What we do

Driving sustainable outcomes for Australia's used tyres is our priority.

We run the national and voluntary Tyre Product Stewardship Scheme (TPSS) to help reduce the environmental, health and safety impacts of tyres which reach their end of life in Australia.

About

Sustainable Outcomes Indicator Program

The Sustainable Outcomes Indicator (SOI) is a transparent, independent 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 SOI?

Sustainable Outcome Indicator

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

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

*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.

 

The SOI program helps to:

  • Recognise and reward high-performing participants
  • Provide clear performance information to customers and stakeholders
  • Encourage continuous improvement across the industry
  • Build trust in the tyre resource recovery and recycling sector

SOI scores are publicly available on the TSA website as part of each recycler and collector’s profile.

What’s new in the 2025 update?

Key changes to the SOI program

In 2025, the SOI framework was refreshed to better reflect:

  • Evolving industry practices and priorities
  • The importance of circular economy outcomes
  • Higher-value recovery and transparency across supply chains

Key updates include:

  • Updated criterion names and focus to reflect the most relevant aspects of best practice
  • A new bonus category recognising nationally operating organisations’ broader contributions
  • Enhanced scoring logic for collectors to factor in downstream outcomes
  • Clearer guidance and expectations for all participants

How the SOI works

SOI Key Criterion

A recycler or collector scores against the below 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 following scores from their main TSA Accredited tyre recycling partner: the first three scores, relating to contribution to Australian markets and a circular economy, and the score for verified overseas destinations for exported material.

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. 

Contribution to Reuse and TDP Consumption in Australia

Measures each facility’s share of all rubber material that stays within Australia for reuse, manufacturing into new products, or other beneficial applications (including domestic energy recovery).

This includes:

  • Whole EOLT (end-of-life tyres) repurposed in approved applications in Australia.
  • TDP (tyre-derived products) sold to secondary manufacturers to produce products for the Australian market, used in another application within Australia, or recovered for domestic energy generation.
  • Whole EOLT or TDP transferred to another facility for further processing into a product used domestically.

Each facility is scored according to its share of total contributions to the Australian domestic market.

Scoring bands:

  • 0% – No contribution
  • <2% – Minimal contribution
  • 2–7% – Moderate contribution
  • 7–15% – High contribution
  • >15% – Very high contribution

This approach ensures the program measures and promotes local reuse and circular economy outcomes across the entire sector.

Proportion of Tyres Managed and Processed Recovered for Beneficial Use

Assesses how much of the material managed by the facility is recovered for beneficial use (not landfilled).
Recognises that while some landfilling may be unavoidable (due to contamination or residual fibre), participants should aim for maximum recovery.

Scoring bands:

  • <50% – Low recovery
  • 50–75% – Basic recovery
  • 75–80% – Good recovery
  • 80–90% – High recovery
  • >90% – Excellent recovery

Facilities sending higher proportions of EOLT and TDP to beneficial recovery receive higher scores.

Achieving Best Material Outcomes in Line with Circular Economy Hierarchy

Focuses on the quality of the final outcomes for materials handled at the facility, in line with circular economy and waste hierarchy principles:

  • Disposal – No processing, or landfilling
  • No Processing – No transformation, direct disposal
  • Export for Energy Recovery – Sending to overseas facilities to use as a fuel
  • Export for Recycling/Reuse – Overseas partners who recycle or reuse
  • Domestic Energy Recovery – Domestic energy-from-waste
  • Domestic Recycling/Reuse – Local processing for new products or direct reuse

Facilities investing in technology and operations that prioritise domestic circular outcomes achieve higher scores.

Compliance with Australian Environmental, Social and Regulatory Standards

Assesses a facility’s compliance with best practice standards, based on TSA’s annual external audit.
Scoring depends on the number of open high-risk and medium-risk audit findings:

  • >3 high-risk findings – Low compliance
  • 1–2 high-risk findings – Moderate compliance
  • No high-risk, >2 medium-risk – Good compliance
  • No high-risk, ≤2 medium-risk – Very good compliance
  • No high/medium risk – Best practice

This ensures participants manage risk and maintain trust in the Scheme.

Verified Overseas Destinations for Exported Material (if applicable)

Recognises the importance of verified overseas markets for exported material.
Scoring is based on the percentage of exported material sent to overseas sites independently verified through the FEMV program or equivalent:

  • 0% – No verified end markets
  • >0–<10% – Minimal verification
  • 10–20% – Moderate verification
  • 20–50% – High verification
  • >50% – Best practice verification

Bonus: National Contribution to Reuse and TDP Consumption

This bonus criterion recognises the broader contribution of nationally operating organisations to reuse and TDP consumption within the state where their facility operates.

It is only applied if it improves the facility’s overall star rating — ensuring that participants are rewarded for these additional efforts without negatively impacting their performance in the core criteria.

Scoring bands:

  • 0% – No contribution
  • >0–<5% – Basic contribution
  • 5–20% – Good contribution
  • 20–50% – High contribution
  • >50% – Outstanding contribution

Best Practice

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.
