Working To Eliminate Odors At Your Landfill

Landfill Gas

Landfill gas is created by the anaerobic decomposition of waste that is buried in landfills. The composition of landfill gas is dependant on the type of waste but typically is comprised of about 50 % methane and 50 % carbon dioxide, and less than 1 % sulfides.

What causes the odor?

Sulfides are the source of the "rotting" smell often noticed near landfills and can cause unpleasant odors even at very low concentrations. 

Methane and carbon dioxide are odorless. Odors can be destroyed by collecting and flaring the landfill gas. Midshore and the old Easton landfill utilize a system consisting of gas collection wells and thirty-six flares to collect and burn the landfill gas. (See Diagram)

In addition to minimizing odors, burning the gas helps to prevent gas migration and reduce harmful emissions to the atmosphere.  Midshore landfill staff perform daily inspections of all 36 flares to ensure that they are performing properly.

Good Neighbor Policy

Because of the operational nature of landfills, the products they receive and weather variations such as temperature inversions, it is virtually impossible to eliminate all odors. However, MES staff does everything possible, within reason, to make sure that this does not occur.
