Utilizing waste biomass as a reserve energy source can play an essential role in reducing expanding fossil fuel's environmental impact. This paper presented an analysis of physical, chemical, morphological, calorific values and porosity of biomass from coconut shell waste (CSW) as an alternative for biofuel feedstock. The physical properties of CSW biomass were dominated by volatile matter and fixed carbon content of 73.8 and 22.7 (wt.%, DB), respectively. The calorific value is 20.39 MJ/kg, giving a significant energy effect when the biomass is burned. The chemical properties of CSW biomass were dominated by C and O content of 41.04 and 57.47 (wt.%), respectively, contributing most of the oxygen to the thermal process. However, most elements of chemical properties contributed to the formation of ash in the combustor, including minor and major elements (S, K, Si, Al, P, Cl, Ca, Mg, and Fe). Besides, they had a negative effect in the form of slagging in the combustion residue. The porosity analysis of CSW biomass was 67.30 - 72.92%, which was able to increase the size of char particles during the thermal process. The analysis of physicochemical properties and porosity of CSW biomass confirmed that this material could be beneficial as an alternative energy reserve in the future. © Published under licence by IOP Publishing Ltd.
