Mitigation technologies and practices for reducing CH4 emissions from animal manure management


For manure management sector, CH4 was produced when the organic matter in the manure was anaerobically decomposed by the methanogens. Therefore, CH4 emission can be happened during the whole manure management chain (MMC), from manure excreted, and the following manure storage and treatment sector, and even in the land application sector when the anaerobically condition provided. Based on the literature review for the CH4 mitigation options used in the major animal categories, including pig, dairy, beef cattle and poultry (Table 1-4), the mitigation technologies, practices and the possible integrated mitigation technologies were summarized, and the best technology recommended for each stage was also summarized (Table 5). Meanwhile, the possible effects of the technologies on N2O and NH3 emissions were also evaluated simultaneously.
