Disposal of biomass becomes often an environmental issue. A novel method has been developed to convert biomass into solid bio-fuel. Experiments were carried out on preparation of solid fuel pellet from industrial biomass wastes. A maximum calorific value of 22,593KJ/kg has been obtained for the bio-fuel prepared in the present investigation and compared with the fossil fuel coal. The bio-fuel pellets were burnt and the emitted green house gases were critically analyzed.
