Waste-to-Energy (WTE) is a viable option for Municipal Solid Waste (MSW) management and a renewable energy source. MSW is a chronic problem in Libya and more specifically in Libya Urban areas. The MSW practices in Libya are simply done by collecting the waste and dumping it in open landfill sites. Libya is considering WTE as a potential renewable energy source that can contribute to electricity demand. This research aims to assess potential contribution of WTE facility to meet electricity demand in the Benghazi city and to provide an alternative solution to landfills. Scenario for WTE utilization was developed: Mass Burn the analyses were completed for Benghazi city; with current total population. The results show that Benghazi has the potential to produce about 19 MW of electricity based on incineration scenario the year 2030. These values are based on theoretical ideals and help in identifying the optimal WTE techniques for each city.
