&description=This period of economic recession and hike in the price of petrol, diesel and electricity in many countries for daily usage have called for alternative fuel source. One of the major driving forces behind this research is the need to address the environmental consequences and health hazards associated with the use of solid fuels such as fuel wood and coal [11] and also to develop an effective means of recycling and managing agro-waste. Therefore in this research work, briquettes of Rice Chaff, Maize Cob and saw dust were produced and evaluated for use. The different briquettes produced were made by blending 120 g of the different Agro-waste each using 20 mL of gelatinous Cassava starch as a binder and Calcium Hydroxide (Ca(OH)<sub>2</sub>), as the desulphurising agent. The Briquettes were produced manually in a calved mold and a G-shaped clamp was used as a press to apply pressure on the compacted Agro-waste in the mold. The result of the proximate analysis indicates that the different briquettes have reasonable calorific value. The Rice Chaff has - Ash content 17.5%, porosity index 94.4%, Burning time 35 minutes, ignition time 30s, Volatile matter 18.6%, moisture content 14.8%. The maize cob has - Ash content 43.2%, Porosity index 91.8%, Burning time 25 minutes, Ignition time 12s, Volatile matter 7.98%, moisture content 6.91%. Finally saw dust has - Ash content 11.6%, porosity index 98.7%, Burning time 8 minutes, Ignition time 9s, Volatile matter 4.23%, moisture content 3.70%. The analysis gave a contrasting combustible quality when the three samples were compared. Based on the above result, use of briquettes like rice chaff, maize cob and saw dust can effectively substitute the existing source of fuel like firewood and petroleum products/electricity because of the reasonable calorific value and other parameters obtained from the proximate analysis.&picture=http://www.aascit.org/aascit/decorators/img/journal/891.jpg)
