“…An excessive dosage of iron-based nanoparticles hindered the overall process resulting in reductions in biogas production. The results indicated that iron oxide NPs additives have a positive impact and improved biogas production by releasing two electrons due to oxidation to Fe 2+ under anaerobic conditions [ 77 ]. The electrons released by Fe can be consumed by inorganic CO 2 or acids and accelerated by the hydrogenation pathway and thus produce more CH 4 [ 77 ].…”

In this work, different pretreatment methods for algae proved to be very effective in improving cell wall dissociation for biogas production. In this study, the Ulva intestinalis Linnaeus (U. intestinalis) has been exposed to individual pretreatments of (ultrasonic, ozone, microwave, and green synthesized Fe3O4) and in a combination of the first three mentioned pretreatments methods with magnetite (Fe3O4) NPs, (ultrasonic-Fe3O4, ozone-Fe3O4 and microwave-Fe3O4) in different treatment times. Moreover, the green synthesized Fe3O4 NPs has been confirmed by FTIR, TEM, XRD, SEM, EDEX, PSA and BET. The maximum biogas production of 179 and 206 mL/g VS have been attained when U. intestinalis has been treated with ultrasonic only and when combined microwave with Fe3O4 respectively, where sediment were used as inoculum in all pretreatments. From the obtained results, green Fe3O4 NPs enhanced the microwave (MW) treatment to produce a higher biogas yield (206 mL/g VS) when compared with individual MW (84 mL/g VS). The modified Gompertz model (R2 = 0.996 was appropriate model to match the calculated biogas production and could be used more practically to distinguish the kinetics of the anaerobic digestion (AD) period. The assessment of XRD, SEM and FTIR discovered the influence of different treatment techniques on the cell wall structure of U. intestinalis.

“…The ranking of conductive iron oxide like Fe3O4 NPs-20 as the best alternative agrees with previous studies due to its ability to stimulate the growth of methanogens, promote the direct interspecies transfer of electron in syntrophic methane production, improvement of substrate solubilization, etc. [14], [18]. Similarly, amongst other additives studied in Abdelsalam et al [40], it was shown that the use of 20 mg/L Fe3O4 NPs (Fe3O4 NPs-20) achieved the highest biogas yield of 584 mL/gVS from the enhanced anaerobic digestion.…”

“…Similarly, Casals et al [15] reported the use of a novel, optimal and continued release of Fe3O4 NPs to the digester to achieve a 180 % rise in biogas yield. In the same vein, the addition of 15 mg/l Fe nanoparticle enhanced cattle manure by 38.2 % [18] It was also reported that the use of 100 mg/l trace iron aided the improvement of biogas recovery from food waste digestion [19]. There are varieties of iron-based additives that are being used for the enhancement of anaerobic digestion, but the selection of the appropriate iron-based additive could be a challenge due to the variation in properties and substrate types.…”

“…The selected iron-additive should be of low capital and operational costs, apply to a wide range of substrates, and ultimately increase biogas yield and methane content [11]. These iron-based additives should be able to promote the growth of methanogen, facilitates direct interspecies electron transfer in syntrophic methane production, improve ____________________________________________________________________________ 2021 / 25 425 hydrolysis, solubilization and acidification stages through the dissimilatory process of iron reduction and wields great potential in the degradation of complex organics [14], [18].…”

Enhancement of anaerobic digestion is vital for substrate solubilization and increased biogas production at a reduced cost. The use of several iron-based additives has proven effective in improving overall bio-digester performance during anaerobic digestion sludge. This study evaluates different iron-based additives for the selection of the best additive from the alternatives using a multi-attribute decision making (MADM) approach. The weights of the attributes were computed with the entropy weight technique and the ranking of the alternatives were performed using order preference by similarity to ideal solution (TOPSIS) method. Five attributes and thirteen frequently used alternatives were selected for evaluation. The result showed that additive cost and dosages were assigned the highest weight of 62.37 % and 27.46 %, respectively. Based on the performance scores of 99.15 %, 20 mg/L of Fe3O4 nanoparticles (Fe3O4 NPs-20) ranked best (number 1) among considered alternatives for enhancement of anaerobic digestion of sludge. The outcome of this evaluation agrees with previous experimental results and suggests that the choice of an effective iron-based additive should be based on its biogas enhancement potential and cost-effectiveness (low dosage requirement and low price).

“…Casals et al [132] reported a threefold increase in methane production when supplementing iron nanoparticles (NPs). Abdelwahab et al [133] studied the digestion of cattle manure and obtained a biogas yield of 0.953 L/g VS when evaluating a concentration of 15 mg/L of (Fe) NPs against a value of 0.589 L/g VS obtained from the control experiments. Not only was the biogas yield enhanced, but the presence of these particles also favored a lower production of H 2 S, which is of great relevance regarding subsequent biogas up-grading operations.…”

High-Solid Anaerobic Digestion: Reviewing Strategies for Increasing Reactor Performance

et al. 2021

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.
