“…The addition of ZVI NPs fastens the degradation of VFAs, due to which the pH of the system rises dramatically and the process of biogas generation is retrieved. With the introduction of ZVI NPs, the relative percentage of bacteria involved in hydrolysis process was also found to enhance, leading to 77.3% improvement in the overall biogas yield 50 …”

“…This further impairs methanogens' capacity to break down VFAs and lowers methane generation. 49,50 It is also crucial to substitute traditional carbon-abundant crops meant for utilization by humans with renewably generated biomasses as substrates for the anaerobic breakdown process. Likewise, the availability of LCF in comparably higher amounts has drawn particular interest.…”

“…With the introduction of ZVI NPs, the relative percentage of bacteria involved in hydrolysis process was also found to enhance, leading to 77.3% improvement in the overall biogas yield. 50 The ZVI NPs also possess significant adsorbing capacity; hence they are useful in removing contaminants such as heavy metals (Hg 2+ , Ni 2+ , Zn 2+ ), polyphenols, sulfated compounds (such as H 2 S), chlorinated compounds, and aromatic hydrocarbons (Fig. 5).…”

In a world where fossil fuels are running out, biofuels are one of the best green energy alternatives to fuels made from petroleum due to their environmentally beneficial qualities and low cost in comparison with non-renewable fossil fuels. Biofuels are produced from cheap and renewable sources and the energy stored in these biomasses can be assimilated to create sustainable electricity or heat, which can then be exploited to meet current and future societal needs in numerous situations. However, the production of biofuels on an industrial scale takes a lot of time because of the numerous constraints placed on currently available technology and the increased costs that go along with them. Moreover, the processes utilized to transform various feedstocks into the desired output also vary based on the materials and techniques employed. The supply of biofuel feedstocks is large, and with improved processing, we could significantly lower our reliance on fossil fuels. In this context, the use of nanoparticles (NPs) is a commendable solution to the present problems with biomass use, especially given their low cost. The unique qualities of nanomaterials, such as excellent catalytic properties, high surface area-to-volume ratio, remarkable selectivity, and reusability make them admirable tools for boosting biofuel generation. This review predominantly focuses on the contributions of nanotechnology and various immobilization methodologies in accelerating biofuel production from biomasses that might fill in the research gap, which was previously limited by the relatively lower efficiency of traditional techniques of biofuel generation.

“…The addition of trace elements can provide the necessary nutrients for the growth of microorganisms [84]. Wei et al supplemented the anaerobic co-digestion of corn stover and chicken manure with trace elements, and the results indicated that the addition of trace elements can change the microbial community structure and affect the digestion performance [85].…”

The bibliometric method was used in this study to analyze current advances in the anaerobic digestion (AD) of cellulose waste. The result shows that the number of articles increased rapidly after 2010, suggesting a growing interest in this field. The USA and China were the top two countries with the highest number of published articles. AD of cellulose waste is being actively explored in many countries, and partnerships between countries are being actively formed. The top three subject categories were Environmental Sciences & Ecology, Engineering, Energy & Fuels. The most widely published and influential journals were Bioresource Technology, Water Science and Technology, and Waste Management. The co-occurrence and trend analysis of author keywords indicates that current research is primarily focused on pretreatment and co-digestion. Microbial community analysis plays a crucial role in elucidating the mechanisms, and life cycle analysis (LCA) could evaluate the impact on the environment at different stages. Microbial community analysis and LCA will be the hotspots in the future. To some extent, this study helps to understand the current global status and trends of the related research.
