Abstract. National primary energy sources currently still rely on fossil fuels, namely petroleum, natural gas and coal. Meanwhile the government policy requires the use of alternative energy to get a bigger portion in the future. One of the new and renewable sources of energy with considerable potential is waste biomass. Waste processing technology that can produce high calorie solid fuels is through the torefaction process. Torefaction is a thermal treatment process of material at temperatures between 200-300°C at atmospheric pressure in absence of oxygen. Torefaction research on several waste components that have been carried out by the researcher team using batch reactors shows that the waste torefaction process can increase the quality of the combustion properties to the coal equivalent. In this study, the waste biomass samples used in the batch reactor that produced high-calorific value torefaction products were re-tested on a lab scale continuous tubular type reactor. The study of waste torefaction using continuous reactors was carried out to investigate the characteristics of solid fuel torefaction products on a larger scale, in preparation for industrial scale production. Tests are carried out with temperature variations of 225, 250, 275, 300 and 325°C. 1 kg biomass feed mass with a residence time of 30 minutes and a cooling time of 5 minutes. The results showed that the waste biomass torefaction process can produce solid fuels with the highest heating value of 5425 kcal/kg, equivalent to subbituminous B coal, which was obtained at an operational temperature of 275°C.
