| Abstract | Cassava is one of the top-five most exported agricultural products of Thailand. Afterharvesting the crop there are an estimated 5.5 million metric tons yearly of cassava stumps left in the field. The farmer generally gets rid of such waste by burning that causes environmental pollution. To solve this problem, a highly efficient, commercial-scale furnace was developed to convert useless cassava stumps into high-value activated carbon. The furnace was run for 30 minutes, operating at a high temperature of about 1,200 ?C with physical activation. The characteristics of the activated carbon from cassava stumps produced by this furnace were studied. The BET surface area value was 110.96 m2/g compared to the Langmuir surface area value of 118.16 m2 /g. The BET value is satisfactory for this burning process. An aromatic hydrocarbon functional group was found in the activated carbon sample using FT-IR spectroscopy. The physical structure of the sample was studied using scanning electron microscopy. The life cycle assessment of this research was assessed based on gate-to-gate boundary production of activated carbon from cassava stumps. Converting cassava stumps into activated carbon will reduce greenhouse gas emissions. The emission factor of the cassava stump furnace is 0.0985 ton CO2eq. |
