This survey research based study sought determinants of biogas technology adoption in rural areas of Pakistan. Stratified random sampling technique was employed to select respondents because the population was unknown and heterogeneous in nature. Total 240 respondents (150 biogas users and 120 potential users) were selected and face to face interviewed using a structured, validated and pre-tested questionnaire. Along with descriptive analysis of data logistics regression model was applied to investigate the determinants of biogas adoption. Findings affirmed significant role of socio-economic characteristics of respondents in the adoption of biogas technology. Empirical findings reported a significant impact of education, the income of households and the number of animals on the adoption of biogas technology. This implies that unit increase in education, income and number of animals will escalate the adoption of biogas technology. Tackling energy crisis, economic benefits, and production of slurry for soil fertility, health gains and environment-friendly nature of biogas were perceived reasons of biogas adoption among the biogas users. Non-government organizations and neighbours were leading motivational factors behind adoption as revealed by users. However, role of electronic media, print media and government institutionsin promoting biogas was reported dismal. This study urge that biogas is valuable alternative source of energy to combat energy crisis. In this way, provision of subsidies, interest free loans and technical backstopping could invoke potential users to adopt biogas technology.

Full textAbstract:
Biogas is a renewable energy source consisting mainly of methane, carbon dioxide, and other impurities. A purification process is required to remove the impurities (biogas upgrading and purification) to meet the requirements as an energy source for vehicles. Removal of CO2 from the biogas stream, which accounts for about 40% of the impurities, is necessary to produce biogas (mainly methane) for use in vehicles. Chemical absorption of CO2 using a rotating packed bed was considered due to its high CO2 absorption efficiency and small column size. Aspen Plus and Visual Fortran software were used to develop the model, and monoethanolamine (MEA) was used as the absorbent. The developed model was validated with experimental data, where the relative error is less than 10%. The process analysis performed shows: (a) biogas purity increases with rotation speed. (b) An increase in lean solvent concentration leads to an increase in CO2 capture efficiency and biomethane purity. (c) An increase in biogas throughput leads to an increase in biogas purity. The study may be useful for the design and operation of intensified CO2 capture from biogas streams for vehicle applications.

Full textAbstract:
While energy-related sectors remain significant contributors to greenhouse gas (GHG) emissions, biogas production from waste through anaerobic digestion (AD) helps to increase renewable energy production. The biogas production players focus efforts on optimising the AD process to maximise the methane content in biogas, improving known technologies for biogas production and applying newly invented ones: H2 addition technology, high-pressure anaerobic digestion technology, bioelectrochemical technology, the addition of additives, and others. Though increased methane concentration in biogas gives benefits, biogas upgrading still needs to reach a much higher methane concentration to replace natural gas. There are many biogas upgrading technologies, but almost any has methane slip. This research conducted a life cycle assessment (LCA) on membrane-based biogas upgrading technology, evaluating biomethane production from biogas with variable methane concentrations. The results showed that the increase in methane concentration in the biogas slightly increases the specific electricity consumption for biogas treatment, but heightens methane slip with off-gas in the biogas upgrading unit. However, the LCA analysis showed a positive environmental impact for treating biogas with increasing methane concentrations. This way, the LCA analysis gave a broader comprehension of the environmental impact of biogas upgrading technology on GHG emissions and offered valuable insights into the environmental implications of biomethane production.

To combat climate change, the Chinese government has implemented a package of policies to support the development of the biogas power generation industry. However, the promotion of biogas power generation technology in China is relatively slow. Therefore, it is of practical significance to study the promotion of biogas power generation technology against the background of policy support. In order to study the effect of policy on the promotion of biogas power generation technology, a system dynamics model is constructed in this paper. The results show that under the feed-in tariff subsidy policy, biogas power generation technology can be well promoted because it has good economic and environmental effects. In addition, if the biogas power generation technology is considered to participate in carbon emission trading, the carbon price also has a positive impact on the promotion of biogas power generation technology because it increases the perceived economic value of biogas power generation projects. Finally, this study can also provide reference value for the promotion of biogas power generation technology in other areas.

Full textAbstract:
Globally, biogas technology has been touted by academics, international organizations, United Nations, and pressure groups, among others, as an effective tool for protecting the planet against degradation. As such, stakeholders in the biogas technology sector have made some policy recommendations toward that goal. These include a global campaign in support of energy for sustainable development, climate financing by the international community, all countries adopting appropriate national strategies, innovative financial mechanisms, and encouraging private-sector participation in achieving the goal. Clearly, for countries to promote accessibility and create favorable perceptions on the adoption of biogas technology requires institutional involvement and collaboration. That is, institutions need to participate and contribute in terms of ideas and expertise as well as work together to ensure the dissemination and uptake of biogas technology in Ghana. This study is aimed at assessing the level of institutional involvement and collaboration and barriers to biogas technology dissemination in Ghana. A qualitative method was employed, and data were collected from 101 respondents through interviewing. The results indicated that the involvement of government and financial institutions in disseminating biogas technology was low, while biogas service providers showed moderate involvement. With regard to collaboration, it was revealed that institutions moderately collaborate in awareness creation but had low collaborations for promotion, monitoring, and evaluation. Furthermore, the lack of a national biogas policy, low government commitment towards biogas technology, and low financial support were key barriers to effective institutional involvement and collaboration in disseminating biogas technology in Ghana. It is recommended that the government shows a high commitment by providing the needed resources for dissemination activities and task the Ghana Energy Commission to formulate a national biogas policy to facilitate dissemination and adoption. Finally, a national biogas steering committee composed of all relevant stakeholders, including the Finance Minister or a representative from the Finance Ministry would create a good platform to help champion the dissemination of biogas technology in Ghana.

Abstract. Hydrogen sulfide in biogas is one of the most obstructive factors on utilization of biogas as fuel gas. At present, a domestic desulfurizing process of biogas in wide-spead use is the ferric oxide process. But this process has its disadvantages: the high cost and difficult regeneration of the desulfurizer, the secondery pollution the process caused. As a new technique, the bio-desulfurization of biogas has drawn more and more attention recently. This dissertation, with the experience of engineering abroad bio-desulfurization, is focused on providing a clue or a reference for the research and application of this technique in the future.

Even though biogas technology has been introduced in Indonesia since 1990’s and having the potential, the rate of biogas adoption in Indonesia runs slowly. It is important to understand factors encouraging or discouraging potential adopters to build biogas plant. The development of livestock sector especially cattle farming in Indonesia can be seen as the opportunity to increase the rate of biogas adoption. This study investigated the factors affecting households of cattle farmer to adopt or not to adopt biogas technology. A cross-sectional research survey was carried out by using structured questionnaires as the primary tool to collect data from both biogas adopters and non biogas adopters in Pati regency, Indonesia. Socioeconomic characteristic of potential biogas adopters plays an important role to ensure the adoption of biogas technology sustainable. Socioeconomic characteristic regarding having high social status determines individual to adopt biogas relatively earlier than other members of a social system. Having high income and education enables traditional farmers to finance biogas plant by their own money or access aid from the government or other agencies. Among other attributes of innovation, relative advantage of installing biogas plant is the most determinant attribute to speed the rate of biogas adoption. Having biogas plant was perceived as better option and generated more benefits compared to previous technology or method.Article History: Received May 17th 2017; Received in revised form August 5th 2017; Accepted Sept 6th 2017; Available onlineHow to Cite This Article: Wahyudi, J.

Biogas is an innovation that is already known among livestock farmers. Urutsewu Village uses biogas in an effort to meet energy needs derived from cow dung, chicken dung, tofu liquid waste, and kitchen waste. The purpose of this study was to analyze the perceptions of biogas users towards the installation, economic impact, environmental impact, and social impact of biogas installation in Urutsewu Village. This research was a descriptive research with data collection conducted through direct interviews with biogas users. The source of information data was obtained from 48 respondents consisting of households that own biogas digesters and households that use non-owners of biogas digesters. The results of the study showed that 67% of biogas users knew about biogas before using it and 33% after using biogas. Respondents tended to say that biogas technology is easy to implement, easy and simple maintenance. The perception of biogas users regarding environmental impacts is that biogas technology can reduce pollution, reduce sources of disease and improve environmental quality. Biogas technology can relatively save fuel costs and is cheaper than other fuels but is not sufficient as cooking fuel. The community agrees to process waste into biogas and supports the government in biogas processing

In order to reduce emissions of greenhouse gases, related global warming and dependency on fossil fuels, it is crucial to promote the uses of renewable energy, and conversion of biomass and organic waste into energy sources. In many parts of the world, a substantial increase in efforts for the conversion of waste into energy is currently being observed. Specifically, biogas technology has been emphasized for the conversion of animal waste into biomethane/biogas because livestock waste is considered to be a substantial source of ambient greenhouse gases, causing climate change. While biogas technology, an anerobic process to convert livestock waste into biogas, is promoted in both developed and developing countries, this review article is focused on improving our existing understanding of small-scale biogas technology and relevance of this technology in rural environment of India. A thorough review research has been performed to gather the information on livestock population, manure production, and potential of biogas technology in India to provide a wholistic information. A summary of the financial supports facilitated by various agencies, the cost of biogas plants, potential uses, and potential challenges in the dissemination of biogas technology in India has been discussed in this study. We anticipate that the data and interpretation provided here will help in understanding the scope of biogas technology in India and will help in formulating the policies which will support the implementation of biogas technologies in developing countries.

This paper presents an overview of biogas purification technology and industry status, studies the purified rules in biogas purification processing and a lot of experiments are made to verify the influence of purification efficiency by various influencing factors. Carbon dioxide in biogas, which occupies at least 30%, can be absorbed by the lye based on the acid-base neutralization reaction and the absorption efficiency can be improved by controlling the inlet pressure and other factors in the biogas purification processing. The experimental results show the purification rules that purification efficiency of biogas is proportional to concentration ratio of methane and carbon dioxide before reaction, inlet pressure, fluid volume of lye, lye concentration and volume of filler, but inversely proportional to the total inlet flow, which builds theoretic foundation for the later design of the biogas purification device.

Abstract The development and utilization of livestock manure biogas technology as an alternative energy source can solve supply problems and contamination of the environment. This study aims to analyze the factors that influence public acceptance of livestock manure biogas technology. It was conducted in Boyolali Regency, with a livestock population of 86,363 dairy and 86,988 beef cattles, hence, the potential for biogas raw materials was high. Moreover, the respondents were 61 people who have used livestock manure biogas, while the method used was descriptive quantitative, with survey data collection techniques. The data were analyzed descriptively along with the multiple linear regression test. The results showed that the acceptance of biogas technology by the community was very high with an average acceptance score of 4.35. Based on the F-test results, the variables of motivation, farmer experience, livestock number, income level, the intensity of counseling, and access to information simultaneously affect biogas acceptance, while the t-test results showed that biogas acceptance is partially influenced by motivational variables, livestock number, intensity of extension, and access to information. Therefore, it was concluded that public acceptance of biogas is influenced by motivational factors, livestock number, intensity of counseling, and access to information.

The use of alternative biomass sources that are not competitive with food production is intended for sustainable management in biogas production through anaerobic digestion. This study investigates the Napier grass and cattle slurry-based biogas production application that could be applied more cost-effectively more sustainable production biogas. The laboratory-based biogas plant and a biogas plant in practice revealed that the results from the laboratory experiments were realistic and transferable into practice. The effect of feedstock screening on the biogas yield of Napier grass and cattle slurry was evaluated in batch digesters under mesophilic conditions. Moreover, highest methane content was reached 64.4%. The biogas from the co-digestion of Napier grass and cow farm slurry containing the higher calorific value was 25.69 MJ/m3, and the lower calorific value was 23.14 MJ/m3 . The results demonstrated that combining Napier grass with common cow farm slurry can accelerate the reaction, increase efficiency, and increase methane content. Therefore, the co-digestion of Napier grass and cow farm slurry was a promising method for increasing biogas production.

Biogas is environmentally sound and economically viable, clean, and renewable energy source. Despite its numerous benefits and dissemination efforts, the adoption of biogas technology has been low. The objective of this study was to assess factors determining adoption of biogas technology as an alternative energy source at household level in Aleta Wondo district, southern Ethiopia. A multistage sampling technique was employed to select sample households. A total of 148 sample households, 51 biogas technology adopters, and 97 nonadopter households were surveyed. The collected data were analyzed by inferential statistics and econometric model using STATA version 13.1. Results from the probit model showed that education level of household head, annual income level, livestock holding size, access to technical support, and level of awareness have significant positive influence on households’ decision to adopt biogas technology. Other factors include poor performance of biogas plants associated to technical problems, and high installation costs unaffordable to the majority of rural population had a negative implication in adoption process. These are also the factors contributing to low adoption. Therefore, raising the population awareness on the benefits of biogas and assigning the biogas technicians who can give immediate maintenance services at “Kebele” level could extend the biogas technology.

Tanzanian Government through its policies in response to energy crisis has been promoting among others, biogas as an alternative source of energy. However, the adoption of biogas technology has been reported to be low or not to the expected levels. This study examines the factors that affect the adoption and Non adoption of Biogas technology as an alternative energy source for rural population in Semi arid areas. Kongwa and Chamwino Districts in Dodoma region were used as case study. Data collection methods employed included interviews, focus group discussions and observation. The findings of the study revealed that there is little or no access to the factors hoped to facilitate adoption of biogas technology which implies weakness in promotion efforts. Little involvement of the Government has underestimated the importance of the biogas technology contributing to low adoption. Other factors include, poor performance of biogas plants associated to technical problems, having a negative implication in adoption process, high installation costs unaffordable to the majority of rural population, unreliable feed stocks and water shortage problems. It is recommended that Government should take intentional efforts to fully involve in promoting biogas technology and ensure the enabling environment for the adoption of the technology.

Biogas technology has the potential to achieve at least eight of the Sustainable Development Goals (SDGs). This study assessed household biogas consumption against firewood and its socioeconomic and environmental impacts with regard to achieving the SDGs in the Iganga District, Uganda. In addition, factors hindering the adoption of biogas technology were assessed. Data were collected from 314 respondents using a questionnaire, interview, and observation. A mixed analytical approach combined descriptive analysis, multivariate analysis of variance and one-way analysis of variance tests to compare the impacts of biogas and firewood use and identify factors hindering the adoption of biogas technology. Results show that biogas consumption contributed to higher socioeconomic, health and environmental benefits than firewood. Biogas positively impacted SDG7, and indirectly, SDGs 2, 3, 5, 6, 8, 9, and 13. An estimated 46.9% of households perceive biogas as a clean fuel. The factors motivating biogas consumption include its smoke-free nature, women and children having more time to engage in other development activities and reduced time spent on cooking. In conclusion, biogas offers higher impacts on SDGs compared to firewood. Reviewing the current national renewable energy promotion frameworks to provide biogas subsidies to households and investors can contribute to increasing biogas consumption in households.

The objective of this study was to assess the challenges of adopting biogas technology among rural households in Zambia. Three hundred and twenty households with and without biodigesters were selected randomly from five provinces in the country for the study. A household survey and qualitative methods such as focus group discussions and key interviews were used to collect information. The results show that firewood and charcoal are the main sources of cooking energy in the study areas despite the enormous potential for the utilization of biogas. The use of biogas technology is in its infancy and few households have adopted the technology. The study found that several challenges or factors were responsible for the low adoption status of biogas technology in the study areas. The main challenges were the high cost of installation of biodigesters; lack or limited access to credit to help meet the costs of construction of biodigesters; inadequate numbers of skilled biodigester technicians; and lack of awareness or limited information on biogas technology. Increasing access to affordable credit, as well as awareness raising on biogas technology among rural households are suggested as some of the ways that will assist to promote the adoption of biogas technology as a sustainable renewable energy source for rural populations in Zambia.

Full textAbstract:
This study investigated the feasibility of converting organic waste into energy using biogas technology to address sanitation problems in peri-urban suburbs of Harare, Zimbabwe.These suburbs with an estimated population of 156.975 are unique in that they are not connected to the Harare main water sewer system. A baseline survey was conducted to determine the quantity of biodegradable human and kitchen waste (N=60). Biodigester sizing and costing was done for various scenarios mainly household standalone, single centralised suburb and combined suburbs centralised biogas models. In addition potential biogas conversion to electricity was done for single centralised suburb and combined suburbs centralised biogas models. This was followed by a cost benefit analysis of employing combined suburbs biogas technology. A combined suburbs centralised biogas model was found to be the most feasible scenario producing 7378 m3 of biogas per day with electricity production capacity of 384 kW .There was a potential of wood savings of 6129 tonnes/year, paraffin savings of 2.556 tonnes/year and greenhouse benefits of 980 tonnes of CO2 equivalent emissions/ year and which would attract U$2940 from carbon credits sales per year. The study recommended the adoption of the biogas technology because of its potential toaddress both economic and sanitation challenges being faced by local authorities in developing countries particularly, improved hygienic conditions, energy supply chronic epidemics and sewerreticulation.

In line with the low-carbon strategy, the EU is expected to be climate-neutral by 2050, which would require a significant increase in renewable energy production. Produced biogas is directly used to produce electricity and heat, or it can be upgraded to reach the “renewable natural gas”, i.e., biomethane. This paper reviews the applied production technology and current state of biogas and biomethane production in Europe. Germany, UK, Italy and France are the leaders in biogas production in Europe. Biogas from AD processes is most represented in total biogas production (84%). Germany is deserving for the majority (52%) of AD biogas in the EU, while landfill gas production is well represented in the UK (43%). Biogas from sewage sludge is poorly presented by less than 5% in total biogas quantities produced in the EU. Biomethane facilities will reach a production of 32 TWh in 2020 in Europe. There are currently 18 countries producing biomethane (Germany and France with highest share). Most of the European plants use agricultural substrate (28%), while the second position refers to energy crop feedstock (25%). Sewage sludge facilities participate with 14% in the EU, mostly applied in Sweden. Membrane separation is the most used upgrading technology, applied at around 35% of biomethane plants. High energy prices today, and even higher in the future, give space for the wider acceptance of biomethane use.

Rural communities require appropriate technology to process livestock waste that has been polluting the environment, particularly water bodies such as rivers. Biogas technology offers a solution by converting waste into renewable energy, namely biogas, which can be utilized for daily needs and high-quality organic fertilizer production. Unfortunately, the biogas reactors currently in use were developed over 50 years ago without significant innovations. Hence, there is a pressing need for a more efficient (affordable and user-friendly) and effective (in terms of performance) biogas reactor technology suitable for rural communities—specifically, the Fiber Reinforced Plastic (FRP) biogas reactor technology. The objective of this endeavor is to create a household-scale prototype FRP biogas reactor, designed according to specific requirements and standardized for widespread use. This prototype will be implemented and tested in the field, allowing for dissemination to a broader audience. For modeling purposes, the FRP reactor design will be applied in a demonstration plot in Sunten Jaya Village, Lembang Subdistrict, West Bandung Regency. The results from the demonstration plot reveal that the produced biogas amounts to 40 L/kg of cow dung.

Hydrogen is expected to become an important fuel in the long-term since in combination with fuel cells it offers the opportunity of an intrinsically clean energy supply. By application of supercritical water gasification (SCWG) concept, sustainable hydrogen can be produced from biomass and waste. The paper offers an overview of some recently published papers dealing with SCWG of model compounds and a summary of the investigations on SCWG of real agricultural and food processing wastes. In the frame of our work an intense research was performed to support analyses of SCWG of glycerol and was supported by the investigation of phase equilibrium for the systems gas/water and gas mixtures/water. When glycerol/water solutions were directly injected in the reactor operating at supercritical conditions, gases with high C2+ were obtained by the reforming in supercritical water unit. To reduce the hydrocarbon concentrations and to obtain a syngas with higher CO/CO2 ratios from a mixture of gases (H2, CO, CO2 and CH4), catalytic reactions at high pressure and temperature were introduced reflecting in an increase of the content of H2 and CO. Solubility measurements were conducted for the binary systems of gas and water at elevated pressures and temperatures.

Full textAbstract:
Malawi has the potential to explore the utilization of biogas technology. The technology has existed in the country for decades. However, the uptake has been lower than expected. Further, there has been a high rate of dis-adoption of the installed systems. To deal with the problem, this study explored the opportunities and barriers to biogas technology to enhance biogas adoption and utilization in Malawi. Qualitative research methods using key informant interviews were employed to collect the data from biogas adopters, dis-adopters, potential adopters, and experts. A total of 22 households and 6 experts were interviewed. The findings of the study show that the country has opportunities for biogas adoption and utilization. The most mentioned opportunities were livestock farming practices, constraints to access to reliable energy sources, associated benefits of biogas technology, and land holding. However, the adoption of the technology has faced several challenges. Commonly cited barriers were the high installation and maintenance costs, inadequate feedstock, inappropriate dissemination approaches, lack of training after installation services and expertise, lack of reliable water sources, absence of ownership, lack of cooperation amongst institutions involved in biogas promotion, lack of a coordinating body for institutions involved in biogas dissemination, lack of standards, and socio-cultural factors. To overcome the challenges, strategies were identified, and these include the provision of incentives, loans and subsidies, provision of technical support services, having demonstration sites, employing suitable dissemination approaches, co-digestion or diversification of raw materials, awareness campaigns, and collaboration amongst sectors involved in biogas dissemination.

India is facing a significant energy crisis due to its rapidly growing population, which is not being met by an equivalent increase in energy supply. According to the US Energy Information Administration, India's electricity consumption is projected to grow by 3.3% annually until 2035. Biogas technology, which converts waste into clean energy, offers a promising solution to this problem and accounts for 9% of global energy consumption. Despite being introduced in 1981, biogas technology's potential in India remains largely untapped, with only 7.34 MWe of off-grid projects generated by 2020. However, Tamil Nadu and Karnataka have significant potential for biogas generation. The National Biogas and Manure Management Program (NBMMP) have installed 5,056,139 biogas plants between 1981-82 and 2020-21, with Maharashtra being the top performer. India's agrarian economy provides ample raw materials for biogas generation, making it a crucial renewable resource for the country's energy crisis. Given the pressing need to address global warming, greenhouse effects, depleting fossil fuels, and pollution, biogas technology is essential for a cleaner, more sustainable future. Focusing on biogas technology can help India meet its increasing energy demands and contribute to a cleaner and more sustainable future. From 2018-19 to 2020-21, the NBMMP received a total allocation of INR 1,439,249,000.

Biogas is a natural gas produced by anaerobic bacteria from processing organic matter and used in energy production. The use of biogas is a green technology that is beneficial to the environment. Biogas technology facilitates the use of animal and plant waste such as cow dung and water hyacinth plants. This study aims to optimize biogas production to achieve optimal biogas volume. Anaerobic Fermentation produces biogas for 21 days. Response Surface Methodology (RSM) with a Central Composite Design (CCD) matrix is used for this optimization. To find the ideal location, the biogas volume data is entered into Minitab. The error value from the optimization results is then computed to verify this optimum location. The optimized biogas produces a volume of 344 mL with an error value of 1.74% at a composition of 0.6089 kg of water hyacinth and 0.6860 kg of cow dung.

Full textAbstract:
In order to realize carbon mitigation and the efficient utilization of waste biogas, the biogas-to-methanol process is an important method. The syngas produced by the conventional biogas reforming technology is rich in CO2 and CO, whereas it is poor in hydrogen. Therefore, additional H2 is introduced into the system to adjusted the syngas ratio, promoting the efficient conversion of the biogas. However, the use of traditional H2 production technologies generally results in considerable carbon emissions. Given these points, low-carbon H2 production technologies, namely methane pyrolysis technology and chemical looping reforming technology, are integrated with the biogas-to-methanol process to enhance carbon conversion, carbon reduction, and cost-saving potentials. Comprehensive technical and economic comparisons of the integrated processes are conducted. The process coupled with chemical looping reforming technology has a higher carbon conversion efficiency (73.52%) and energy efficiency (70.41%), and lower unit carbon emissions (0.73 t CO2/t methanol). Additionally, the process coupled with methane pyrolysis technology has higher product revenue, whereas that including chemical looping reforming technology has a lower net production cost (571.33 USD/t methanol). In summary, the novel chemical looping reforming technology provides a cleaner and more sustainable pathway with which to promote the efficient conversion of biogas into methanol.

Abstract In the field of electric power industry, renewable energy sources, fertilisers, reclamation, and waste management, biomass is widely studied and used. Minerals are present in every step of biogas transformation, but their forms, occurrence, and composition have not been studied yet. However, there is no comprehensive study research that would address the presence of mineral phases in the process of biogas production. This aim of the study is determination of the amount and composition of the mineral phases present in fermentation residues resulting from different production technologies. Digestate mineral composition was analysed using 46 samples from agricultural biogas plants and university testing biogas reactor. The majority of samples contained the amorphous phase. Minority phases consisted of quartz, albite, orthoclase, muscovite, and amphibole. Opal-CT was found in eleven samples (1.26 to 12.1% wt.). The elements present in gas-liquid fluids or in liquids, gases and aerosols within the biogas technology system may create mineral phases, namely the amorphous phase or the crystalline phase under certain conditions. Opal-CT may enter the fermenter as part of plant tissues referred to as phytoliths, or as an unwanted admixture of different origin. It may also originate from the present amorphous SiO2.

This article focuses on the development of a conceptual framework guiding the adoption of biogas technology in selected rural areas of the Limpopo province. The theoretical framing of the study emanated from the critical evaluation of models and work that privileged the technical design and optimisation of a biogas system over the adoption of the technology at the household level. Based on the empirical evidence, and using logistic regression analysis, the study highlighted that determinants of biogas technology adoption in communities are complex, context-dependent and spatially varied. Hence, the policy of biogas adoption should be tailored based on the principle of fit-for-purpose, instead of using existing unimodal approaches for all settings. Based on the findings, the study developed a robust conceptual framework that harnesses the relationships between the influencing variables that can enhance the adoption of biogas technology.

This study examined the adaptation and diffusion of biogas technology in Dar es Salaam, utilizing various data collection methods, including surveys, laboratory analysis, field observations, and interviews. Data collection methods and techniques included lab analysis using American public health association (APHA) standard methods, interviews, questionnaire administration The data analysis was undertaken using statistical package for the social sciences (SPSS) with a sample size comprising 100 community heads from Mburahati, 50 biogas technology adopters, 50 non-adopters, and 16 key informants. The findings disclosed that 40% of respondents learned about biogas technology through their friends and neighbours who had already adopted it, while 6% discovered it through exhibitions. A majority (54%) acquired information from other sources like seminars, biogas researchers, extension officers, and technicians who had adopted the technology. The most influential factor affecting the adoption of biogas technology was the community's income level, accounting for 50.4% of all factors. Inadequate funds were a significant challenge for 75% of respondents, and 64.05% hadn't attended training sessions or seminars related to biogas technology, despite their importance. The study also found that neutral pH levels enhanced anaerobic digestion efficiency, leading to efficient biogas production. Efficiency rates varied among case studies, with the International School of Tanganyika achieving rates between 93.52% and 99.35%, Mburahati DEWATs ranging from 82.15% to 98.24%, and CCBRT ranging from 81.98% to 99.61%. These variations in anaerobic digestion efficiency were likely due to the low solid content in the selected substrates or effluents. In conclusion, the study revealed a low level of biogas technology adoption and diffusion in Dar es Salaam. To enhance this process, the government should review and establish a supportive environment for the advancement of this technology.

The aim of the work is to determine and analyse concentrations of individual biogas components according to the used raw materials based on plant biomass. The measurement is focused on biogas production depending on input raw materials like maize silage, grass haylage and rye grain. The total amount of plant biomass entering the fermenter during the measurement varies at around 40% w/w, the rest is liquid beef manure. The measured values are statistically evaluated and optimised for the subsequent effective operation of the biogas plant. A biogas plant operating on the principle of wet anaerobic fermentation process is used for the measurement. The biogas production takes place during the wet fermentation process in the mesophile operation at an average temperature of 40&deg;C. The technology of the biogas plant is based on the principle of using two fermenters. It follows from the measured results that maize silage with liquid beef manure in the ratio of 40:60 can produce biogas with a high content of methane; this performance is not stable. At this concentration of input raw material, the formation of undesirable high concentrations of hydrogen sulphide occurs as well. It is shown from the results that the process of biogas production is stabilised by the addition of other components of plant biomass like grass haylage and rye grain and a limitation of the formation of hydrogen sulphide occurs. It follows from the results that the maize silage should form about 80% w/w from the total amount of the plant biomass used.

<p>Biogas production process is an alternative method to reduce dependency on non-renewable fossil-based energy consumption and also can reduce greenhouse gases production both domestically and industrially. The existing biogas technology is suitable to be adapted in small-micro-medium enterprises and domestics, specifically for those who raise cattle. The case study was performed by observation of biogas production with various wastes as feed, namely cow dung, quail manure, and wastewater of tofu production. The study conducted via direct interviews with stake holders and visitations to the instalations. Based on our observation, biogas production from cow dung exhibits the shortest retention time compared to the others, aside from the value of C/N ratio of the biogas feedstocks. The presence of biogas production installations are significantly reducing the energy supplies among the users. Beside as biogas product, the instalations also produce solid and liquid fertilizers as by-products and have relatively high economic value. Socio – engineering problems based on the application of biodigester are also studied.</p>

The waste processing and renewable energy are being the issues in the industrial 4.0 era. Kitchen and organic trash in the rural areas will become a disaster if there is no solutions. On the other hand, kitchen and organic waste have a positive side, that they can be converted into biogas which can be converted into electricity. On the Minister of Energy and Mineral Resources Regulation Number 27 of 2014, supports the development of biogas and will buy electricity from the biogas conversion. The potential for biogas that obtained by the organic trash per 1000 people is 7619.8 liters of biogas, it meas that the energy contained is still abundant and the production can still be increased if processed with a modern digester system. This research produces a tool in the form of a portable digester that named GenBIoT (IoT-based Biogas Generator) which can be used by the public to produce biogas that used by home industries or general factories. This research used the research method that similar to System Development Life Cycle (SDLC), this tool is built with several stages starting from planning analysis, designing, functional testing, data analysis and reporting of the results or implementing this tool that can be used as an alternative, as a cheap and easy source energy. This tool is based on the Internet of Things so that this tool can be monitored regarding gas pressure in the reactor, biogas volume and it will detect if there is a biogas leak so it will displayed on the system. To produce the maximum biogas composition, 50% of cow dung is required, 40% of kitchen trash and 10% of water with a ratio of 5: 4: 1 so it will produce 40 kg of biogas with a volume of methane gas (VGM) 0.11 m3 of biogas for cow dung. and 0.04 m3. The third experiment becomes the basis of future biogas production with energy produced from biogas per day of 716.39 Wh
