Abstract:

Abstract The study assesses the potential of mango endocarps as a renewable bioenergy feedstock, using native varieties of mango in Cambodia. Given growing demand for renewable energy and low utilization levels of agro-residues, mango endocarps are a potential substitute feedstock. The study analyzed a mango endocarp sample comprising of a blend of native Cambodian varieties to establish their physicochemical attributes, calorific value, elemental content, and thermal properties. The samples were dried, and crushed and underwent ultimate and proximate analysis. It had 6.7% moisture content that is ideal in biomass fuel to reduce the process of pre-drying on large scale. It had 1.8% ash content which reduced residue while burning and added efficiency when being burned. The volatile matter had 78.6%, that is the highest energy-releasing capacity. Carbon content of 47.3%, gross calorific value (GCV) and net calorific value (NCV) of 18.36 MJ/kg and 17.13 MJ/kg, respectively, which reflect mango endocarps to be a biomass of high energy content equivalent to wood pellets. Elemental analysis also felt the presence of good combustible contents in terms of calcium (6.4%) and potassium (4.5%), accounting for high combustion properties. Trace metal analysis also revealed zero toxicity emissions with less than 0.20 mg/kg lead and mercury content being 0.002 mg/kg. Thermal decomposition studies also revealed high stability with peak decomposition temperatures ranging from 1030°C to 1390°C, thus accounting for their suitability in high-class thermochemical conversion processes such as pyrolysis and gasification. The findings show that mango endocarps are a viable feedstock for bioenergy production with potential applications in s
