Sewage potentially contains as much energy as it needs to treat it, however in Lebanon all save one wastewater treatment plant in Tripoli is currently utilizing this fact. Sewage sludge is surplus bacterial biomass from the wastewater treatment process. This sludge is high in moisture content (80-90%), difficult to dry and needs to be disposed of. Anaerobic digestion of sewage sludge offers disposal which produces biogas and fertilizer. A study to assess the techno-economic feasibility of energy production from wastewater treatment plants in Lebanon is underway in coordination with the Ministry of Energy and Water. This study is hoped to set a strategy for this sector, opening the door to new thinking where co-digestion can be targeted to maximize the energy yield of WWTPs.
