The Moulay Abdalah landfill in Morocco generates leachate, a pollutant that poses a significant environmental threat. This study focused on characterizing the biogas produced from the anaerobic digestion of leachate from this landfill and assessing its potential for energy recovery. The research involved collecting leachate directly from the area of the landfill where household waste is compacted. This leachate was subjected to anaerobic digestion in two airtight digesters, each with a volume of 144 m³. The resulting biogas was analyzed to determine its composition of methane (CH₄), carbon dioxide (CO₂), and hydrogen sulfide (H₂S). The results revealed the presence of methanogenic and sulfate-reducing bacteria in the digested leachate, as evidenced by the methane and hydrogen sulfide content in the biogas, respectively. However, the composition of the biogas was found to be unsuitable for energy recovery. The methane content, the primary energy component of biogas, was less than 50%, while the standards for injection into the natural gas grid require a methane content between 55 and 75% (INERIS). The high concentration of hydrogen sulfide also hindered the energy recovery of the biogas. This study focused on a single site, and the results obtained may not be generalizable to other landfills. Additionally, the long-term impact of operating conditions on digester performance was not evaluated. The results of this study highlight the need for additional treatments to improve the quality of the biogas produced and make it suitable for energy recovery.
