Don't get STUCK

During winter, the contents of your green cart may freeze to the sides or bottom of the cart. Drivers performing the collection make every effort to dump the entire contents of your green cart, however, if your organics get stuck inside your cart, please be patient and wait until the next organics collection day.

Use these tips to avoid organics freezing to the cart:

  • Wrap food with high moisture content in soiled boxes or newspaper
  • Lining your cart will act as a barrier. Use an acceptable green cart liner such as newspaper, paper bags, soiled pizza boxes, or compostable bags layer wet organics (food waste, leaves) with dry organics (newspaper, pizza boxes)
  • Add crumpled newspaper to the bottom of your cart
  • Don't force the contents of the cart down
  • Strain excess liquid from soups and sauces with a strainer and only place the solid pieces in the cart
  • Store well-wrapped organics waste in the freezer and then place it in your cart on collection day

Check out the Winter green cart tips guide for more information on how to stay unstuck this winter.


Acceptable compostable bags and liners

A liner is not required for use in your kitchen pail however, if you do choose to use a liner you may use:

  • Paper bags
  • Newspaper
  • Compostable bags

Compostable bags are available at most grocery and home hardware retailers in Airdrie. Biodegradable bags are not the same as compostable bags

Compostable bagsBiodegradable or oxo-biodegradable bags
Made from a food by-product such as corn starch and break down into compost Are made from plastic

Are usually opaque and feel softer than plastic bags

Plastic bags prevent the flow of air, which is required during the composting process
Guaranteed to completely break down during the composting process Break apart into small plastic pieces, which do not completely decompose
Have a certified compostable logo Diminishes the quality of the finished compost


If you choose to use a compostable bag, ensure it has one of these symbols:


Pet waste update

In 2017, the City of Calgary will open a state of the art compost facility that will process their green cart material. This in-vessel processing facility will reach temperatures of at least 55 degrees Celsius. This step is important because it kills off pathogens like e-coli and salmonella that might be found in materials like pet waste.

This facility is only accepting material from the City of Calgary. Other municipalities are not able to haul their material there.

Currently, Airdrie takes our green cart material to a facility that uses a windrow process which does not reach the temperatures necessary to break down pathogens. Adding pet waste to our program would compromise the quality of the end product and so we are not able to accept pet waste in our green carts. That being said we recognize the benefit of being able to place pet waste in the organics carts and are looking into other opportunities that may allow us to accept pet waste in the future.
