Shortage and limitations in the availability of fossil fuels demand focus on the usage of renewable energy in order to shorten the gap between demand and supply. Replacement of non-renewable resource like fossil fuels with briquette making from farm waste helps to lower carbon footprints. Looking at the abundance of annual farm waste accumulation in Assam, this is essentially an unexplored new horizon of energy industry. Therefore, this study was undertaken to see the prospects of biomass briquette making for commercial purpose. The assessment of thermal efficiency showed that calorific values of briquettes made from different agro wastes ranged from 3370 to 4115 Kcal/kg. The residual ash content ranged between 7 and 8.6% of briquettes’ weights. The benefit cost ratio of 1.80 is indicative of a positive net benefit indicating a better prospect of commercial production of biomass briquettes in Assam.
