摘要：Biogas is the result of the anaerobic digestion of the or ganic ma tter. In this work, we undertook a series of experiments, to characterize and ferment the various substrates and to produce fla mmable biogas. Waste of internal organs of chicke n me at presents a weak ratio C/N of 2,42 but the potential metha noge ne is most important a mo ng the waste studied with 15,68 m 3 /T. That is because there is a large fraction of lipids (32%) in its dry matter. Waste o f the a nimalery fro m the university is characterized by ratio C/N of 8,21, higher with the presence of sawdusts, which leadsto a methanoge nepotential of 11,52 m 3 /T in the second place. Chicke n meat droppings present a ratio C/N of 3,68 which ma kes it possible to have a potential me thanogenes of 11,24 m3/T. The fish scrap is characterized by the weakest ratio C/N of 1,23 leading to the productio n of the lowest potential methano gene 6,64 m3/T, this result is related to the presence of a large proteinic fraction (70%). This work allowed us to conclude that betwe en 32°C and 45°C the biogas production is correctly conduc ted..The che mical compositions of the wastes studied bring the necessary nutrients; mainly (Zinc, Cuivre, Calcium, Nickel and Potassium) to the anaerobic bacteriadevelopment. At the end of the anaerobicdigestion, the digestat obtained keep all mineral fertilizers which makes it possible to use as an agriculturaloutput. This work opens new horizons towardan alternative of the developme nt in the Moroccans rural area, and at the same ti me proposes a renewable energy allowing a be tter mana ge me nt of orga nic waste, the production of flammable gas and also a fertilizing mud for the a me ndme nt of the grounds. In order to complete this work, other e xperiments are p ut in prospect. They will be devoted to the design and construction of an operational ferme ntor adapted to the Moroccan conditions.
