What is the Sustainable Outcomes Indicator (SOI) program?

The Sustainable Outcomes Indicator (SOI) is a star rating applied to TSA-accredited tyre recycling facilities (recyclers) and collectors. It drives and promotes best practice operations and the development and use of tyre-derived materials and products in the Australian market. SOI has been developed to support the Tyre Product Stewardship Scheme (TPSS) to create long-term sustainable solutions and promote environmentally sound use for end-of-life (EOL) tyres in Australia. 

What is a sustainable outcome indicator?

A sustainable outcome indicator represents the contribution by TSA-accredited recycling facilities and collectors in three key areas:

    • Domestic tyre processing1 industry and market growth
    • Environmentally sound use of EOL tyres supporting circular economy principles
    • Dealing transparently and ethically complying with relevant laws and practices

1 Processing means manual, mechanical (e.g. shredding) or thermal (e.g. pyrolysis) alteration of end-of-life tyres for the purpose of recycling or productive utilisation of EOL tyre material.

How it works

Each TSA-accredited tyre recycler or collector is given a star rating based on scoring against five criteria. Three criteria assess their contribution to the sustainable growth of Australian markets for tyre-derived materials and products. Two criteria assess their level of compliance with environmental, social, and regulatory standards including for their overseas customers (if applicable). 

Each criterion is scored out of five, with the total score determined by the number of criteria the facility is assessed against. The five criteria are: 

A recycler or collector scores against the above criteria result in a star rating. The star rating starts at one star and progresses in half-star increments until it reaches the highest achievable star rating of five.  

Collectors inherit the score for the contribution to the sustainable growth of Australian markets from their main TSA-accredited tyre recycling partner.  

Not all recyclers or collectors will achieve five stars however, all collectors and recyclers should aim to achieve a minimum of a three-star rating. Recyclers and collector's star ratings are updated regularly.

How does SOI drive best practice in Australia?

The SOI program is designed to encourage and support tyre recyclers and collectors to:

  • differentiate their service offering
  • make decisions that improve environmental and compliance outcomes
  • improve industry standards.

It also supports the entire (tyre) value chain, including tyre retailers, local government, and industry to:

  • make informed decisions by choosing a TSA-accredited recycler or collector that aligns with company's environmental social & governance (ESGs) and standards
  • encourage their TSA-accredited recycler or collector to work with TSA to improve their star rating.

Overall, it provides the assurance that brings greater confidence to the entire used tyre resource recovery sector.

It encourages the highest value end use of tyres, which not only meets the Tyre Product Stewardship Scheme’s objectives but also community and government expectations.

It is part of TSA’s broader work to develop Australia’s tyre recycling industry and markets for tyre-derived products, and advance circular economy principles in the sector.
