The exploit of biomass for bio-fuel production is becoming trendy as a waste management option. This study is aimed to investigate the physico-chemical and combustion properties of briquettes obtained from pyrolyzed biochar of rice husk. The rice husk biochar briquette bonded with cassava starch as binder were molded and analyzed. Proximate analysis, ultimate analyses, Scanning Electron Microscopy (SEM), FT-IR, calorific values, density and compressive strength, among other properties, were determined for the fabricated briquettes. A high heating value of 39.72 MJ/Kg was recorded for rice husk biochar briquette and 28.45 MJ/Kg of raw rice husk briquette respectively. The ash contents of 3.89 % and 4.52 % were recorded for raw rice husk briquette and rice husk biochar briquette respectively. It took rice husk biochar briquette approximately 13 minutes to boil 1000 cm3 of water, while raw rice husk briquette boiled same quantity of water in 17 minutes. The finding of this study shows that the biochars obtained from the pyrolysis of rice husk are more suitable for fuel briquette production than the raw rice husk.
