Supporting documentation for this table is provided in the 2010 report
available on the CalRecycle website.
The 2008 market size estimates were updated for used tires (combining exported and domestic used tires).
No specific maximum size for the export market is provided. Global waste tire demand far exceeds
California generation.

Landfill uses market size estimate is for landfill gas and leachate recirculation applications only. The 2008
estimate should not be used as a benchmark to evaluate future effort as it was necessarily based on reported
use that in some cases could not be validated by CalRecycle and may not comprise CalRecycle-defined civil
engineering uses. Regardless of the uncertainty, SAIC, Kennec, and CalRecycle agree that market
penetration for landfill use is relatively low and that there is potential for more tire-derived aggregate to go
to landfill gas applications. Landfill applications also include use of significant potential quantities of tire-
derived aggregate in operational layers; however, this use is not listed separately because of significant
regulatory and supply barriers. Despite the barriers, CalRecycle should be open to opportunities to expand
such uses and this potential contributes to listing landfill tire-derived aggregate as a priority market segment.
