The world,Äôs rural population surpasses the three billion people mainly located in Africa and Asia; roughly half the global population lives in the countryside. Access to modern fuels is a challenge for rural people compared to their urban counterparts, which can easily access infrastructures and commercial energy. In developing countries rural populations commonly depend on traditional biomass for cooking and heating. A key strategy in tackling the energy needs of those rural populations is to advance their energy ladder from the inefficient, traditional domestic burn of biomass, organic waste, and animal manure. Governments and non-governmental institutions have supported small biogas digesters in rural areas, mainly in Asia, South America, and Africa, over the last 50¬†years. This chapter reviews the literature to offer an overview of experimental and theoretical evidence regarding the characteristics of design, construction material, feedstock, and operation parameters that made anaerobic digestion in small digesters a valuable source. Small-scale rural biogas digesters can generate environmental, health, and social benefits to rural areas with a net positive impact on energy access. Remarkable improvement in living standards was achieved with small inputs of the methane, produced via anaerobic digestion; however, challenges associated with lack of technical skills, awareness, and education remain and obstruct biogas,Äô full potential in rural areas, mainly in developing countries.

Anaerobic digestion of biomass to biogas, commonly occurring in natural anoxic ecosystems, is an excellent method for utilizing wastes and producing green energy. This book presents examples of local installations of AD, or their proposals, located at small factories, workplaces, and in rural areas and housing complexes. The facilities consider the specific nature of the region, site conditions, and specificity of the utilized wastes. They protect the environment and ensure dispersed energy production. The latter is of great economic significance due to its closeness to end customers. Small local installations expand the pool of renewable energy on a global scale.

Seminar paper from the year 2017 in the subject Energy Sciences, grade: 3.55, , course: Environmental biology, language: English, abstract: This report is based on a literature review to analyze various aspects of biogas technology and address resource requirements and multiple values of biogas technology for rural household in developing countries. Biogas technology has been developed and widely used to produce a renewable, high-quality fuel, biogas. However, the development of biogas technology significantly differs over the world, particularly between developing countries and developed countries. In rural areas of developing countries, biogas is normally used for cooking, lighting, heating, etc, and feedstock for biogas production derives from agricultural resources, such as manure and harvest remains. In addition, biogas technology also contributes to GHGs emission reduction and produces a valuable and improved fertilizer.

The International Conference on the State of the Art on Biogas Technology, Transfer and Diffusion was held in Cairo, Egypt, from 17 to 24 November 1984. The Conference was organized by the Egyptian Academy of Scientific Research and Technology (ASR T), the Egyptian National Research Centre (NRC), the Bioenergy Systems and Technology project (BST) of the US Agency for International Development (US/AID) Office of Energy, and the National Academy of Sciences (NAS). A number of international organizations and agencies co-sponsored the Conference. More than 100 participants from 40 countries attended. The purpose of the Conference was to assess the viability of biogas technology (BGT) and propose future courses of action for exploiting BGT prospects to the fullest extent. The Conference emphasized a balanced coverage of technical, environ mental, social, economic and organizational aspects relevant to biogas systems design, operation and diffusion. It was organized to incorporate experiences that are pertinent, for the most part, to developing countries. In addition to the wide spectrum of presentations and country programs, structured and non-structured discussions among the participants were strongly encouraged in thematic sessions at round-table discussions, and through personal contacts during poster sessions and field trips. It was clear from the enthusiastic response of most participants that the Conference, in large measure, succeeded in fulfilling its mission. Although draft papers were distributed to all participants, it was felt that the results obtained were worthy of organized and refined documentation. And this is precisely what this book intends to do.

Anaerobic digestion (AD) is by far the most important technology for providing clean renewable energy to millions in rural areas of many developing countries. AD of biowastes produces both biomethane and anaerobic digestate as a byproduct that can be used further as a biofertilizer. Biowastes including sewage, food processing wastes, animal wastes, and lignocellulosic wastes typically produce biogas containing 55%–70% biomethane. In the context of energy consumption, more than 85% of the total energy consumed currently comes from non-renewable fossil resources. Biogas technology can provide sustainable, affordable, and eco-friendly energy through waste recycling. This book provides basic knowledge and recent research on biogas production, focusing on the enhancement of biomethane and production routes integrated with microalgae cultivation or agriculture.

Master's Thesis from the year 2018 in the subject Engineering - Civil Engineering, grade: 3.6, Addis Ababa University (Center for Development Studies), course: Environment and Sustainable Development, language: English, abstract: Access to modern energy is a key element in rural development. This thesis identified the Impact of Small Scale Biogas Technology on Household Income and Health in Ada’a Woreda, Oromia Region, Ethiopia. 9 kebeles were purposively selected where there are high number of biogas users. The descriptive statistical significances and the association of the dummy and continuous variables with the dependent variable were tested using chi-square and t-test. Propensity score matching was used to assess the impact small scale biogas technology has on health and income of household. The study found out small scale biogas technology is favorable among users due to; subsidy form the government; relatively cheap comparing to other fuel sources; as it considers the health economic and environmental benefits; as it saves fuel; it being smokeless; its durability; the fact that it cooks quickly; as it effectively uses waste from farm and produces compost for farm use. The result from Propensity score matching indicated that small scale biogas technology has a significant and positive impact on health . So, the impact of small scale biogas technology has an average treatment effect of 8249.2, 5968.5, 9961.5, 8652.3 ETB per annum to household income using nearest neighbor, radius, kernel and stratification methods. The impact of small scale biogas technology on health, the study looked at three outcome variables; cost of the treatment for the victims in the households; the number of days spent for fuel collection per week and; total members of the household affected by indoor air pollution (IAP). The impact of biogas on cost of treatment has an average treatment effect of 320.2, 392.5, 339.2, and 332.8 ETB using nearest neighbor, radius, kernel and stratification methods respectively. The impact of biogas on number days spent for fuel collection has an average treatment effect of -1.5, -1.4, -1.3, and -1.3 days using nearest neighbor, radius, kernel and stratification methods respectively. Lastly the impact of using small scale biogas technology on total members of household that are affected by the illness -1.2, -1.2, -1.2, and -1.2, member using nearest neighbor, radius, kernel and stratification methods respectively. As the technology has a great potential in promoting sustainable and renewable energy, much effort should be done in promoting the technology, awareness raising to non-user household and peer education should be done.
