How will the collaboration with Michelin influence the future of the company? What vision do the companies share?

Michelin evaluated our recovered carbon black material in 2016. Since then, they have made significant testing of quite large volumes of our material over time to evaluate its consistency and quality. This is probably the most important parameter for any tyre manufacturer to use recovered carbon black. The interest in the technology itself started to grow as they saw that the performance of the recovered carbon black material was quite impressive. Over time, they started doing due diligence on the technology during those years. We intensified the negotiations in the early stages of 2020 and finally entered into a partnership agreement in April where Michelin invested 20 percent in Enviro. But, that was only one part of the partnership we envisioned. We also had, from the beginning, discussions about how we can provide the technology as a part of their solution to build a business model around mining tyres. This way, they could also offer their mining customers a solution for the recovery of the mining tyres. In that aspect, we negotiated regarding a joint plant project we are currently building in the Antofagasta region of Chile. We are also preparing the permitting for a plant in Uddevalla, Sweden, of 60,000-tonne ELT capacity for car and truck tyres.

In addition to that, we evaluate different technology experiences from both sides where we contribute with our experience in pyrolysis and treating end-of-life tyres in a professional way. Michelin is contributing with their extensive knowledge about developing and innovation into industrial capacity plants. What we have is a very intense collaboration on a more or less daily basis.

Going forward, we see that Michelin has a strategic ambition to replace up to 100 percent of the materials in the tyres with sustainable alternatives. Carbon black is one of the materials where we think that quite large volumes can be replaced over time. They're also involved in replacement and development of different types of oils in the tyres. From Michelin’s side, I think they have a wider interest in the recovery of all the materials in the tyres. This also aligns with our interest since we are recovering tyre pyrolysis oil and doing that quite successfully. We expect more plans in collaboration with Michelin in one way or another. Their investment in our company and the clear engagement in showing the market that they're using our material in motorcycle racing tyres in Moto E and in performance tyres for racing cars is helping us to get the acknowledgement in the market. This is important for our growth and our expansion plan.

How are you matching the quality and consistency of the recovered carbon black to virgin carbon black? Can you also please elaborate on the collaboration with AnvaPolytech, where Enviro completely replaced virgin carbon black used in Volvo's rubber components back in 2015?

We are using our patented batch process, which is a fixed batch process. The technology that we are using was developed for over 20 years to maintain control of the pyrolysis process. We can make sure that the result of the pyrolysis in the material is consistent, which means that we are not creating new carbon, as you easily do when you have a continuous process, and we are making sure that the pyrolysis process has evaporated all the volatiles out of the carbon fraction. This is very important and we control this with the system in multiple parameters that we measure during the process. We also have a significant quality control system downstream. So, in the post process of the pyrolysis, we do multiple quality checks. Before each shipment, we have ASTM standard controls for about 10 different parameters where we compare to the industry ASTM standard normally used for carbon black. There are a few ASTM measurements used for virgin carbon black that are not applicable for all recovered carbon black products, but the majority of the tests can be similar and we keep a very high consistency there. This is also one of the main achievements of the company since January 2016. We made the first commercial delivery to AnvaPolytech and they are a rubber component supplier to Volvo Cars. They have been involved with us before the commercial deliveries in the research and development of the material for rubber components. They were also involved in lots of different types of testing, where meeting the automotive standard for EPDM rubber components was a very significant part, and also got the final approval from Volvo Cars to replace the material. Since 2016, we have replaced 100 percent carbon black in those components with our material. I think it's now more than 100 million components delivered from Anva to Volvo Cars.

The gas produced during the pyrolysis process is used to fuel the machinery itself. Is there a commercial value for the gas in this market and are you exploring those business verticals?

It is a very valid question; we are producing new pyrolysis gas, and in the process, we condense out the oil, but there will be a fraction of gas that is not condensable. That gas is the excess gas that we use for the next pyrolysis phase. In our current plant at Åsensbruk, we use the excess gas and part of the oil to power the main process and the post process for heating purposes. In the new plants we will be building, for instance, one in Sweden, we plan to start production in the fourth quarter of 2023, where we will use green energy from wind, solar, water and waste to provide energy. In this case, the excess gas will be used only to heat the dryer system in the post process. Does it have a commercial value? I think some markets do; it might be used also in-turn to produce energy or electricity, but at the moment, this is not something that we are exploring further in detail.

The company recently received two ISCC certifications, one for the pyrolysis oil and the other for the carbon black. What were the challenges in earning the certifications and are there any other benchmarks that you're targeting for any other product in the future?

We are very proud to be the first to achieve the certification for the recovered carbon black. It is an important step for both the certification and for us as a company. We are already seeing some of the players in the tyre industry looking to certify according to ISCC now. This means that there will be a higher value in connection to using that type of material. There are always challenges with being certified and the most challenging maybe is to follow the certification requirements in terms of how, when and where to measure. We need to make sure that this is something that we can live up to when we are audited annually. We must also commit resources and capabilities to do this. We also needed to involve our supplier of tyre material, which, in Sweden, are Ragn-Sells. They are also audited by the certifier.

Enviro was evaluating business prospects in India. What is the current status of opening a full-size plant? Pyrolysis is banned in India across almost all states by the pollution board, and we're seeing various companies being ordered to shut down plants. Where does Enviro fit in and what are the developments?

Yes, we have been conducting meetings together with the Swedish Energy Agency, Swedish Export Organization, Business Sweden and a few other organisations including India-Sweden Innovations Accelerator and Confederation of Indian Industry in India. We have been exploring the Indian market for many multiple axles, and during the last two years, we are meeting with all the major tyre producers, both local and international. We are meeting with oil companies downstream who are potential customers for oil. We are meeting with waste treatment and tyre treatment companies locally and also making presentations to most local governments. However, we feel it is a bit too early for us to enter India on a more massive basis.

We have decided strategically that we will start with Europe followed by probably the US in the next phase. I think that will help India to monitor what is happening with the technology and how it can be a part of the system in those markets. We can then use that as a showcase for creating a sustainable and long-term system for the Indian market. We hope that this display of the system will be appreciated by the players in India to implement and also be some kind of inspiration to make that happen. In regards to pyrolysis being banned, I think it's probably a very correct decision because the pyrolysis technologies that we have seen being used in India are mainly Chinese versions where the environmental 360-degree impact has not really been considered. I think it was a very necessary decision.

The system for import and collecting for the pyrolysis industry was not really in place at that moment. But I think we can showcase together with a few of our peers in the European market that batch pyrolysis process and pyrolysis in general can be made with a very sustainable and safe technology with the highest possible emission control systems. We are hoping that by setting an example in Europe and showing both the technology and the system, maybe we will enter India in the next five years.

What are some of the constraints that you see in entering the Indian market?

I think one constraint that we are struggling with – mainly in Europe, but also in other markets – is that end-of-life tyres are viewed purely as waste materials. To really get our authorities and government regulators to understand that we are making a transition of waste materials into something that can sustainably replace fossil resources is a challenge. We are in the right direction. ISCC certification is one step.

Reach of the materials is another step. I think that transition to get aligned with the current legislation in many countries is still a hurdle. Even if it's improving, making this kind of large transition of an industry that is not really present at the moment requires financial support. Financial investors need to be willing to take a little bit of a risk to make the industry change as rapidly as it needs to. It's not enough for the tyre industry if there is one company able to provide the small volume to the market; they need multiple suppliers and large volumes to replace larger volumes of virgin material. The volume is a constraint itself. We hope, together with Michelin and other parties that we're working with, to provide larger volumes in the coming 10 years. Our ambition is to establish at least 30 plants globally in the coming decade. We also hope that our competitors are also successful in India.

What potential do you see in the Indian market, being one of the biggest automotive markets in the world, in terms of government support or the infrastructure for the products Enviro produces?

One of the opportunities is the growing automotive market. There is also a foundation of industry there in India for a long time. There is a tradition to produce tyres with a lot of knowledge, research and development around tyres and rubber materials, which I think is a very interesting potential itself. The competence around the materials in India is significant. I think the size of the market itself is an opportunity. If you choose to see the immaturity of the collection system as an opportunity, which I do, I think there is a lot of potential to establish from ground-up, a workable system with different stakeholders where I think local and national government needs to play a role, but it needs to be still on market conditions. I think the model that we will be showcasing in Europe will be attractive for both the government and local private stakeholders like the tyre industry and rubber industry.

In a broader sense, what is the future for the company and what are your goals? What are you excited about?

There are very clear targets from the tyre industry since they are consuming more than 70 to 80 percent of the carbon black material in the world. We have very clear targets for replacing fossil-originated materials with recovered or sustainable materials. We are very excited about the volume potential we see there. We have started to take steps in that direction with multiple tyre producers. The regulation in Europe and other countries to reduce the fossil content in oil products and chemical products is very positive for us. ISCC is a very important tool for the market to implement recovered and bio-based materials which have tax incentives. These enable us to launch our expansion plan, which, as I mentioned, is for the next 10 years to open 30 plants globally. We are excited that we are now in the position to work in establishing one plant with Michelin in Chile and in parallel a plant in Sweden with more or less the same time scheduled to start production. In the pipeline, we have several very interesting projects building up.

Are there other manufacturers or automotive players that are satisfied with the level of quality in your recovered carbon black? Are there any projects in the pipeline?

We have seen the interest significantly increasing in suppliers to the automotive industries and to other core manufacturers since we got the ISCC certificate for our products. But I think that we could better market what we have achieved together with Volvo in order to really get the other car brands into using more of our material. I think we have some homework to do there, because what we do is too little known to them at the moment. So there is work to be done there. We know we can achieve it. We should focus on letting them know what we can do. We are working with some other automotive manufacturers not only for the recovered carbon black but also to help them achieve their zero-emission objectives. So that could be related to oil, carbon black, steel and potentially other materials such as carbon fibre, for instance. (MT)

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.”
