Biomass is an alternative renewable energy sources that can generates energy almost same as fossil fuel. The depletion sources of fossil fuel had increase the potential use of biomass energy. In Malaysia, rice husk and banana residues are abundantly left and not treated with proper disposal method which later may contribute to environment and health problems. Thus the development of biomass composite briquette made from rice husk and banana residue is one of the potential ways to reduce the problems and hence may contribute the better way to treat the waste by recycling the waste into a form of biomass product. The biomass briquettes are used for thermal applications because it can produce a complete combustion as it has a consistent quality and high burning efficiency. However, the quality of the biomass briquette can be added by application of torrefaction pre-treatment method. Torrefaction is a thermal method that can produce more high quality of the briquette with high calorific value, high fixed carbon content, low volatile matter, and low ash content. This study was conducted to assess the physical and combustion characteristic of the biomass briquette from rice husk and banana residue which was produced through torrefaction process. The biomass briquette, were densified by using hot press machine with temperature of 180°C for about 30 minutes. The briquette produce are 150 μm in particle size with varies in mixing ratio of rice husk to banana residue which are 100:0, 80:20 and 60:40. After the briquetting process, the biomass fuel briquettes have been undergoes parameter testing and the data have been analysed. Result showed the best biomass briquette is developed from torrefied rice husk and banana residue mixed at ratio of 60:40. Moreover, SEM image reveal that torrefaction pre-treatment has shrinkage the fibres size which confirming the thermal stability of the briquette.
