A gas flare produced by a landfill in Lake County, Ohio. Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide.
The amount of methane that is produced varies significantly based on composition of the waste. Most of the methane produced in MSW landfills is derived from food waste, composite paper, and corrugated cardboard which comprise 19.4 ± 5.5%, 21.9 ± 5.2%, and 20.9 ± 7.1% respectively on average of MSW landfills in the United States.

Residents can drop off food waste, coffee grounds, paper towels, napkins and other materials at either center to keep them out of the Wake County landfill. To date, the town has collected 80 tons ...
Landfills are also a hotbed for waste, from decomposing vegetable scraps and meat bones to worn household appliances, which produce copious amounts of methane, a greenhouse gas with a warming ...
Our food systems also play an important role in potentially reducing emissions from landfills. The methane budget report found that waste was responsible for nearly a fifth of global methane ...
One of the more fruitful fields of work is food waste—when deposited in landfills, food waste produces the greenhouse gas methane and other toxic compounds that can be dangerous to humans and local ecosystems. [11] Landfill gas utilization and municipal composting can capture and use the organic nutrients. [11]
Methanogenesis can also be beneficially exploited, to treat organic waste, to produce useful compounds, and the methane can be collected and used as biogas, a fuel. [21] It is the primary pathway whereby most organic matter disposed of via landfill is broken down. [ 22 ]
One report found that 58% of methane emissions from landfills come from food waste, a major issue because methane is responsible for about a quarter of global warming and has significantly more ...
