“…However, the BP of LPSW was measured to be 615.74 mL/g VS higher than the values of 169.63 and 448.68 mL/g VS of LPM reported by this study and Li et al, respectively. The BP values of 596 and 720 mL/g VS from FW presented by Dalkilic and Ugurlu and Wu et al respectively, were close to value of 615.74 mL/g VS of the LPSW in this study.…”

“…These conditions might affect the BP potential of 355.21 higher than that of 193. 36 Each reactor was manually shaken for 1 min twice a day. BP of FiR was 63.26 mL/g VS lower than the 184.62 mL/g VS value reported by Serrano et al 20 The batch reactors were 1 L and the content of the reactors was magnetically stirred and temperature was maintained by means of a thermostatic jacket containing water at 37 C. It is noted that suitable S/I ratio and reactors stirring might increase the BP.…”

“…Due to the versatility of OW, the anaerobic co‐digestion of OW is commonly used to improve the individual BP. Literature related to OW and their co‐digestion have found to be beneficial for BP including FVR and sewage sludge, chicken manure and microalgae, OFMSW and FVR, sorghum and cow manure, animal manures and lignocellulosic residues, farm wastes, pig manure and dewatered sewage sludge, cattle slaughterhouse wastes, and OFMSW and MSW incinerator ash . On the other hand, factors affecting AD include pH, temperature, inoculum, substrate/inoculum (S/I) ratio, substrate concentration, substrate C/N ratio, substrate particle size, substrate pretreatment, substrate mixing, hydraulic retention time (HRT) or SRT, organic loading rate (OLR), substrate characteristics, trace elements, etc .…”

Agricultural organic wastes (AOW) have the potential to provide bioenergy particularly found in biogas by anaerobic digestion (AD). In this study, the biogas production (BP) of AOW was obtained by batch AD with anaerobic digesters (500 mL) at 35°C incubator. The results showed that BP values in terms of volatile solids (VS) from rice husk, rice straw, flower residues, fruit and vegetable residues, wasted oyster shell residue (WOSR), fishery residues, livestock and poultry manures, livestock and poultry slaughter wastes (LPSW), and eight equally mixed wastes (EEMW) were 84.03, 193.36, 153.32, 76.27, 150.48, 63.26, 169.63, 615.74, and 172.83 mL/g VS, respectively. LPSW showed the highest μm of 16.99 mL/g VS‐d, the highest BP of 615.74 mL/g VS and the highest bioconversion efficiency of 65.98% compared to the other organic wastes. BP from the most AOW in Taiwan by AD was estimated to be 768,567,753 (743,522,223, excluding WOSR) m3/year. The annual BP of 768,567,753 m3/year of the eight total major AOW by AD was lower (∼20.11%) than 961,989,781 m3/year of the EEMW by anaerobic co‐digestion. Result also showed that modified Gompertz equation was suitable to describe BP accumulation and BP rate.

“…Biogas is produced in the anaerobic digestion (AD) process, where microorganisms split organic matter into smaller chemical substances in the absence of oxygen. The AD process produces biogas as well as digestate as a by-product [58]. The study considers a farm-based small-scale biogas plant.…”

Resilient operation of medium/large scale off-grid energy systems, which is a key challenge for energy crisis solutions, requires continuous and sustainable energy resources. Conventionally, micro energy grids (MEGs) are adopted to supply electricity and thermal energy simultaneously. Fossil-fired gensets, such as diesel generators, are indispensable components for off-grid MEGs due to the intermittent nature of renewable energy sources (RESs). However, fossil-fired gensets emit a significant amount of greenhouse gases (GHGs). Therefore, this study investigates an alternative source as an economical and environmental replacement for diesel gensets that can reduce GHG emissions and ensure system reliability. A MEG is developed in this paper to support a considerably large-scale electric and thermal demand at Ontario Tech University (UOIT). Different sizes of diesel gensets and RESs, such as solar, wind, hydro, and biomass, are combined in the MEG for off-grid applications. To evaluate diesel gensets’ competency, the diesel genset is substituted by an emission-free generation source named microreactor (MR). The fossil-fired MEG and MR-based MEG are optimized by an intelligent optimization technique, namely particle swarm optimization (PSO). The objective of the PSO is to minimize the net present cost (NPC). The simulation results show that MR-based MEG could be an excellent replacement for a diesel genset in terms of NPC and selected key performance indicators (KPIs). A comprehensive sensitivity analysis is also carried out to validate the simulation results.

“…In other words, it is of significant importance to match a range of physical parameters as shown in Table 4 with operating parameters, that is feedstock size, feeding rate, average household, cost of construction, maintenance cost etc. In the recent times, there exist biogas online calculators (Wu et al, 2016) and other computational dynamics for calculating biogas yield. In this case, the designed volume of expected biogas was validated with measurement of the actual biogas produced.…”

Engineered biological systems used for resource recovery often utilize anaerobic digestion to treat organic wastes by reclaiming the carbon as energy (methane gas) and a soil amendment (biosolids). This study explored the production of biogas from co-digestion of cow dung waste and water hyacinth (Eichhornia crassipes) using anaerobic biological conversion. Cow dung and water hyacinth biomass feedstock were collected from Abattoir and Ologbo River in Benin City, Nigeria. Samples were blended and substrate mixed in ratio 10:1 v/v due to balanced carbon/nitrogen (C: N) ratio of plant biomass and cattle rumen manure and charged into the fixed dome. Performance test was carried out after the biogas had been produced after twenty-one (21) days. The percentage composition of biogas produced shows that methane gas (CH 4) has 56.4%, carbon-dioxide (CO 2) is 35% and nitrogen (N 2) is 6.9%. Optimal production was found to be a function of temperature, hydraulic retention time, pH, concentration of bacterial population and overall design consideration of the digester. Scrubbers were fitted to rid the gas of hydrogen sulphide (H 2 S), CO 2 , ammonia (NH 3) and moisture. The gas was directed through a gas pipe to a burner for cooking in the staff canteen. This study is relevant for the implementation of Sustainable Development Goals (SDGs) and strengthening of the bio-based economy with respect to waste management. This can facilitate environmental and socioeconomic sustainability leading to reduced carbon foot print and reduction in solid waste accumulation.
