“…In a similar investigation, NP combinations of 500 mg/L nZVI + 4 g/L zeolite improve biogas production by 130.87% in compared to the control [82]. Similar results were obtained by Abdallah et al [137], who found that utilising Ni-Ferrite NPs at concentrations of 20, 70, and 130 mg/L enhanced biogas production by 30.8%, 28.5%, and 17.9%, respectively, in comparison to using only cattle manure. Additionally, Karlsson et al [138] reported that adding a combination of the chloride salts of Fe, Co, and Ni to a semi-continuous biogas reactor at concentrations of 500 Fe mg/L + 0.5 Co mg/L + 0.25 Ni mg/L, respectively, enhanced the biogas production by 23.91% in comparison to the control.…”

One of the most important techniques for converting complex organic waste into renewable energy in the form of biogas and effluent is anaerobic digestion. Several issues have been raised related to the effectiveness of the anaerobic digestion process in recent years. Hence nanoparticles (NPs) have been used widely in anaerobic digestion process for converting organic wastes into useful biogas and effluent in an effective way. This review addresses the knowledge gaps and summarizes recent researchers’ findings concentrating on the stability and effluent quality of the cattle manure anaerobic digestion process using single and combinations nanoparticle. In summary, the utilization of NPs have beneficial effects on CH4 production, process optimization, and effluent quality. Their function, as key nutrient providers, aid in the synthesis of key enzymes and co-enzymes, and thus stimulate anaerobic microorganism activities when present at an optimum concentration (e.g., Fe NPs 100 mg/L; Ni NPs 2 mg/L; Co NPs 1 mg/L). Furthermore, utilizing Fe NPs at concentrations higher than 100 mg/L is more effective at reducing H2S production than increasing CH4, whereas Ni NPs and Co NPs at concentrations greater than 2 mg/L and 1 mg/L, respectively, reduce CH4 production. Effluent with Fe and Ni NPs showed stronger fertilizer values more than Co NPs. Fe/Ni/Co NP combinations are more efficient in enhancing CH4 production than single NPs. Therefore, it is possible to utilize NPs combinations as additives to improve the effectiveness of anaerobic digestion. Article highlights Single NPs (e.g., Fe, Ni, and Co NPs) in low concentrations are more effective in increasing CH4 production than reducing H2S production. Optimal Fe, Ni, and Co NP concentrations enhance anaerobic digestion process performance. Addition of Fe, Ni, and Co NPs above tolerated concentration causes irreversible inhibition in anaerobic digestion. Effluent with Fe, Ni, and Co NPs showed stronger fertilizer values. Nanoparticle combinations are more effective for increasing the CH4 production than signal NPs.

“…Trace elements such as Ni and Co are considered significant constituents for cofactors and enzymes. Cobalt and Ni NPs not only enhance biogas and methane generation but also ameliorate the stability of the anaerobic assimilation process 160 . From the experimental studies, it was analyzed that the Co NPs at concentration of 1 mgL –1 increase biogas production by 71% and methane production by 41.9% in comparison with that of the control sample.…”

“…As an additive, TiO 2 adsorbs H 2 S in the form of oxides, therefore mitigating H 2 S emission. It was observed that C2 has an increased ratio of Fe 2 O 3 and TiO 2 because of which the chances of agglomeration increase thereby decreasing the mobility of NPs, hence decreasing the H 2 S reduction in comparison with C1 160,163 . The C1 mixture showed an H 2 S removal efficiency of 62.07% due to its synergistic effect and fewer collisions and aggregation of NPs.…”

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.

“…Nanoparticles of iron oxide and zero-valent iron enhance interspecies hydrogen transfer and direct interspecies electron transfer, explaining the excellent results obtained when they are supplemented into digestion systems [108]. Other metals (Cu, Co, Ag, Ni) and metal oxides have also been studied as supplements in anaerobic digestion in the form of nanoparticles [109][110][111][112]. Nanomaterials, in general, may become a useful ally in promoting substrate degradation due to their unique characteristics such as their high surface area, high reactivity, and specificity, and their increased number of active sites [113].…”

High-solid and solid-state anaerobic digestion are technologies capable of achieving high reactor productivity. The high organic load admissible for this type of configuration makes these technologies an ideal ally in the conversion of waste into bioenergy. However, there are still several factors associated with these technologies that result in low performance. The economic model based on a linear approach is unsustainable, and changes leading to the development of a low-carbon model with a high degree of circularity are necessary. Digestion technology may represent a key driver leading these changes but it is undeniable that the profitability of these plants needs to be increased. In the present review, the digestion process under high-solid-content configurations is analyzed and the different strategies for increasing reactor productivity that have been studied in recent years are described. Percolating reactor configurations and the use of low-cost adsorbents, nanoparticles and micro-aeration seem the most suitable approaches to increase volumetric production and reduce initial capital investment costs.
