems. In order to identify the negative effects on energy yield and the equipment operating in the system, the substrate was examined, the data on its operation analysed, and solutions were proposed that should be taken into account in the further operation of the biogas plant. The analysis showed a good biogas yield from beet pulp of 563 dm3∙kg−1 of TS (total solid) and an average methane yield of 58%. With the analysis presented, it was possible to identify some operational problems. The biogas yield study also highlighted some errors made at the plant design stage. The most important of these is the use of an inappropriate organic matter loading factor for the digester, which leads to acidification of the contents and degradation of the methanogenic microorganism cultures.
