News: Tire Recycling & Pyrolysis

Ash content remains one of the most widely used quality indicators for recovered carbon black (rCB). Recently, research has challenged the assumption that lower ash necessarily means better performance in rubber compounds. Carbonaceous residues formed during tire pyrolysis can dilute the measured ash percentage while adversely affecting the surface properties and reinforcing behavior of the recovered carbon black.

Following its sponsorship of rCB Asia 2026, Gangjin Engineering will join rCB Europe 2026 as a sponsor in Amsterdam this November. The team looks forward to continuing conversations from Asia and meeting others working on pyrolysis and recovered carbon black projects. Based in Korea, Gangjin Engineering designs and supplies equipment and process systems for tire and plastic pyrolysis and downstream recovered carbon black (rCB) processing. For rCB projects, its scope covers the steps from screening and magnetic separation through milling, classification, wet pelletizing, drying, cooling and packing. The starting point for each system is the material to be processed, the capacity needed and the requirements for the finished product.

Enviro reported third-quarter net revenues of SEK 0.02 million, down from SEK 1.6 million in the corresponding period of 2025. The operating loss was SEK 37.3 million compared with SEK 25.7 million a year earlier, while the loss after tax widened to SEK 37.3 million from SEK 25.4 million.

The company says Asian tire and rubber manufacturers are facing increasingly demanding material requirements as vehicle technologies, regulations and sustainability expectations evolve. Birla Carbon identifies electric mobility as one of the drivers increasing the importance of tire wear performance and energy efficiency. Electric vehicles can place different performance demands on tires, encouraging manufacturers to optimize compound formulations for durability, rolling resistance and other application-specific requirements.

Waste Energy said all major components of WE #1 are now in place following completion of the fifth major crane day at the Midland site. The remaining construction work is expected to focus primarily on connecting the system, completing piping and other ground-level mechanical work and preparing the equipment for testing and commissioning.

The second Tyrewise annual report, released on October 21, 2026, covers the first complete 12-month period of collections under New Zealand’s regulated tire stewardship system. Tyrewise Scheme Manager 3R Group said the longer reporting period provides a more complete view of how end-of-life tires move through the national system, from entry into the New Zealand market through collection, transport, processing and final recovery.

One of the applications highlighted by TNU is rubberized asphalt. Incorporating recycled tire rubber into asphalt mixtures can help reduce tire-road noise and improve pavement characteristics. TNU cites the PERSEUS research and development project carried out with Tecnalia, which in 2025 tested recycled-rubber pavements on a section of the AP-8 motorway in Bizkaia.

The framework would seek greater consistency in definitions, storage requirements, transportation, processing and disposal rules across jurisdictions. The Committee heard that differences between state and territory systems create uncertainty for legitimate tire businesses and can provide opportunities for illegal operators to exploit regulatory gaps.

Scandinavian Enviro Systems has resolved on a directed issue of 62.5 million new shares and 2.5 million warrants to Nordic Restructuring and Growth Capital 1 following the first SEK 5 million drawdown under the convertible loan agreement signed in August 2026. NRGC requested conversion of the entire first loan tranche immediately after the funds were disbursed, resulting in the issuance of new Enviro shares at SEK 0.08 per share and repayment of the SEK 5 million loan through set-off. The share issue increases Enviro’s outstanding shares from approximately 1.268 billion to 1.330 billion and results in dilution of about 4.7% for existing shareholders. The accompanying warrants have an exercise price of SEK 0.167 per share and could create an additional dilution of approximately 0.2% if fully exercised. Enviro said the financing arrangement is intended to provide liquidity during its ongoing company reorganization and support continued operations.
