Biogas During storage and when manure has been applied to the land, nitrous oxide is also produced as a byproduct of the denitrification process. Nitrous oxide () is 320 times more aggressive as a greenhouse gas than carbon dioxide and methane 25 times more than carbon dioxide. By converting cow manure into methane biogas via anaerobic digestion, the millions of cattle in the United States would be able to produce 100 billion kiloWatt hours of electricity, enough to power millions of homes across the United States. In fact, one cow can produce enough manure in one day to generate 3 kiloWatt
Nitrous oxide production of nitric acid and adipic acid are the largest sources of nitrous oxide emissions. The adipic acid emissions specifically arise from the degradation of the nitrolic acid intermediate derived from nitration of cyclohexanone. Natural processes that generate nitrous oxide may be classified as nitrification and denitrification. Specifically, they include: These processes are affected by soil chemical and physical properties such as the availability of mineral nitrogen and organic matter, acidity, and soil type; as well as climate-related factors such as soil temperature and water content. The emission of the gas to the atmosphere is limited greatly by its consumption
