Abstract Poultry manure is an ammonia-rich substrate that inhibits methanogenesis, causing severe problems to the anaerobic digestion process. In this study, the effect of different natural zeolite concentrations on the mesophilic anaerobic digestion of poultry waste inoculated with well-digested swine manure was investigated. A significant increase in methane production was observed in treatments where zeolite was added, compared to the treatment without zeolite.Methane production in the treatment with 10 g dm-3 of natural zeolite was found to be 109.75% higher compared to the treatment without zeolite addition. The results appear to be influenced by the addition of zeolite, which reduces ammonia toxicity in anaerobic digestion and by the ammonia-tolerant swine inoculum.

The operating temperature and water to poultry waste ratio in anaerobic digestion process are among the factors that affect methane production. Therefore, this paper aimed to investigate the influence of temperature and water to poultry waste ratio on anaerobic digestion of poultry waste. In this study, three different temperatures were used; psychrophilic (25 °C), mesophilic (35 °C) and thermophilic (55 °C), while two different water to poultry waste ratio were examined; 1: 1 and 2: 1 (water: poultry waste). The methane production was the highest at mesophilic temperature followed by psychrophilic and thermophilic temperature with cumulative amount of methane at 14.99 x 10-3 L, 0.62 x 10-3 L and 0.22 x 10-3 L respectively. The highest methane production was observed at the water to poultry waste ratio of 2: 1 followed by ratio 1: 1 with cumulative amount of methane production at 0.11 x 10-3 L and 0.05 x 10-3 L.
