“…'Night soil' is a traditional term used for HE collected in the night to avoid humans getting intimidated by the mention of their own mess (Muthuniranjan & Murugan, 2020;Parab et al, 2021). As the population of humans increase, the burden to increase food production grows, and is consistent with the generation of huge volume of excreta (Hadiyarto et al, 2020). Almost all cultures across the globe practiced the recovery (sometimes as night soil) and use of HE for agricultural purposes dated back to several millennia (Mkude et al, 2021;Nordin, 2010;Timmer & Visker, 1998).…”

“…A medium to produce biogas from FS (biodigester -Figure 2a) can be a plastic bag, bottle, metallic container or a plant built with reinforced concrete cement for small-and large-scale biogas production. Normally, the volume of the biogas generated is measured using the water displacement method and can be stored using a gas balloon or a liquid displacement chambers in large plants (Hadiyarto et al, 2020;Jha, 2005). In the literature, 0.1-0.4 kg of HE with a pH range of 4.6-8.4, 77% water and 23% dry matter is said to generate 0.35-0.5 m 3 /kg (or 0.02-0.028 m 3 /kg dry waste) of biogas (Adjama et al, 2022;Andriani et al, 2015;Mudasar & Kim, 2017).…”

“…Approximately 25% of phosphorus from HE in Europe finds their way into soils for food production, according to Kooij et al (2020). HE contains low C/N ratio ranging from 6-15 and is unsuitable for biogas production unless diluted (Andriani et al, 2015;Hadiyarto et al, 2020). Excreta having low C/N ratio will inhibit anaerobic digestion, thereby accumulating high amount of volatile fatty acid and ammonia resulting in low biogas yields (Colón et al, 2015;Sun et al, 2017).…”

Biofertilizer, biogas and the chemical substances in those two, which are generated as a result of several treatment methods fecal sludge (FS) are usually subjected to, can be recovered for diverse applications. The treatment methods are classified into traditional and innovative methods. FS sludge impacts the environment negatively and one of the most adopted methods for its treatment from toilets where they originate, are composting and anaerobic digestion to recover biogas and organic fertilizer. FS potential for biogas production has been critically examined here using literature sources. It is discovered that FS is not largely favored as a means of recovering bioenergy in most parts of the world due to hygiene concerns, even though it is one of the most abundant organic materials for bioenergy recovery through anaerobic digestion. This work hence studied the factors hindering FS recycling and reuse, which it convincingly addresses. The work also demonstrates ways FS can be safely collected and digested to useful products and make a case for future investment in the sector by relevant bodies due to its feasibility, profitability and environmental-friendliness. Implementation of a system that recovers FS from latrines of households and public places and converts them to useful products are therefore recommended.

“…In addition, the significant variation in these biochar surface areas might be altered by the main chemical component of the initial raw material. Rice husk, mainly cellulose, lignin and silica, has a C/N ratio of approximately 80 [39]; corncob has a C/N ratio of 40 [40]; and manure has a C/N ratio of 21 [41]. These C/N ratio values indicate the resistance level of the material in the heating process, where materials with a high C/N ratio are more challenging to break down compared to materials with a lower C/N ratio.…”

The increased animal production in recent decades has increased manure production, which has become a significant source of agricultural waste. Although the abundant nutrient content in manure has the potential to be used as an alternative fertilizer, its natural decomposition process will be harmful to the environment. Composting and using manure as organic fertilizer have an adverse effect on the environment, as manure emits CO2, CH4, and N2O, which are harmful to the environment. Converting this animal waste into biochar through pyrolysis might be a better way to apply it to the soil. We reviewed papers to determine the potential of agricultural waste biochar, focusing on animal waste biochar, to combat soil quality degradation and mitigate greenhouse gas (GHG) emissions. Due to the scarcity of animal waste biochar information, some discussions are based on other agricultural waste types, mainly rice hull and corncob biochar. Applying biochar has been proven to be a suitable method for improving soil quality, forage productivity and reducing GHG emissions. More detailed research is needed to evaluate the potential of animal waste biochar in this regard.
