Collection of gas

  1. Passive gas collection system
  1. Active gas collection system

Gas Control

Odor control technologies

  1. Landfill cover - prevent odors from newly deposited waste or from gases produced during bacterial decomposition
  1. Flaring - eliminate landfill gas odors by thermally destroying the odor-causing gases
  1. Venting landfill gas through a filter- Reduce odors by using filter of bacterial slime

Odor Control

Where the odor come from

  1. Landfill gas
  1. Leachate
  • produces from organic material that decomposed anaerobically.
  • Made up primarily of methane and carbon dioxide
  • LFG can also transport landfill odors offsite if vented to the atmosphere

Factors influencing odor strength

  1. Type of waste
  1. Volume of potentially odorous material
  1. Time required to unload and cover
  1. Meteorological and topographic conditions
  1. Size of working face
  1. Time of day

Effects of odor

  1. The sensation of the odor
  1. The odorant itself.
  1. The health effects or symptoms vary depending upon the frequency, concentration, and duration of the odor
