The study presented in this paper evaluates biogas production from six organic substrates (slaughterhouse waste, cattle and goat manure, banana peels, and mixtures) under anaerobic conditions in the city of N'Djamena (Chad). The tests, conducted over fifty-eight (58) days, measured the volumes of biogas produced, their gas composition (CH?, CO?, N?, H?S), and changes in physicochemical parameters (pH, temperature). The results show that slaughterhouse waste has the highest production yield, while plant substrates (banana peels) have low production and a highly acidic pH, which is unfavorable for methanization. The results show that slaughterhouse waste is the most effective for biogas production in the Sahelian context, while plant substrates require adjustments (pretreatment, co-digestion). The use of slaughterhouse waste can be a sustainable solution for a country like Chad, which has limited financial resources to provide its population with affordable domestic energy and where the management of slaughterhouse waste poses enormous problems for companies operating in this sector.
