“…The relationship between intention and age appeared to be neutral, likely due to the limited exposure to renewable energy concepts in educational institutions, as well as the infrequent discussions about them in home settings. This finding is supported by the observations of François et al (2023), who revealed no correlation between respondents' age and their willingness to use biogas based on human excreta.…”

Understanding the spatial variation of factors driving interest in bioenergy is important for designing effective energy policies. Although previous authors have broadly explored the determinants of biomass supply intentions in the field of bioenergy, the potential spatial variation of these factors has received limited consideration from bioenergy research. We performed a structural equation modeling based on the theory of planned behavior to investigate the impact of spatial disparities on factors determining people’s intentions to supply forestry residues for clean energy. Our data were generated through a survey of 247 participants randomly sampled from two contrasting geographic regions (north and south) of the Republic of Benin. We found that spatial disparities altered the effects of attitude and knowledge of renewable energy while income and perceived behavioral control exhibited consistent positive effects across geographical regions. Our findings imply that ignoring spatial disparities when analyzing bioenergy acceptance can lead to distorted inferences. These findings can be used as a baseline information by policymakers to develop region-specific actions for achieving local transition toward clean energy in the Republic of Benin.

“…Biogas-forming bacteria require anaerobic conditions to produce optimal biogas. Biogas production process studies were carried out to obtain optimal conditions for biogas formation [7]. Processing cattle waste into environmentally friendly biogas is a very profitable technique because it does not damage nature so the ecological cycle is maintained [4].…”

Politeknik Negeri Jember has dairy cows TEFA which produce relatively large amounts of cow dung waste, namely 280 kg per day. The fecal waste is directly thrown into waterways, causing air pollution, namely causing an unpleasant odor. It would be interesting to conduct research on cow dung waste in TEFA of dairy cows. This research was carried out with the aim of utilizing cow manure which is waste in TEFA dairy cattle as raw material for biogas with a mixture of banana peel waste as a substrate. In this research, a batch system reactor with an anaerobic fermentation method was used. The variables used were the ratio of cow manure to banana peel waste with variations of 1:1, 1:2, 1:3, and the pH variable variations of 6, 7, and 8. The test parameter observed in the research was the volume of biogas. The experimental design used to determine optimum conditions is the Response Surface Method (RSM). The experimental design was carried out on 2 variables with 3 variations so that 9 data points were obtained. Based on the test results, it is known that the optimum conditions for the variable ratio of cow dung to banana peel waste and pH are 1:3 and the pH variation is 6, where the volume of gas produced is 177.8 ml.

“…The addition of microparticles to anaerobic digestion processes holds the potential to improve the process by providing larger active sites for the various microorganisms involved. Additionally, microparticles may serve as crucial mediators, capable of breaking cell membranes and facilitating direct electron transfer [22,23]. Concerning the substrate, the introduction of microparticles can accelerate the hydrolysis of organic matter, thereby enhancing substrate decomposition, increasing biogas production, and reducing the lag phase [24].…”

Wine lee generation, a by-product of the wine industry, implies economic challenges for producers in terms of management due to its high organic load and low pH value. Biological treatment based on controlled anaerobic digestion may emerge as a viable management alternative given its promising potential for biogas production thanks to the organic content of the substrate. However, the complex properties of wine lees may lead to microbial activity inhibition and process kinetics failure. Various solutions have already been explored, including co-digestion with other substrates, or the application of different pretreatments, to mitigate the effects of the accumulation of phenolic compounds, volatile fatty acids, antioxidants, or the acidic pH value of the medium. In this study, laboratory-scale batch reactors were established, adding iron- (magnetite) or carbon (graphite)-based microparticles to assess their impact on the kinetics of the process. The results demonstrate a significant improvement of 35% in the potential production of biomethane after four days of operation with graphite particles and 42% after five days using magnetite particles. Methane production rates, as determined by the Gompertz model, were 45.38 and 46.54 mL CH4∙gVS−1∙d−1 for the application of graphite and magnetite microparticles to the medium, respectively, compared to the value of 33.46 mL CH4∙gVS−1∙d−1 for the control trial, confirming kinetic process improvements of 36% and 39%, respectively. Evidences of the acceleration of the methanogenesis phase were detected along the essays; however, the strong inhibition mediated by the carboxylate accumulation was not avoided in any of the tested conditions.
