Evaluation of the biogas potential of organic waste in the northern provinces of Morocco

Our work focuses on the promotion and introduction of the biogas technology as innovating solution to manage organic waste and also as a clean and renewable energy. In this article we present the digestible substrate potential in the form of its biogas energy content present in the three regions along the Mediterranean coastline of Morocco, namely de regions of Oriental, Hoceima-Taza-Taounat and Tanger-Tetouan. The organic waste identified are solid manure from animal keeping, the residues of crop growing, industrial organic waste, household organic waste and slaughterhouse waste. The biomass potential from the Oriental region, including the provinces of Oujda, Berkane, Nador, Jerada and Taourirt is about 4.8 million tons a year of which the manure part represents 78 %. This biomass potential can generate theoretically 0,090 Mtep per year of energy in the form of biogas. The biomass potential from the Hoceima- Taza-Taounat region is about 7.8 million tons a year of which 75 % manure, corresponding at 0,130 Mtep of energy per year issued from the biogas produced during the digestion process. The potential in the region of Tanger-Tetouan is about 6.7 million tons a year (81 % manure) representing 0,110 Mtep of biogas energy per year.
