Biomass, including livestock excrement, is increasingly being used for energy. Livestock excrement causes problems of air and water pollution. For this reason, the technology of methane fermentation is often used in order to treat it properly and make effective use of it. However, in methane fermentation, the nitrogenous components of the biomass form ammonium ions, which inhibit the fermentation. In order to avoid this problem, we have succeeded in using hydrothermal pretreatment to convert nitrogenous components into ammonium ions before methane fermentation, which are then recovered as ammonia. We have also investigated the reaction rate of nitrogen components in poultry litter.
