Bio-SRF (Solid Refuse Fuel) pellets was manufactured, in which three types of biomass wastes, i.e., paper sludge, waste coffee ground, and waste wood, were chosen as the raw material and pelletized with several mixing recipes. Physicochemical analysis showed that coffee ground has a high calorific value of 5,800 kcal/kg, which is approximately 50% higher than normal wood. The higher heating value of paper sludge has a wide range from 2,000 to 4,000 kcal/kg according to its generation source company. The more waste coffee ground was used, the weaker strength of the bio-SRF pellet. To manufacture a strong bio-SRF pellet, less than 50% waste coffee ground was desirable in its ingredient recipe. Three types of bio-SRF manufactured with different recipes were co-combusted with a 3~4% mixing ratio of total fuel in a 500 MW commercial pulverized-coal power plant for twelve hours continuously to assess its possibility as a renewable fuel. The data showed that the boiler performance, such as the generated power, carbon residue in bottom ash, and pressure stability in the coal mill, were maintained in the normal state and the air pollutant concentrations, such as NOx, SOx, and dust, in the emission stack were similar to the only coal combustion condition.
