Odour Control

Print Link

Today's landfills manage operations to control odours.

Managing odour is a top priority for our landfill operators because we take pride in being a good neighbour. Although things like weather an unplanned maintenance can create challenges in managing odour, we're continually looking for ways to improve.

 

There are typically two sources of odour at a landfill that has to be managed:

  1. Smell of garbage (like in your home garbage can), which can come from trucks hauling waste to the site or when the waste is unloaded.
  2. Landfill gas (sulphur smell), which comes from organic materials decomposing in the landfill.

 

Some things we do to control odours at our landfill in Niagara Falls, Ontario:

  • Do not accept waste with high odour (i.e. no biosolids)
  • Only a small area of the landfill is used each day (called the working face)
  • The waste is covered at the end of each day, typically with soil (called daily cover)
  • Make plans to bury odourous waste immediately when it arrives
  • Properly collect and manage landfill gas, which includes monitoring and adjusting landfill gas wells regularly to optimize gas collection. Landfill gas can be used to generate renewable energy!
  • Host a community response line, where people can contact the company if they sense odours, so employees can find the source of the issue and work to fix it.
