An anaerobic two-stage fermentation process with combined thermophilic hydrogenogenic and methanogenic stages (H_2-CH_4 fermentation process) was applied to artificial food wastes with paper. This report compared the efficiency of the H_2-CH_4 fermentation process and the methane fermentation that lactic fermentation is connected as preprocessing (conventional methane fermentation) by using artificial food wastes with 5% (ratio by wet weight) of paper and without paper as substrates. As a result, for the substrate with paper, an average gasification efficiency of the two-stage fermentation process was 14% higher than that of the conventional fermentation. In an additional experiment in which the proportion of paper increased up to 10% (ratio by wet weight) in dog food was conducted. Although the average gasification efficiency of the H_2-CH_4 fermentation process was slightly decreased according to an increase in the proportion of paper, H_2 and CH_4 production was stable under these experimental conditions.
