“…At this temperature, the methanogens are saturated, and further increase makes them uncomfortable. This support what was earlier reported by other researchers that has worked in similar research (Franqueto et al, 2020; Hajji et al, 2016; Martínez-Gutiérrez, 2018). For the hydraulic retention time, it was noticed through the interactive plot that the yield was very high in the early days of the production and later started to decline.…”

“…It can be observed that as the temperature increases, the biogas yields keep increasing until a temperature is reached (35°C for oDMBY and 28°C for FMBY), whereby a further increase in temperature lowers the oDMBY and FMBY yields rapidly. This may be because of the sensitivity of the methanogenic bacteria that produce biogas to temperature changes beyond this range (Franqueto et al, 2020; Martínez-Gutiérrez, 2018). It was noticed that increase in the retention period up to 18 days improved the oDMBY and FMBY yields.…”

Optimising biogas yields from anaerobic digestion of organic wastes is significant to maximum energy recovery in the biodigestion process and has become an important topic of interest. Substrate particle size is an important process parameter in biogas production, and it precedes other pretreatments methods for the majority of the lignocellulose materials. Optimisation of biogas yield using Response Surface Methodology (RSM) was done, and temperature, hydraulic retention time and particle size were considered variables to develop the predictive models. Pretreatment of groundnut shells was investigated using particle size reduction of mechanical pretreatment methods. After pretreatment, 30 samples were digested in a batch digester at mesophilic temperature. The experimental results showed that the temperature, hydraulic retention time and particle size had significant effects of interaction ( p < 0.05). The optimum experimental and predicted yields are: 44.70 and 42.92 (lNkgoDM) organic dry matter biogas yield, 20.80 and 19.09 (lN/kgFM) fresh mass biogas yield, 24.00 and 22.68 (lNCH4oDM) organic dry methane yield and 12.30 and 15.59 (lNCH4FM) fresh mass methane yield, respectively. The R2 recorded for the four yield components were 0.6268, 0.5875, 0.6109 and 0.5547. These values seem to be lower and a sign of the average fit of the model. Biogas production from groundnut shells was significantly improved with statistical optimisation and the pretreatment method.

“…Vanegas and Bartlett [42] found a higher biogas yield at 35 • C than at 45 • C for AD of Laminaria digitata. Pfeffer [51] studied the AD of household solid waste at temperatures between 35 • C and 60 • C and found the two optima: one at 40 • C and another at 60 • C. Franqueto et al [52] observed the maximum biogas yield at 40 • C when they examined anaerobic co-digestion of animal waste with agricultural residue at varying temperatures (e.g., 36 • C to 60 • C). Membere and Sallis [53] found the biogas yield to be at its maximum at 35 • C when conducting an experiment at different temperatures (e.g., 25 • C, 30 • C, 35 • C and 55 • C).…”

Converting organic waste into energy through anaerobic digestion is gaining popularity day by day. The reactor temperature is considered as one of the most vital factors for the digestion process. An experiment was conducted in the Biogas Laboratory of Green Energy Knowledge Hub at Bangladesh Agricultural University (BAU) to examine the influence of temperature on anaerobic digestion of cow-dung. Laboratory-scale continuous stirred tank reactors with a working volume of 15 L were operated for a 30-day retention time. The reactors were set at 20 °C, 25 °C, 30 °C, 35 °C, 40 °C and 45 °C, respectively to determine the effect of temperature on anaerobic digestion performance. Different parameters like total solids, volatile solids, pH, volatile fatty acids, ammonia nitrogen, total nitrogen, biogas production rate and methane concentration were examined. Among all the reactors, the reactor at 40 °C temperature produced maximum biogas (312.43 L/kg VS) and methane yields (209.70 L/kg VS), followed by the reactors at 35 °C and 30 °C, respectively. Statistical analysis of the obtained experimental results using Minitab® (State College, PA, USA) showed that the optimum process performance in terms of methane yield and volatile solid degradation is achieved at a reactor temperature of 35.82 °C.

“…The initial parameter to determine the samples was the total solids, a balance between the inoculum and the substrate is considered crucial to achieve an optimal production of methane and biogas [15]. The moisture content established was 85%, recommended by [16]. The range of solids used in all tests did not require adding water to reduce the solids loading.…”

Tilapia production was 4.2 million tons in 2016, and almost half of the production came from aquaculture. At the same time, organic waste from breeding increases as the demand for tilapia production. An alternative to using such waste is the production of energy and organic fertilizers. The use of a co-substrate can help to achieve the moisture content necessary to feed the digester. The aim of this study was to determine the effect of the anaerobic co-digestion of bovine manure with residual sludge from tilapia fish breeding ponds in the production of sludge. Methane and CO2 production, chemical oxygen demand (COD), total solids (TS), total fixed solids (TFS), total volatile solids (TVS), volatile fatty acids (VFA), total nitrogen (TN), total phosphorus (TP) content, and microbiological parameters (fecal coliforms and salmonella) during composting were determined. The organic fertilizer obtained was evaluated by a germination and seedling growth assay. The results of this study showed that the mixture of bovine manure and residual sludge from tilapia fish breeding ponds (1:1) produced high methane and low CO2 in the composting process compared to the when these raw materials were composted individually. Alfalfa germination and seedling growth were significantly boosted by the application of sludge from the mixture of bovine manure with residual sludge from tilapia fish breeding ponds.
