Rice Husk Ash Revolution: Continental's Eco-Friendly Tyre Fillers
- By TT News
- July 11, 2025
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.”
Enviro Signs LOI For Pyrolysis Technology Licensing In North America

- March 18, 2026
Scandinavian Enviro Systems AB publ has signed a letter of intent with an undisclosed partner to explore the possibility of licensing its advanced tyre pyrolysis technology for deployment in North America.
The collaboration will focus on conducting a comprehensive feasibility study to evaluate the technical and commercial viability of establishing one or multiple facilities dedicated to processing end-of-life tyres using Enviro’s proprietary method. This study is designed to provide the potential licensee with the necessary insights to assess the prospects of entering into a long-term commercial arrangement and formal technology licensing agreement.
It is important to note that any definitive agreements will depend entirely on the study's outcomes and subsequent negotiations. At this stage, there is no guarantee that the evaluation will lead to binding commitments or that the proposed transaction will ultimately materialise.
Fredrik Aaben, CEO, Scandinavian Enviro Systems, said, “We continue to see strong international interest in Enviro’s technology, and this letter of intent is yet another proof of this.”
Kraton Corporation Announces Price Hike For Polymer Products

- March 17, 2026
Kraton Corporation, a leading global producer of speciality polymers and high-value bio-based chemicals derived from pine wood pulping co-products, a global price increase for all polymer products with effect from 1 April 2026. The price hike will range from USD 440 per MT to USD 700 per MT, or as individual contract terms permit, with the exact price change varying according to the polymer type and production location.
The driving forces behind these significant pricing actions are multifaceted, rooted in substantial disruptions to global supply chains. These disruptions are largely attributed to the ongoing conflict in the Middle East, which has had a cascading effect on logistics. Compounding this issue are the sharply rising costs associated with transportation and essential raw materials.
