Dunlop has signed a memorandum of understanding with Cabot Corporation to evaluate the commercial use of circular reinforcing carbon made from regenerated material derived from end-of-life tyres, as tyre makers seek to cut emissions and increase the use of sustainable raw materials.

The agreement brings together Dunlop’s parent, Sumitomo Rubber Industries, and Cabot Corporation to assess whether Cabot’s regenerated carbon technology can be deployed in mass-produced tyres.

Under the memorandum, Sumitomo Rubber will test Cabot’s circular reinforcing carbon — which incorporates reclaimed carbon recovered through the pyrolysis of used tyres — as a potential alternative raw material in tyre manufacturing. The material has not previously been used by the Japanese group in commercial tyre production.

Cabot, which supplies reinforcing carbons to the tyre industry, will in parallel examine how its regenerated carbon technology could be scaled to meet potential market demand if the material is approved for wider adoption.

“This innovative circular reinforcing carbon will be evaluated for mass-produced tyres, and we will accelerate efforts towards its commercialisation through collaboration with Cabot,” said Takuya Horiguchi, General Manager at Sumitomo Rubber Industries’ material research and development headquarters. He said the partnership would help speed progress towards decarbonisation by combining the technical capabilities of both companies.

Aatif Misbah, Vice-President and General Manager of sustainable solutions at Cabot, said the company was committed to investing in technologies that improved both sustainability and product performance. He added that the agreement aligned with Cabot’s goal of supporting a lower-carbon future for the tyre industry.

The collaboration forms part of Sumitomo Rubber’s broader circular economy strategy for its tyre business, known as “TOWANOWA”. The initiative combines a “sustainable ring”, covering processes across the value chain, with a “data ring” that integrates and shares data collected from each stage of production and use.

Sumitomo Rubber said it would continue to pursue the TOWANOWA strategy by reducing its environmental impact while improving tyre performance and safety, with the aim of delivering new value to customers as the industry transitions towards more sustainable manufacturing practices.

Kraton Corporation, a leading global producer of speciality polymers and high-value bio-based chemicals derived from pine wood pulping co-products, a global price increase for all polymer products with effect from 1 April 2026. The price hike will range from USD 440 per MT to USD 700 per MT, or as individual contract terms permit, with the exact price change varying according to the polymer type and production location.

The driving forces behind these significant pricing actions are multifaceted, rooted in substantial disruptions to global supply chains. These disruptions are largely attributed to the ongoing conflict in the Middle East, which has had a cascading effect on logistics. Compounding this issue are the sharply rising costs associated with transportation and essential raw materials.

German chemical group WACKER has announced a price hike across its global polymers portfolio, responding directly to significant upheavals in international commodity markets triggered by the recent military conflict in the Middle East. This geopolitical instability has created pronounced distortions throughout the supply chain, leading to a sharp escalation in the costs of essential inputs. The company is experiencing substantially higher prices for crude oil and natural gas as well as for various other raw materials and logistics services.

To address this challenging economic landscape and offset the considerable burden of increased raw material and transportation expenses, the chemical group is implementing price adjustments effective 1 April 2026. The updated pricing will apply to several key product categories, specifically including polymer dispersions, a variety of resins and dispersible polymer powders. This strategic move is essential for the company to maintain operational stability and continue delivering its products reliably amidst the volatile market conditions.

The final scale of these price increases is not a fixed, across-the-board figure but will be determined by specific variables. It will largely depend on the original source of the product, with goods manufactured at the company’s European and Asian production sites being most affected. Furthermore, the terms outlined in existing customer contracts will also play a crucial role in defining the exact extent of the adjustment, ensuring a tailored approach to the implementation of this necessary price correction.
