“…Secondly, it is allowed to expose on steam. Commonly, CO 2 and steam are known to be mild oxidizing agents that are applied for slow oxidation which lead for enlargement of existing pores (Bharathi et al., 2022). Metals, surfactants, agriculture residues, and industry wastes are can be act as additives that can potentially improve the adsorption capacity of biochar.…”

The generation of sewage wastewater is unavoidable due to the continual increase in the global population that paves the way to appropriate disposal management. Sewage wastewater treatment and consequent generation of sewage sludge (SS) are well connected with global environmental issues. Upon risk assessment on different SS disposal methods, converting SS into biochar, that is, sewage sludge biochar, can be recommendable management. It is well‐proven for excellent positive impacts, such as nutrient enhancement, and healthier plant growth, and mitigates the emissions of greenhouse gases while amending with agricultural soil. However, the outcome features of SSB significantly vary with pyrolysis temperature and its elemental constituents. In addition, many studies revealed that the process temperature is key to responsible for the desirable properties and functioning of SSB. In this context, many countries support to the development of a futuristic strategy for SS management toward producing SSB and its utilization in agriculture. This review compiles studies into SSB's ability to promote a sustainable effect on the total worldwide output volume. Furthermore, the generation of SSB is also analyzed from a socioeconomic standpoint in relation to other common SS disposal management strategies.

“…They boost catalytic activity, selectivity, and stability. Bharathi et al (2022) (19) employed iron oxide nanoparticles to boost bacterial growth, minimize retention time, and produce biogas from food waste. Nanocatalysts' high surface area and reactivity help convert organic waste into biogas.…”

: The province of Burdur is at the forefront of the livestock industry, especially with dairy cattle. it is a necessity for Burdur province to use animal manure, convert it into methane gas, and use it as fuel. In this study, a laboratory-scale biodigester was set up to produce biogas from cattle feces taken from Burdur Mehmet Akif Ersoy University Cattle Farm. γ-Fe2O3, meso-Fe2O3, and meso-Co3O4 nanoparticles (NPs) were synthesized and used as catalysts for biogas production. Structural characterizations of catalysts were carried out via FT-IR and XRD techniques. The TEM was used to investigate particle size distributions and morphology. The average particle sizes of the nanoparticles were determined to be in the range of 20-165 nm. The bio-digester was kept at a constant temperature of 35 °C for 20 days. It has been determined that the obtained biogas has a high methane content of 83–86%. The biogas volume was obtained to be 1.360 L/kg for γ-Fe2O3, 1.390 L/kg for meso-Fe2O3, and 625-1.250 L/kg for Co3O4.

“…Indeed, iron ions (Fe 2+ and Fe 3+ ) are essential constituents of cofactors and enzymes, and their addition to anaerobic digesters can improve the activity of methanogen Archaea microorganisms. However, very few experimental works have focused on the use of Fe 2 O [13] and Fe 2 O 3 [14][15][16][17].…”

The anaerobic digestion (AD) of biomass is a green technology with known environmental benefits for biogas generation. The biogas yield from existing substrates and the biodegradability of biomasses can be improved by conventional or novel enhancement techniques, such as the addition of iron-based nanoparticles (NPs). In this study, the effect of different concentrations of Fe2O3-based NPs on the AD of brown macroalga Sargassum spp. has been investigated by 30 days trials. The effect of NPs was evaluated at different concentrations. The control sample yielded a value of 80.25 ± 3.21 NmLCH4/gVS. When 5 mg/g substrate and 10 mg/g substrate of Fe2O3 NPs were added to the control sample, the yield increased by 24.07% and 26.97%, respectively. Instead, when 50 mg/g substrate of Fe2O3 NPs was added to the control sample, a negative effect was observed, and the biomethane yield decreased by 38.97%. Therefore, low concentrations of Fe2O3 NPs favor the AD process, whereas high concentrations have an inhibitory effect. Direct interspecies electron transfer (DIET) via Fe2O3 NPs and their insolubility play an important role in facilitating the methanogenesis process during AD.
