A product of the degradation of biodegradable waste (any organic matter that can be broken down by micro-organisms such as paper, wood or food stuffs
Collection of gas
- Passive gas collection system
- Active gas collection system
Gas Control
Odor control technologies
- Landfill cover - prevent odors from newly deposited waste or from gases produced during bacterial decomposition
- Flaring - eliminate landfill gas odors by thermally destroying the odor-causing gases
- Venting landfill gas through a filter- Reduce odors by using filter of bacterial slime
Odor Control
Where the odor come from
- Landfill gas
- 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
- Type of waste
- Volume of potentially odorous material
- Time required to unload and cover
- Meteorological and topographic conditions
- Size of working face
- Time of day
Effects of odor
- The sensation of the odor
- The odorant itself.
- The health effects or symptoms vary depending upon the frequency, concentration, and duration of the odor
