“…Compared to alternative treatment methods, the merits of AD include low sludge production, high organic loading rates, energy value of methane and low energy consumption [9,10]. In the light of current global consciousness of environmental sustainability, AD is regarded as a promising process, both as a renewable energy generation scheme [11][12][13] and a waste stabilization method [14][15][16][17]. Anaerobic digesters further contribute to reduce greenhouse gas emissions [12,13,18].…”

This article reviews the experimental and theoretical studies conducted on the possible effects of oxygen in biogas generating anaerobic digesters. The interactions of oxygen with various biochemical processes associated with anaerobic digestion are discussed together with other relevant aspects. The conventional perception of oxygen being merely toxic in anaerobic digestion (AD) is refuted. Digesters can withstand significant levels of oxygenation without drastic negative impacts. Limited quantities of oxygen can even lead to improved AD reactor performance under certain operating conditions. Co-existence of anaerobic and aerobic cultures in a single bioreactor environment has been demonstrated. It is shown that the partial aeration assisted AD can serve as a beneficial treatment strategy for simultaneous waste treatment and energy generation, for a multitude of organic waste categories.

“…China, which was among the first countries which systematically developed biogas technology for rural communities, experienced that large scale biodigester often showed some drawbacks for rural implementation. Some of the reasons were the high cost and complication in maintenance [2]. Therefore, as a complementary alternative to the well known large scale biodigester, several initiatives in designing small scale biodigester for household purposes have been applied in Indonesian rural areas.…”

Abstract. Experiments were conducted in a horizontal continuous biodigester constructed of 12" ID PVC pipe of 4m, 5m, and 6m length to produce biogas from cow manure slurry. Mathematical models were developed based on a simplified mechanism of anaerobic digestion. The purpose of this attempt was to analyze the digestion phenomena quantitatively and objectively in order to make quick decisions in the optimization of the installed biodigesters in the field. The data from field measurements were used to fit the mathematical model for predicting the rate of biogas production and the selectivity of methane production over carbon dioxide formation. The mathematical models described in this paper were reasonably good to fit the experimental data. Simulation using the model led to more systematic field trials to improve the biodigester performance. The analysis resulted in two useful hints for the practical improvement of the biodigesters. Firstly, the selectivity of methane over carbon dioxide was significantly affected by the ratio of water and manure in the slurry. Secondly, the conversion of the organic matters into biogas could be increased by recycling a portion of the biodigester effluent.

“…Community awareness, increase of green energy, promotion of sustainable development of village, acceleration of environmentally friendly agriculture, rural household savings improvement, and rural energy equity as well as the quality of rural life increase [4][5][6][7]. This condition is supported by some factors such as shift of inal energy consumption from conventional energy dependence to public renewable energy empowerment to save energy and environment protection initiatives [8,9]. However, the development of renewable energy in rural areas is relatively slow because it involves high initial cost spending mostly on energy generation, research and development, and implementation [10][11][12][13].…”

Consumer Behavior - Practice Oriented Perspectives

The development of renewable energy technologies (RETs) in rural areas requires acceptance of technical solutions by key stakeholders, such as consumers and decision-makers, as well as energy providers. This study aims to identify the current status of public acceptance of RETs, especially biogas technology, the associated inluencing factors, and the villager's preference of role to biogas management. Questionnaires were distributed to the respondents in Bendosari village to collect the required data for logistic regression and measurement of willingness to pay (WTP). Bidding game format was used to assess the WTP of three diferent groups, that is, biogas farmer, non-biogas farmers, and non-farmers. Three regression models were generated from the analysis, describing the factors inluencing the public acceptance of each group toward biogas technology. The determinants of one group difered from the other group, relecting the customer behavior in deciding toward certain goods which is biogas technology in this case. Measurement of public acceptance in percentage indicates the high acceptance and low acceptance of biogas technology for biogas farmers and for other two groups, respectively. This is airmed by the result of the WTP-ATP comparison where WTP is lower than ATP and indicates that biogas technology has no important value for most non-biogas farmers and non-farmers. Furthermore, the preference of role as a consumer in biogas technology development is higher than as provider or co-provider. Biogas technology in rural areas is more sustainable when most farmers have roles as a co-provider.
