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.

Nouryon, a leading supplier of organic peroxides and a developer of organic peroxide solutions, has formally announced the completion of capacity expansion of its organic peroxides manufacturing facility in Ningbo, China.

The company's production capacity for Perkadox 14 and Trigonox 101 organic peroxide products, which are crucial components for altering polymer characteristics and crosslinking rubbers and thermoplastics, has increased to 6,000 tonnes each as a result of this capacity expansion. Furthermore, by improving the qualities of recycled polypropylene (R-PP), these solutions can also allow consumers to employ recycled polymers in applications that were previously exclusive to virgin plastics.

Alain Rynwalt, Senior Vice President – Performance Materials, Nouryon, said, “Nouryon is a world leader in essential ingredients for the polymer industry and this expansion highlights our dedication to supporting our customers’ growth across the entire polymer cycle. Customer interest in improving the properties of recycled polypropylene continues to rise, in line with increased consumer awareness and more stringent regulations.”

Sobers Sethi, Senior Vice President – Emerging Markets and China, Nouryon, said, “Asia Pacific is a key region for Nouryon and our most recent expansion in China strengthens our supply position even more in this growing region. Our customers rely on our existing network of manufacturing facilities and innovative technologies, and we are pleased to build more capacity to meet growing customer demand around the world.”

Trinseo, a speciality materials solutions provider, has signed agreements to supply its polycarbonate technology license as well as all proprietary polycarbonate production equipment in Stade, Germany to Deepak Chem Tech Ltd, a wholly owned subsidiary of Deepak Nitrite Limited, a diversified chemical intermediates company based in Vadodara, Gujarat, India.

The combined deals are worth USD 52.5 million. Subject to significant milestones, the business anticipates receiving around USD 9 million by the end of 2024 and an additional USD 21 million in the first part of 2025. The firm has made the decision to leave Stade, Germany, with this disposal of the production assets.

Frank Bozich, President and Chief Executive Officer, Trinseo, said, “While Trinseo recently announced its decision to exit virgin polycarbonate production, our polycarbonate technology is highly valued and the manufacturing equipment in Stade, Germany, can be utilised in India by Deepak. These are the initial steps of a strategic, collaborative partnership with Deepak, as we explore additional opportunities to leverage our technology portfolio and expand in higher-growth areas such as India.”

China's butadiene exports have experienced significant growth in recent years, particularly in 2021 and 2024. According to Sublime China Information (SCI), this surge is primarily driven by supply constraints in key regions, including the US and Southeast Asia.

Export Volume and Price Trends

In 2021, China's butadiene exports reached a historic high due to a supply gap in the US market. According to SCI, this trend continued in 2024 as reduced deep-sea cargo shipments and production challenges in Southeast Asia further tightened global supplies. From January to September 2024, China's total butadiene exports surged by 111 percent year-over-year to approximately 120.8 kilo tonnes.

The average export price of butadiene has fluctuated over the past five years. In 2023, weak demand in South Korea and competition from deep-sea cargoes led to a significant decline in export prices. However, in 2024, supply shortages from key regions drove prices to a five-year high. As of September 2024, the average export price reached USD 1,391 per metric ton, a 35 percent month-over-month increase, added SCI.

Export Destinations and Regional Dynamics

The majority of China's butadiene exports are directed to South Korea and Taiwan. In 2024, South Korea accounted for 74 percent of total exports, a significant increase from the previous year. This surge was driven by factors such as limited domestic supply and increased demand for spot butadiene.

While China's butadiene exports have been strong, the long-term potential for significant growth in deep-sea exports remains limited due to established supply chains and regional demand dynamics. Most of China's exports are currently concentrated in Northeast Asia, with limited opportunities for expansion into other regions.

Future Outlook

SCI added that 2025 China's butadiene supply is expected to be relatively sufficient, and export volumes may increase further. However, the sustained growth of exports will depend on various factors, including downstream demand in key markets, the availability of deep-sea cargoes, and the development of new production capacities in other regions.

Despite these uncertainties, China's butadiene industry is well-positioned to capitalize on global supply-demand imbalances and continue to play a significant role in the global market.
