Objective : This study investigated the potential use of sawdust of Daniellia oliveri (African Copaiba Balsam Tree), Rice husk and Groundnut shells to make briquettes for energy generation. Methodology and Result : Doughnut shaped briquettes were produced from three biomass materials at 15%, 25%, and 35% level of starch binder in binary and tertiary combinations. Density, Shatter index and Combustion properties of the briquettes were investigated. The compressed density of Daniellia oliveri + Groundnut briquettes was highly significant (P<0.01) at 2.32g/cm 3 . The relaxed density was highly significant (P<0.01) among the biomass materials and binder levels. Daniellia + Groundnut briquettes recorded the highest relaxed density of 2.46g/cm 3 at 25% starch binder. Daniellia + Groundnut briquettes recorded the highest shatter resistance of 90.4. The specific heat of combustion of briquettes ranged from 4455.0Kcal/kg to 4734.0Kcal/kg. Conclusion and Application of Results : The relative high heating values of the briquettes biomass materials indicate that they can be a very good alternative source of energy for domestic cooking. It is therefore recommended that sawdust of Daniellia oliveri , Rice husk and Groundnut shells that are usually discarded as waste in Nigeria could be converted to briquettes, which will serve as alternative source of energy for domestic cooking.
