Rubber certainly has its role to play in forest landscapes across the world, with natural rubber plantations having risen as a substantial basis of deforestation. One element that addresses deforestation concerns is the correct certification of rubber – be it natural or synthetic. International Sustainability & Carbon Certification (ISCC), a globally leading certification system, works with the objective of providing sustainability solutions for fully traceable and deforestation-free supply chains, inter alia involving the rubber industry. ISCC was one of the presenters at the Tire Technology Expo 2022 at Hannover, Germany, and Dr Jan M Henke, Director, ISCC, threw light on the nitty-gritty of certifications in the rubber industry, their clients in the tyre and rubber industry and more, in an interaction with Tyre Trends.

Can you tell us about your global sustainability scheme?
Our global sustainability and carbon certification scheme has certified companies in more than 100 countries. We certify entire supply chains from farms to plantations and forestry, and also the point of origin of waste and residues, biogenic and fossil waste. This is also covering rubber and natural rubber. Moreover, we cover biogenic waste and residues, including fossil waste, like carbon black, which is, again, used in the rubber industry. We also certify pyrolysis, where recycled mixed plastic waste can help produce synthetic rubber out of the pyrolysis oil. And we certify the entire supply chain, sustainability of raw material.

What is Meo’s role?
Meo initiated ISCC in a multi-stakeholder process a long time ago. It once was a Meo project and went on to become an operations and certification scheme. It was even recognised by the European Commission and some other authorities. It later got segregated from Meo, and ISCC is governed by the ISCC Association with more than 200 members.

So, what role does Meo play in this in case of certification?
Certification is always by independent, third-party certification bodies. ISCC is the standard development. Today’s ISCC was once a project of Meo. It then went on to become independent and operational, and was no longer a project but an individual entity running and further developing and improving the certification scheme.

The operations of the certification system, database, registration, qualification, training programme, integrity programme, the website and all the day-to-day business is done by ISCC. We are currently incorporating 45 certification bodies that are actually doing the on-site audits based on the ISCC standard.

Is ISCC recognised by the European Union?
Yes, it is being used in many sectors, like in bio energy, bio fuel, renewable transport fuels etc. In fact, ISCC is also recognised by the European Commission and by companies based on their sustainability standards and different industry initiatives.

Hence, ISCC is active on a really broad scale, covering different types of raw materials, natural rubber being one of them. We are also covering waste and residues for pyrolysis and their outputs. We then go to all the different end markets, which can be polymers, rubber, tyres, packaging, all types of plastic products, bio energy or any type of renewable fuels, aviation fuels, maritime fuels etc. This is global and is being used in more than 100 countries.

Tyre companies are talking about sustainability, but the larger part of the industry is of small stakeholders, especially in the natural rubber segment, where traceability and accountability are the main issues. How do you see this?
That’s a big challenge, especially in rubber production. At the cultivation level, there are a lot of small holders. There also exist large plantations that are easier to implement and certify. However, it’s definitely a bigger challenge with the small holders; it always depends on how well they are organised, whether there are certain structures, cooperatives or some central units.

Can you tell us about the certification of natural rubber?
The certification of natural rubber is definitely possible. Palm oil is maybe another example where the setup is quite similar sometimes. Also, with respect to the small holders, sometimes the companies are the same. Furthermore, we are very active in the palm oil sector with ISCC. We now also see a demand for natural rubber sustainability certification.

Is there a different process for getting certified in the rubber industry or is it a standard process?
It’s a standard process. It works on plantation. In fact, it works more or less the same as for palm plantations. But you certainly need to make sure that all the small holders reach a certain level, which is difficult. So starting out, bigger plantations may be easier because it’s easier for them to properly prepare for the certification audits. And then, you need to involve more farmers, step by step.

Who decides the standard process to get the certifications?
ISCC develops the standards and the requirements in the multi-stakeholder process. It then comes down to a company saying that it wants to become certified, use ISCC and also make certain claims and communications to its customers and stakeholders. They then reach out to a certification body, that is cooperating with ISCC. Following this, the certification body will do the audit on site – the third-party auditor will also make a decision on the issuance of the certificate.

Can tyre manufacturers get different certifications? For instance, one for natural rubber and another one for synthetic rubber? Or do they get one for all?
If tyre manufacturers source raw material for manufacturing from natural rubber but also synthetic rubber and everything under ISCC, then it’s one audit. Then the auditor would look into aspects of the volume of natural rubber being used that has been certified, although upstream. If one buys from certified suppliers and if the same auditors check, then aspects like the share of the certified synthetic rubber being used, the share of carbon black, etc. are taken into account. And finally, everything can be put together and a certain claim can be made.

Can tyre companies get a separate certificate for natural rubber?
Yes, they can. They can have separate certificates for natural and synthetic rubber both, or even of everything together. As for the final tyre, let’s say, if it’s 20 percent natural rubber and 20 percent synthetic rubber (40 percent of the tyre), then they can make certain sustainability claims on use of sustainable, circular materials etc.

What is the value of a certification?
It’s no deforestation – that’s key when it comes to natural rubber. When you certify, ‘no deforestation’ is the core requirement and deforestation is not allowed under ISCC. It is about additional environmental and social human rights criteria. This fits fine in this part of ISCC’s sustainability standard. And then it’s certainly about traceability in the supply chain, all the way in the end to the final tyre. And if this is established, then you can certainly make claims about the rubber or the final tyre, saying that it has been sustainably produced, based on sustainably sourced raw materials etc.

Plus, if you do this in a smart way, then you can actually cover the natural and synthetic rubber. Natural rubber and synthetic rubber are both very important parts of the final tyre. Both can be covered under ISCC.

Deforestation is a big issue, mainly in Southeast Asian and African countries. How difficult is it to keep an eye on that?
It’s not always easy to handle. Deforestation is not allowed under ISCC; there is a cut-off date of January 2008. If there was deforestation after January 2008, one cannot become certified. However, replanting or a change from palm to rubber is not considered as deforestation.

For example, if you have a palm plantation and if you cut it and plant rubber after 25 years, then that’s not deforestation. That’s just normal replanting.

Also, ISCC is certainly doing assessments, supported by remote sensing. Our core principle is no deforestation, which is very important to ISCC and its stakeholders. ISCC is not just us doing the operations in Cologne; there’s the ISCC Association for the multi-stakeholder dialogue. It has over 200 members from entire supply chains, industries, plantation companies, mineral oil, chemical companies, converters etc. We also have research organisations from different regions involved. In fact, also a number of non-governmental organisations are members of the ISCC Association.

The association meets annually and makes important strategic decisions and elects the ISCC Board. Due to the representation of the research sector and non-governmental organisations, there is quite a good balance of what people want and further development.

Can you tell us about the commercial benefits involved in having a certification?
There is a big value in it. It reduces sustainability risks for companies, helps to establish monitoring, protects the license to operate and has commercial value. For example, the OEMs ask for more sustainable products or lower greenhouse gas emissions. They all have climate neutrality commitments in place and need to start delivering step-by-step now; they need to show what are the activities that they are engaged in and how those improve sustainability in the overall supply chain. Here, ISCC certification can be used.

How do you maintain transparency in certification as a third party?
There is an annual audit. The certificate is valid for one year and then there is a re-certification. The company needs to provide evidence in every re-certification that the rules are being followed. And if they are not, a renewal of the certificates is not possible.

We certainly have quality management and training for companies and the auditors as well, who conduct on-site audits. What’s more, we have our own integrity programmes, where we send out our own auditors. These auditors work for ISCC and double-check the performance of the companies and the work of third-party auditors. Therefore, this integrity programme is key. We have the website where all the certificates are being published and the entire standard is public.

Do you help companies improve their sustainability supply chain?
No, we don’t consult. At ISCC, we are not involved in supporting the companies in order to improve. We have the standard and we conduct the training for companies. The preparation for the audit is not where ISCC is involved; it’s independent from that type of work. And the certification bodies are not allowed to consult in parallel either. ISCC is the independent standard that is used to certify that companies fulfil the sustainability requirements.

What are the other segments that you cover in the tyre industry?
It’s the entire supply chain. Petrochemical industries, tyre manufacturers etc. can all be covered. This also includes everything from plantations to the end product in the tyre industry.

Which is the easiest and the toughest one to certify?
All elements of the supply chain need to be covered.

This can sometimes be a challenge in the beginning, so as to convince your suppliers and also get certified. But, in truth, we have more than 6,000 certificates under ISCC. So there are already a lot of players that have valid certificates, and now this is starting to move into the space of rubber and tyre manufacturers.

Can you tell us about your clients in the rubber and tyre industry?
We have requests from many tyre producers right now. Some producers are certified already. Plus, we have requests for carbon black and first requests for natural rubber. We see the number of requests increasing, and we do have first certificates and first registrations from tyre producers. So we expect this to rise further as the industry needs to show compliance with their sustainability and climate neutrality commitments.

We see the entire tyre industry now targeting sustainability. So how do you find more opportunities and what’s your plan to get more client support?
ISCC started to get really further engaged in the rubber and tyre industry about a year ago; the industry has started understanding the standards, participating in ISCC trainings, joining our stakeholder events etc. Therefore, step by step, they got to know ISCC better and what it could do for them. They have now even started to get involved and do certifications, including reaching out all the way to the cultivation of natural rubber.

Are you going to focus on the Asian market?
Yes. In fact, we already have a few hundred certificates in Malaysia, Indonesia and other countries in the region. These markets are truly important. Our other key markets are North America and Europe, while we are also active in Africa and South America.

We are, eventually, trying to do more and convince people to become certified, show compliance to sustainability requirements, engage in a continuous improvement approach to become more sustainable and then allow manufacturers to really make claims.

Mitas, Official Agriculture Tyre Sponsor of the National Tractor Pullers Association (NTPA) and Title Sponsor of the Mitas National Finals Pull-Off, will occupy the spotlight at the Champaign County Fairgrounds in Urbana, Ohio, on 19 September, when the 2026 Grand National titles are decided.

Serving as the closing Grand National fixture of the season, the 39th Mitas All-Star Pull-Off also wraps up the brand's first year as the association's official agricultural tyre partner. That arrangement forms part of a three-season commitment spanning 2026 to 2028, drawing the company nearer to a North American motorsport discipline where immense engine output, grip and staying power face relentless scrutiny with every pass.

Two tyres will illustrate the breadth of the company's agricultural know-how at the venue. The PowerPull 01 30.5L-32 exists purely for pulling competition, arriving as a smooth tyre devoid of any moulded tread so crews can carve bespoke patterns suited to the track and their own machine setup; its tailored compound and tough build supply the grip, endurance and repeatability the sport requires. The VF 750/60R46 CFO 189D HC1000, by contrast, serves high-capacity self-propelled sprayers and comparable field duties, using Very High Flexion engineering to bear heavy loads at lower pressures while a broad contact patch spreads weight and keeps traction. Its tread delivers grip, longevity and self-cleaning ability for dependable service in punishing conditions.

When the 2026 NTPA season reaches its finale in Urbana, the sport's leading pullers and their followers will gather for a fitting celebration. Mitas will be present throughout, tying together the track and the field by demonstrating how the traction, durability and reliability demanded in competition echo the very traits underpinning its agricultural tyre lineup.

Andrea Masella, Marketing Director, Yokohama TWS, said, "Tractor pulling puts enormous demands on every part of the machine, including the tyres, making it a great environment to demonstrate what traction, durability and reliability mean when performance is pushed to the limit. We are proud to support NTPA as its Official Agriculture Tyre Sponsor and to bring our expertise to the Mitas All-Star Pull-Off. This partnership allows us to connect with the pulling community while highlighting the performance focus behind our agricultural tire portfolio. Pull like a Bull — on the track and in the field."

Michelin has introduced an automated regrooving system called NAZCA, aiming to modernise a retreading practice that has served truck, bus and coach tyre maintenance for more than a century. The manual method demands specialised expertise and now confronts ergonomic strain and a shortage of skilled workers. Developed by Michelin engineers, NAZCA automates the process while following manufacturers’ recommendations, targeting consistent quality and repeatability. The system employs a high-density laser scanner and advanced algorithms to exploit every millimetre of usable rubber.

Because each tyre possesses a unique geometry, NAZCA adjusts cut depth in real time across the tyre’s full width and circumference. After more than a year of real-world testing, the machine can raise the number of regrooving jobs a workshop completes. Michelin estimates a capacity increase of 30 percent to 50 percent, depending on operating conditions. Each regrooving operation requires under three minutes of technician hands-on time, allowing staff to handle alignment, repairs and tyre mounting or removal.

This supports greater workshop profitability and flexibility. NAZCA accommodates a wide range of tyre brands and sizes, provided the casing is robust enough for the lifespan-extending procedure. About 20 NAZCA machines are in pilot testing across Europe. Michelin plans further rollouts in various countries in 2027, subject to applicable regulations, with a gradual commercial launch tailored to each market. The system will appear at the Michelin stand during IAA Transportation in Hannover from 14 to 20 September 2026.

NAZCA forms part of Michelin’s multi-life model, pairing regrooving and retreading so a tyre can last up to 2.5 times longer than a single-life product. Regrooving enables use to the legal wear limit, adding up to 25 percent more mileage and up to 5 percent fuel savings. Retreading completes the approach: initial REMIX retreading can double mileage for roughly 60 percent of a new tyre’s cost, while REMIX 2 premium retreading, available for 90 percent of Michelin truck lines, delivers 95 percent of new-tyre performance for about 60 percent of the cost, cutting cost per kilometre by 33 percent. Each retreading also saves about 50 kg of raw materials per tyre.

Pirelli’s Hard tyre played a decisive role as Kimi Antonelli won the inaugural Formula 1 race at the Madring, mastering a one-stop strategy to take victory in the Spanish Grand Prix. The Mercedes driver finished ahead of Max Verstappen and Lando Norris, extending his World Championship lead in the process.

All three podium finishers made their sole pit stop during a Virtual Safety Car period between laps 14 and 15. Antonelli and Norris swapped Pirelli Mediums for Hards, while Verstappen replaced his starting Softs with Hards. The one-stop approach proved dominant across the grid, with only George Russell, Carlos Sainz, Oliver Bearman, Fernando Alonso and Valtteri Bottas stopping twice.

Track temperatures peaked at 52°C and air temperature reached 32°C, mirroring conditions from earlier in the weekend. Russell, Antonelli’s closest title rival and team-mate, came home fifth. Antonelli now leads the standings on 292 points, with Russell second on 211. The Azerbaijan Grand Prix follows on Saturday 26 September.

In supporting action, Dino Beganovic won Sunday’s Formula 2 Feature Race ahead of Alex Dunne and Ritomo Miyata, all three running Softs before Hards and pitting on lap 18. Ugo Ugochukwu secured the Formula 3 World Championship by finishing second in Madrid, as Freddie Slater’s eighth place allowed the title swing. Tuukka Taponen won the finale, with Pedro Clerot third.

Dario Marrafuschi, Pirelli Motorsport Director, said, “The teams approached today's race differently from what had been simulated on track on Friday. Thanks also to the opportunity provided by the Virtual Safety Car, they favoured a more measured management of pace and degradation, which allowed them to significantly extend stint lengths and made the one-stop strategy the preferred choice for the majority of the field. The star of the Grand Prix was the Hard tyre, a compound that had been little explored during free practice and which today demonstrated a very high level of consistency, proving to be the most robust of the three compounds from both a thermal and mechanical perspective. With the C2, we saw several stints exceeding 45 laps, reaching very high levels of wear without any significant performance drop-off. Both the Medium and the Soft also proved to be effective options despite the track temperatures. The C4, in particular, completed competitive stints comparable to those of the Medium in terms of durability.

“As expected, graining appeared mainly on the front-left tyre, on the inner area of the tread, but with limited intensity. The work carried out by the teams on car setup and tyre management helped to minimise its effects. In a race characterised by few overtaking opportunities, the drivers were able to focus on tyre management, contributing to a very straightforward contest from a strategic perspective. Congratulations to Ugo Ugochukwu for securing the Formula 3 championship title today at the end of a highly competitive season. The series continues to represent an important proving ground for young talents from all over the world. The fact that the title was decided only at the final round highlights the exceptionally high level of competitiveness within the championship, which this year delivered spectacular racing and outstanding sporting value.”
