- It is important to install pumps to keep the liquid levels under control
- Ways of converting LFG to energy: electricity generation, direct-use, cogeneration & alternative fuels.
- The gas consists of 50% methane and 50% CO2
- a small amount of non-methane organic compounds
- Landfill gas is created as biological processes decompose the solid waste in a landfill
- Landfill gas collection can be impaired by excessive liquid levels in the collection wells and piping
- High moisture levels in the landfill can increase the generation rate of biologically produced landfill gas
- block off the openings in the collection well screen.
- Landfill gas can become smog, contribute to climate change and odors if it is uncontrolled.
- It can also be captured, converted and used as an energy source
- In the collection well, high liquid levels can impede the flow of gas through the fill itself
- Landfill gas is extracted from landfills using a series of gas collection wells and a vacuum system.
- It directs gas to a central point where it can be processed depending upon the ultimate use for the gas
- There is over 400 LFG energy products in the United States
