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.

Titan International has introduced the Radial Trail A/T, a new all-terrain high-speed trailer (HST) tyre described as the first true product of its kind in the industry. Unlike conventional trailer tyres that are often adapted from older light truck designs, this model has been engineered entirely from the ground up as a dedicated trailer tyre capable of performing reliably across diverse environments. Alongside this launch, Titan has announced a speed-rating upgrade to its established Radial Trail HD tyre.

The new Radial Trail A/T tyre’s field-tested design incorporates an aggressive tread pattern for enhanced traction on gravel, mud, grass and uneven backroads. The tyre also features a centre tread bridge that lowers rolling resistance to support better fuel efficiency and towing stability. Shoulder tread bridges promote even wear and extend the tyre’s lifespan while reducing road noise, and an open shoulder configuration helps dissipate heat and shed debris. Alternating scoops improve control on soft surfaces such as sand and mud, and extended tread elements along with a rim guard offer added protection against scuffs and impacts. The Radial Trail A/T is currently available in size ST235/75R15 LRE, with four additional sizes expected to roll out over the summer.

Now carrying an N speed rating, which allows for operation at speeds up to 87 mph (approximately 140 kmph), the updated Radial Trail HD tyre incorporates heat-resistant engineering to deliver reliable performance under demanding conditions while surpassing Department of Transportation standards. The enhanced Radial Trail HD tyres are available for order immediately.

Both product releases reflect Titan’s continued focus on advancing trailer tyre technology through purpose-built solutions. Whether used for long highway journeys or off-road exploration, these tyres aim to provide drivers with improved traction, durability, and dependability. Together, they represent the company’s broader effort to support trailer owners with greater confidence and peace of mind on the road.

Ryan Fuller, High Speed Trailer Product Manager, Titan Specialty Division, said, “Titan is setting a new standard in high-speed trailer tyre performance. The Radial Trail A/T is the first trailer tyre truly engineered for all-terrain conditions, not adapted from outdated moulds. Combined with the enhancements to the Radial Trail HD, we’re giving our customers unmatched confidence whether they’re hauling down highways or navigating rugged backroads.”

Continental has once again been recognised as ‘Tire Manufacturer of the Year’ at the latest edition of Tire Technology International Awards for Innovation and Excellence, marking the fifth time it has received this prestigious honour. The independent jury acknowledged the company's groundbreaking tyre technologies, innovative measurement approaches and continuous production process enhancements for establishing new industry standards. Additionally, Continental received the ‘Environmental Achievement of the Year – Manufacturing’ award for its substantial progress in reducing water consumption during tyre production.

During the 3 March ceremony in Hannover, the jury specifically highlighted several key developments from Continental's 2025 initiatives. The company advanced sustainability through the adoption of renewable synthetic rubber components, including pyrolysis oil recovered from end-of-life tyres and recycled cooking oil. A collaborative effort with the Technical University of Braunschweig yielded an innovative method for detecting tyre wear particles using a specialised vacuum system positioned behind drive wheels, equipped with sensitive particle sensors capable of identifying even microscopic airborne debris from various vehicle locations.

The VanContact A/S Eco received special recognition as the first van tyre to achieve the highest ‘A’ rating across all three EU tire label categories – rolling resistance, wet grip and rolling noise. Continental's partnership with the Deutsche Gesellschaft für Internationale Zusammenarbeit promoting responsible natural rubber sourcing in Indonesia also earned jury commendation.

Between 2020 and 2025, Continental successfully reduced water withdrawal per metric tonne of product by over 10 percent across all production facilities, conserving an impressive 197 million litres of water. This achievement resulted from implementing advanced filtration and membrane technologies that enable approximately 90 percent of wastewater to be treated and reused. The company maintains a comprehensive water management approach, systematically refining processes related to heating, cooling and sanitation. External validation of these efforts came through a ‘B’ rating from the independent organisation CDP for Continental's 2025 water management practices.

Edwin Goudswaard, Head of Research and Development at Continental Tires, said, “Tyres are our passion. We are committed to optimising them and making our manufacturing processes even more advanced and resource-efficient. Our greatest strength is our global team, working together closely to develop highly creative and innovative solutions. The jury honoured this very special commitment. And I would like to express my heartfelt thanks to all our colleagues for their remarkable dedication.”

Henning Mühlenstedt, Head of Future Technologies and Sustainable Infrastructure at Continental Tires, said, “Water is a valuable resource. Our continued progress in reducing consumption at our plants demonstrates how effective our approach is.”
