LD Carbon has inaugurated Korea’s first and largest waste tyre pyrolysis plant in Dangjin, South Korea.

Located in the Dangjin Hapdeok General Industrial Complex, the plant is expected to begin full-scale operation next month. The plant is spread over 29,800 square metres and features two factory buildings and five silos. The plant has an annual capacity to process 50 kilotonnes per annum (ktpa) of tyre chips derived from end-of-life tyres (ELTs).

At the location, LD Carbon uses a two-step pyrolysis process, first turning ELTs into solid char and pyrolysis oil. After that, the business uses a secondary pyrolysis process to further compress the char and create recovered carbon black (rCB). It is anticipated that the Dangjin facility would generate 20 ktpa of rCB and 24 ktpa of pyrolysis oil, which is a substantial increase above the combined output of 7 ktpa at its current pilot plant in Gimcheon. When compared to traditional carbon black, the rCB generated by the technique is said to lower carbon emissions by up to 32 ktpa.

The company is planning to build plants overseas and intends to join the Asian market soon. It has also struck a 10-year offtake deal with SK Incheon Petrochem for its pyrolysis oil.

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.

Orion S.A., a global speciality chemicals company, has successfully secured the prestigious ISCC – the International Sustainability and Carbon Certification for its manufacturing facility located in Qingdao, China. This significant achievement is the direct result of a rigorous, independent audit process which validated that the plant’s operations fully comply with the comprehensive sustainability criteria established by ISCC.

The certification serves as a formal verification of both the transparency and the complete traceability of the sustainable raw materials integrated into the facility’s production value chain. This milestone is a key component of Orion’s overarching corporate strategy to implement and enhance sustainable practices throughout its international operations.

By achieving this globally recognised standard, the company reinforces its commitment to supplying clients with high-performance carbon black and other speciality chemical products that adhere to leading international environmental and sustainability benchmarks, thereby supporting customer goals for more responsible manufacturing.

Ecolomondo Corporation, a Canadian developer of sustainable technology for recycling scrap tyres, has secured a provisional financing agreement with Export Development Canada (EDC) for USD 2.7 million. The funds are intended to support the final ramp-up phase of its Hawkesbury thermal decomposition plant by covering necessary capital investments and operational working capital.

Following months of negotiation, both parties have agreed in principle to the loan terms, which include augmenting an existing USD 2 million credit facility established by a subsidiary, Ecolomondo Environmental (Hawkesbury) Inc, in January 2025.

Furthermore, EDC has conditionally approved a temporary suspension of principal and interest payments for loans from 2024 and 2025, applicable during the facility's 2026 ramp-up period. This financial arrangement is designed to provide the liquidity required to advance the project to full operational capacity, pending the finalisation of formal documentation.

Jean-François Labbé, Interim CEO, Ecolomondo Corporation, said “We have been working steadily in Hawkesbury, hiring, training, increasing production, increasing sales and, most of all, improving efficiency. This additional financing from EDC is greatly appreciated and should allow the Hawkesbury TDP facility to achieve its full potential.”

Cabot Corporation said it has received improved environmental ratings from CDP, reflecting continued progress in water management and steady performance on climate disclosures.

In CDP’s 2025 assessment, the company was awarded an A- rating for Water Security, up from a B in 2024, and a B rating for Climate Change, unchanged from the previous year. Cabot said the water score exceeded both global and industry averages, recognising its approach to managing water-related risks and implementing sustainable water practices.

The Climate Change rating remained stable year on year, with improvements reported in areas including climate risk disclosure, value chain engagement and industry collaboration.

The latest scores extend a five-year pattern of incremental improvement, achieved amid more demanding reporting standards and rising expectations from regulators, investors and customers.

“We are proud that CDP’s independent assessment reflects our ongoing efforts to enhance environmental performance and transparency,” said Jennifer Chittick, senior vice-president for Safety, Health and Environment and chief sustainability officer. “The improvement in our Water Security score demonstrates our leadership in this critical area, and we remain committed to advancing our sustainability strategy across all domains. This progress was made possible by our dedicated, global team, and we remain focused on driving further improvements in the years ahead.”

CDP assesses companies on environmental impact across climate change, water security and deforestation, using a scale from D for Disclosure to A for Leadership. In 2025, more than 24,800 companies were rated, representing about two-thirds of global market capitalisation.

Cabot said the results underline its focus on transparency and responsible environmental management as it continues to execute its sustainability strategy.
