The study aimed at assessing the feasibility of anaerobic sewage sludge treatment, the generation of renewable energy from the produced biogas as well as the use of the treated sewage sludge as an agricultural fertilizer. The study indicated the best solution to be the use of solar energy to dewater the sewage sludge; the subsequent composting of the sludge; the use of the composted sewage sludge for agricultural purposes; and the parallel generation of solar power via a photovoltaic system. This concept shall be realized in the framework of a pilot project at the wastewater treatment plant (WWTP) in Beni Suef. The pilot experiences shall then serve as a basis for a potential replication of the concept throughout Egypt.
