The Continental tyre plant in Hefei, China, has recently become the company’s latest production site to receive the International Sustainability and Carbon Certification (ISCC) PLUS sustainability certification. 

The globally recognised standard certifies that Continental meets specific sustainability standards. It also confirms the transparency of the traceability of the raw materials used in the production process. Certification of the raw materials enables Continental to ensure the end-to-end traceability of the materials from sustainable sources. For the premium tyre manufacturer, this is a further step on the way to 100 percent sustainable materials in its products by 2050 at the latest.

Jorge Almeida, Head of Sustainability Tires at Continental said, "We are increasing the proportion of renewable and recyclable materials in our tyres. We use the principle of mass balance to enable sustainable materials and technologies to ramp-up, while generating the needed transparency and accountability regarding our progress. This is confirmed by the internationally recognised ISCC PLUS certification. Our aim is to gradually roll out the mass-balance approach to all our tyre plants worldwide."

The company says the certification was based on fulfilling and documenting certain raw material mass balancing procedures. The mass-balance approach mixes fossil, renewable and recycled raw materials in existing systems and processes. The quantities used are tracked along the entire value chain and can therefore be allocated proportionately at any time. The mass-balance approach enables Continental to gradually increase the proportion of sustainable materials in its products. It ensures that the balance of certified sustainable materials can be accurately reported.

Xiaoji Wang, Head of Continental tyre plant in Hefei, China said, "The certification proves the high quality of all of our work processes, from the procurement of certified raw materials to the transportation of the finished tyre. Our Hefei plant meets the strict certification requirements of ISCC PLUS, including raw material traceability and compliance with environmental standards. This certification underlines our commitment to sustainable processes along the entire value chain."

Complete traceability 

ISCC PLUS is an internationally recognised voluntary certification system. It is applicable to the bioeconomy and circular economy and certifies non-conventional raw materials that can be used, for example, in the areas of foodstuffs, animal feed, chemicals, plastics, packaging and textiles. The various criteria required for ISCC PLUS certification include the traceability of raw materials, compliance with environmental standards, the protection of ecosystems, ensuring compliance with labour and human rights and the promotion of sustainable economic development.

The UltraContact NXT the most sustainable serial tyre from Continental, uses mass-balance-certified materials. For example, synthetic rubber made from bio-based and bio-circular raw materials or carbon black, which is produced in part using oil from circular processes. It is manufactured at the tyre plant in Lousado.

Continental says it is working intensively to switch as many raw materials as possible in production to sustainable materials. Raw materials that could be used in tyre production in the future include agricultural waste such as the ash from rice husks, rubber from dandelions, recycled rubber or PET bottles.

The certification of the Continental plants in Hefei, China, and Lousado, Portugal, is an important milestone in Continental’s efforts to use more than 40 percent renewable and recycled materials in its tyres by 2030 and to become completely climate-neutral by 2050. By 2050 at the latest, all new tyres from Continental are to be made entirely from sustainable materials.

Continental’s Hefei tyre plant, located in the Nangang Tech Park of Hefei’s High-Tech Zone, was inaugurated in September 2009 and today covers a total area of 667,000 square meters. The company has been producing tyres for passenger cars and light commercial vehicles for the Chinese market and other markets in the Asia-Pacific region since 2011. The plant has also been producing two-wheel tyres since 2012.

American tyre brand General Tire has released a new all-season tyre aimed at drivers who refuse to compromise between on-road precision and off-road toughness. The Grabber Cross A/S achieves this balance by marrying an unusually stiff tread pattern with a rubber mix explicitly formulated to resist cutting and chunking on harsh terrain.

For drivers who spend time on rocky or uneven terrain, the tyre’s hexagonal tread blocks deliver grip through sharp biting edges, while chamfered groove edges further boost off-road traction. A highly resistant crossover compound protects against tread damage on rough ground. Meanwhile, transverse and longitudinal sipes carved into the blocks provide wet and snowy road grip, and an open shoulder design rapidly channels water away to prevent aquaplaning. On dry roads, internal support elements between the blocks create an extra-stiff tread that distributes pressure evenly, allowing precise steering and sustained high-speed running without sacrificing mileage. Importantly, that stiffness does not come at the cost of comfort, as the tyre also delivers low rolling noise and a smooth ride.

Certified for winter use, the Grabber Cross A/S carries both the M+S marking and the three-peak mountain snowflake symbol, the latter being mandatory in Germany and France since 2024. General Tire offers the model in 44 sizes spanning 16 to 22 inches in diameter, with top speed approvals reaching 240 kmph depending on the size. The tyre fits a broad range of two- and four-wheel-drive vehicles, including popular SUVs such as the VW Tiguan, KIA Sorento, Ford Kuga, Mazda CX 90 and Volvo XC90. An ‘EV Compatible’ sidewall logo also confirms its readiness for electric vehicles.

The Grabber Cross A/S is now reaching dealer shelves and service centres. According to the EU tyre label, this all-season 4x4 tyre earns a rolling resistance rating of C or D, a wet grip score of C and a B classification for rolling noise – positioning it as a versatile option for SUV and EV owners who want one tyre for all seasons.

Matthias Bartz, Business Development Manager for General Tire in Europe, the Middle East and Africa, said, "The Grabber Cross A/S is General Tire's entry into a new product segment. The tyre is designed for high speeds on fast roads but also offers excellent off-road performance in challenging terrain. With our extensive size portfolio, we can offer tyres for about 85 percent of the most popular crossover SUVs.”

Portronics has launched a compact portable tyre inflator named the Vayu Nano, designed specifically to address the space constraints faced by bicycle and motorcycle commuters. Weighing just 185 grammes, the device easily fits into a jacket pocket, small bag or scooter storage compartment. Its matte-black finish and short 7.5-centimetre air hose make it suitable for two-wheelers and minor pressure top-ups rather than inflating car tyres from scratch.

The Vayu Nano delivers up to 120 PSI, sufficient for motorcycles requiring around 45 PSI, bicycles needing approximately 35 PSI and standard sports balls. It can fill a tyre from zero to 35 PSI in under five minutes. A digital display shows pressure in PSI or BAR alongside a battery indicator, while preset modes for various inflatables and a manual custom setting are included. An auto shut-off function stops the device once the target pressure is reached to prevent over-inflation.

Power comes from a dual 600 mAh battery setup with USB-C charging, allowing use with existing phone chargers or power banks. A built-in LED light features an SOS mode for low-light conditions. Priced at INR 4,999, the Vayu Nano is available at a launch price of INR 2,999. It comes with a 12-month warranty and can be purchased through the company’s website or at ecommerce websites and standard offline stores.

Hankook Tire has secured the International Sustainability & Carbon Certification (ISCC) PLUS for its Jiaxing Plant in Zhejiang Province, China. This globally recognised voluntary certification verifies the sustainability of bio-based and recycled materials while ensuring full supply chain transparency. The certification imposes strict verification standards across every stage, from raw material sourcing and manufacturing to the final product output.

The Jiaxing facility’s achievement marks the company’s fourth ISCC PLUS certification. Hankook first earned the distinction for its Geumsan Plant in 2021, becoming the first in the tyre industry to do so. The Rácalmás Plant in Hungary followed in 2023, and the Daejeon Plant received certification in 2025. With this latest addition in China, Hankook has significantly expanded its sustainable manufacturing network across both Asia and Europe.

The Jiaxing Plant has enhanced its production capabilities by increasing the use of sustainable materials and optimising processes. It has established a stable system for products incorporating bio-based and recycled inputs, operating a quality management system based on the mass balance approach. Under its circular economy strategy named E.Circle, Hankook continues to raise the share of sustainable materials. For example, the iON evo tyre, supplied as original equipment for the Porsche Taycan, contains around 45 percent sustainable materials, while the iON GT for the European replacement market has raised that share to up to approximately 77 percent.

Hankook is also applying sustainable materials to tyres used in the FIA World Rally Championship and the ABB FIA Formula E World Championship, reinforcing its technology leadership in global motorsports. Through open innovation with global partners, the company is advancing low-carbon raw materials. Its sustainability efforts have earned it inclusion in the Dow Jones Sustainability Indices World and the highest EcoVadis rating. Looking ahead, Hankook plans to transform the Jiaxing Plant into a key sustainable manufacturing hub in China while continuously upgrading production systems across its global facilities to strengthen supply chain sustainability and ESG competitiveness.
