In present study, the coffee residue was analyzed to finding out physicochemical characteristics and TG analysis that can simulate a pyrolytic kinetic, while comparing with that of chicken residue and food waste. The higher heating value (HHV) of coffee residue was 5,250 kcal/kg that is higher than that of wood pellet (4,300 kcal/kg), Additionally, it showed a good activation energy 72 kJ/mol which is similar with that of other biomass, such as saw dust, wood-chip and so on. It means that the coffee residue is meeting to standard for highest quality of wood pellet, and it would be used as a biomass in the future. However, it never become a fuel without main fuel, such as coal and wood, because its discharge amount is too little. Thus, it has to be applied to existing process, such as power plant which must to meet a RPS regulation. For this, physicochemical characteristics of various biomass have to be analyzed, while considering a discharge amount of them. Therefore, the research result would be provided to reclassification coffee residue to biomass from food wastes in the future.
