“…Sridhar [24] also studied the use of both calcined and natural eggshell to remove heavy metals (Pb and Cu) from real automotive wastewater, where high efficiency was attained. Amo-Duodu et al [25] reported 80% increase in biogas yield from sugar refinery wastewater by adding metallic nanoparticles (Fe, Ni, and Cu) at a hydraulic retention time of 10 days and mesophilic temperature of 40 • C. Despite the potential benefits of trace metals on biogas production [2,15,26] and wastewater treatment using the most prevalent materials such as activated carbon, alumina, and silica, [27,28], their extensive use is hampered by cost [29,30]. Therefore, exploring less expensive biomaterials as a source of nutrients and biostimulant for the AD process can make it more economically feasible.…”

In this study, the principle of sustaining circular economy is presented as a way of recovering valuable resources from wastewater and utilizing its energy potential via anaerobic digestion (AD) of municipality wastewater. Biostimulation of the AD process was investigated to improve its treatability efficiency, biogas production, and kinetic stability. Addressing this together with agricultural waste such as eggshells (CE), banana peel (PB), and calcined banana peels (BI) were employed and compared to magnetite (Fe3O4) as biostimulation additives via 1 L biochemical methane potential tests. With a working volume of 0.8 L (charge with inoculum to substrate ratio of 3:5 v/v) and 1.5 g of the additives, each bioreactor was operated at a mesophilic temperature of 40 °C for 30 days while being compared to a control bioreactor. Scanning electron microscopy and energy dispersive X-ray (SEM/EDX) analysis was used to reveal the absorbent’s morphology at high magnification of 10 kx and surface pore size of 20.8 µm. The results showed over 70% biodegradation efficiency in removing the organic contaminants (chemical oxygen demand, color, and turbidity) as well as enhancing the biogas production. Among the setups, the bioreactor with Fe3O4 additives was found to be the most efficient, with an average daily biogas production of 40 mL/day and a cumulative yield of 1117 mL/day. The kinetic dynamics were evaluated with the cumulative biogas produced by each bioreactor via the first order modified Gompertz and Chen and Hashimoto kinetic models. The modified Gompertz model was found to be the most reliable, with good predictability.

“…Other papers go a step further and report the presence of magnetite NPs in digestate when used as fertilizer for lettuce crops, which also presented a higher presence of NPs in lettuce biomass (21.0-1,920%). This study showed that the effects of the NPs remaining in the AD effluent must be considered in future works, an issue that is not treated in the scientific literature [56]. Probably, as this research is at an emerging point with new publications appearing each week, new effects of NPs on AD processes will be discovered and become a topic of novel research studies, especially in the use of advanced microbiological techniques and in the development of new AD reactor configurations.…”

Enhancement of Anaerobic Digestion with Nanomaterials: A Mini Review

et al. 2022

View full text Add to dashboard Cite

In recent years, the number of articles reporting the addition of nanomaterials to enhance the process of anaerobic digestion has exponentially increased. The benefits of this addition can be observed from different aspects: an increase in biogas production, enrichment of methane in biogas, elimination of foaming problems, a more stable and robust operation, absence of inhibition problems, etc. In the literature, one of the current focuses of research on this topic is the mechanism responsible for this enhancement. In this sense, several hypotheses have been formulated, with the effect on the redox potential caused by nanoparticles probably being the most accepted, although supplementation with trace materials coming from nanomaterials and the changes in microbial populations have been also highlighted. The types of nanomaterials tested for the improvement of anaerobic digestion is today very diverse, although metallic and, especially, iron-based nanoparticles, are the most frequently used. In this paper, the abovementioned aspects are systematically reviewed. Another challenge that is treated is the lack of works reported in the continuous mode of operation, which hampers the commercial use of nanoparticles in full-scale anaerobic digesters.

“…Hassanein et al [ 198 ] utilized the recovered effluent from the digester as a fertilizer source for Lactuca sativa . Despite approximately similar levels of N, P, K, Zn, Mn, Cu, and Na in both the digester effluents, i.e., NP fed (NPD) (continuous digester containing NP mixture, i.e., FeNPs 1000 mgL −1 , NiNPs 120 mgL −1 , and CoNPs 54 mgL −1 fed twice on days 84 and 202) and control (CND) (biogas feedstock was cow dairy manure in both the digesters), the L. sativa fertilized with NPD effluent showed higher amount of these nutrients in its biomass as compared to those fertilized with CND effluent (both the digester effluents were diluted to 1:13.8 using deionized water (7.6 L) divided into five loadings over the growth period of 57 days).…”

“…In one such study, Hijazi et al [ 192 ] reported that the environmental impact of electricity production from the nanoparticle (CoNPs, NiNPs, FeNPs, and Fe 3 O 4 NPs)-treated biomass was lesser as compared to the untreated biomass (control). Hassanein et al [ 198 ] fertilized Lactuca sativa with the diluted effluent recovered from the digester fed with NP mixture (FeNPs 1000 mgL −1 , NiNPs 120 mgL −1 , and CoNPs 54 mgL −1 ), and reported higher levels of N, P, K, Zn, Mn, Cu, and Na in the plant biomass which could be due to the increased nutrient uptake and translocation efficiency as a consequence of NP treatment. The recorded values of Fe, Ni, and Co in the plant biomass were below the reported toxic limits.…”

Graphical abstract The residual slurry obtained from the anaerobic digestion (AD) of biogas feed substrates such as livestock dung is known as BGS. BGS is a rich source of nutrients and bioactive compounds having an important role in establishing diverse microbial communities, accelerating nutrient use efficiency, and promoting overall soil and plant health management. However, challenges such as lower C/N transformation rates, ammonia volatilization, high pH, and bulkiness limit their extensive applications. Here we review the strategies of BGS valorization through microbial and organomineral amendments. Such cohesive approaches can serve dual purposes viz. green organic inputs for sustainable agriculture practices and value addition of biomass waste. The literature survey has been conducted to identify the knowledge gaps and critically analyze the latest technological interventions to upgrade the BGS for potential applications in agriculture fields. The major points are as follows: (1) Bio/nanotechnology-inspired approaches could serve as a constructive platform for integrating BGS with other organic materials to exploit microbial diversity dynamics through multi-substrate interactions. (2) Advancements in next-generation sequencing (NGS) pave an ideal pathway to study the complex microflora and translate the potential information into bioprospecting of BGS to ameliorate existing bio-fertilizer formulations. (3) Nanoparticles (NPs) have the potential to establish a link between syntrophic bacteria and methanogens through direct interspecies electron transfer and thereby contribute towards improved efficiency of AD. (4) Developments in techniques of nutrient recovery from the BGS facilities’ negative GHGs emissions and energy-efficient models for nitrogen removal. (5) Possibilities of formulating low-cost substrates for mass-multiplication of beneficial microbes, bioprospecting of such microbes to produce bioactive compounds of anti-phytopathogenic activities, and developing BGS-inspired biofertilizer formulations integrating NPs, microbial inoculants, and deoiled seed cakes have been examined.
