“…It is clearly seen that the combinations of nanoparticle can be used in different forms which makes the effect more attractive on the biogas production. Iron, nickle, and cobalt NPs combinations have been shown to improve the start-up of biogas production by Abdelwahab et al [69] In particular, the average biogas production of 30 mg/L Fe NPs + 2 mg/L Ni NPs + 1 mg/L Co NPs, 30 mg/L Fe NPs + 2 mg/L Ni NPs, 30 mg/L Fe NPs + 1 mg/L Co NPs, and 2 mg/L Ni NPs + 1 mg/L Co NPs during the first five days of digestion was 41.82 mL/g VS (7.5% increase), 43.24 mL/g VS (12.67% increase), 42.18 mL/g VS (8.43% increase), and 40.0 mL/g VS (2.8% increase), compared to 38.90 mL/g VS.…”

“…Additionally, Abdelwahab et al [69]. found that the combination of 30 mg/L of Fe NPs + 2 mg/L of Ni NPs + 1 mg/L of Co NPs produced the highest daily CH 4 production (25.76 mL/g VS on day 10), whereas every other NP combination produced less CH 4 on a daily basis.…”

“…Hassanein et al [76] observed a negligible difference between poultry litter alone (305 mL/g VS) and a low NP combination (321 mL/g VS), which contained a combination of 400 mg/L of Fe NPs + 12 mg/L of Ni NPs + 5.4 mg/L of Co NPs. According to Abdelwahab et al [69] the production of CH 4 may be efficiently increased by adding NP combinations. Furthermore, Fe, Ni, and Co NPs, which were able to combine the properties of each element to increase CH 4 yield, may be to responsible for the preference of the Fe/Ni/Co NP combinations over other NP combination additions and cattle manure alone.…”

“…In comparison to cattle manure alone, Abdelwahab et al [69] found that NP combinations of 30 mg/L Fe NPs + 2 mg/L Ni NPs + 1 mg/L Co NPs, 30 mg/L Fe NPs + 2 mg/L Ni NPs, and 30 mg/L Fe NPs + 1 mg/L Co NPs considerably decreased cumulative H 2 S production. Particularly, the total H 2 S production was 794, 791, and 902 ppm correspondingly, compared to 926 ppm for the cattle manure only.…”

“…In reality, the majority of NPs have the ability to bind to and maintain inhibitory elements such heavy metals on their surfaces [37,67]. NPs (such as Fe, Ni, Co, and metal oxides) promote the activation of microorganisms and important enzymes, increasing the production of biogas and CH 4 , and decreasing the concentration of H 2 S [68][69][70][71].…”

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.

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.
