Abstract :
More and more in our cities the management of the household wastes and industrial by products pose problems and concerns with multiple scopes: environmental, Hygienic. The use of anaerobic digestion as a tool for processing waste has many advantages: it makes it possible to produce a renewable energy, biogas; avoid the carbon emissions in the atmosphere and the pollution of the environment and improve agricultural soil through fertilizer production. This work, which returns in the frame of the management of the solid waste, concerns the study of the anaerobic digestion of coffee waste with the biogas production as a main objective. Thereby, this same study will lead to the determination of anaerobic potential of this waste. The experimental results obtained show clearly that the anaerobic digestion under mesophilic conditions provides a reliable solution for the treatment of this kind of waste; this is proved by the increasing volume of methane obtained and the high biodegradability of organic matter. The methanogenic potential found is about 233.66 NmLCH_4/g VS and the biodegradability reached 81% under these conditions.
