Circtec’s technology converts discarded tyres into a slate of products

King Willem-Alexander inaugurated what Circtec calls Europe’s largest and most advanced chemical recycling facility for end-of-life tyres, marking the start of operations at the company’s Delfzijl plant in the Netherlands’ northern chemical cluster.

The facility, whose investment was announced in May 2024, has completed construction and commissioning of its first phase and is now processing 50,000 tonnes of waste tyres a year. During the ceremony, the King symbolically began operations by feeding tyre material into Circtec’s proprietary CIFR pyrolysis reactor. The event was attended by the Netherlands’ Deputy Prime Minister and Minister of Climate and Green Growth, along with the British Ambassador to the Netherlands.

Circtec’s technology converts discarded tyres into a slate of products including a marine fuel marketed as HUPA, circular naphtha for use in plastics and chemicals and recovered carbon black for reuse in tyres, rubber and plastics. The plant can also supply tyre pyrolysis oil to petrochemical and refining customers as a lower-carbon feedstock.

The Delfzijl project follows more than 15 years of technology and product development by the company. At current capacity, the plant is expected to process roughly 6 percent of Europe’s annual waste tyre stream. More than half of Europe’s end-of-life tyres are still burned in cement kilns or exported to Asia for disposal, according to Circtec.

An ISO-standard life cycle assessment commissioned by the company indicates the plant could cut greenhouse gas emissions equivalent to about 3 percent of the Dutch chemical industry’s national emissions once the site reaches full scale.

Circtec plans to begin construction of a second phase later this year, expanding capacity in modules to a total of 200,000 tonnes of tyres a year.

The company has secured long-term offtake agreements for its entire output. Birla Carbon will take the recovered carbon black for its Continua de-carbonisation product line, while British Petroleum has contracted volumes of the marine fuel, circular naphtha and tyre pyrolysis oil.

The project is backed by Novo Holdings and A.P. Moller Holding, which closed a Euro 150 million funding round for Circtec in 2024. The company is planning additional plants globally, both as owner-operator projects and through joint-venture licensing.

During the visit, the King toured the facility and met employees as well as representatives from British Petroleum, Birla Carbon and Dutch tyre recycling body RecyBEM. Discussions also involved local and regional authorities on the plant’s economic and environmental role in the Groningen region.

Commenting on the occassion, Circtec Chief Executive Officer Allen Timpany said, “Circtec now moves forward to operate the first phase of this plant and to expand it to its full designed and permitted size. Let us work together to scale this success further. So that this plant may inspire others, here in the Netherlands and far beyond, to rethink waste, reimagine value, and to keep moving forward, tenaciously, innovatively, and with strategic vision toward a sustainable and resilient industrial future”.

Speaking during the inaugural ceremony, Netherlands Deputy Minister and Minister of Climate and Green Growth Sophie Hermans said, "What we see here at Circtec is Green Growth at its best. Every year, 180,000 tonnes of used car tyres will be given a second life as a high-quality raw material. That is circular economy on an industrial scale. This factory shows that we can and want to become more sustainable in the Netherlands and dare to build new, future-proof industry. Good for our climate, good for our economy and good for the earning capacity of the Netherlands."

Hankook Tire, the exclusive tyre supplier for the ABB FIA Formula E World Championship, played a central role in the season’s pivotal Japanese double-header. As the official race tyre for all competitors, the company’s iON Race compound was put to the test under extreme and shifting conditions during Rounds 14 and 15 of Season 12 at the 2026 TDK Tokyo E-Prix.

The weekend’s on-track action produced two dramatic winners. CUPRA KIRO’s Dan Ticktum snatched victory in Round 14 with a last-corner overtake on Jake Dennis, while Nick Cassidy completed the podium. The following day, Mahindra Racing’s Nyck de Vries claimed Round 15, finishing ahead of Cassidy and Dennis, who secured second and third respectively. The entire paddock also observed a period of remembrance for the late Cyril Blais.

The 2.575-kilometre temporary circuit, featuring 18 corners and situated around Tokyo Big Sight, hosted its first-ever night races, drastically altering track conditions from practice to competition. Unstable weather compounded the challenge, with a Sunday thunderstorm cancelling Free Practice 3 and leaving a damp, drying surface for Round 15 that demanded constant adaptation in tyre warm-up and strategy.

Throughout the weekend, Hankook’s iON Race tyre demonstrated reliability across the evolving grip levels and temperature swings. Following the Tokyo results, Dennis retains the championship lead with 146 points, narrowly ahead of Mitch Evans and Pascal Wehrlein. The title battle remains fiercely contested and will be resolved at the season-ending Hankook London E-Prix double-header on 15–16 August.

Manfred Sandbichler, Senior Director, Hankook Motorsport, said, “Bringing Formula E night racing to Tokyo for the first time made this a distinctive weekend and one of the more unusual tyre assignments of our season. The contrast between afternoon running and the 20:05 races shaped how teams prepared for both events, and the iON Race managed that transition and the changing weather conditions well, delivering consistent and predictable performance as the circuit cooled through the evening.”

Tegeta Green Planet recently contributed to the ‘Circular Future’ green camp, an environmental education initiative organised by CENN and funded by the European Union. The camp, which hosted 23 teenagers from the Adjara and Kakheti regions, was designed to deepen ecological understanding, advocate for waste-free systems, and inspire long-term behavioural change among the next generation.

Throughout the week-long gathering, young attendees engaged with forward-thinking methods for minimising refuse, prolonging product life cycles and improving separation and recovery processes. Interactive workshops translated abstract circular economy theories into tangible daily actions, equipping participants with the know-how to conserve materials and shrink their personal environmental toll.

A noteworthy component of the programme occurred on 22 July, when a specialised seminar titled ‘Circular Economy: Waste Reduction and Recycling for Public Health’ was convened. Co-hosted by Tegeta Green Planet, the UNDP and the Waste Management Business Association, the seminar examined the intersection of ecological integrity and human well-being, illustrating how robust recycling systems directly benefit community health outcomes.

Closing the day’s agenda, Tegeta Green Planet’s Director, Shalva Akhvlediani, offered an in-depth look at the Extended Producer Responsibility model currently unfolding in Georgia. He traced the journey of end-of-life vehicle components – from used tyres and spent lubricants to depleted batteries – through collection, transport and reprocessing channels. Akhvlediani also highlighted his organisation’s network of over 350 domestic producers and importers, stressing that youth education remains a cornerstone of their mission. The floor was then opened for a lively exchange, where students posed probing questions, debated local environmental dilemmas and floated their own grassroots suggestions, reinforcing the message that responsible resource use begins with informed individual choices.

Nexen Tire reported second-quarter revenue of KRW 891.3 billion and operating profit of KRW 34.3 billion, as growth in Europe and higher sales of premium products supported performance despite rising costs and geopolitical uncertainty.

Revenue increased 10.8 per cent from a year earlier, driven by demand in key markets, particularly Europe, the company said .

The tyre manufacturer said its strategy of expanding original equipment (OE) supply programmes and diversifying replacement (RE) tyre sales helped support growth amid weaker demand in the automotive market. Sales of 18-inch and larger tyres accounted for 38.8 percent of total sales, up 3.6 percentage points from a year earlier, reflecting a greater focus on premium products.

Profitability came under pressure as higher raw material prices and increased ocean freight rates raised costs. The company also incurred one-off expenses following the final ruling on US anti-dumping duties, which resulted in a higher tariff rate than previously expected.

Europe was the strongest-performing region during the quarter, with revenue reaching KRW 407.2 billion, the first time quarterly sales in the region have exceeded KRW 400 billion.

The company attributed the growth to higher OE sales from its European manufacturing plant, business expansion in the UK, Türkiye and other markets, and improved distribution and logistics following the addition of a finished-goods warehouse at the plant.

In South Korea, demand for electric vehicle (EV) and sport utility vehicle (SUV) tyres remained strong. Nexen Tire said its expanding OE portfolio, which includes the Hyundai IONIQ 6, Kia's EV3 to EV9 models and other domestic electric vehicles, supported higher OE revenue and increased sales of larger-diameter tyres.

The company also said continued growth in rental sales within the replacement market improved its product mix, while its first OE supply agreement with BYD strengthened its position in the global EV market.

Alongside its financial results, Nexen Tire said it had expanded its OE supply during the quarter to electrified models including BYD vehicles and the Hyundai STARIA EV. Supply to premium automotive brands also increased from a year earlier, supported by research and development initiatives, including AI-based performance prediction technologies.

"Despite growing cost pressures from external factors, we have continued to achieve top-line growth on the back of strong sales in key markets," said John Bosco (Hyeon Suk) Kim, CEO of NEXEN TIRE. "With the stable ramp-up of the second-phase expansion at our European plant and the results of our distribution improvements in North America, we expect more tangible improvements in earnings."

Pirelli has officially communicated to all Formula 1 teams the tyre compound selections for the upcoming Dutch, Spanish and Italian Grands Prix. The Italian manufacturer has opted for the medium-range C2, C3 and C4 compounds for the events at Zandvoort and the new Madrid circuit, while the Monza race will see the softest available tyres, the C3, C4 and C5, deployed.

For the Dutch Grand Prix at Zandvoort, Pirelli has confirmed the same compound choice as the previous year. The coastal circuit is defined by its medium and low-speed corners, including two banked turns, which place significant vertical and lateral loads on the tyres and demand high aerodynamic downforce. The track surface itself offers low inherent grip, a challenge compounded by sand from the nearby beaches being blown onto the asphalt, further affecting tyre performance.

The Italian Grand Prix at Monza presents a contrasting challenge, with its recently resurfaced track encouraging teams to run low-downforce configurations. The pit lane loss time for a tyre change is among the highest of the season, incentivising teams to extend stints and manage degradation to achieve a one-stop race. However, the potential for high ambient temperatures could complicate this strategy, making tyre management more difficult.

Making its debut on the calendar as the Spanish Grand Prix, the semi-permanent street circuit in Madrid features 22 highly varied corners, significant elevation changes and the longest banked turn in the championship. Simulations indicate that the loads on the tyres are comparable to those at Silverstone and Spa-Francorchamps. Consequently, Pirelli’s selection of the medium-range compounds is designed to favour a two-stop strategy and offer greater protection against overheating, a risk to which the softer C5 compound would be particularly vulnerable in warm conditions.
