Wastefront AS has partnered with Newcastle University to study the characterisation and enhancement of Wastefront’s recovered carbon black (rCB).

As one of the UK’s top universities and a world leader in sustainability, Newcastle University’s partnership with Wastefront will see cutting-edge industry innovation emerge from research conceived in the North of England – ensuring the region is at the forefront of progressing circularity across Europe.

The work is timely as Wastefront gears up to play a crucial role in eliminating the UK’s waste tyres export by creating a local, circular solution to a global problem. To prevent waste tyres from burning in cement kilns, Wastefront will use commercial operating technologies to convert end-of-life-tyres (ELTs) into useful commodities, including rCB.

The study will focus on rCB interaction with rubbers and its correlation with prospective industrial applications, directly supporting Wastefront’s efforts to enable the rCB it produces to be used in new products. The scope of work undertaken by Newcastle University over the next 18 months will:

1. Quantify the interaction of the rCB with a set of different solvents with varying degrees of dispersion interaction.

2. Develop methods to better understand the nature of the surface within the rCB material.

3. Investigate applications for the rCB in other materials.

Of significance, within this scope of work, the study will develop methods to reduce inorganic components in rCB, improving its chemical and material properties to ensure Wastefront produces a superior product compared with its rCB competitors. This will include identifying rCB reinforcement in rubber goods.

The team from Newcastle University undertaking the rCB study will be:

• Professor Katarina Novakovic – Principal Investigator, Reader in Polymer Engineering

• Professor Steve Bull – Co-Investigator, Cookson Group Chair of Engineering Materials

• Dr Deepashree Thumbarathy – Post-Doctoral Research Associate, Chemical Engineer

• Dr Tim Blackburn, Business Development Manager

Wastefront CTO, Henrik Selstam, comments:

“Circularity is central to the work Wastefront is undertaking to tackle the scourge of ELTs – and expanding our understanding of recovered carbon black is key to realising this goal. As we continue to grow, so too will the uses and capabilities of the products we produce – none more so than recovered carbon black.

“We are delighted to partner with Newcastle University to further advance the commercial capabilities of recovered carbon black through our joint studies. “Ensuring we can continue to implement our at-scale solution in the UK, Europe and Globally will require the input of leading experts in their fields, so we look forward to working closely with Professor Novakovic, Professor Bull, Dr Thumbarathy and Dr Blackburn in the months ahead.”

Newcastle University Pro-Vice-Chancellor for Research Strategy and Resources, Professor Brian Walker, adds:

“At Newcastle University we are delighted to add this exciting partnership with Wastefront to our portfolio of research that advances sustainable innovation and the circular economy and enables progress towards a net-zero economy. We are especially pleased that Wastefront will promote inclusive economic growth here in the North East, with its roots in the local area and the construction of its new plant at the Port of Sunderland.“

 Wastefront uses pyrolytic reactors that utilise thermal depolymerisation known as ‘pyrolysis’ to break down a tyre’s materials at elevated temperatures. By sending tyres through these reactors, recovered carbon black (a substitute for virgin carbon black) is produced, in addition to combustible gas, liquid hydrocarbon, and heat. The carbon black is then washed and milled to upgrade the chemical properties and can be used as a complement to natural rubber in tyre production, mechanical rubber goods or as a filler for plastics.

Once fully operational in 2025, Wastefront’s £100 million tyre recycling plant in Sunderland will produce rCB from a supply of 20 percent of the UK’s yearly total of ELTs. By integrating Wastefront’s rCB into new tyres, the emissions for each tyre subsequently produced will be reduced by 80 percent.

Continental is accelerating its transition towards a circular economy by systematically increasing the use of renewable and recycled materials in its tyres. The company, which averaged a 26 percent sustainable material share in 2024, has set an ambitious target to raise this to at least 40 percent within five years. This strategy involves not only internal innovation but also actively encouraging its supply chain to develop and provide more sustainable raw materials.

A critical area of development is finding green alternatives for reinforcement materials like steel and textiles, which are essential for tyre safety, durability and performance. These materials can constitute over 18 percent of a passenger car tyre, and even more in commercial vehicle tyres. Continental is already integrating recycled steel and is pioneering the use of polyester yarn made from recycled PET bottles. Depending on the tyre size, the carcass of a single passenger car tyre can incorporate the equivalent of up to 15 bottles. This recycled polyester, developed with partner OTIZ, is verified to cut CO₂ emissions by approximately 28 percent compared to conventional materials and is already featured in production tyres like the UltraContact NXT.

The company's sustainable material portfolio extends beyond reinforcements. It includes synthetic rubber derived from used cooking oil, bio-based resins from waste streams and silica obtained from rice husk ash. Complementing these material advances is a commitment to greener manufacturing processes. Together with Kordsa, Continental has developed COKOON, an adhesion technology that bonds textiles to rubber without harmful chemicals. In a move to uplift the entire industry, this innovative solution has been made available to all tyre manufacturers as a free, open-source license, demonstrating Continental's broader commitment to fostering industry-wide sustainability.

Dr Matthias Haufe, Head of Material Development and Industrialization, Continental Tires, said, “We are not reinventing the wheel – but we are reinventing the tyre, with more sustainable materials and more environmentally compatible production processes. It’s not just about the rubber itself. We also focus on the materials that give the rubber its shape and make tyres stable and safe. Recycled steel and polyester yarn made from recycled PET bottles are important for more sustainable tyre production. Our goal is to use at least 40 percent renewable and recycled materials in our tyres within five years. Every alternative material brings us an important step closer to this goal. When it comes to sustainability, it’s not just the materials we switch to, but also those we deliberately do without.”

Pyrum Innovations AG has officially announced that it will break ground on its next wholly-owned recycling facility in Perl-Besch on 14 November 2025. This new facility is a landmark project for the company, designed to be its largest to date and more than double its existing recycling capacity by processing in excess of 22,000 tonnes of used tyres each year.

The financial framework for this expansion is already taking shape. The project is supported by a diversified funding strategy that includes drawing on a EUR 25 million credit line from BASF and a committed debt financing term sheet from a major European bank. Finalising the package is contingent upon an agreement with Saarland authorities regarding land costs. Crucially, securing the Perl-Besch financing will unlock access to further substantial funding, including a second loan tranche from BASF, paving the way for additional projects in the company's rollout plan.

From a technical and logistical perspective, the Perl-Besch plant will be a state-of-the-art operation. It will be constructed on a 25,000-square-metre site in the strategically important border triangle of Germany, France and Luxembourg. The integrated facility will comprise a shredder plant, three next-generation Pyrum reactors, its own power plant and a grinding and pelletising plant. Insights gained from the existing plant in Dillingen are being directly applied to optimise construction and commissioning, aiming for a faster ramp-up to full production. The site was selected for its superior logistical advantages, offering direct connections to the Moselle River, railway lines and a nearby motorway to efficiently manage material flows from across Europe.

This new facility is central to Pyrum's financial roadmap, with the company projecting it will reach break-even upon its commissioning in 2027. Achieving this milestone is anticipated to create significant momentum and provide a solid foundation for the accelerated rollout of the company's broader project pipeline.

Pascal Klein, CEO, Pyrum Innovations AG, said, “Now that all the legal formalities have finally been clarified – development plan, planning permission and access to the site – we can hardly wait for things to visibly get underway. In the background, planning is already well advanced: The site has been prepared, numerous plant components with long delivery times – so-called long leads – have been ordered and the architect’s tenders for the ground work are underway. During construction, we will also benefit from the experience we have gained from the expansion of our main plant in Dillingen, so we are planning to start production in Perl-Besch in 2027.”
