In Malaysia, waste paddy plant after rice harvesting were abundant and have no commercial value and significant usage. This paddy waste is commonly burnt on the landfilled which cause open firing and leads to environmental problem. This study determines the potential of rice straw waste for charcoal briquette production and study the effect of using different binders (corn and tapioca starch) in making the briquettes. Raw rice straws were combusted at 260°C for 4 hours in oven to form char powder. Corn starch and tapioca starch used as binder and each of them was mixed with char powder before compacted into briquettes. Each briquette was characterized in terms of their bulk density, moisture content, ash content, compressive strength and flammable characteristics. It was found that corn starch-charcoal briquette showed higher ash content, higher bulk density and compressive strength up to 68 MPa. Increased of both binders has increased the bulk density and compressive strength of briquettes. Both type of charcoal briquettes showed similar ignition time and burning characteristic, approximately at 18 minutes and 0.08 gm/min respectively.
