The use of firewood and fossil fuel has led to deforestation and an increase in greenhouse gases which carbon dioxide is considered to be one of the major causes. Thus, this has been responsible for the urgent need for studies on a renewable and sustainable source of fuel energy that can solve this energy problem coupled with the high demand for energy. This research was intended to produce a blend of biomass/coal briquettes that will be utilized for domestic energy. Smokeless briquettes were produced from coal and rice husk under low-pressure densification using a manually fabricated hydraulic jack. The following ratio of coal to rice husks 90:10, 80:20, 70:30, 60:40, 50:50, 40:60, 30:70, 20:80, and 10:90 was produced. Starch was used as the binder, while calcium hydroxide [Ca(OH)2] was used as a fixation agent. Proximate analyses of raw coal and rice husk were carried out. Coal indicated fixed carbon (25.16 %,), volatile matter (58.11 %,) ash content (8.08%), moisture content (8.64 %) and calorific value (24.69MJ/Kg). Rice husk fixed carbon (70.37 %), volatile matter (5.46 %), ash content (16.58 %), moisture content (7.59 %) and calorific value (16.84MJ/Kg). This study indicates that biomass/coal briquettes are potential candidates for domestic energy use.
