Characterization of Biochar Produced from Cassava Stem

This project focuses on the characterization of biochar derived from cassava stem, a sustainable and abundant agricultural waste. The production of biochar through pyrolysis offers a promising solution for waste management, soil improvement, and carbon sequestration. The study aims to evaluate the physicochemical properties of the biochar, including its surface area, porosity, pH, nutrient content, and elemental composition. Analytical techniques such as scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) will be employed to investigate its structural and functional characteristics. Additionally, the research will explore the influence of pyrolysis conditions—temperature, heating rate, and residence time—on biochar quality. The potential application of cassava stem biochar as a soil amendment, its impact on soil fertility, and its role in reducing greenhouse gas emissions will also be investigated. By characterizing the biochar, this project seeks to promote the use of agricultural residues in sustainable practices and contribute to a circular bioeconomy.
