Residual waste


Kirkland residents can deposit their polystyrene waste, also known as Plastic #6, at the Municipal Yard from 9 a.m. to 12 noon every Saturday from May to October and from 9 a.m. to 12 noon every first Saturday of the month from November to April.

An employee will be on site to help sort the polystyrene in the three different bins.

Before depositing your polystyrene,
don’t forget to…

  • Remove all labels
  • Take off all adhesive tapes
  • Remove all absorbent pads
  • Clean all containers


1) EPS – Expanded Polystyrene

Large moulded or flat pieces used to prevent fragile items from breaking during transportation (protective packaging). Sanitary or insulated containers used in food service, like coffee cups.

2) XPS – Extruded Polystyrene

Sanitary and insulated food packaging (i.e. meat trays, hinged-lid containers)

3) Hard PS or Non-Expanded Polystyrene

Containers moulded by thermoforming or injection: seedling trays and flower pots, cups and lids, yogurt cups, coffee creamers, injection moulded cups, thermoformed hinged-lid containers (generally clear, such as those used for bakery items), CD/DVD cases.

Polystyrene is recyclable!

Polystyrene, which previously had to be  disposed of in the household garbage collection, is now collected and recycled by the Town of Kirkland.

The collected polystyrene will be recycled and reused in the production of expanded plastic items and/or transformed to be used in the production of hard plastic items.
