What Are the Limitations of the Landfill Gas Control Options?
 Active
- Effectiveness depends on proper placement of system to gas source.
- Improper operation and monitoring potentially creates aerobic conditions
that may lead to piping deformation and subsurface fires.
- Requires monitoring and maintenance.
Passive
- Most effective using shallow trenches.
- Not completely effective for petroleum-based vapors.
Are there any beneficial uses for collected landfill gas?
 Landfill gas is the single largest source of man-made methane
emissions in the United States, contributing to almost 40% of methane
emissions each year (US EPA 1996). Consequently, a growing trend
at landfills across the country is to use recovered methane gas
from landfills as an energy source. Collecting landfill gas for
energyuse greatly reduces the risk of explosions, provides financial
benefits for the community, conserves other energy resources, and
potentially reduces the risk of global climate change.
