Landfill gas

Landfill gas is a term referring to the gas produced during the decomposition of waste in landfills. It primarily consists of methane, generated by the activities of microorganisms. A key requirement for using landfill gas in combined heat and power plants and stationary gas engines is the purification of the gas from pollutants such as sulfur dioxide and nitrogen oxides. A corresponding gas treatment plant is necessary for this.

Combined heat and power plants (CHP) use the efficiency of gas engines to generate electricity and heat at the same time. This results in a higher efficiency than separate power and heat generation plants. Stationary gas engines are capable of generating electricity from landfill gas. They work on the same principle as a conventional gasoline engine, but landfill gas is used instead of gasoline or diesel.

The use of landfill gas in CHP and stationary gas engines contributes to both energy efficiency and environmental relief. It represents an alternative and renewable energy source and simultaneously reduces greenhouse gas emissions.
