Continental is increasing its use of renewable and recycled materials in tyre production, aiming to exceed 40 percent by 2030 while maintaining high safety and performance standards. In 2024, these materials accounted for 26 percent of tyre composition, with a projected 2-3 percent increase in 2025. Key to this shift are carbon black and silica – essential fillers that enhance durability, grip and braking performance.

Silica, a critical component for optimising grip and minimising rolling resistance, is traditionally derived from quartz sand. However, Continental now obtains silica from rice husks, an agricultural by-product of risotto rice production. This innovative approach not only repurposes waste but also requires less energy than conventional methods. Partnering with manufacturers like Solvay in Italy, Continental integrates rice husk-derived silica across its entire tyre portfolio. Silica has been a game-changer in tyre technology for decades, significantly improving safety and energy efficiency. Its use in tread compounds has contributed to a nearly 50 percent reduction in braking distances while also lowering rolling resistance, thereby reducing fuel consumption and CO₂ emissions.

Carbon black, another vital material making up to 20 percent of a passenger car tyre's weight, is being sourced through sustainable alternatives. Continental employs three innovative methods: bio-based carbon black from tall oil (a paper industry by-product), recycled carbon black from pyrolysis oil derived from end-of-life tyres and a direct recovery process that extracts carbon black from used tyres via pyrolysis. The company collaborates with suppliers like Orion Engineered Carbons and Tokai Carbon, utilising different carbon black variants tailored to specific tyre components, such as sidewalls and treads. Through the mass balance approach, Continental substitutes fossil-based raw materials with bio-based or recycled alternatives without altering existing production processes.

Additionally, Continental has partnered with Pyrum Innovations to advance tyre recycling through pyrolysis, a process that recovers carbon black from end-of-life tyres for reuse. While currently applied in forklift tyres, efforts are underway to adapt this recycled carbon black for broader tyre applications, ensuring compliance with performance and safety standards. These initiatives underscore Continental’s dedication to sustainable innovation, demonstrating how eco-friendly materials can enhance both tyre performance and environmental responsibility across the value chain.

Jorge Almeida, head of Sustainability at Continental Tire, said, “Innovation and sustainability go hand in hand at Continental. Using silica from the ashes of rice husks in our tyres shows that we are breaking completely new ground – without compromising on safety, quality or performance.”

In a significant expansion of their existing recycling partnership, Alcoa Australia and Tyrecycle have commenced a new programme to repurpose used conveyor belts from Alcoa’s mining operations. The first reel of used belt was successfully delivered to Tyrecycle’s East Rockingham processing plant, marking a pivotal step in addressing a major waste stream. This initiative builds upon the companies' established contract for recycling off-the-road tyres and forms a core component of Alcoa’s broader corporate strategy to minimise, recycle and reuse waste generated by its Western Australian activities.

The ambitious programme will see approximately 32 kilometres of used conveyor belt transported to the facility over several months. In its initial phase, the collaboration aims to recycle 80 reels of belting. Tyrecycle will process an estimated 100 tonnes of this material weekly, transforming it into rubber crumb. This output will supplement the more than 300 tonnes of Alcoa’s used tyres the company already recycles annually. The primary focus of the recycling process is to reclaim the steel wire embedded within the belts and to convert the rubber into a versatile crumb product.

This crumb is destined for a wide array of practical applications, serving as a valuable additive in road construction bitumen, and as a raw material for creating surfaces for sports fields and playgrounds, adhesives and various moulded rubber goods. Tyrecycle emphasises a circular economy vision, aiming not just for repurposing but for eventually integrating recycled material back into the manufacturing of new conveyor belts. Since its inauguration, the East Rockingham facility has been instrumental in providing Western Australian mining operators with solutions to decarbonise their supply chains. This partnership with Alcoa simultaneously supports regional employment and advances shared environmental goals by diverting substantial rubber waste from landfill and giving it a productive new life.

Ecolomondo Corporation, a Canadian developer of sustainable technology for recycling scrap tyres, is reporting significant commercial progress at its Hawkesbury TDP facility. The company is experiencing a substantial rise in demand for its recycled products, leading to strong sales growth.

A key development involves a major customer who, since mid-July 2025, has purchased 12 truckloads of recovered carbon black (rCB), representing approximately 276 metric tonnes. This client has signalled its intention to increase order volumes further as it transitions its business from another supplier. In another positive step, a second US-based customer has formally approved Ecolomondo's recovered carbon black for use in its manufacturing supply chain and is anticipated to commence bulk orders imminently. Additionally, the company has successfully shipped its 26th tanker of tyre-derived oil, amounting to 520 metric tonnes with an estimated value of USD 416,000.

This upward trend is reflected in the financial results. For the period from 1 January to 31 August 2025, revenues reached USD 640,986, a 91 percent increase compared to the USD 336,078 recorded during the same timeframe in 2024. This growth is largely attributed to the rising sales of recovered carbon black. To support the escalating production needs, Ecolomondo plans to hire and train additional personnel for the Hawkesbury facility. The company notes that, as expected during this operational ramp-up phase, the facility is not yet generating gross margins and continues to operate at a loss.

Jean-François Labbé, Interim CEO, Ecolomondo Corporation, said, “These milestones demonstrate the reliability of our production and the repeated nature of revenues we are building.”
