The effect of biological hyperthermal (80℃) hydrolysis treatment on anaerobic digestion residue was evaluated using thermal digestion residue samples of kitchen waste and paper. Residues of continuous thermal anaerobic digestion were hydrolyzed at 80℃ C for a day and their biogas production volumes were measured by batch analysis. One day of hydrolysis converted 8 to 14% of solid COD to soluble COD, and 6 . 5, 5 . 1, and 3 . 5 m 3 of biogas were produced from one-ton samples of anaerobic digestion residue from kitchen waste, a kitchen waste and paper mixture, and paper, respectively. Assuming a continuous semi-dry treatment process, a hyperthermal hydrolysis treatment will make biogas production 17%, 17 and 16% in the cases of kitchen waste, a kitchen waste and paper mixture, and paper, respectively.
