摘要

This study presents an experimental approach to determine the proximate and mineral composition of selected agricultural crop wastes, focusing on sugarcane and banana residues. Representative samples were collected and subjected to proximate analysis to measure key components, including moisture content, volatile matter, fixed carbon, and ash content. To further assess the mineral composition, AAS was utilized to quantify essential elements such as calcium oxide, magnesium oxide, and potassium oxide. The results revealed that banana crop waste had a higher moisture content (8.2%) than sugarcane crop waste (5.95%), whereas sugarcane waste exhibited greater volatile matter (77.99% vs. 63.89%) and fixed carbon (10.89% vs. 10.49%). The ash content of banana crop waste was notably higher at 17.99%, compared to 7.75% for sugarcane waste. Furthermore, the higher heating values (HHV) for sugarcane and banana wastes were recorded at 19.45 MJ/kg and 13.23 MJ/kg, respectively, aligning closely with reported literature values. This study offers key insights into the energy potential and mineral composition of agricultural residues, reinforcing their viability for bioenergy applications and mineral recovery. Future research could explore advanced pretreatment methods to enhance the bioenergy yield and optimize mineral extraction processes for industrial applications. It provides a foundation for optimizing waste-to-energy technologies for developing countries.
