Abstract: Anaerobic treatability of municipal landfill leachate was evaluated using lab-scale anaerobic batch reactors. The batch reactor contained two columns. Column 1 consisted of 3 litres of raw leachate and artificial substrate. Column 2 consisted of 3 litres of raw leachate, artificial substrate (mixture of wheat flour and water), and 600 g of deodoriser from the extraction of lemongrass. Before anaerobic digestion occurred, the characteristics parameter of the leachate sample was identified. Then, the process began by adding the artificial substrate into both columns and deodoriser into the column 2. After the anaerobic digestion happened, the biogas was produced. Next, the parameters of the sample were tested again to compare with the initial sample. Data showed that anaerobic digestion could treat the leachate sample and produced the biogas (column 1: 7,550 mg/L and column 2: 7,100 mg/L). The performance of biogas production shows the significant result with present of deodoriser.
