In this study, we analyzed the characteristics of municipal waste generated in D Metropolitan City, such as apparent density and physical components. We performed proximate analysis, elemental analysis, and calorific value analysis to improve the SRF conversion efficiency of waste. Representative samples were collected from 11 discrete points in a residential area, a commercial area, a business area, and a landfill site. The average apparent density of all samples was 173.1 kg/m<sup>3</sup>, the moisture content of the three components was 24.0%, the combustible content was 65.3%, and the ash content was 10.7%. In addition, combustible waste accounted for 85.85% of the total waste and non-combustible waste accounted for 14.15% of the total waste. The elemental analysis was carried out on six properties: carbon (C), oxygen (O), hydrogen (H), nitrogen (N), sulfur (S), and chloride (Cl). The ratios of these elements in total waste were highest for carbon (C), hydrogen (H), and oxygen (O). The average total waste lower calorific value was 2,988.36 kcal/kg, and the difference between the higher calorific value and the lower calorific value was approximately 500 kcal/kg (±50).
