Abstract: 
The study seeks to proffer practical solutions to the sustainable waste management of Acacia mangium leaves (AML) and explore its solid biofuel (SBF) potential through thermochemical valorization. Consequently, the physicochemical, thermal and kinetic properties of AML were examined using elemental, proximate, bomb calorimetric, thermogravimetric (TG-DTG), and Kissinger kinetic analyses. The results revealed AML possesses high content of carbon, volatile matter, and fixed carbon but low moisture and ash content. The heating value of AML was compared to that of A. mangium wood. Furthermore, thermal decomposition was strongly influenced by temperature and heating rate, although results indicate higher temperatures are required for complete conversion of AML. The Kissinger kinetic model revealed activation energy E and frequency factor A for AML. The results indicate AML possesses good SBF qualities for future bioenergy applications.
