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."

Kuraray America, Inc. marked National STEM Day on 8 November by spotlighting a community educational event that brought together 15 of its volunteers and students from the Houston Japanese Supplementary School at San Jacinto College for a day of hands-on exploration and discovery.

Participants engaged in activities illustrating how science, technology, engineering and mathematics (STEM) converge in chemical manufacturing. Experiments with superabsorbent polymer beads explored chemistry and material properties, while a tour of the college’s facilities introduced industrial equipment. Students also learned about water filtration and distillation processes and how mathematical concepts underpin scientific and engineering applications.

One student showed particular interest in the distillation tower, linking the experience to the Kuraray Group’s contributions to everyday life and its mission of achieving for people and the planet what no one else can. The event also benefited KAI volunteers, who shared technical knowledge, exchanged perspectives and learned alongside potential future scientists and engineers.

Kuraray America thanked Reiko Fuwa and Tomohiro Tani for coordinating the visit, Hans Vandommele for sharing his expertise and all 15 KAI volunteers. The company also expressed appreciation to San Jacinto College for facility access and to the Houston Japanese Supplementary School students for their curiosity, enthusiasm and thoughtful questions.

Liberty Tire Recycling attended the 2026 SEMA Show in Las Vegas, held from 3–6 November at the Las Vegas Convention Center. The automotive aftermarket event, one of the industry's largest, drew over 160,000 attendees from the automotive, tyre and transportation sectors to review new products, technologies and business opportunities.

The Lakin Tire brand, a consistent SEMA exhibitor, once again used the show to reinforce industry relationships and present Liberty's tyre collection, recycling and sustainable resource management capabilities. Personnel from Grade/Used Tires, Commercial Truck Tires, Metals, Recycling and Collection, together with corporate and regional leadership, met customers, suppliers and industry professionals from around the world.

The booth received existing and prospective customers from numerous tyre and automotive segments during the week. Costco Wholesale Corporate Office, United Tires and UTU Wholesale were among the organisations that stopped by to examine Liberty Tire's products, services and nationwide reach. The company viewed the event as an effective forum for monitoring emerging market trends and demonstrating its position in recycling and sustainability, alongside its focus on innovation, workforce development and circular economy principles.

A memorable moment came when a high school shop teacher and students, attending through a special educator programme, toured the booth to learn about tyre recycling and industry operations. Liberty team members provided industry insights, outlined career pathways and acknowledged educators' contribution to developing future skilled trades professionals, supplying tyre inflation gauges for classroom use.

Laufenn, Hankook's associate brand, earned a ‘Good’ ratingwith an overall score of 2.2 for its G Fit 4S in the Auto Bild Allrad all-season SUV tyre test published on 8 October 2026 (issue 41). The tyre competed credibly against 11 rivals from established premium marques, finishing competitively in a 12-strong field.

Wet handling proved a particular strength, with the G Fit 4S collecting the second-highest rating shared with other models. Aquaplaning resistance also impressed, as the tyre held its line until stability began to fade at roughly 100 kmph (62 mph). In snow, it recorded the third-shortest braking distance, matching two other contenders.

Testing spanned snow, wet and dry disciplines, each weighted equally in the final ranking, with a third-generation MINI Countryman serving as the test vehicle. Snow assessments were carried out in New Zealand, while European venues hosted the wet and dry evaluations. The jury's conclusion underscored Laufenn's value-focused positioning, finding the G Fit 4S a solid option for cost-conscious buyers.

Tyres Europe has underscored that tyres qualify as fully recyclable under ISO 22628:2002 and UN Regulation No. 133, describing the established methodology as a robust foundation for assessing tyre recyclability. The organisation recently set out its position on the matter.

The distinction between recyclability and actual recycling rates is central to the group's argument. Recyclability refers to the technical potential of a product and its materials to be recycled, while the real rate hinges on treatment capacity and demand for secondary raw materials. Regulatory frameworks should therefore separate the two concepts clearly and align with an internationally recognised standard.

Tyres consist of rubber compounds, chemical additives and reinforcing textile and steel cords, and at end of life they are separated into rubber, textile and steel fractions, all of which existing mechanical or chemical routes can recycle. Mechanical processing yields rubber granules and powders usable as secondary raw materials across many applications, recovered textiles can be further processed and valorised, and cleaned recovered steel can re-enter metal recycling and steelmaking.

Tyres Europe pledged continued cooperation with policymakers and value-chain partners to strengthen circularity and maximise recovery of valuable tyre materials in Europe, with the full paper available on its website.
