“…However, these high removed amounts could not be reflected on the removal percentages (SDE), since the supplemented organics were, on the other hand, so high. Whereas, higher loading and a shorter HRT overloaded the fermentation process . Previously, magnetite‐Fe 3 O 4 NPs exhibited substrate degradation performance of 1.5‐fold higher than control batch reactor …”

“…H 2 is the most recommended as energy carrier gas, since it is ecofriendly and produces water as combustion by‐product when it is utilized at fuel cell . Additionally, H 2 gas has a high heating value (net calorific value) of 33.3 kWh/kg which outperforms the heating values harvested from methane and natural gas of 13.9 and 13.1 kWh/kg, respectively …”

Summary Continuous H2 production from alkali‐hydrolyzed rice straw in two mesophillic anaerobic baffled reactors (ABRs) was investigated in parallel. ABR1 was inoculated with thermally pretreated sludge while the sludge in ABR2 was amended with magnetite nanoparticles (MNPs). Both reactors were operated at organic loading rates (OLRs) ranged from 0.8 to 4.8 gCOD/L/day. The addition of MNPs significantly improved the H2 production and yield, ie, maximum H2 yield was 21.4 ± 3.2 and 60.6 ± 5.7 mL/g CODremoved for both ABR1 and ABR2, respectively, at OLR of 1.6 gCOD/L/day. Likewise, substrate degradation efficiency (SDE) was augmented from 48.4 ± 3.9% (ABR1) to 55.8 ± 4.2% (ABR2). The enhancement effect of MNPs can be emphasized by hydrogenase enzyme activity increase from 0.097 ± 0.013 to 0.205 ± 0.019 mg MBreduced/min at ABR1 and ABR2, respectively. Besides, ABR2 witnessed higher concentrations of acetate (HAc) and butyrate (HBu) coupled with lower values of propionate (HPr). Additionally, HAc/HBu ratio for ABR2 (3.03 ± 0.31) was higher than that for ABR1 (1.95 ± 0.29). Microbial analysis indicated that Bacillus and Clostridium species became dominant in mixed culture bacteria supplemented with MNPs. Furthermore, economic analysis revealed that the minimum payback period of 10.5 years at OLR of 3.2 gCOD/L/day was recorded for ABR2 compared with 14.6 years at OLR of 4.8 gCOD/L/day for ABR1.

“…Dry anaerobic system refers to systems that able to anaerobically treat organic waste with solid content in the range of 20 -40%. These systems require a good mechanically pretreatment tool to sustain smaller particle size and robust pumps to handle impurities [21]. Table 1 illustrates a comparison between the most common three designs of Kompogas, Valorga and Dranco process.…”

Organic solid wastes are produced with large amount wherever there are human activities. However, improper treated organic wastes made them as sources of diseases. On the other hand, these fractions contain nutrients and energy, so they have also valuable resources. As a result, exploring their potential as an energy source can be accomplish via anaerobic digestion process, in which, organics converted into hydrogen, methane and/or ethanol. Therefore, this manuscript introduces an overview of the common applied types of reactor that can handle these types of wastes in their solid state and recover them in term of biogas, as well as, stabilize the produced digestate to bio-fertilizers by compositing approach. A comparison also listed to demonstrate the optimum operational conditions and expected amount of biogas from each type.
