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.

Tyres Europe and the Association of Synthetic Amorphous Silica Producers (ASASP) have released a joint position paper on synthetic amorphous silica (SAS) in tyre manufacturing. The document highlights SAS as a critical component that improves wet grip, reduces rolling resistance and supports durability, thereby enhancing vehicle safety, fuel efficiency, electric vehicle range and lowering use-phase emissions.

A proposed harmonised classification for SAS is under consideration. Though not an outright ban, the industry warns it would likely compel manufacturers to phase out SAS during design rather than manage exposure, effectively bypassing practical risk controls.

Tyres Europe and ASASP urge regulators to base any action on robust evaluation of SAS properties, exposure conditions, established industrial uses and broader socio-economic impacts on European value chains. Policy measures must reflect these factors to avoid unintended disruptions.

Tegeta Green Planet participated in the recent Social Design Days conference, a three-day event hosted by the Design Institute that centred on circular design and sustainable innovation. The gathering brought together diverse professionals to explore the intersection of creative disciplines and environmental responsibility.

During the proceedings, Tegeta Green Planet Director Shalva Akhvlediani engaged in a panel discussion that examined Georgia’s trajectory in building a circular economy. The conversation addressed the nation’s current obstacles and prospective avenues for growth, with a particular focus on systemic shifts in resource management and regulatory frameworks.

Akhvlediani pointed to measurable advancements in Georgia’s waste management infrastructure, the adoption of Extended Producer Responsibility standards and a growing national recycling ethos. These developments, he observed, are creating a robust base for more judicious resource utilisation and fostering habits of conscientious consumption. The panel further acknowledged that resourcefulness is deeply rooted in Georgian heritage, where mending, reusing and bequeathing goods were traditional practices, though modern consumerism has eroded these customs, necessitating a blend of age-old wisdom with contemporary circular strategies.

A critical takeaway from the discussion was the assertion that technological fixes and legislation alone are insufficient. Genuine progress, Akhvlediani argued, hinges on synergistic cooperation between designers, architects, researchers and creatives to engineer products and systems that prioritise longevity and recyclability from inception. Social Design Days proved instrumental in facilitating cross-sectoral dialogue, promoting circular principles and inspiring actionable solutions for national sustainability. Tegeta Green Planet reaffirmed its dedication to advancing these environmental objectives and supporting collaborative platforms that drive meaningful change.

Continental is set to construct its first company-owned wind farm adjacent to its tyre production facility in Korbach, within the municipality of Twistetal, Hesse. The initiative will supply electricity directly to the plant, situated roughly eight kilometres away, thereby diversifying the manufacturer's energy portfolio. This strategic move aims to accelerate renewable power adoption, enhance cost competitiveness and diminish reliance on volatile energy markets.

The project features three turbines that, alongside existing solar systems, are projected to satisfy approximately two-thirds of the Korbach plant's electricity requirements. With an annual generating capacity of around 55 gigawatt-hours, the turbines could supply roughly 15,000 average households. Continental has allocated a mid-double-digit million-euro investment, having secured all necessary permits. Groundbreaking is anticipated in 2026, with commissioning expected about 18 months later.

Tyre production consumes significant power for operations like mixing raw rubber and extruding components. The Twistetal wind farm will enable the Korbach plant to meet a larger proportion of demand with locally sourced renewable energy fed directly into manufacturing. This addition complements existing infrastructure while maintaining reliable operations during fluctuating wind or solar conditions. The Korbach facility, employing approximately 2,400 people, produces tyres for passenger cars, motorcycles, bicycles and industrial uses.

The selected Nordex N175/6.X turbines have a hub height of 179 metres and a rotor diameter of 175 metres, reaching a total height of 267 metres, making them among the most powerful onshore turbines available.

The Korbach project represents a key step in Continental's broader strategy to expand proprietary energy generation, with similar initiatives considered globally. The goal is a flexible, economically viable energy supply while increasing renewable power proportion, ideally produced near each manufacturing site.

Continental is evaluating feasibility at worldwide plants, considering local conditions, regulations, storage, integration with existing sources and financial viability. Since 2020, the firm has covered global purchased electricity demand with renewables and reduced tyre production greenhouse gas emissions by approximately 180,000 metric tonnes over four years. By early 2026, coal and heavy fuel oil were eliminated at all production sites, replaced by electricity from renewables, biomass, biogas, LPG and natural gas for steam and heating.

Dr Bernhard Trilken, Head of Manufacturing & Logistics in Continental’s Tires group sector, said, “Having our own wind turbines near the plant will give us more predictable energy costs and reduce our exposure to volatile energy markets – key factors for competitive tyre production in Germany. This is fully aligned with our global strategy to expand our own renewable energy generation and will serve as a blueprint for other sites worldwide.”

Klaus Ohlwein, head of the Continental tyre plant in Korbach, said, “The wind farm will bring major benefits to our location. It will help us cover a significant share of our electricity needs in Korbach with our own renewable sources at competitive and more predictable costs. The electricity generated will be used directly in tyre production, including in mixers and extruders. The project is an important step in our sustainability activities at the site and demonstrates how industrial competitiveness and sustainable energy use can be effectively combined in Germany.”

Pirelli is set to play a central role as the FIM Superbike World Championship concludes the first half of its season this weekend at Donington Park for the UK Round. Marking the final event before the summer break, the Italian tyre manufacturer has equipped competitors with the softest rear compounds from its 2026 standard range. This selection represents a clear advancement in development from the previous year, when riders were limited exclusively to older specification tyres.

For the premier WorldSBK class, the rear tyre allocation is headlined by the SCQ extrasoft compound, intended primarily for qualifying and the Superpole Race. This option, the softest in Pirelli’s portfolio, has already garnered positive feedback from riders during the Emilia-Romagna Round for its exceptional single-lap pace and consistent performance over a sprint distance. Complementing the SCQ are the SCX supersoft and SC0 soft compounds, while front tyre duties are covered by the standard SC1 soft and SC2 medium solutions, with the softer front being the overwhelming preference of last year’s grid, including triple race winner Toprak Razgatlıoğlu.

The notoriously unpredictable British weather remains a critical variable, with cool morning temperatures and frequent rain showers posing significant challenges for teams. Pirelli’s range has historically demonstrated considerable adaptability across fluctuating track and air temperatures, maintaining reliable grip in both cooler and warmer conditions. To address potential precipitation, the allocation is supplemented by DIABLO Wet intermediate and full DIABLO Rain tyres for both front and rear positions, ensuring competitors have viable options regardless of the elements.

In the supporting categories, WorldSSP riders will retain the SCX and SC0 rear compounds alongside the SC1 and SC2 front options. Meanwhile, the WorldWCR field and the emerging talents of the Yamaha R3 World Cup will also be in action, with both series utilising the Pirelli DIABLO Superbike SC1 tyre on both axles throughout the weekend’s racing programme.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “Donington Park is a very distinctive circuit and, in many respects, a unique venue on the FIM Superbike World Championship calendar. The opening part of the lap features a series of fast, flowing corners taken at high speed and rapid changes of direction that require riders to manage significant power while the bike is still heavily leaned over. This demands tyres capable of delivering outstanding grip, precision and stability while maintaining consistent performance over race distance.

"Compared with last year, when only standard range solutions were available and no development specifications were included, this season, while confirming the same compounds introduced in 2025, we will provide riders with the complete 2026 standard range. The SCQ extrasoft compound will be the softest option in the allocation and can be used not only in free practice and qualifying but also, potentially, in the Superpole Race. For the longer races, riders will be able to rely on the SCX supersoft and, should temperatures be lower, the SC0 soft compound – solutions that have already demonstrated throughout the season an excellent balance between outright performance and consistency, as reflected by the many new records that have been set.

"Finally, the weather, which has historically been unpredictable in the UK, will once again be a key factor. Rain and low temperatures, even in the middle of summer, can have a major influence on tyre management and race strategies. Having a complete and versatile range available will therefore be essential to provide the best possible support in any weather conditions.”
