| Abstract | The aims of this research were to produce activated carbon from sugarcane bagasse using carbondioxide as an activating agent for syrup decolorization and to calculate its carbon footprint as analternative waste management method. Sugarcane bagasse was prepared from carbonization process witha nitrogen flow rate of 0.2 L/min at temperatures of 500?C, 550?C, and 600?C for 20, 40, and 60 mins.,respectively. A carbonization condition of 550?C for 40 mins was used to activate the sample withnitrogen and carbon dioxide at a temperature of 800?C. Activation time and ratios between nitrogen andcarbon dioxide were compared to the existing chemical resin method for syrup decolorization. ICUMSAmethod was used at temperatures of 70?C-75?C and a pH of 7. Carbon footprint of 0.5 g activated carbonfor syrup decolorization was 1.51 kgCO2-eq and 66% of carbon footprint value come from utilizationstep. |
