“…Sewage sludge, an organic waste from wastewater treatment plants, is expected to continue growing worldwide due to the rising number of households connected to central treatment plants [32]. The presence of untreated sewage sludge can afflict the surrounding environments since the sewage sludge's general compositions are recalcitrant organic pollutants.…”

“…Bioenergy recovery from biomass resources may be achieved via the employment of several biomass conversion pathways [1,2]. A review of literatures, however, highlights an upsurge in the application of anaerobic digestion (AD) technologies in recent times [3,4]. This observation may be reflective of the strategic preference of this conversion pathway due to its capability to facilitate a simultaneous management of high moisture organic waste streams while also generating bioenergy in the form of biogas at a reduced cost [2,5].…”

“…The biogas product is typically composed of carbon dioxide (CO 2 ) and biomethane (CH 4 ) which are present in volumetric percentages of 30-40% and 60-70%, respectively [6]. However, although AD technologies for biogas production can be employed in the conversion of a multitude of organic streams to biogas under the action of suitable microbes, the degradation of sulphur containing organics, i.e., proteins, and the reduction of anionic species, i.e., SO 4 2− , will result in the associated generation of hydrogen sulphide (H 2 S)…”
