The purpose of this study is the evaluation of bagasse pith for thermal energy and activated carbon production. To assess the energy production, bulk density, melting point, and heating value were measured. Furthermore, moisture content, ash, volatile compounds, fixed carbon, lignin, and element contents were determined. The average ash and volatile content were measured at 30. 23% and 67. 14%, respectively. The bulk density of the pith powder with 80 meshe particles was determined at 0. 15 g/cm3. Lignin content and melting point of pith is measured as 23. 1%, and 1050 ° C, respectively. Sulfur content as an important term of environmental pollution was determined as 0. 3%. Gross heating value was measured directly by calorimeter bomb as 10. 30 MJ/kg that is lower than bagasse and wood. The activated carbon produced from pyrolysis of bagasse pith was chemically activated with zinc chloride. The chemically activated carbons were characterized by measuring iodine of 504 mg/g, specific surface (BET) of 478 m2/g, and pore diameter of 7. 45 nm. This active carbon is suitable for liquid absorption according to the pore size.
