“…Higher operating temperatures, lower substrate concentrations and lower lignin content provide higher biogas yields. Although the oil seed cake contains some lignin, most of the lignocellulosic matrix degrades during oil extraction, resulting in a low C/H ratio (9-12) and a high CH 4 yield (Choi 2020a;Paritosh et al 2021). In this study, 0.56 (mL/g•VS) of methane production was measured for R3, which produced about twice as much methane gas than sugarcane straw or fallen leaves.…”

“…Lignocellulosic biomass feedstock has great potential in anaerobic co-digestion due to its abundance, low cost and high availability throughout the year. However, the slow hydrolysis rate of lignocellulosic-based biomass in general limits the single digestion of these highly recalcitrant feedstocks, which is often addressed by utilizing expensive pretreatment (Chen and Brewer 2021; Paritosh et al 2021). Pretreatment to improve the stability of the anaerobic process has been used to loosen the structure of the biomass, release more readily degradable components, increase the accessible surface area, and remove toxic saponins from the oil seed cake (Chen and Brewer 2021; Grübel et al 2019).…”

The aim of this study was to investigate sewage sludge reduction and biogas production using two-stage anaerobic co-digestion of sesame oil cake and sewage sludge. In the first stage (acidogenic fermentation), sesame oil cake (SOC) was acid fermented to produce fermented sesame oil cake (FSOC). In the second step (anaerobic co-digestion), sewage sludge and FSOC were mixed in various ratios of (100:0 (R1), 70:30 (R2), 50:50 (R3), and 30:70 (R4)) and observed for 30 days at a mesophilization temperature of 25 ± 2 °C. In the anaerobic co-digestion using FSOC as a co-feedstock, the VS and TS removal were in the range of 53.7 - 64.9% and 42.6 - 53.2% for R2 and R3, respectively. The highest cumulative biogas production (1740.43 mL) and methane production (1253.11 mL) were achieved with the R3. In addition, R3 had the shortest reaction delay time (λ), and stabilization of the process was the fastest of all samples. The co-digestion performance index (CPI) was determined to be 1.29, 1.39, and 1.10 for R2, R3, and R4, respectively. The highest value for R3 confirmed the highest synergistic effect. This suggests the possibility of biogas production using sesame oil cake.

“…To compete with present-day fuel demand, appropriate methods are required to produce hydrogen and methane. Despite the advantages of single-stage dark fermentation or anaerobic digestion (AD) processes, novel techniques must employ for global biogas production (Rasapoor et al, 2020;Paritosh et al, 2021). Recent research has led to the development of two-stage anaerobic digestion process, which divides into two different phases (acidogenesis and methanogenesis) (Thungklin et al, 2018).…”

The excessive use of fossil has resulted in the drastic exhaustion of natural energy sources, leading to environmental challenges and energy crises. Owing to rising energy demand there is a dire need to shift towards renewable energies from lignocellulosic biomass. The present study assessed the co-production of biohydrogen (H2) and biomethane (CH4) by utilizing a less explored halophyte Atriplexcrassifolia. Various reaction parameters were evaluated for their effect on biohydrogen and biomethane production in batch experiments. One parameter at a time experimental strategy was chosen for production optimization. Hydrogen and methane yields along with their production rates were assessed at different incubation times, temperatures, pH, substrate concentrations, and inoculum sizes in acidogenesis and methanogenesis stages, respectively. In the first stage, maximum cumulative hydrogen production of 66 ± 0.02 mL, with hydrogen yield of 13.2 ± 0.03 mL/g, and hydrogen production rate (HPR) of 1.37 ± 0.05 mL/h was attained when the reaction mixture (5 g Atriplexcrassifolia and 10 mL pretreated sewage sludge) was processed at 37°C and pH 5.5 after 48 h of incubation. While in the second stage, maximum cumulative methane production, i.e., 343 ± 0.12 mL, methane yield (MY) of 8.5 ± 0.07 mL/mL, and methane production rate (MPR) of 0.8 ± 0.05 mL/h was achieved after 18 days of incubation of reaction mixture (40 mL of hydrogenic slurry with 80 mL inoculum) at 45°C and pH 8. Furthermore, a 51% and 24% rise in biohydrogen and biomethane production respectively were recorded when the gases were produced at these optimized reaction conditions. The results ensure halophyte Atriplexcrassifolia as an imperative renewable energy resource and proposed that effective optimization of the process further increased the coproduction of biohydrogen and biomethane.
