## 1 Introduction
The authors also focused on the characterization and composition of MSW, including moisture content and calorific value. They found that the moisture content was above 60% on average, and the calorific value was found to be 15.51 MJ/kg. Recoverable electrical energy was approximated as 4.482 MWh/d. Lastly, the authors recommended the appropriate technology to be used for MSW disposal in RCC [9]. [PERSON] et al. considered municipal waste and sugarcane bagasse as renewable energy sources. They conducted a study about the quantity of power that can be harnessed from wastes and bagasse, and compared it with the power demand of RCC in Bangladesh. Possible power production from waste was approximated as 119.8 MWh/d and from bagasse, it was approximated as 544 MWh/d [10]. In 2014, an author investigated the generation, characteristics and management of MSW in RCC of Bangladesh and energy generation by the landfill technique. The energy potential from the landfill gas was estimated to be around 5.3 MW from a steam turbine process [11]. Beside Bangladesh, a number of works have been done worldwide on MSW management. In 2015, researchers obtained waste generation and composition data from selected households from each region in Ghana. The rate of waste generation in Ghana was found to be 0.47 kg/person/d. It was also found that households separated their waste effectively, averaging 80% [12]. In China, researchers launched a program focusing on MSW source-separated collection in eight major cities in 2011. Considering the status of MSW management, source-separated collection was given high priority. It has been encouraged to separate recyclable and kitchen wastes at the source. As stakeholders play an important role in waste management, it was suggested to explain their responsibilities to them clearly [13]. It is clear that, in the last few years, researchers have worked on illustrating waste management systems in different major cities of Bangladesh. A number of works have been done on the waste management scenario in RCC, Bangladesh [7; 14; 15]. Possible energy generation was also estimated by various methods [9; 11; 16; 17]. The main aim of this research is to estimate daily MSW generation in RCC and to estimate electric potential from the generated MSW. This work also suggests a suitable waste management plan. Anaerobic digestion has been suggested for implementation in RCC to reduce waste and convert it into useful energy. Therefore, cost analysis of the anaerobic digestion plant has been provided and the payback period of the proposed plant has been determined. To accomplish the objectives, fifty households of different types were surveyed in this work throughout RCC to analyze the waste generation rate. The analyzed data from the investigated households have been used to estimate overall waste generation per day in RCC. Physical (wet) and chemical (dry) compositions of the collected MSW have been analyzed for a better understanding of MSW characteristics. Finally, the calorific value of the MSW and possible electricity generation have been estimated based on this survey. The present status and future recommendations of MSW management with potential treatment strategies are also suggested in this work. The uniqueness of this work is the execution of a door-to-door survey to get a detailed idea about waste composition and the generation rate throughout the city corporation. The selected families represent approximately all types of families who live in RCC. Therefore, the calculated data can be used to estimate the overall waste generation rate and waste composition of this city with high accuracy.
