Methanation of organic waste issued from African university campus in Adrar city (southwestern of Algeria) [Méthanisation des déchets organiques issus de la résidence universitaire de l'université Africaine de la ville d'Adrar Sud-Ouest de l'Algérie]

In this work we are interested in improving the efficiency of biogas production through the use of readily biodegradable substrates. the substrate chosen for this study consists of organic waste,high in sugar and cooked foods rich in starch issued from african university campus in adrar city. in this study we followed the evolution of the ph during anaerobic digestion,biogas production and cod variation. the volume of biogas produced is considerable,it starts with a value of 300 ml / day,with a total volume of 850 ml and a yield of 56.66 ml / g organic matter. the rate of organic matter degradation achieved 76.33% for a short period of eleven days. this allows us to conclude that the chosen substrate is favorable for starting new digesters of various types,for pilot or semi-pilot scale.
