Cart wizard sticker program

Throughout the summer, staff complete visual assessments of green (organics) and blue (recycling) carts for contamination and materials that don't belong.
Residents either:
- Receive a 'cart wizard' sticker for correctly sorting and placing their cart(s) OR
- Receive an educational orange 'Oops! tag' if additional assistance is needed to understand how to use carts

Oops! tags and contamination

Cart contamination
Contamination are items that do not belong in a particular bin, for example, plastics in the green cart and food waste in the garbage.
Contamination is a concern because it:
- Increases the cost to sort and transport material from the processing facility to the landfill.
- Downgrades the quality of the final recycled product.
- Takes up space in landfills.
- We want to continue to increase our diversion efforts within our City and the current programs are designed to promote diversion.
Oops! tags
If you received an Oops! tag it will explain what went wrong and what needs to be fixed before your next scheduled collection day.
