“…Basic sanitation facilities are also not guaranteed in Africa, with 709 million people lacking access to basic sanitation services, and open defecation remains a problem in many areas, such as Burkina Faso, with 9.8 million people affected [29]. In this context, biogas projects offer a promising solution to address the regions' energy and sanitation needs [11]. The anaerobic digestion process generates biogas for electricity generation while also inhibiting potential pathways for the spread of germs from urban waste, especially human feces, and providing basic sanitation services to local communities.…”

“…Studies have shown that the development of renewable energy and modern energy utilization technologies is an effective solution to the problems of climate change, energy stress, and waste management [8][9][10]. Biogas projects, as a form of renewable energy, have great potential in the development of modern energy utilization [11]. The use of effective biogas engineering techniques can minimize the impacts associated with global warming and climate change while improving the human environment [4].…”

More than 500 million people will be added to Africa’s cities by 2040, marking the largest urbanization in history. However, nonrenewable fossil energy sources are inadequate to meet Africa’s energy needs, and their overexploitation leads to intensified global warming. Fortunately, Africa has a huge potential for biomass energy, which will be an important option for combating climate change and energy shortage. In this study, we present a typical large-scale biogas plant in Burkina Faso, West Africa (Ouagadougou Biogas Plant, OUA), which is the first large-scale biogas generation plant in West Africa. The primary objective of OUA is to treat human feces, and it serves as a demonstration plant for generating electricity for feed-in tariffs. The objectives of this study are to assess the greenhouse gas reduction capacity and economic, environmental, and social benefits of OUA and to analyze the opportunities and challenges of developing biogas projects in Africa. As a result, the net economic profit of the OUA biogas plant is approximately USD 305,000 per year, with an anticipated static payback period of 14.5 years. The OUA plant has the capacity to treat 140,000 tons of human feces and 3000 tons of seasonal mixed organic waste annually, effectively reducing greenhouse gas emissions by 5232.61 tCO2eq, improving the habitat, and providing over 30 local jobs. Finally, the development of biogas projects in Africa includes advantages such as suitable natural conditions, the need for social development, and domestic and international support, as well as challenges in terms of national policies, insufficient funding, technical maintenance, and social culture.
