Abstract A consequence of urbanization and rapid economic development is a huge quantity of municipal solid waste (MSW), which could be considered as a promising source for renewable electricity generation. This study was aimed to assess the renewable electricity generation potential in Khuzestan Province from MSW through anaerobic digestion (AD) and gasification technologies. The results showed that Khuzestan Province has the potential to generate approximately 17,678 GW of MSW-based biopower annually. As a result, in addition to earning about 167 thousand USD, around 6.7 thousand tons of CO2eq emission could also be avoided. Also, the GIS-based Fuzzy-AHP method was applied to select the most suitable location to construct MSW power plants. Approximately, 30% of the province’s area is suitable to construct such bio-power plants. The findings provide basic scientific evidence for the government to draw a roadmap toward reducing GHG emissions by converting MSW to renewable electricity in Khuzestan Province.

1 Introduction Population growth, urbanization, industrialization, and economic development have led to a drastic increase in municipal solid waste (MSW) generation [1–3]. It is estimated that the production of global MSW to reach about 2.2 billion tons by the year 2025 [4]. The amount of MSW production in Iran, with a population of about 80 million people and with 74% urbanization, is estimated at 42 thousand tons per day [5, 6]. In the absence of proper management, this type of waste can adversely affect human health and the local environment. On the other hand, fossil fuels are the primary source of electricity in the world, causing a variety of environmental issues. It has been reported that Iranian power sector is responsible for about 30% of the current carbon emission in the country [7]. Therefore, shifting to renewable electricity generation is necessary to meet environmental safety. Recently, waste to energy (WtE) conversion is a very promising approach to dispose MSW in a safe way and achieve economic benefit [8], clean * Seyed Mohammad Safieddin Ardebili [email protected] 1

and sustainable energy, energy security, and environmental sustainability[9, 10]. Therefore, various waste-to-energy technologies are implemented at the industrial scale worldwide, including landfilling with recovery, incineration, and anaerobic digestion (AD). It is estimated that MSW in Iran has the potential to generate approximately 5546 GW per year [5], a great potential to alleviate
