Recycling Collection and Processing


Collection of recyclable materials is an integral part of the services provided to property owners in order to reduce the overall amount of waste going to landfill.

Recycling processors in the area take a different mix of materials and in different formats. The City’s current contracted processor has the ability to receive recyclable material in a single stream.  Therefore separating containers, glass and plastics, paper and fibre materials is not required.

There is a possibility that the new contracted processor may or may not be a single stream processor. If that is the case, the separation of items would be required to meet the needs of the processor.
