Abstract

The potential of inorganic combustible solid waste (ICSW) as sustainable solid fuel regarding its physical and chemical properties have investigated. The physical characterization was obtained by conducting the proximate test using Differential Thermal Analysis (DTA). This ICSW showed excellent physical properties, which its water, volatile, fixed carbon and ash content were 2.25, 65.45, 28.94 and 3.36 (wt%, air dry basis), respectively. The calorific value of 33.87 MJ/kg was found in the ICSW, which it to be comparable to the medium class of bituminous coal. The energy density of ICSW was 3612,8 MJ/m3. The ICSW chemical properties, which analyzed by using energy dispersive X-ray (EDX) spectrometry, indicated that it has a high content of C (79,49 wt%) and relatively small content of incombustible ingredient.
