Abstract : Waste management is a severe issue in the Kingdom of Saudi Arabia (KSA). Municipalities in Saudi use the landfill to dispose waste, which is the bottom rank in the integrated SWM hierarchy. This research study is about municipal solid waste management (MSWM) in the Eastern Province (EP), the development of a waste-to-energy (WTE) plant, and how the type of municipal solid waste (MSW) in the KSA affects the selection of technologies. A feasibility study was conducted for market analysis, social analysis, economic analysis, and environmental analysis. The market analysis shows that 50.60% of waste generated is food waste, and 17.40% is plastic waste. The case study location was selected from four cities by the weighted scoring method and chosen as Al Rakah Al Shamaliyah City. A pilot study was conducted with EP municipality and the Saudi Council of Engineering (SCE). Eleven responses have been taken into account. Also, an online interview was done with the top management of the EP Amana (waste management department). An online questionnaire was distributed to 379 individuals in Al Shamaliyah City to measure the region's socioeconomic, institutional, and environmental parameters. The results were analyzed using the Statistical Package for the Social Sciences (SPSS) and Microsoft Excel. Following analysis of the pilot study, interview, and questionnaire results, a new and improved WM process plant in Al Rakah Al Shamaliyah was proposed. The importance of this study is that it shows the strength, weakness, and opportunity of MSWM system in KSA. Also, it shows the willingness of residents to participate in the WM process.
