Methane (CH4)
Methane is produced in connection with the digestion and decomposition of organic substances, e.g. manure, wastewater sludge or biodegradable waste. In addition, it is generated in livestock enteric fermentation, which is the largest source of methane emissions in the greenhouse gas inventory. In addition to the above, methane is generated in incomplete combustion and evaporates in the processing, transfer and distribution of natural gas and biogas.
