Testing Pilot for Crumb Rubber and Rubber Granules Kicks Off at Tyre Stewardship Australia

Tyre Stewardship Australia is inviting TSA Accredited recyclers to take part in a new pilot program that will test crumb rubber and rubber granules against evolving industry standards.

Participating recyclers will receive:

• TSA-funded lab testing of your crumb rubber and granules, aligned with current market expectations
• A confidential report on your sample data, including a Q&A session to unpack results
• The opportunity to help shape emerging product standards and support broader market uptake

If you’re a TSA Accredited recycler and would like to get involved, please contact us at getonboard@tyrestewardship.org.au

Why This Matters

TSA recently surveyed Australian manufacturers across asphalt, paving, and resin-bound surfaces to better understand their technical requirements when sourcing recycled rubber.

The results confirmed what many in the sector have long understood: crumb rubber is not a generic product, but a precision input.

Key insights included:

• Application-specific granule sizes are essential
• Low contamination levels and consistent grading are critical for safety and quality
• Additional properties like bulk density and shape consistency can influence final product performance

What This Pilot Aims to Do

The new testing program will provide a clearer picture of how crumb rubber produced by TSA Accredited recyclers aligns with industry needs — helping to define specifications, improve consistency, and build greater confidence across markets.

This initiative is part of TSA’s broader effort to drive uptake of tyre-derived products and support a strong, transparent domestic recovery sector.
