Continental, which has been expanding its activities in the area of circular economy, has signed a development agreement with Pyrum Innovations, a specialist in the pyrolysis of end-of-life tyres. The aim of the collaboration is to further optimise and expand the recycling of end-of-life tyres through pyrolysis.  

In the future, among other things, particularly high-quality recovered carbon black (rCB) is to be obtained for tyre production of Continental, the company said in a release. Carbon black is an important component of many tyre compounds. By using high-quality carbon black, the performance of tyres can be specifically improved. Continental’s subsidiary, Reifen-Entsorgungsgesellschaft (REG), will begin supplying end-of-life tyres from the premium manufacturer to Pyrum as early as March 2022. 

In the long term, the aim is to establish a circular economy concept for the recycling of end-of-life tyres. Since Pyrum's IPO in 2021, Continental has already held a strategic minority stake in the company. 

Dr. Andreas Topp, Head of Materials, Process Development and Industrialisation at Continental Tires, said, "In Pyrum we have found a partner who has developed a particularly efficient pyrolysis process. Together we want to further develop the processes for the pyrolysis of end-of-life tyres. Our goal is to recover valuable materials and high-performance raw materials on an industrial scale in the future, among other things for Continental's tire production. Continental has ambitious sustainability goals.
It is important for us to conserve resources. That's why we are continuously expanding our solutions for the circular economy." 

Pascal Klein, CEO of Pyrum Innovations, said, “We have been in close exchange with Continental for some time and are looking forward to further expanding our collaboration with this agreement. Our business model is already fully sustainable. Together with Continental, we now want to go the next step towards a sustainable tire industry." 

Industrial carbon black is an important resource used in tyre production and in the manufacturing of other industrial rubber products. Carbon black recovered from end-of-life tyres saves fossil raw materials and will contribute significantly to reducing CO2 emissions. The specific use of carbon black in rubber compounds increases the stability, strength and durability of tyres.
In a standard passenger car tyre, the amount of carbon black to which tyres owe their black colour is 15-20 percent. 

Claus Petschick, Head of Sustainability Continental Tires, said, “Sustainable materials and circular economy are an important part of Continental's sustainability strategy. End-of-life tyres are a raw material for Continental in the wrong place. We believe that circular economy is the model of the future. Modern, highly efficient pyrolysis processes are very important to us in this regard. As part of our ambitious sustainability strategy, we will increase the use of sustainable materials in our tyre products to 100 percent by 2050 at the latest, for which recycled materials will make a significant contribution. As part of a closed-loop system, tyres will in future become the starting material for new tyres." (TT)

Denka Company Limited announced it would record an extraordinary loss of approximately 16.1 billion yen (£85.8 million) as an impairment on manufacturing facilities at its US subsidiary. It will indefinitely suspend chloroprene rubber production at the Louisiana plant.

The Japanese chemical manufacturer, which holds a 70 percent stake in Denka Performance Elastomer LLC (DPE), cited mounting operational challenges, including unexpectedly high costs for pollution control equipment and declining production volumes at the American facility.

“DPE has faced significant cost, production and other challenges at its facility in the United States,” the company said in a statement. “Rising costs are attributable to, among other factors, identification, design, purchase, installation, and operation of pollution control equipment to reduce chloroprene emissions that DPE did not anticipate being required when it acquired the facility from E.I. DuPont de Nemours and Company.”

The subsidiary was established in December 2014 and acquired the chloroprene rubber business from DuPont in November 2015. The Louisiana facility was intended to serve as a second manufacturing site in North America, complementing Denka’s Omi Plant in Itoigawa, Niigata, Japan.

However, according to the company statement, DPE has struggled with multiple operational issues, including “rising energy costs and a shortage of qualified staff necessary to operate new pollution control equipment and implement other emission reduction measures. “

Production volumes have declined partly due to “operational restrictions arising from the pollution reduction measures and unscheduled plant outages associated with supply chain disruptions and severe weather events,” Denka said.

The company noted that these challenges, combined with changes in the global economic environment for chloroprene rubber, have pressured profitability, making near-term improvement difficult.

Denka confirmed that DPE employs 250 people as of December 2024 and will not restart its chloroprene rubber manufacturing facilities following a regular maintenance shutdown. Instead, “all options for the business, including a potential sale of the business or its assets, will be considered,” the statement said.

The company emphasised that “no decision regarding a permanent closure of the facility has been made at this time.”

Customers will continue to be supplied from current inventories and production at the company’s Omi Plant in Japan.

DPE is 70 percent owned by Denka USA LLC, a wholly owned subsidiary of Denka Company Limited, and 30 percent by Diana Elastomers, Inc., a subsidiary of Mitsui & Co., Ltd.

Yokohama Rubber reported a 56.9 percent year-on-year decline in profit attributable to owners for the first quarter of 2025, despite posting a 9.0 percent increase in sales revenue.

The Japanese tyre maker recorded a profit of 8.53 billion yen for the three months ended 31 March, down from 19.8 billion yen in the same period last year. Business profit fell 3.2 percent to 24.07 billion yen, while sales revenue rose to 275.12 billion yen.

The company maintained its full-year forecast, projecting an 11.4 percent increase in sales revenue to 1.22 trillion yen and an 8.8 percent rise in profit to 81.5 billion yen for the fiscal year ending 31 December 2025.

Yokohama Rubber attributed the profit decline to one-time costs related to its February acquisition of Goodyear’s off-the-road (OTR) tyre business, which it purchased for approximately 143 billion yen.

“Profit from existing businesses was strong,” the company said in its earnings statement. “In addition to increased sales volume for the company’s consumer tyres, mainly in overseas markets, and continued expansion of sales of high-value-added ADVAN, GEOLANDAR, and Winter tyres as well as high-inch tyres, profit was boosted by the MB segment’s MIX improvements and structural reforms.”

The tyre segment, which accounts for 91percent of the group’s consolidated sales revenue, saw a 10.4 percent increase in sales to 250.32 billion yen. Original equipment tyre sales were higher year-on-year, driven by “strong sales in Japan of vehicle models equipped with YOKOHAMA tyres and expansion of shipments for Chinese automakers’ new energy vehicles,” the company said.

Replacement tyre sales also increased, supported by higher sales of summer and winter tyres in Japan, increased sales of high-inch tyres in Europe, and stepped-up sales efforts in Asia.

The MB (Multiple Businesses) segment, which represents 8.4 percent of total sales, experienced a 3.2 percent revenue decline to 23.02 billion yen. This was attributed to lower demand from construction machinery makers in Japan and automakers in North America.

The company described an “upbeat” business sentiment in Japan for the quarter, noting that “a steady recovery in inbound demand and increasing orders for construction and logistics projects compensated for weak consumption by domestic households curbing spending in response to rising prices of consumer goods.”

Overseas, the company observed rising inflation concerns weighing on consumer spending in the United States, while in Europe, “manufacturing industries are rebounding and corporate business sentiment is improving.” In China, personal consumption was boosted by the Spring Festival holiday, but high US tariffs “reduced China’s exports and created uncertainty about the future that is weakening industrial activity.”

Swedish speciality chemicals firm Nynas reported solid financial results for 2024, posting an Adjusted EBITDA of 1,333 million Swedish kronor, marginally higher than the 1,316 million kronor recorded in 2023.

The company, which specialises in naphthenic speciality oils and bitumen products, attributed its performance to operational efficiency and commercial success in its niche markets.

“We are delighted with the progress made during 2024, evidencing our right-sized cost base and a more targeted commercial and manufacturing footprint. We have redefined our strategic direction, positioning Nynas as a speciality chemicals company, enabling the energy transition and setting our course for 2035,” Nynas CEO Eric Gosse said in a statement.

The firm highlighted strong cash generation from operations, which it said would support planned investments and longer-term growth initiatives. Nynas also mentioned the ongoing transformation of its Harburg site with plans to monetise the asset eventually.

All three of the company’s production facilities maintained high operational reliability between 95 percent and 99 percent. The Nynäshamn refinery achieved a notable milestone: in May 2024, it set a new monthly production record for naphthenic speciality oils at 42,000 tonnes.

Strategic pivot towards sustainability

Nynas outlined a strategic shift focused on higher-margin speciality materials with sustainable characteristics. The company aims to strengthen its position in European markets through innovation and sustainability initiatives.

“Nynas is uniquely positioned to contribute to the energy transition. Our strategy reflects our purpose to advance a more sustainable society, and our product development pipeline is fully aligned with this goal," Gosse added.

In 2024, the company received an EcoVadis Gold rating, placing it in the top 5 percent of globally rated businesses for sustainability performance.

With consecutive years of strong financial performance, Nynas indicated it continues to monitor debt capital markets to optimise its capital structure “at the appropriate time potentially”.

The Swedish chemicals producer noted that, having ceased operations in the United States in 2022, it remains largely insulated from recent global trade tensions surrounding US import tariffs. The company imports only minimal feedstock from America, shielding it from potential cross-border trade disputes.
