How is methane gas produced in a landfill
Web11). Methane production is variable over these five phases and, even within the methanogenic phase, production of methane depends upon the mix of easily digestible biodegradable material versus harder to digest materials such as wood. Some carbon based materials will not decompose and will remain in the landfill. It has been estimated WebComposition of landfill gas produced is 40% to 60% methane and 40% to 60% carbon dioxide (ATSDR, 2001).
