Gases released from municipal waste landfills have the
potential to cause odours in neighbourhoods surrounding the
landfill.
The household and commercial wastes brought to landfills
decompose over time largely through the action of bacteria. This
process produces odorous gases, the amount formed depends upon a
variety of factors: nature and moisture content of the waste,
amount of oxygen present, and temperature inside the landfill.
Less odorous gases can also be generated at landfills due to
chemical reactions and due to the evaporation of chemicals put
into the landfill. Any gases generated tend to rise through the
landfill and reach the air above, although the rate at which
this occurs is affected by landfill content and by the weather.
The amount of gases emitted will vary from landfill to landfill
and will be different for a single landfill at different times
(e.g., due to changing weather, changing landfill content).
Once emitted into the air, landfill gases are carried on surface
level winds. While this dilutes the gases with fresh air, it can
also move them into the community. Naturally, wind speed and
direction determine whether local residents will notice landfill
odours so that the degree of the problem will vary greatly from
day to day.
