The chart presents results over the last five years. In 2018-19, sales of new tires began to recover from the lower levels seen in the two years prior. Increased sales of new tires results in rebounding recycling volumes as scrap tires are collected and recycled.

Tires are shred into large pieces for use as tire-derived aggregate (TDA). The steel and fibre are still embedded. Application: TDA is applied in place of washed rock (a limited and non-renewable commodity), as drainage material for leachate collection in municipal landfills.
The shred is ground to make mulch, with the steel removed. Application: landscaping.
Tires are processed into crumb with the steel and fibre removed. Application: top-dressing in sports fields or as feedstock for playground surfacing and molded products.
