Which pollutant is most closely associated with methane generation in landfills?

The main idea here is that methane is the gas produced by the anaerobic decay of waste in landfills. In oxygen-poor conditions, microbes break down organic matter and release methane along with some carbon dioxide; methane is the dominant component of typical landfill gas. This makes methane the pollutant most directly linked to the methane-generation process in landfills. Other gases like nitrogen oxides and sulfur dioxide come more from combustion or industrial processes, not from the anaerobic microbial breakdown happening in a landfill, and while carbon dioxide is also produced, the pollutant most specifically associated with this landfill-decomposition gas is methane. Understanding this is why landfill gas capture and methaneRecovery efforts are central to reducing climate impact.
