The increasing energy demand in developing countries necessitates the need to explore renewable energy sources such as biomass briquettes. In this study, bio‐briquettes from biodegradable wastes were developed for sustainable fuel applications. Cylindrical briquettes were fabricated using biochar (160 g) with tapioca starch (16–28 g) and Makoro clay (16–24 g) as the binders. Thermogravimetric analysis (TGA) and bomb calorimetry were utilized to evaluate the physical properties and heating values (HHVs), while durability was assessed via drop tests. Briquettes with tapioca starch exhibited higher HHV (21.9–23.0 MJ/kg) and greater drop strengths (>99%) compared to those with Makoro clay (20.0–22.52 MJ/kg). The energy values were comparable to those of Botswana coal (17.7–23.3 MJ/kg). Optimal ignition and boiling times were observed for briquettes containing 20 g tapioca starch and 20 g Makoro clay. These findings demonstrate the potential of biodegradable waste for producing high‐quality bio‐briquettes, offering a viable renewable energy source while promoting sustainable waste management and reducing greenhouse gas emissions.
