Continental Unveils UltraContact NXT, its Most Sustainable Tyre Series to Date
- By TT News
- June 15, 2023

Continental introduced its most sustainable tyre series to date- the UltraContact NXT, which is made of up to 65 percent renewable, recycled and mass balance certified materials without compromising on maximum safety and performance.
The UltraContact NXT is an extension of Continental’s successful UltraContact family, launched in 2022. These tyres are suitable for electric and combustion engines and will be available for European tyre dealers starting in July.
According to Continental, it is the first tyre company to produce a tyre with maximum sustainable materials and EU tyre-label performance in large-scale production. The UltraContact NXT comes in 19 different sizes and has received the highest rating (“A”) on the EU tyre label for rolling resistance, wet braking, and exterior noise.
Depending on the tyre size, the UltraContact NXT is made from up to 65 percent renewable, recycled, and certified sustainable materials. Renewable materials make up to 32 percent of the tyre, including resins derived from leftover materials from the paper and wood industries. The company also uses silicate from rice husk ash to enhance grip, rolling resistance, and tyre lifespan.
“At Continental, safety, performance, and sustainability go hand in hand. With the UltraContact NXT, we deliver on our ambitious sustainability goals. This development represents a significant leap forward and demonstrates our technological leadership as well as our strong commitment to both sustainability and safety,” says Ferdinand Hoyos, Head of Continental’s Business Area Replacement Tires EMEA. He adds, “With its impressive performance, the UltraContact NXT pushes sustainability to the NXT level.”
Continental incorporates up to five percent recycled materials in the UltraContact NXT, obtained from mechanically processed end-of-life tyres. The company uses its ContiRe.Tex technology, which allows them to recycle between nine and fifteen plastic bottles for each tyre, depending on the tyre size. Additionally, recycled steel is used in the manufacturing process. Continental aims to achieve fully circular tyre production by 2050.
The UltraContact NXT also incorporates up to 28 percent of certified sustainable materials through the ISCC PLUS mass balance approach. These materials include synthetic rubber and carbon black made from biobased, bio-circular, and circular sources. Synthetic rubber is a crucial component in modern tyres, offering specific performance characteristics. Carbon black is used to optimize stability, strength, and durability. The ISCC PLUS certification ensures transparency and traceability in the supply chain, verifying sustainable criteria and certifying the resulting products.
Solvay Accelerates Global Circular Silica Efforts

Solvay is expanding its global circular economy strategy by converting its Asian production of highly dispersible silica (HDS) to use certified circular raw materials. Beginning in 2026, its plants in Qingdao, China, and Gunsan, South Korea, will transition to using ISCC+ certified waste sand. This major initiative is projected to make over half of the region’s HDS output circular, directly aiding tyre makers in their goal of incorporating over 40 percent sustainable materials by 2030.
This transition provides tyre manufacturers with a cost-effective, high-volume circular Zeosil silica that integrates seamlessly into existing processes without the need for reformulation. The move builds on the successful conversion of Solvay’s Livorno, Italy, facility to using rice husk ash and reflects a coordinated, global shift towards circular sourcing. It also supports the broader sustainability goals of Solvay Silica, including the adoption of low-emission technologies like electric furnaces to minimise the carbon footprint of its products worldwide.
By pioneering circular silica from diverse feedstocks and regions, Solvay is fostering more resilient and sustainable supply chains through innovative partnerships across the entire value chain.
An Nuyttens, President of Solvay’s Silica Business unit, said, “Solvay’s circular silica helps improve fuel efficiency and EV range, offers long-lasting wear benefits, improves safety, while advancing sustainability. This is more than innovation - it’s a reinvention of how we source, produce and collaborate across the value chain.”
Sinopec Announces First Tender Offer For Foundation Works At Tianjin Rubber Plant

- September 17, 2025
Following the formal approval of its foundational design, Sinopec has announced the construction of a new green, high-end rubber materials facility in Tianjin, China. The project, which was initially revealed in 2023, represents a total investment of CNY 2.452 billion (approximately USD 344.65 million). Its production output will include 100 kilotonne per annum (ktpa) of solution styrene butadiene rubber and an equal volume of nickel-based butadiene rubber.
Operated by Sinopec’s Beijing Yanshan branch, the venture will be funded through a combination of 70 percent bank loans and 30 percent company capital. The initial construction phase, focused on piling work for processing units, storage areas and auxiliary facilities, is valued at CNY 28 million (approximately USD 3.94 million) and scheduled for completion within 31 days.
This new rubber plant is an integral component of the larger Sinopec Nangang high-end materials industrial cluster, which also features a recently completed 1.2 million tonne-per-year ethylene complex. Encompassing a 277,004 sqm site with a built area of 43,522 sqm, the facility is projected to become operational in 2027.
Elkem Achieves Breakthrough In Mechanical Recycling Of Silicone Rubbers

- September 17, 2025

Elkem ASA, a global leader in advanced silicon-based materials, has announced a significant advancement in silicone sustainability with the successful validation of a new mechanical recycling process for High Consistency Rubbers (HCR). This innovation provides a scalable method for recycling crosslinked HCR waste and reintroducing it into new product formulations. The process achieves re-incorporation rates of over 50 percent while maintaining the excellent mechanical properties required for high-performance applications. This breakthrough demonstrates how material engineering can enable a more circular economy for silicones, helping to reduce waste and the carbon footprint while meeting rising market demand for sustainable solutions.
This mechanical recycling process expands Elkem's comprehensive silicone recycling strategy, which now encompasses both chemical and mechanical pathways. The ability to integrate multiple recycling technologies allows the company to tailor its approach based on the type of waste material, specific carbon reduction goals and the performance needs of the final product.
The development is a key outcome of the open innovation project ‘RENOV’ (Recycling & Reincorporation of Elastomer Materials), focused on creating technologies for recycling and reincorporating crosslinked elastomer waste. The project, supported by the French environment agency ADEME, unites Elkem with industrial partners Hutchinson and Nexans, as well as several CNRS-affiliated laboratories. A primary objective is to evaluate market acceptance and identify the most promising commercial and environmental applications for mechanically recycled HCR.
High Consistency Rubbers are valued for their exceptional strength, thermal stability and electrical insulation properties, making them critical components in industries ranging from electric vehicles and aerospace to medical devices and electronics. Elkem will present samples of the recycled material and detail this new technology at the K 2025 trade fair in Düsseldorf, Germany, from 7–14 October 2025.
Joséphine Munsch, R&T sustainability leader at Elkem, said, “This breakthrough demonstrates the power of purpose-driven innovation aligned with market expectations. After two years of development, we are proud to present a first proof of concept for mechanical recycling of HCR, opening the door to new industrial applications and reinforcing our ambition to leverage pragmatic, science-driven solutions to lead and accelerate the transition to a circular economy for silicones.”
