“…The energy potential of fresh pseudo-banana stem Many studies have reported the BMP of dried banana stem to range from 195 to 256 mL g −1 VS [35][36][37][38]; these yields are much lower than the value obtained in this study. This disparity can be attributed to the fresh or wet nature of the banana stem used in the present study.…”

Background: The banana pseudo-stem is a low-lignin-content lignocellulosic biomass that can be used for methane production. In recent years, anaerobic digestion (AD) of dried banana stems for methane production has attracted considerable attention. However, there is limited information regarding methane production from the fresh banana pseudo-stem. The direct usability of fresh banana stems as a resource for renewable energy production through AD is a called upon prerequisite for an improved waste management system culminating in a sustainable as well as socioeconomic development of local banana-producing communities. Methods: In this study, three series of experiments were performed simultaneously to investigate the methane production from fresh banana pseudo-stems for the first time. The tests included size reduction, enzyme addition, and co-digestion of banana stems with cow manure.

“…Various mathematical models have been proposed to describe substrate and biomass concentrations as well as biogas production in a batch or continuous process reactor [14,19,48]. Among these models for anaerobic digestion, that of Ghaly et al [20] was found to be suitable for our study.…”

“…This paper presents a model that describes the kinetics of an intermittent flow UASB reactor treating brewery wastewater based on mass balance principles. We considered that untreated COD as the primary substrate with no additional oxidizing agents added into the reactor would be converted to biogas (CH 4 and CO 2 ) [48]. We also considered the reduction of COD to hydrogen gas and hydrogen sulphide as insignificant in this study [13].…”

Biogas produced from an upflow anaerobic sludge blanket (UASB) reactor is a clean and an environmentally friendly by-product that could be used to meet partial energy needs. In this study, a modified methane generation model (MMGM) was developed on the basis of mass balance principles to predict and increase methane production rate in a UASB reactor during anaerobic fermentation of brewery wastewater. Model coefficients were determined using the data collected from a full-scale reactor. The results showed that the composition of wastewater and operational conditions of the reactor strongly influence the kinetics of the digestion process. Simulation of the reactor process using the model was used to predict the effect of organic loading rate and temperature on methane production with an optimum methane production at 29°C and 8.26 g COD/L/day. Methane production rate increased from 0.29 to 1.46 L CH 4 /g COD, when the loading rate was increased from 2.0 to 8.26 g COD/L/day. The results showed the applicability of MMGM to predict usable methane component of biogas produced during anaerobic digestion of brewery wastewater. This study would help industries to predict and increase the generation of renewable energy by improving methane production from a UASB reactor. To the best of our knowledge, MMGM is the first reported developed model that could serve as a predictive tool for brewery wastewater treatment plant available in the literature.

“…Kinetic parameters in this anaerobic digestion process including the maximum specifi c growth rate of microorganism (μ max ) and the max. rate of substrate consumption (K) were derived from a plot of total substrate effl uent (St) against T as a hydraulic retention time (Zainol 2012), and the expression can be stated as Eq. (5) and (6).…”

Darwin, Fazil A., Ilham M., Sarbaini, Purwanto S. (2017): Kinetics on anaerobic co-digestion of bagasse and digested cow manure with short hydraulic retention time. Res. Agr. Eng., 63: 121-127.The anaerobic co-digestion of bagasse with digested cow manure was operated in 3 l semi-continuous reactor under mesophlic temperature at 34 ± 1°C. Short hydraulic retention time and high organic loading rate applied were 10 days and 3.465 kg volatile solids (VS)/m 3 .day, respectively. Anaerobic co-digestion of bagasse with digested cow manure obtained higher biogas yield (69 ml/g VS) compared with the anaerobic digestion of digested cow manure alone (20.42 ml/g.VS). Kinetic assessment revealed that the maximum specific growth rate, the maximum rate of substrate consumption, halfvelocity constant, endogenous decay constant and microbial growth yield obtained were 3.917 day -1 , 870.309 mg/mg, 15.09 mg/l , 8.1518 day -1 and 0.0193 mg/mg, respectively. This result indicated that a longer retention time was required to allow the bacterial growth.
