This study assesses the technical potential and environmental impacts of domestic biodigesters in the urban commune of Faranah, Republic of Guinea. The main objective is to promote the use and sustainable management of biodigesters with a view to valorizing local biomass for biogas production and environmental protection. The methodology adopted is based on socio-economic surveys, field observations and a sampling of 75 households distributed in 15 enumeration areas, supplemented by interviews with technical services and biogas project focal points. The results show the existence of 15 installed biodigesters, 12 of which are functional, and reveal that 42% of the households surveyed have at least 8 cattle and 3% at least 8 pigs, which constitutes a favorable potential for the supply of biodigesters. The study also highlights that the majority of households still rely on wood and charcoal for cooking, contributing to deforestation and greenhouse gas emissions. The widespread use of biodigesters could reduce pressure on forest resources, improve people's living conditions, and promote a circular and ecological economy adapted to the local context.
