This study explores the physicochemical and structural properties of biochar produced from blended feedstocks, focusing on combinations of oak, pine, and refuse-derived fuel (RDF). Utilizing a downdraft gasifier at 850°C, three biochar samples were prepared: one from 100% oak, a second from a 50:50 oak-pine blend, and a third from a blend of 50% oak, 30% pine, and 20% RDF. Advanced characterization techniques, including SEM, XPS, TGA, and Raman spectroscopy, were employed to analyze the biochar's morphological, chemical, and thermal properties. The results highlight the significant impact of feedstock composition on biochar properties, demonstrating how blending different materials can enhance functionality. This research contributes to sustainable waste management and provides insights into optimizing biochar for applications such as soil amendments and environmental remediation. By bridging the gap in understanding blended feedstock biochar, this study paves the way for more effective and sustainable biochar applications in agriculture and environmental conservation.
