Australia has released its first national specification for the use of crumb rubber asphalt on local roads, a move intended to give councils clearer guidance on designing and maintaining light-to-medium-duty networks and to strengthen domestic recycling demand for end-of-life tyres.

The Crumb Rubber Modified Dense Graded Asphalt (CRM DGA) Model Specification for light to medium duty roads was published by the Australian Flexible Pavement Association (AsPA) following collaboration with Tyre Stewardship Australia. The document offers standardised technical requirements for councils, which manage about 75 percent of the national road network — roughly 675,000km of streets and community-level infrastructure.

Existing asphalt standards were largely developed for higher-order state roads, leaving local governments to interpret specifications that did not reflect lower traffic loads or the environmental conditions typical of suburban and regional networks. The new model specification aims to close that gap by setting guidance aligned with the factors that most influence degradation on council roads, such as surface ageing and weather exposure.

The specification promotes the use of crumb rubber modified binders, which can extend pavement life under light-to-medium-duty conditions. Incorporating recycled rubber also aligns with broader circular-economy policies across Australia’s states and municipalities, which are seeking to reduce landfill and illegal dumping while supporting domestic tyre-recycling capacity.

AfPA said the CRM DGA Model Specification V1.0, dated October 2025, is publicly available. It includes requirements for mix design and materials, construction processes such as compaction and temperature control, and performance testing suited to council networks. It also offers practical guidance on integrating reclaimed asphalt pavement content.

Local governments seeking case studies and procurement tools on crumb rubber applications can access Tyre Stewardship Australia’s Crumb Rubber Resource Centre for further technical and project information.

Kraton Corporation, a leading global producer of speciality polymers and high-value bio-based chemicals derived from pine wood pulping co-products, has achieved International Sustainability and Carbon Certification (ISCC) PLUS for its manufacturing facility in Panama City, Florida, United States. This independent certification tracks sustainable materials via a mass balance approach. The achievement allows Kraton to issue a formal ISCC PLUS Sustainability Declaration with shipments of its biobased polyterpene resins, providing its customers with the documentation needed to validate the renewable content in their own products.

The Panama City site becomes the company’s fourth production plant to gain this certification, building upon a commitment that started with the certification of its Sandarne, Sweden, facility in 2021. By securing these certifications across its network, Kraton strengthens its leadership in supplying circular and renewable solutions. This effort supports broader industry shifts, as customers can now more seamlessly integrate verified, sustainable materials into their supply chains and end products.

Ultimately, the company’s pursuit of such certifications aligns with a larger transition towards a more sustainable and circular economy, demonstrating how specialised chemical producers can enable tangible environmental progress through verified chain-of-custody systems.

Lana Culbert, Kraton Pine Chemicals VP of Marketing, said, “Our SYLVARES™ and SYLVATRAXX™ brands feature a portfolio of high-performance polyterpene resins. They are widely recognised for their use in adhesives and tyre applications, yet their versatility extends to other industries, like agriculture, with more opportunities ahead. While we can measure bio-based content of our pine chemicals using Carbon-14 analysis, certifying our Panama City facility under ISCC PLUS strengthens supply chain transparency, supporting the growth of the circular economy.”

Solvay has inaugurated its new bio-circular silica facility at its plant in Livorno, Italy, a strategic investment that underscores Italy’s industrial leadership in green innovation. The facility directly anticipates evolving EU sustainability rules for tyres and supports the ambitious environmental goals of Solvay’s customers. By establishing this operation, Solvay positions itself as a proactive partner in achieving the objectives of the European Green Deal and upcoming product regulations.

The site manufactures highly dispersible silica using an innovative process that transforms rice husk ash, an agricultural byproduct, into a valuable bio-based raw material. This method creates a local circular economy, benefits the agricultural sector, and reduces associated CO₂ emissions by 35 percent compared to conventional production.

This initiative is a cornerstone of Solvay's global strategy to transition all its silica production to certified circular raw materials by 2026. While the Livorno site is the first to use rice husk ash, other global plants will utilise different local waste streams. For the tyre industry, adopting this circular silica already enables tyres to contain up to 15 percent recycled or renewable content, providing significant progress towards the sector’s 2030 material targets.

Beyond compliance, the silica produced is essential for developing energy-efficient tyres that lower rolling resistance, thereby reducing fuel consumption and extending electric vehicle range. The Livorno facility thus reinforces Solvay's market leadership in sustainable silica and highlights Italy’s vital role in the company’s broader portfolio of green investments, including projects in green hydrogen and circular soda ash.

Philippe Kehren, CEO, Solvay, said, “By acting now, Solvay is helping tyre manufacturers prepare for future EU requirements and meet their own sustainability goals. Livorno is a tangible example of how we turn circular economy principles into industrial reality, enabling progress for generations.”

Jana Striezel, Head of Purchasing at Continental Tyres, said, "Solvay has managed to transform an agricultural byproduct into a high-performance material on an industrial scale. We are looking forward to integrating more and more rice husk ash silica as a recycled material in our tyre production and are very satisfied with its performance. We are keen on innovative, renewable and recycled materials because they support our ambitious sustainability roadmap.”

An Nuyttens, President of Solvay’s Silica business, said, “Livorno sets a benchmark for circular innovation in Europe and beyond. Our goal is clear: wherever Solvay produces silica, we will integrate circular materials to reduce environmental impact and support our customers’ sustainability objectives.”

Ecolomondo Corporation, a Canadian developer of sustainable technology for recycling scrap tyres, has announced that its Hawkesbury facility reached a key operational milestone during the week of 12 January 2026, by successfully completing a record five double processing batches. This progress signifies a major step forward as the company advances towards full commercial production at the plant. Utilising its proprietary Thermal Decomposition Process (TDP) and a new automated Human-Machine Interface system, the facility maintained consistent operations and produced high-quality recovered materials.

The week’s activity led to the recycling of an estimated 9,375 scrap tyres, processing a total of 150,000 pounds (approximately 68,038 kg) of rubber feedstock. From this, approximately 60,000 pounds (approximately 27,215 kg) of recovered carbon black and 75,000 pounds (approximately 34,019 kg) of tyre-derived oil were generated, alongside syngas used to power the process itself.

As a Canadian leader in tyre recycling technology, Ecolomondo views these results as a strong validation of the scalability and reliability of its proprietary TDP system, underscoring the ongoing ramp-up at its Hawkesbury TDP facility. This consistent performance enhances the company's position in the circular economy, turning a challenging waste stream into valuable industrial commodities and demonstrating the commercial viability of its innovative approach.
